Anna McLaskey, UW Oceanography

Graduate Student, University of Washington School of Oceanography

Bio: I’m a PhD student in the University of Washington’s School of Oceanography. My research focuses on how ocean acidification affects crustacean zooplankton, such as copepods and krill, which are at the base of the food web and support fish, seabird, and whale populations. I grew up on San Juan Island, WA and have been in love with the ocean for as long as I can remember. My previous cruise experience has been within Puget Sound and I am looking forward to working on the open ocean, especially on a cruise with such a wide range of projects.

What I’m doing on this cruise: This cruise is a chance for me to observe two species I usually study in a lab setting – the krill Euphausia pacifica and the copepod Calanus pacificus – in their natural environment. In the lab, I’ve had to work really hard to create seawater chemistry conditions that mimic those of the California Current in order to see how these species are affected by ocean acidification. Out here, because the oceanographers are analyzing the chemistry at every station we visit, I’m able to collect zooplankton samples and know exactly what conditions they’re experiencing.
