Alaska compendium of ocean profile data [ACOD]: Archival CTD and nutrient hydrography from NOAA's EcoFOCI, EMA, and predecessor programs

This oceanographic data product represents a multi-decade collection of
shipboard hydrography in Alaska waters, sampled by select programs of the
US National Oceanic and Atmospheric Administration (NOAA).  Data
types include basic physical (temperature and salinity) and chemical
(dissolved nutrient) properties collected as profiles from oceanographic
research vessels.  The geographic extent includes coastal and
offshore areas of the Gulf of Alaska, Bering Sea, and the Chukchi
Sea.  Temporal coverage is 1974-2021 (temperature and salinity)
or 2001-2021 (nutrient data).  Data in this product were
collected under programs associated with the NOAA Pacific Marine
Environmental Laboratory (PMEL) and Alaska Fisheries Science Center
(AFSC).  Three major data collection efforts are represented: (1)
the Ecosystems and Fisheries-Oceanography Coordinated Investigations
(EcoFOCI) program (PMEL and AFSC); (2) the Ecosystem Monitoring and
Assessment program led by AFSC and supported by EcoFOCI; and (3)
historical data collected between the founding of PMEL in 1973 and the
beginning of EcoFOCI in 1984.  Data were pooled across cruises
and years into a concatenated, single-point-of-access product, with
additional quality control applied to cruise records, profile data, and
nutrient data.  Simple derived quantities and indexing are
included for ease of use.  The data product is fully described in
Mordy et al. (2025, "A compendium of temperature and salinity
profiles and discrete nutrients from selected NOAA programs in
Alaska," Scientific Data).
