“Data: More or Less?” by OA Science Manager Andy Rogan

By | Ocean Alliance News | No Comments

Perception of our jobs, as marine biologists, varies enormously and is almost always fairly wide of the mark. The, sadly fairly inaccurate, vision tends to be some variation of endless weeks spent cruising over flat-calm and crystal clear deep blue oceans, interacting daily with a myriad of charismatic ocean life, hair going lighter and skin going darker under an infinitely azure and cloudless sky.

These days, the reality is that less and less time is being spent in the field collecting data. Field work can be incredibly expensive, and more time on the ocean means less time in the office fund-raising. Nowadays there are hundreds of groups collecting data: from big oceanographic institutions such as Woods Hole & SCRIPSS, universities and other academic groups, government organizations such as NOAA and non-profits such as Ocean Alliance. This is of course a wonderful thing. Competition inevitably leads to a more efficient, productive industry. Yet, for the most part, we’re competing for the same resources: more hands being put in the same pots for smaller sums of money.

What this means is that when the time for data collection comes along we need to take full advantage. This puts more pressure on us to collect all the data required in that short period of time, and brings to the fore a familiar question in the scientific world. Data: more or less? Collect too little and you could miss out on crucial information, a seemingly innocuous data point which forms the vital piece of the puzzle. Collect too much, and every extra piece of information becomes more time-consuming, more complex and leaves more room for error (and if you are too busy with your head down recording information, you risk not even seeing the whales in the first place!).

One of the major advantages of SnotBot is that it allows us to collect a high number of samples: a good sample size. Small sample sizes are major bottleneck to most data collection techniques which involve collecting physical, biological samples from large whales. SnotBot changes this, by allowing the researcher to race over to a whale, collect a sample/multiple samples from the same whale, race back to the research vessel, wait for the sample to be removed and appropriately stored before flying off to the next whale and repeating the process. Of course, if I had my head down recording every single variable of each flight, this would considerably slow the process. So where does the balance lie?

IMG_3816

This was a conundrum we had to figure out, to decide what was important and what wasn’t. With well-established measures of data collection, many scientists live by the expression, ‘less is more’. Collect only the vital pieces of information, making for a more efficient and more easily analysed data set with far less room for error. SnotBot is not a well-established measure of data collection. Indeed much of the value of these early expeditions is about testing different drones and collection devices in an effort to determine the most effective and practical ways of collecting as much exhaled breath condensate, or ‘blow’, as possible. As we take these first steps into the world of SnotBot, we don’t know what the most important factors will be in shaping whether or not we get a sample and how large that sample will be. As we look to establish SnotBot as a mainstay of marine mammal research, it is imperative that we collect as much data as possible. In 5 years’ time we don’t want to look back and say, ‘if only we had collected this piece of information or that on every SnotBot flight’. We will be able to look back at mountains of data and determine what the most important factors really are. Then, and only then, will we be able to look up a little more often and get to enjoy the experience of being in the company of whales.

Having said that, it might be a stretch to say that we didn’t have many good encounters with whales…

SnotBot Sea of Cortez Blog #1 from John Graham

OK, so stop me if you heard this one….

A German, two Brits, and a Yank are in a small wooden Panga boat off the coast of the Baja Peninsula using a drone to collect whale snot….

Doesn’t sound familiar? Well why should it? This one was written just weeks ago, but in the making for several years. Although this opening screams for a side-splitting punch line, I have none, for this is no joke. After reading this, you may want to store it away under the category of “You were doing what?” as part of the Bizarro Files.

This blog is just Part One of a series in which I intend to take you on a journey as seen through my progressive-corrective lenses. All of us who participated in this expedition were given the task of writing down their own individual experience. I’m the tech guy/ engineer on this mission, but my goal in writing these blogs will be to “focus” more on the trek with smatterings of geeky, techie stuff sprinkled in. I’ll try to keep it fresh and not to be too redundant of past articles.
The Ocean Alliance SnotBot crew consists of what is fondly referred to by its fearless leader as the A-Team. Not unlike the popular ‘80s television series, the group consists of characters in their own right; Iain Kerr (group leader and drone pilot), Andy Rogan (scientific researcher), Christian Miller (photographer/ documentarian), and me, John Graham (engineering tech). The mission is to perfect the technique in which we collect data rich, liquid exhalation, also known as “snot”, from our cetacean subjects. Spoiler Alert…….. It was a resounding success!! But I’m getting ahead of myself.

