TY - A2 - Cooperative Institute for the North Atlantic Region AB - The NOAA Distributed Biological Observatory (DBO)/Ecosystems & Fisheries Oceanography Coordinated Investigations (EcoFOCI) joint cruise with the Arctic Marine Biodiversity Observation Network (AMBON) and the Chukchi Ecosystem Observatory (CEO) programs included hydrographic and biological surveys consisting of conductivity-temperature-depth (CTD) rosette sampling, zooplankton and larval fish net tows, Van Veen grabs and HAPS coring for sediment sampling, and beam trawling for epibenthic collections. The cruise conducted recoveries and deployments of year-round marine mammal listening moorings and oceanographic moorings (Figure 1.1, 1.2). The goal of the cruise was to evaluate ecosystem status and change in the northern Bering and Chukchi Seas.

Proceedings of the 2024 Ageing Workshop for Atlantic Spiny Dogfish, Squalus acanthias

Passerotti, Michelle S. (editor) ;

Philipp, Madison (editor)

2025 | NOAA technical memorandum NMFS-NE ; 339 | pdf

Spiny dogfish in the western north Atlantic (WNA) have a long and storied history within the scope of fisheries management. Once abundant, the WNA stock has more recently been overexploited. While not currently assessed as overfished, uncertainties surrounding biology, growth, and age estimation have prevented confident projections for biomass and ...

The 2024 Spiny Dogfish Ageing Workshop was convened 22 to 23 January 2024 in Raleigh, North Carolina, bringing together experts from around the world to share knowledge and best practices for age estimation in this hard-to-age species towards a goal of consistent age determination for the WNA stock in the future.
