Day 13: 19 April.
We’ve arrived at our Northeast most tracklines over the Hague line and into Canada. This area is great habitat for beaked whales and we were hoping to see a lot. Though the weather was less than ideal, we had over 70 individual sightings, the most sightings of this leg. As expected, many beaked whales were seen with lots of breaching activity, even as close as 300 meters from the ship. In addition, there were several common dolphins, with one large group of approximately 300 individuals, striped dolphin, Risso’s dolphin, finback whales, humpback whales, and one sighting of a blue whale.
On the seabird front, there were many individual sightings with puffins, dovekies, gulls, Leach’s storm-petrels, sooty shearwaters, Northern gannets, and great looks at several jaegers.Another black-capped petrel sighting was particularly interesting so far north in Canadian waters.
The deep water enabled continuous towing of the acoustic array throughout the day while two MARUs were also deployed. Oceanographic sampling via CTDs and bongo fine mesh nets continues as well as our first deployment of the video plankton recorder. More to come, next blog…Bermuda petrel, oh ya!!