Following up our “blow-catching” drone debut last September in Patagonia, Act 2 finds our ragtag team in the Sea of Cortez, and for those of you who are geographically challenged, such as me, that is off the Baja Peninsula in Mexico. Our gear consisted of 16 very heavy and oversized waterproof shipping containers, also known as Pelican cases, and personal backpacks. The night before our departure, my wife Rebecca was pulled into the madness that was my packing process. I stood on the bathroom scale, straining to hold the over-stuffed equipment trunks in my hands, and due to my obstructed view, Rebecca recorded the results. I than subtracted my own weight to get the final poundage of the gear. 50 pounds is the cut-off for check-ins without incurring a huge surcharge. It was the first and only time in my life that I wish I weighed more, because in my mind, the more I weighed, the less the bags weighed. This was my feeble attempt to get the luggage to be within the TSA limits. All this research gear was necessary because you never know what you’ll encounter while doing research in remote locations. Small hand tools, check. Battery powered tools, check. Panty hose, check. Wait…What? (I’ll explain later.) We started our journey by leaving from Logan Airport in Boston and landing in Los Cabos San Lucas, you know, the place where the Love Boat would “set a course for adventure”. And indeed it was truly to be an adventure. After a brief overnight stay and having the Mexican Customs Department graciously lighten our load of Pesos as “payment” for allowing us to bring our plethora of gear into their country, we headed out on a 10 hour road trip.

Desert drive

Desert drive

The vistas were ever-changing with diverse terrain ranging from deserts replete with huge prickly cacti standing like silent sentinels strewn across the landscape; to its counterpart, the oases, with fields of lush green farmland and small ponds used for irrigating the crops. This is followed by mountainous roads so windy that the famous “crookedest street in the world”, Lombard Street in San Francisco, should hand over its crown and admit defeat. I would consider it one of the most beautifully diverse drives I have ever taken. Apart from the confusing and dangerous road rules, like random stop signs on the main highway or having to play a game of “chicken” with a tractor trailer in order to pass, the drive was quite enjoyable. There were however, the occasional sheer cliff drop-offs void of all those pesky guardrails with near-by asphalt adorned with the skid marks of vehicles not so lucky to negotiate the turn. This served as a not so gentle reminder to keep our eyes on the road and not be seduced by the scenery.

Just as the sun was setting, we arrived at our destination, San Ignacio. It is an amazing little town, whose image is easily conjured up by anyone who may have seen a Clint Eastwood spaghetti western. Passing multi-colored buildings of stucco and a beautifully crumbling old church in the center of town, we made our way to our hotel. It wasn’t difficult to find, being it was the only one around for miles. Upon our arrival in town we were also exposed to the amazing aromas that wafted in through the van’s open windows. The drive there had provided us little in the terms of substantial nutritional intake, just the usual road trip fare of cookies, chips, and candy bars. We quickly unpacked all our gear into the two rooms that served as a brief respite to recharge our batteries after the long drive, than we headed off on foot into town to find the source of the delicious food bouquet. The sounds and smells of fajitas with chicken and beef grilling pulled us towards a little cafe with outdoor seating. These sensory cues draw me back to that place in time as I sit to write this. After sampling the local cuisine, we headed back to the hotel for some much needed sleep. We were informed by the hotel manager that on that very night of our stay, the annual Miss Baja Pageant was to take place. Sounded interesting until we discovered that right outside our rooms was the runway for the eager contestants and the festivities didn’t get started until 10:00p.m… This made it difficult for all of us to get sleep, but poor Christian must have drawn the short straw when it came time to choose roomies. The blaring music being emitted from the huge speakers outside was probably a welcome distraction compared to the noises from within his room. He showed great fortitude by not smothering me in my sleep with a pillow in pursuit of muffling the snoring bear in the adjacent bunk with only a night stand and Gideon’s bible as a barrier.
Morning came quickly, as we repacked up the car, grabbed a quick breakfast of huevos, jamon, y frijoles (eggs, ham, and beans) from a roadside tent stand and hit the road for San Ignacio Lagoon. The remote camp was to be our home for the next 5 days. After shooting some “B roll” (that’s movie lingo for the clips that act as filler between the actual action and help set the mood), for our cameraman/ documentarian, Christian, we were on our way. It was a bright sunny day, dirt roads, more cacti, vultures, and a van full of gear and eager SnotBot crew members. The only thing left behind was our memories in a cloud of dust as we made our way to what brought us to this country in the first place, to research Grey Whales by use of our drone platform.

