The visibility shrank at times to less than 100 yards, but then someone called out they had heard a blow and sure enough a right whale. Our first right whale was #2791, an adult female who calved in 2009 and is due to get pregnant.

This year was certainly an anomaly in the Bay of Fundy given the low number of right whales, plus the atypical sightings of sperm whales, pilot whales and white-beaked dolphins. In total, we identified 53 individual right whales (number depending on data analysis) of which there were only 5 mom/calf pairs. We had a successful survey on Roseway Basin and on the way back we found a small aggregation of right whales feeding at the surface southwest of Lurcher Shoals. Colleagues reported small groups of right whales on southern Jeffreys Ledge off Gloucester, MA and around Mount Desert Rock, south of Bar Harbor, ME. These small aggregations spread through out the Gulf of Maine were the trend in 2010.R/V Callisto heading out at dawn on Sept 18 for our bay-wide survey
We have ventured to the far reaches of the Bay of Fundy, outside of our traditional survey area, to look for right whales this season. Last week the team discussed expanding our survey to areas south of Grand Manan Island and farther east toward the southern tip of Nova Scotia - 2 areas where right whales have been seen recently. With only a 2 day weather window, we decided to first complete a thorough survey in the Bay before we went exploring around the Gulf of Maine.R/V Nereid heading home at dusk on Sept 18 after our bay-wide survey
On September 18, R/V Callisto and Nereid surveyed a large section of the Bay and found 9 right whales in the northeast part of the Bay, an optimistic number given the year. The whales were farther northeast than usual and outside of their typical feeding area. So we extended our Bay of Fundy survey by another day to cover the northeastern and westward areas outside of the critical habitat area. To our surprise, we only found 3 whales between both boats. Interestingly though, we saw 56 pilot whales during those 2 days and similarly to sperm whales, pilot whales are deep-diving squid eaters. Speaking of sperm whales, we saw 5 sperm whales during those surveys and have some cool audio recordings that we're going to post soon.

Calanus copepods collected during our survey in Roseway Basin
In the Bay of Fundy, right whales feed specifically on a copepod species called Calanus finmarchicus that are found in dense aggregations at or near the bottom of deep water basins in late summer and early fall. The Bay of Fundy is one of the main feeding habitats for North Atlantic right whales so their absence here suggests something may be going on with the food resource on which they have traditionally depended. This brings us back to our original question - how could unusually warm water in winter affect right whales in the summer?
