This dataset consists of measurements of dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, temperature, salinity, dissolved oxygen, nutrients and ammonium collected from the third dedicated West Coast Ocean Acidification cruises (EXPOCODEs: 317W20130803 and 32P020130821, Cruise IDs: WCOA2013), which took place aboard NOAA Ship Fairweather from 2013-08-03 to 2013-08-10, and aboard the R/V Point Sur from 2013-08-21 to 2013-08-29. Seventy-six stations were occupied from northern Washington to California along ten transect lines.

The North Pacific right whale (NPRW) was heavily hunted between the 17th and the 20th centuries. Protection was supposedly afforded by international treaties in the 1930s and 1940s, but the illegal capture of hundreds of individuals by the Soviet Union, primarily in the 1960s drastically impacted the recovery of the species. Currently, only a small remnant of this population (estimated at approximately 30 individuals) inhabits the southeastern Bering Sea (SEBS).

The National Marine Fisheries Service (NMFS) has conducted aerial counts of Cook Inlet beluga whales (Delphinapterus leucas) from 1993 to 2022 (excluding 2013). Nearly all counts were conducted during the month of June. The routine nature of these counts and the consistency in research protocol lend themselves to inter-annual trend analyses. Beginning in 2005, an aerial survey was added during the month of August to document calving groups within the upper Inlet (north of East and West Foreland).

Aerial photographic surveys for bowhead whales were conducted near Point Barrow, Alaska, from 19 April to 6 June in 2011. Approximately 4,594 photographs containing 6,801 bowhead whale images were obtained (not accounting for resightings). The 2011 field season was very successful: we flew 36 out of 49 available days and conducted 49 flights in that time; we were grounded due to weather on 13 days. The longest period of time that we were grounded due to weather (low ceilings/fog) was three days.

Basic hydrographic properties (T, S, P, calculated density, chlorophyll a fluorescence, and dissolved O2) collected via CTD profile in the 2004, summertime Gulf of California. Continuous CTD data binned to 1 meter.

Mooring data collected with SeaBird MicroCAT SBE37s, Aanderaa RCMs, and Submerged Autonomous Launch Platform (SALP) by the Woods Hole Oceanographic Institution in 2007-2009 during the Impact of Irminger Rings on Deep Convection in the Labrador Sea experiment (IRINGS) project.

This dataset contains output from a study designed to evaluate the impacts of ocean acidification on the food web of Puget Sound, a large estuary in the northwestern USA. An Ecopath with Ecosim model of Puget Sound was forced with scenarios designed to mimic some of the biological consequences of ocean acidification, specifically the decline in the productivity of functional groups that contain mostly calcifiers. Other functional groups in the model were allowed to respond to the scenarios in a dynamic way through indirect effects.

Fish age validation with bomb-produced radiocarbon (14C) requires a known-age Delta14C reference chronology spanning the era of a marine increase in bomb-produced 14C (1950s to 1960s). Concordance between otolith Delta14C in a validation sample and the reference chronology indicates accurate test ages.

As part of an inter-agency agreement between the National Marine Mammal Laboratory and the Bureau of Ocean Energy Management, aerial surveys of the North Aleutian Basin and southeastern Bering Sea were conducted from 24 July to 28 August 2008 and 14 July to 25 August 2009. Both surveys were conducted from an Aerocommander 690A. In 2008, the survey design consisted of broadscale transects covering the waters from Bristol Bay west to the Pribilof Islands.

This dataset contains the results of a laboratory experiment study to understand the effect of ocean acidification on eggs and larvae of northern rock sole, Lepidopsetta polyxystra. The Bering Sea and Gulf of Alaska support a number of commercially important flatfish fisheries. These high latitude ecosystems are predicted to be most immediately impacted by ongoing ocean acidification but the range of responses by commercial fishery species has yet to be fully explored.