SnotBot Sea of Cortez Part 3: Blue Whale

By | Ocean Alliance News | No Comments

Two remarkable people joined us in La Paz to document the second (and last) leg of our Sea of Cortez expedition. Adrienne Hall from Sound Off Productions (soundofffilms.com) and wildlife cameraman Tom Fitz (http://fitzpro.tv). Adrienne has worked on a number of projects with my good friend Louie Psihoyos (“Racing Extinction” & “The Cove”) and Tom and I met at a friend’s wedding over 20 years ago.

Tom and Adrienne

Tom and Adrienne

 

By 8:00 am the SnotBot team were in a 22 ft panga heading out into Bahia La Paz both excited and a little anxious. We’d had a very productive time in Baja Mexico but we wanted to put the icing on the cake – we needed to further validate SnotBot as a scientific tool, and to do that we needed to fly with at least one more species of whale and this was the last day on the water, the last day of the expedition. Dr. Jorge Urban was at the helm along with two of his students from the University of La Paz and Adrienne and Tom were in a second boat to get a different filming perspective. So we had the A team, we had DJI drones, we had great weather, we just needed whales.  As we headed offshore I joked with Dr Urban, “OK Jorge we need a blue whale today!” In spirit, he smiled and replied,  “No problem amigo!”

Drone Launch

Drone Launch

And two hours into our search that’s what happened. We saw a blow a long way off (still too far off to confirm what species, but it did not look like a humpback blow). My heart was racing as the boats sped towards where we had seen the blows.  After 10 minutes of high speed running the boats slowed down and we immediately launched a SnotBot. Within seconds we saw a blow, still a long way off.  Luckily the Inspire 1’s top speed is close to 50 mph so I raced towards the whale and was soon close enough to see it though my FPV camera system…. and OMG – it was a blue whale!  I cannot describe my feelings as I approached this remarkable animal gliding through the water. After almost 30 years in this business and a British understated reputation to maintain, I have to admit that my hands started shaking and yes I made a mess of my first approach and did not get a blow sample.  I did not care though, the experience of flying SnotBot over the largest animal that has ever lived on the planet was an experience of a lifetime. To put this animal’s size into context: this is the largest animal that has ever lived on the planet; an adult blue whale’s tongue can weigh 6.5 tons; the heart is so big that a human adult could climb into one chamber.  Our blue whale was stunning in the crystal clear water, seeming to swim effortlessly.  After it dove I just left the drone hovering above its footprint and looked around at the rest of the team who were all ecstatic – last day on the water, beautiful weather and we were with a blue whale. I have only ever seen a blue whale once and when you look at the photo below you realize that a drone’s eye view is incomparable; it’s the ultimate viewing experience. Look at its features, how the eyes protrude so that the animal can see forward; look at all of the different musculature and markings on the animal; just look at its amazing color.  So often with SnotBot we focus on the physical data we are collecting from the blow: DNA, microbiomes, pregnancy and stress hormones, but here we can see that even the photos and video that we take have enormous scientific, educational and emotional value.

Blue body & boat

The whale was not coming up in any predictable manner (position-wise), but it was keeping pretty regular dive times (approximately 10 minutes).  So to be safe, we would prep for drone launch at eight minutes and launch at around eight and a half minutes and I would hang in the air 25 feet up looking and waiting for a blow.  This whale’s first blow was always huge, the second big and the third pretty wimpy and the animal would dive right after the third blow, so I had to get there for the second blow.  It took two more tries. I flew down the length of the body just as the whale came up and we caught a massive blow (there is even a rainbow in the blow) well over 80 microliters and just amazing photos and video.  We had 3 more blue whale blow captures that day before we left the animal, totally stunned by the whole experience, with remarkable data, footage and emotions.

Blue Snotted

I think that it is important to pause here and remember that there is no shortcut with the scientific process. We have spent years developing SnotBot working with many volunteers, conducting endless tests with more than enough failures, and a few crashes ashore and over water.  For the first leg of this expedition we spent three days flying into grey whale blows with 5 different snot collection experiments – a total of 41 flights, all of which collected snot but we made no progress collecting snot sample sizes bigger than we collected in Argentina until the 6th and last experiment. Raising funds for this work has also been a tough road, because it was new and experimental. Yes the Kickstarter campaign was successful, but for a small non profit, developing the Kickstarter campaign and running it all the way through to the fulfillment process took up an inordinate amount of staff time and costs. Five years ago pretty much everyone laughed at the SnotBot idea yet here we were collecting samples from blue, humpback, grey and southern right whales. Success is never guaranteed, hard work is – so to have hit the ball out of the ball park on the last day was an experience that is hard to define.  I have spent much of my life looking at whales from an oblique angle from a boat.  In one of our first experiments together in 1988 Roger Payne and I were flying helium balloons and parasails in Argentina trying to get up into the air and here we were 27 years later getting the perfect aerial view and I can tell you it did not disappoint!

