As part of a multi-year effort to quantify the flux of CO2 between the ocean and atmosphere, the Ocean Climate Observation Program of the National Oceanic and Atmospheric Administration (NOAA) supports the deployment of underway CO2 systems on NOAA research ships and volunteer observing ships (VOS) in the Atlantic and Pacific Oceans. The CO2 group of NOAA's Pacific Marine Environmental Laboratory (PMEL) has been monitoring sea surface CO2 concentrations in the equatorial Pacific since 1982.

This is the full set of Southeast Florida Coral Reef Evaluation and Monitoring Project (SECREMP) raw data. This includes in situ surveys of benthic substrate coverage, stony coral abundance and condition, octocoral abundance and condition, Xestospongia muta abundance and condition, and hourly temperature records from each SECREMP site. Abstracts are provided for each dataset individually.

This dataset contains only the final cruise report or data collected aboard the research vessel Falkor during cruise FK180119 in the North Pacific Ocean from 2018-01-19 to 2018-02-07. Measurement data are archived separately in NCEI accession 0177752 and related datasets (see the Documentation section). This cruise is U.S. State Department MSR U2017-021 as part of the World Data Service for Oceanography.

This dataset consists of surface measurements of dissolved inorganic carbon (DIC), total alkalinity (TALK), temperature and salinity during the R/V Marion-Dufresne Ocean Indien Service d'Observations - 30 (OISO-30) cruise (EXPOCODE 35MV20200106) in the Indian Ocean from 2020-01-06 to 2020-02-01. The OISO program (Océan Indien Service d'Observations), initiated in 1998, collects measurements of pCO2 and associated parameters (T, S, DIC, TALK, nutrients, Chl-a, 13C) along the repeated lines of R.V.

Coral adult and juvenile coral colony demographic data described in this dataset are derived from the GIS analysis of benthic photomosaic imagery collected across the Mariana Archipelago in 2022 for a methods comparison with in situ diver data. Official National Coral Reef Monitoring Program (NCRMP) coral demographic data is archived separately under NCEI Accession 0298217. The source imagery was collected using a Structure from Motion (SfM) approach during in-water surveys conducted by divers.

The Northwest Fisheries Science Center's (NWFSC) Salmon Population Summary (SPS) database provides public access to demographic data compiled for ESA-listed salmonid populations as part of the NWFSC's technical recovery planning efforts. The database contains data collected by co-managers (WDFW, ODFW, IDFG, and Tribes) and compiled in cooperation with NWFSC staff for: spawning abundance, age structure of wild spawners, fraction of natural spawners that are of wild origin, and the reduction in spawning abundance due to harvest.

This dataset consists of surface measurements of dissolved inorganic carbon (DIC), total alkalinity (TALK), temperature and salinity during the R/V Marion-Dufresne Ocean Indien Service d'Observations - 31 (OISO-31) cruise (EXPOCODE 35MV20210113) in the Indian Ocean from 2021-01-14 to 2021-03-04. The OISO program (Océan Indien Service d'Observations), initiated in 1998, collects measurements of pCO2 and associated parameters (T, S, DIC, TALK, nutrients, Chl-a, 13C) along the repeated lines of R.V.

This dataset contains the trajectory profile data from glider ru26d from 2022-07-14 to 2022-07-26 to assess seawater pH and other oceanographic measurements including water temperature, salinity, optical properties (i.e., chlorophyll, CDOM, backscatter), and dissolved oxygen. The glider used for the automated observation includes an integrated deep rated version of the Ion Sensitive Field Effect Transistor (ISFET)-based pH sensor. This delayed mode, high-resolution post-processed dataset contains CTD, chlorophyll a, dissolved oxygen and pH data.

This dataset contains physical, chemical, and biological ocean parameters, as well as atmospheric parameters taken by CTD, Niskin bottles, and other instrumentation from research vessel Araon, cruise ARA10A,B, in the Bering and Chukchi Seas. The expedition was a part of an ongoing project on the Korea-Arctic Ocean Observing System (K-AOOS) Project of the Ministry of Oceans and Fisheries, Korea.

This project ensures that the existing data from previous fishery independent surveys can be combined with data collected under new methodology, ensuring preservation of long-time series reef fish datasets in the US Caribbean. Specifically, this archived dataset are the site level fish abundance and size observations collected simultaneously by one transect diver and a pair of stationary point count divers at survey sites in Puerto Rico and the U.S. Virgin Islands.
