This dataset contains oceanographic data collected from NOAA Ship OKEANOS EXPLORER in the Gulf of Mexico from 2022-02-23 to 2022-03-03. Data acquisition from shipboard sensors includes navigational data, meteorological data (wind), and oceanographic data (sound velocity probe, thermosalinograph). Additional data include Profile Data (ASVP and CTD), event logs, images, ROV ancillary data, and specimen data.

This submission contains salinity-calibrated Conductivity Temperature Depth (CTD) data from the 2019 Ocean Observations Initiative (OOI) Irminger Sea 6 cruise (AR35-05). Data quality control methods have been used to assess performance of the CTD instrument. Resulting high-quality profiles were then used together with salinity bottle data analyzed at sea to create a post-cruise salinity-calibrated CTD product.

Water quality data was collected by the United States Army Corp of Engineers at numerous locations along the shore of Lake Ponchartrain and the Tangipahoa River in Louisiana from May to September 2020. The samples were collected repeatedly at 6 locations. The parameters collected include ammonia, phosphorus, chlorophyll, phycocyanin, microcystin, silica, water temperature, dissolved oxygen, dissolved oxygen percent saturation, depth, pH, total dissolved solids, total organic content, salinity, specific conductance, and plankton cell counts.

This submission contains salinity-calibrated Conductivity Temperature Depth (CTD) data from the 2018 Ocean Observations Initiative (OOI) Irminger Sea 5 cruise (AR30-03). Data quality control methods have been used to assess performance of the CTD instrument. Resulting high-quality profiles were then used together with salinity bottle data analyzed at sea to create a post-cruise salinity-calibrated CTD product.

This dataset contains salinity-calibrated Conductivity Temperature Depth (CTD) data from the 2020 Ocean Observations Initiative (OOI) Irminger Sea 7 and Overturning in the Subpolar North Atlantic Program – Greenland Deep Western Boundary Current (ONSAP GDWBC) cruise (AR46). Data quality control methods have been used to assess performance of the CTD instrument. Resulting high-quality profiles were then used together with salinity bottle data analyzed at sea to create a post-cruise salinity-calibrated CTD product.

In order to accurately assess the initial affects of bleaching events, and to assess coral condition during and after bleaching events, the Florida Keys BleachWatch program coordinates a large network of trained observers to provide regular reports of actual coral conditions on the reefs.

This dataset includes lakebed maps and associated geospatial data in Lake Superior, offshore the Wisconsin Bayfield Peninsula and the Apostle Islands National Lakeshore. Associated data include remotely sensed lakebed imagery (e.g., multibeam bathymetry, backscatter) and underwater videos. The dataset includes original data collections and modeled data. Original data collection spans the years 2020 to 2021, and lakebed models and derived maps were developed in 2022.

This data compilation includes the results of grain size analyses of core sediment collected by IODP during Expedition 323 in the Bering Sea. One dataset is included for each of the five sites investigated: Sites U1339, U1340, U1341, U1343, and U1344. The cruise occurred in Summer 2009, the analyses were carried out between 2010 and 2012. This compilation is the only sedimentologic resource curently available for the Bering Sea to cover a long period of Earth's recent climate history (about 5Ma to present) from different locations within the basin (Bering Slope and Bowers Ridge).

The Index to Marine and Lacustrine Geological Samples (IMLGS) product is being decommissioned. Archived IMLGS data will only be available via an archive request to [email protected]. The planned retirement date is May 5th, 2025.

PETROS is a worldwide data bank of major element chemical analyses of igneous rocks compiled for research and teaching purposes by Dr. Felix Mutschler and Staff at Eastern Washington University. PETROS version 6.1 includes 37,300 major element chemical analyses divided into 307 major groups representing geographic areas or petrologic provinces. The data are for 4,512 cores, grabs and dredges. Also included are 468 average igneous rock compositions calculated by various authors, a bibliography of information sources, and complete format/operating instructions for PETROS.
