About Our Scientists

NOAA Fisheries research biologist Patrick Ressler.

Patrick Ressler works with the Alaska Fisheries Science Center’s Midwater Assessment and Conservation Engineering program. His research interests include understanding how physical oceanographic features influence the distribution of zooplankton, fish, and other higher predators, applying acoustic field methods to the study of patterns in zooplankton and fish abundance and distribution, developing acoustic indicators for use in fisheries management and stock assessment, and learning how marine ecosystems respond to climate change.

Prior to joining NOAA Fisheries, Patrick attended Bucknell University in Lewisburg, PA (B.A., Biology, 1996), and after spending a semester abroad learning oceanography and nautical science aboard a large sailboat, he came home wanting to go back to the ocean. After learning about biological oceanography, acoustics, and marine mammals at Texas A&M University in College Station, TX (Ph.D., Oceanography), he spent a year as a post-doc at the Hatfield Marine Science Center in Newport, OR studying oceanography and euphausiids (‘krill’) of the California Current.

NOAA Fisheries research biologist Kirsten Simonsen.

Kirsten Simonsen also works with the Alaska Fisheries Science Center’s Midwater Assessment and Conservation Engineering program. Her primary interests are in fisheries ecology, examining the roles of habitat and the environment on the ecology of marine fish.

Prior to joining NOAA Fisheries, Kirsten went to Roger Williams University to pursue a degree in Marine Biology (B.S., Marine Biology, 2001). She spent a year after college working at the University of Maryland Chesapeake Biological Laboratory, before moving back to New York to work for a non-profit marine biological field station, teaching high school interns and various school groups about marine ecology. In 2004, she moved to Baton Rouge, Louisiana to pursue her graduate degree in the Department of Oceanography and Coastal Sciences. Here, she studied the effects of an inshore artificial reef on the distribution and feeding ecology of estuarine fish.