Parasail and baloon

We learned so much on the last two expeditions; we better understand what the challenges are ahead of us and what our current limitations are. At the end of the day, though, SnotBot has been an unqualified success – the capacity and value of drones as marine mammal research tools has been validated beyond our initial expectations. The journey is by no means over though. I hope that you will stay with us; we are going to keep pushing this work forward and we hope that you will continue to support us. If you are interested in contributing to this work at any level or know someone who might want to help, please let us know.  Also be advised that there is SnotBot SWAG available in our store! http://shop.whale.org

I have to thank all of you out there who are reading this for joining us on this remarkable journey.  To the many supporters without whom we could not have done this work – thank you, thank you.  My deepest thanks also go to the staff at Ocean Alliance for being the foundation upon which this work stands. Last but not least I want to thank my wife and daughter, my drone heaven has been their drone hell, my wife posted on her Facebook page just before we left “Must be a SnotBot expedition coming up, I have a drone in the bathtub, drone parts all over the dining room table and two drones on my bed.”

SnotBot Sea of Cortez: Part 2

By | Ocean Alliance News | No Comments

The first leg of the SnotBot Sea of Cortez expedition was to San Ignacio lagoon, where the accessibility of grey whales gave us an opportunity to test a number of different snot sample collection techniques.  After working with fairly social Southern right whales and very social grey whales, the work was about to get a lot harder.  While we had developed a very successful sample collection platform with the DJI Inspire 1 during the first Leg, the question was could we collect snot from other species of less social whales such as humpback, blue & fin whales?

So after 5 productive days in San Ignacio Lagoon, we packed up our 16 bags and made the 12-hour drive to La Paz for Leg 2.  I thought that this drive was going to be very boring with hours of endless desert. While we did have plenty of desert, the countryside was spectacular, driving along coastal roads in and out of low mountainous ranges.  The scenery kept changing from desert to dry river beds where greenery was abundant and human agriculture evident. I have seen so much of Mexico from the sea so it was a real pleasure to have this terrestrial counterpoint.

We arrived in La Paz late on Friday night with a message from Dr. Jorge Urban that it would be too windy to go out on Saturday.  As disappointed as we were to hear this, it did give us a day to organize our equipment, buy the items that we could not get in San Ignacio, and meet the film team, Adrienne & Tom, who had come to document our work for an out-of-house project (more about that later).  It was also a luxury to have a real shower, plug our battery chargers into every socket in the room and connect to the Internet!!

Hotel room

Sunday morning we were up at 6:30 and on the boat by 8:00.  Dr Urban (who I have known for over 20 years) from the University of La Paz was at the helm of his 22 ft panga, so we knew that if there were whales out there that we were with the best man in town to find them.  Alas,  Jorge had some bad news to share. The El Nino was wreaking havoc with the Sea of Cortez ecosystems, both marine and terrestrial, and his team were not seeing the typical patterns of whales or abundance – he had just postponed a satellite tagging project because of this.  With those thoughts in mind, we headed out in the Bahia La Paz.  Bounded by the Baja peninsular to the west and the islands of Espirito Santo and Partida to the east, Bahia La Paz extends almost 30 miles north from the city of La Paz and is on average 20 miles wide. These are (typically) very productive whale grounds, and as we spent our first day searching the bay we were regaled with stories of frequent past encounters with humpback, fin and blue whales and occasional encounters with orcas and sperm whales.

We covered over 100 sun-blistering miles the first day, stopping every hour to look and listen. Despite the optimal conditions we did not see a single blow. We returned to our hotel that night tired, sunburnt and a little disheartened.  This is the business though, so the next morning we were in the panga by 7:30 and back out on the water.  Today our guide was Iram, another seasoned biologist from Dr Urban’s team.  Alas the day did not go much better; we did put our DJI drones to work, though, sending the Phantom 4 up to 380 feet every hour using it as an eye in the sky.

