by Jamal Moss  July 7, 2013 We caught a huge Cyanea capillata during a 75m deep midwater trawl today. It was exciting to encounter such a large specimen. These coldwater jellies can grow to be quite large. They are pelagic during most of their life and typically settle in shallow Read More

The Flip Side

Tags: Gulf of Alaska Project Field Notes

by Russ Hopcroft  May 7 2013The logical place to start is where we left off nearly a week ago, atwhich point we were on the Fish and Wildlife Service vessel Tiglax getting hammered by badweather, and NOT the happiest collection of people.

There were multiple humpback whales doing this in order to corral either small fish (pacific herring) or euphausiids Read More
