This data set contains calculated organic matter decomposition rates from created and natural brackish marshes in Plaquemines parish, Louisiana near the West Pointe A La Hache siphon. One litter bag transect was deployed at six sites in May 2018, May 2019, and May 2021. Each litter bag transect was comprised of five plots at 1, 10, 25, 50, & 100 m from the marsh edge. Each of the five plots contained five litter bags with 25 grams of dried Spartina alterniflora per bag. Bags were deployed for two months.

This NCEI Accession consists of discrete measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), pH, dissolved oxygen, water temperature, salinity sampled in the National Park Service coastal sites along the Gulf Region and East Coast of the United States from 2024-07-02 to 2024-09-16.

This NCEI Accession consists of dissolved inorganic carbon (DIC), partial pressure of CO2 (pCO2), chlorofluorocarbons (CFC-12), sulfur hexafluoride (SF6), nutrients, dissolved oxygen, temperature, salinity and other measurements collected from discrete samples and profile observations during the CCGS Cartier Fisheries and Oceans Canada Atlantic Zone Offshore Monitoring Program (AZOMP) cruise (EXPOCODE 18QL20230524) in the North Atlantic Ocean and Labrador Sea from 2023-05-24 to 2023-06-12.

The data presented were collected during the Transarctica cruise of the vessel Le Commandant Charcot from Nome to Longyearbyen. A CTD probe, 16 data points per second and a ship-owned Ferry Box for atmospheric data, 1 data point per minute were recorded. This dataset is U.S. State Department MSR U2024-004 as part of the World Data Services for Oceanography. Cruise report is in PDF. Data are XLS format.

A topographic and bathymetric survey of the West Fork River near the West Fork Hoquiam River Dam was completed by Parametrix using conventional and GPS surveying equipment. The purpose of this survey was to develop pre-design engineering documents for dam removal. The survey was conducted using field traverse as per Washington Administrative Code (WAC) 332-130-090, Part C. Relative accuracy exceeds one foot in ten thousand. The resulting data and map of this work represents conditions and features existing at the time of this survey in April 2023.

This dataset includes surface underway chemical, meteorological and physical data collected from Autonomous Surface Vehicle (ASV) Saildrone 1038 (EXPOCODE 316420220616) in the Indian Ocean, Southern Ocean from 2022-06-16 to 2022-07-26.

This data package includes the benthic, urchin, and fish observation data collected for coral reef carbonate budget assessments by the Ecosystem Sciences Division (ESD) of NOAA's Pacific Island Fisheries Science Center (PIFSC) at fixed sites across American Samoa in 2023. These data were collected as part of a three-year methods development and pilot project funded by the NOAA Coral Reef Conservation Program (CRCP) in order to establish a standardized carbonate budget methodology for the National Coral Reef Monitoring Program (NCRMP) in the U.S. Pacific Islands.

From fall 2021 through summer 2023, NOAA and research partners conducted a field study (SPLASH - the Study of Precipitation, the Lower Atmosphere and Surface for Hydrometeorology). This field study established a state-of-the-art observing network in the East River watershed of the Colorado mountains with a goal of advancing weather and water prediction capabilities in areas with complex terrain. The ultimate goal of this project is improved prediction of weather and water in the Colorado mountains and beyond to inform societal preparedness and response.

This dataset contains bulk tissue carbon (delta-13C) and nitrogen (delta-15N) stable isotope values from sediment samples, marsh primary producers, marsh invertebrates, and marsh vertebrates collected at two created and four natural marsh sites in Plaquemines Parish, Louisiana near Lake Hermitage, West Point a la Hache, and Bay Batiste in May 2018. The data set also contains site location, species composition (determined to the lowest taxonomic level), body size, and elemental concentration information. Data are in spreadsheet format.

This dataset represents a “before and after” sediment sampling effort from Faga’alu Bay and watershed, American Samoa, to evaluate the effectiveness of best management practices at a quarry site. A suite of organic and inorganic parameters was quantified at twelve randomly selected and one targeted marine sites and four targeted stream site in 2014, including: polycyclic aromatic hydrocarbons (PAHs), pesticides, polychlorinated biphenyls (PCBs), trace elements, carbon, Clostridium perfringens abundance, and sediment grain size.