As effective as the Phantom 4 was in increasing our spotting range, we still did not see any blows, and by 4:30 in the afternoon the wind had picked up to 15-20 knots so we headed back in.  We were quite close to the city of La Paz when we saw a blow and quickly identified it as a humpback whale.  Typically in conditions this windy we would not try for a blow collection (above 15 knots the wind lays the blow down and the chances of more salt water in the blow increases).  But considering that this was the first whale that we had seen in 3 days, we went for it.  We had moderate success, but every now and then we took a wave over the bow of the boat. This was not good because we had a boat full of electronics, 3 drones and supporting equipment along with close 80K of camera equipment (Christian & Tom both had Red cameras).  So we had to abandon the work and head back into port.  As you can imagine, by this time I was really sweating it (and not because of the heat). We had a very successful first leg, but we needed to validate what we had learned with other species of whales. That night I called our logistics and expedition coordinator, John Atkinson (in Canada), to set up a spotter plane for the next day. We did not have a budget for a plane but we had to find whales. We set it up so that we would spend an hour and a half driving the panga out into the bay and then we would call the plane.  Clearly the whale gods were on our side. Right when we were about to call the plane I heard Adrienne shout BLOW.  Everyone leaped into action, and less than 20 minutes later we had our first humpback whale sample and it was spectacular – our petri dishes and the Inspire 1 were dripping with snot.

Dripping drone

We stayed with this animal for the next few hours, keeping the panga away, but making a number of close approaches with the Inspire 1.  Andy was timing the animal’s dives, which were running at about 9 min. Our procedure was as follows: at 8 min we would prep the Inspire 1; at 8 min 30 sec John Graham would launch the drone and I would hover above the boat ready to go.  Once we saw a blow, my challenge was to get to the whale in time for the second blow.  Once I saw the whale on the surface, I would race the drone towards it and then get into my FPV position (sometimes this would be very disorientating because I would have a drone’s eye view of the world but the boat would be bouncing out of sync with my view).  The whale seemed to like Andy because once he shouted “Should be coming up any second now” and within 5 seconds the whale surfaced. Our drone and launch protocols, our practice as a team, our development of the collection methods all seemed to come together with great results, so we were living the SnotBot dream.  Once when the whale was down Christian sent up his Inspire 1 to film our boat underway, next thing you know the Humpback breached in the frame with our boat in the picture—absolutely blooming amazing.  We went home that night over the moon. Certainly we needed to test SnotBot with other whales, but it looked as if we had a winning formula, all of this work had been caught on camera by two remarkable cameramen, and we still had one day left on the water……. and OMG what a day that was! Ill report on our last day in my next blog.

Helping Sea Shepherd Capture Nighttime Drone Footage

By | Ocean Alliance News | No Comments

Earlier this year, Ocean Alliance CEO and resident drone expert Iain Kerr helped Sea Shepherd Conservation Society put together a drone package to support Operation Milagro II in the Sea of Cortez.  Operation Milagro II was launched in November 2015 with the objective of stopping the extinction of the endangered vaquita porpoise, principally through entanglement in gill nets.  The vaquita are one of the world’s smallest cetaceans, and only inhabit the northernmost part of the Gulf of California.  They are the most endangered marine mammal in the world, with the population suspected to be only a few dozen individuals.  Although all gill nets are dangerous for vaquita, the greatest threat is posed by the gill nets used to catch the Totoaba fish due to the size of the mesh.

Having set up successful daytime patrols and working closely with the Mexican government, Sea Shepherd believed that the poachers might be setting gill nets at night.  Sea Shepherd staff called Iain Kerr and explained the problem.  After a series of conversations, Iain suggested the DJI developer drone Matrice 1 and the FLIR Vue Pro night vision thermal camera. “The Matrice is a very adaptable platform.  Crucial for this project was reliability of the DJI product, the 40 minute flight time, 3 mile range, and plug and play capacity of the FLIR Vue Pro Night Vision camera,” said Kerr.

Just this week, Iain received an email from Sea Shepherd thanking him for the support and success of this collaboration.

“We are over the moon with these results,” said Kerr. “So often we hear bad news about drones.  This project proves the enormous potential of drones as wildlife conservation tools.”

SnotBot Sea of Cortez: Part I

By | Ocean Alliance News | No Comments

SnotBot Sea of Cortez was a remarkable expedition with the highest highs and the lowest lows. I was lucky to have a remarkable team with me: technician John Graham, scientist Andy Rogan and photographer/videographer Christian Miller. We had great weather, food, and, most importantly, whales. Here is part one—San Ignacio Lagoon and gray whales.

