Recent Sightings on Marine Mammal Survey

June 10, 2011

On 8 June we started transect line 21, the most western shelf-break line, but were weathered out by high sea state.  After breaking effort we steamed east about 120 nm to the southern end of transect line 10.  On 9 June we surveyed lines 10, 9, and half of line 8.

The weather and sighting conditions on the 9th were the best so far, and it was a very productive day.  Typical species sighted were: short-beaked common dolphins, offshore bottlenose dolphins, Risso’s dolphins, striped dolphins, sperm whales, humpback whales, and fin whales. We also sighted Cuvier’s beaked whale, other unidentified beaked whales, and a Kogia.

During the evening we transited to the shelf/slope region (2,000 m isobath) preparing to survey our first slope water to Gulf Stream North wall survey line.

Today we began surveying line 23.  We broke effort at 1400 because increased sea state that did not allow for effective searching.  Based on the weekend marine forecast, we are now headed back to line 8 at Hydrographer Canyon.

Ever wonder how great images of bow-riding common dolphins like this one are caught by a photographer?

Sasha, one of our observers, did it this way.  Note the safety harness!
