Bomb-produced radiocarbon validation of growth-increment crossdating allows marine paleoclimate reconstruction

Creator:: Kastelle, Craig R., Helser, Thomas E., Black, Bryan A., Stuckey, Matthew J., Gillespie, Darlene C., McArthur, Judy, Little, Diana, Charles, Karen D., and Khan, Reziah S.
Abstract:: The bivalve Pacific geoduck (Panopea generosa) has been used in the eastern North Pacific Ocean to create proxies for environmental factors such as temperature and oceanographic conditions. This type of research depends upon accurate age determination of Pacific geoducks, which historically was based on shell growth-increment counts. A recent study...

Tracking North Pacific Humpback Whales To Unravel Their Basin-Wide Movements

Creator:: Palacios, Daniel M., Mate, Bruce R., Baker, C. Scott, Hayslip, Craig E., Follett, Thomas M., Steel, Debbie, Lagerquist, Barbara A., Irvine, Ladd M., and Winsor, Martha H.
Abstract:: In 2014, Oregon State University (OSU) initiated a multi-year project to study humpback whale (Megaptera novaeangliae) migrations in the North Pacific Ocean using satellite tracking technology in combination with genetic and photo-identification (photo-ID) analyses. The study is highly relevant to management, given the need for new information arising from the...

Status of the European Green Crab, Carcinus maenas, (aka 5-spine crab) in Oregon Estuaries. Report for 2023

Creator:: Yamada, Sylvia Behrens, Royer, Cameron, Schooler, Shon, Randall, Andrea, and Fisher, Jennifer
Abstract:: The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. A strong year class arrived during the 1998 El Niño, but numbers decreased and remained below 1 per trap per day until the arrival of the 2015-2016 El Niño. Since then, numbers...

Confirmation of right whales near a historic whaling ground east of southern Greenland

Creator:: Mellinger, David K., Nieukirk, Sharon, Klinck, Karolin, Klinck, Holger, Dziak, Robert P., Clapham, Phillip J., and Brandsdóttir, Bryndís
Abstract:: North Atlantic right whales (Eubalaena glacialis) were found in an important nineteenth century whaling area east of southern Greenland, from which they were once thought to have been extirpated. In 2007–2008, a 1-year passive acoustic survey was conducted at five sites in and near the ‘Cape Farewell Ground’, the former...

Abstract:: conservation and ecology. Currently, the most widely used methods for obtaining such estimates involve either sighting animals from transect lines or some form of capture-recapture on marked or uniquely identifiable individuals. However, many species are difficult to sight, and cannot be easily marked or recaptured. Some of these species produce...