SnotBot Patagonia proved that we could collect snot from whales using a drone. The primary goal for SnotBot Sea of Cortez was to see if we could increase the snot sample size so that we would have enough to use for all the different analysis that we are interested in.  The secondary goal was to collect snot from multiple whale species to make sure that our previous collection success was not a fluke (pun intended).

In Patagonia our average sample size was around 20 microliters (one small drop of water).  For the Sea of Cortez we set ourselves an optimistic goal of 80 microliters. Imagine building a go-kart that does 50 mph on the first run and taking it home and saying next time we want to go 200 mph.  The Sea of Cortez is a very diverse region species-wise so we were also hoping to encounter gray, humpback and blue whales.  Last but not least, we wanted to do this work with off-the-shelf drones, so that this work can be replicable and scalable, so we were lucky to have the world leader in drone development DJI providing us with the drones. We took with us the new DJI Phantom 4 and the DJI Inspire 1.

Working with Dr. Jorge Urban’s team from the University of La Paz, our first study site was San Ignacio Lagoon. The gray whales are so friendly here that you do not need a SnotBot to collect blows as they come right up to the boat to be touched and you can’t help but get “snotted.”  Because of this, though, they were the perfect whales for us to conduct multiple flights into blows to test our different snot collection devices. We had a total of five different snot collection devices and procedures that we wanted to test.

One would think that drones would not be good snot collection tools–the whales are blowing the snot up, but the drones, to fly, are blowing air down. Technically we had opposing forces.  For our first set of experiments we used different collection tools at the end of a pole, extending the collection device out of the drone’s prop wash.  We ran multiple flights with five different collection methods:

  1. Nitex weave cloth (very similar to wedding veil)
  2. Stockings on a wire frame (this method has been used on a long pole)
  3. A different weave and texture Nitex cloth
  4. A number of Petri dishes on a T bar (an upgrade of our Patagonia method)
  5. A medical sponge material developed in Malden, MA for hospitals.
Collection methods

Collection methods

The idea is that the different holes, size, and consistency of the materials will collect and hold the snot with different levels of success. The problem with this method is that you have to get the snot out of the capture material after the flight, so we brought a centrifuge to Mexico so that we could spin the snot out from the collection material. The Nitex cloth balls were split up into 4 different pieces so that each section could just be dropped into one of the centrifuge tubes after a flight.

On Monday, Tuesday and Wednesday morning we flew over 49 flights into gray whale blows.  We were getting into the blows okay and we were getting amazing footage but we were not increasing our sample size by any significant amount.  So on Wednesday afternoon, we attached two 4 inch Petri dishes and one 6 inch petri dish on top of the DJI Inspire 1 with industrial grade velcro.  The idea here was not to get out of the downdraft created by the drone but to use the down draft of the drone to collect snot for us. We believed that the Inspire 1 would be very well-suited to this because while most drones have big round bodies, the Inspire 1 has a long thin body and the propellers are raised above the body. So we put Petri dishes onto the Inspire 1 (see photos of the petri dishes hanging over the body) flew into a gray whale blow and we hit the jackpot.  The petri dishes were literally flooded in snot–Andy Rogan estimated a minimum of 80 micro liters from just one blow.  If we could fly into more than one blow from an animal (and we did) we would collect more than enough snot for the analysis we wanted to do and probably as much snot (or more) than people who have used long poles to collect snot from whales.

I should mention that on my very first flight in the Sea of Cortez I crashed and critically damaged a drone. Not a good start. To be knocking the ball out of the ballpark three days later was more like the script for a movie than an actual scientific experiment.  On Thursday morning we went back out to the gray whales with the Inspire 1 and with ten more flights (a total of 59 with grey whales) we consistently repeated our success from the day before.

It should be said that even this experienced team was overtaken by these amazing animals on occasion. I fly the drones FPV (first person view) so I am not looking at the world around me–I have my head pushed against a Hoodman screen cover so that all I can see is a drone’s-eye-view of the world on my IPad. During one flight no one was responding to my question so I took my head away from the screen to see three guys hanging over the side of the boat hugging a whale. Just before we headed back in on the last day I took off my flight and screen harness and managed to touch a whale myself, which Christian Miller caught on camera.

Thursday afternoon we packed up all of our equipment in preparation for the 12-hour drive back down to La Paz where we hoped to find humpback whales and maybe, just maybe, blue or fin whales.  We had been warned that El Nino had had a severe effect on the region and that they had not been seeing the number of whales that they had seen in years past. At this point we did not care – we had over 80 micro liters of snot from a single blow so goal # 1 achieved.  Mission Accomplished!
