This is the fourth in a series of dispatches sent from the field during the recent SnotBot Alaska expedition. The first dispatch can be found here.
Day 1 we had a 100-mile passage down from Juneau to our study site Frederick Sound and our port of operations Kake, the passage was tough but we were very excited to be in SE Alaska.
Day 2 the weather remained bad, blowing 15 Knots plus but we collected 2 Snot samples.
Day 3 bad weather again but we collected 5 samples.
Day 4 the weather cleared by midday, the wind and seas calmed down and we collected 8 samples.
Yesterday (day 5) we had a bit of fog in the morning with minimal wind and calm seas and we collected 15 Snot samples.
Total samples so far 30!
Our goal was a minimum of 25 samples so we are over the moon. On top of this we have seen some of the most spectacular whale behavior I have ever seen. I am now spoilt, I just can’t imagine studying whale’s from only a boat and not having and eye in the sky.
As much as I hated the bad weather it did give the team time to work out how to work together on such a small boat and it gave us a chance to shake down our routines and protocols. Also we have learnt a tremendous amount about flying over Humpback whales and whales in general. We have been making a punch list ever day of variables that we should be considering during our interpretation of the data such as, whale direction and wind direction. If the wind is blowing at 90 degrees to the whale’s passage, then you have to run parallel (downwind) of the whale to collect snot. If there is a group of whales, you always want to pick the upwind whale so that a second whale does not contaminate the sample. We are now up to about 40 variables and we are planning on writing a report for National Marine Fisheries so that others can benefit from our experiences.
We saw a lot of bubble net feeding today by individuals and groups, just spectacular. We also saw a lot of breeching and pec flapping. I even saw two whales lunge in opposite directions next to each other.
We have three days left in Frederick Sound and then the passage back to Juneau. Tomorrow we hope to test a new drone a partner to SnotBot – a drone that we hope will give us a completely different insight into the world of whales than does SnotBot. Another piece of data for the biological jig saw puzzle.
Onwards Upwards, Fingers crossed.
All the very best.
