The second week of IMMB 2015 flew by faster than the first. The students were busy with more seal surveys, another whale watch, a fish lab, a scrimshaw art project, a seal necropsy, a post-necropsy swim call (water temp = 56 degrees!), and a stranding response to the rarely seen Delphinus inflatus. In addition, each student completed an oral presentation for our class symposium, Seal Week – a theme that we modeled after Shark Week – to educate people about the misconceptions about the recovering seal populations of New England.
The first week of Introduction to Marine Mammal Biology 2015 is off to a great start. We have seven students who are giving it their all – it’s a lot of material to cram into two weeks! Highlights include: hikes around Appledore Island, a skulls and skeletons lab where students solved bone puzzles, a whale watch, a Duck Island seal survey, bioacoustics lab, porpoise dissection, and of course – lots of gorgeous sunsets.
“It’s tough to make small talk with a stranger – especially when that stranger doesn’t speak your language. (And he has a blowhole.)”
RadioLab is a FANTASTIC radio program that presents engaging [and often fascinating] stories about science. (Co-host Jad Abumrad recently won a MacArthur “Genius” Fellowship for his work on this and other programs).
This episode focuses on dolphin intelligence and communication. D. Graham Burnett, science historian and author of “The Sounding of the Whales: Science and Cetaceans in the Twentieth Century”, gives a great analysis of why people care so much about whales and dolphins. Act Two, describing a wild dolphin communication project in the Bahamas gives a very realistic account of why field work can be so difficult – and why projects can go for several years with no results.

We took a trip to [foggy] Duck Island for a gray seal monitoring survey, and then Mary showed students how to complete abundance estimates and photo ID from photos of haul out sites. Everyone seemed to enjoy the photo ID process, especially choosing names for seals based on distinguishing marks (photos above). A large thunderstorm, with lots of lightning, in the afternoon gave way to a double rainbow during dinner. Around 9:00, the skies lit up with heat lightning as well as fireworks from many towns on the New Hampshire and Maine coasts.

Christin Khan, at NOAA Fisheries in Woods Hole, keeps a great blog where she posts photos and aerial survey reports. Check out her fantastic photos from a recent flight in the Great South Channel (Gulf of Maine). Besides right and sei whales, who are feeding on plankton, they also saw almost 100 basking sharks. The all-you-can-eat lunch buffet is definitely open!

This interactive Google Map (from colleagues at NOAA Fisheries) will give you sightings from recent aerial, shipboard, and acoustic surveys for right whales. I found it useful this past spring when planning trips to Provincetown to see whales from the beach.
The [beloved] NOAA Ship Albatross IV was decommissioned in 2008, and eventually sold to the Universidad Autonoma de Tamaulipas in Mexico. Here is a video of the A4 arriving at the CIDIPORT Research Center. I had dreamed of purchasing this vessel, refitting it (Steve Zissou style), and using it as a charter vessel for all of my friends and colleagues. Some dreams are not meant to be…
