Scientific Log

Our days continue to be hazy and cloudy. We are getting more track lines done and are staying “on effort” more frequently, yesterday, we had around 70 sightings of marine mammals.  We are still seeing humpbacks, killer whales, Risso’s dolphins, harbor porpoises, pacific-white sided dolphins, minke whales, beaked whales, Dall’s porpoise, as well as California sea lions, northern fur seals, and elephant seals. The California current is one of the most productive in the world.

Yesterday, afternoon, about 3 miles from Big Sur, a Blue Whale surfaced right on the bow of the ship. It was beautiful to see the whale with the Big Sur coastline in the background.

Personal Log

The days are getting busy with sightings as we continue to work track lines in the southern marine sanctuaries.  Although hazy and foggy, the weather has been quite pleasant.  The ocean has been relatively flat, with little waves and small swells.  This makes it easier to sight blows and marine mammals.

Today I’ll be editing video, and hopefully will have some good footage to share with you. We are trying a new way to get my logs off the ship.  I will still answer e-mail to until Sunday afternoon.
