This data set is part of a larger set of data called the Multibeam Bathymetry Database (MBBDB) where other similar data can be found

Passive acoustic monitoring of Gulf of Maine waters is a critical aspect of understanding long term changes in North Atlantic right whale (NARW) presence and distribution within this region. An improved understanding of the presence of this species is needed in order to better monitor changes in distribution patterns and occurrence of this endangered species as well as to help understand where the risk of entanglement in fishing gear and ship strike may occur. These raw passive acoustic data will help develop mitigation strategies required by the U.S.

A series of synthesized sounds were played back from multiple locations around and within a grid of four DIFAR sonobuoys. Four type 53F DIFAR sonobuoys with attached SPOT GPS devices were deployed in a square with ~1nmi (2km) between each sonobuoy. Sound sources include periodic deployment of weighted light bulbs (producing an impulsive sound when the bulb implodes at depth) and synthetic tonal sounds broadcast through an underwater speaker. A time-synchronized multi-channel recording was made of the sounds received on the four sonobuoys.

The Space Environment Monitor (SEM) instrument onboard the NOAA POES satellite series and MetOp satellite series measures the flux of energetic ions and electrons at the altitude of the satellite. This data is used to detect and monitor space weather activity that may disrupt radio communications and/or the proper operation of satellite systems. The NOAA Space Weather Prediction Center (SWPC) processes the particle counts received from SEM instruments and uses the data to monitor solar activity and the state of the Earth's near space environment.

Within the NOAA National Ocean Service (NOS), the NOAA National Geodetic Survey (NGS) has a federal mandate to provide accurate positioning, including heights, to all federal non-military mapping activities in the USA. In 2007, the NGS embarked on the Gravity for the Redefinition of the American Vertical Datum (GRAV-D) Project, one of the most ambitious projects in the history of the agency. The gravity-based vertical datum resulting from this project is accurate at the 2 cm level where possible for much of the country.

This dataset includes the discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, ammonia, water temperature, salinity, dissolved oxygen and nutrients during the R/V F. G. Walton Smith cruise WS22141 (EXPOCODE 33WA20220521) in the Southeast U.S. Shelf, Gulf of Mexico from 2022-05-21 to 2022-05-27. Near-shore estuarine and coastal regions are where most recreational fishing and tourism occur, yet they are vastly under-sampled. Their susceptibility to OA is not well understood due to their high biogeochemical variability.

The World Ocean Database (WOD) is the World's largest publicly available uniform format quality controlled ocean profile dataset. Ocean profile data are sets of measurements of an ocean variable at a single geographic location within a short (minutes to hours) temporal period in some portion of the water column from the surface to the bottom. To be considered a profile for the WOD, there must be more than a single depth/variable pair. Multiple profiles at the same location from the same set of instruments is an oceanographic cast.

This dataset includes measured sediment characteristics and vertical accretion rates of backbarrier marshes along the Georgia Bight. Data include bulk density (g/cm^3), water content (%), organic content (%), Pb-210 (Bq/kg), Cs-137 (Bq/kg), and calculated rates of vertical accretion (mm/yr) as measured from sediment cores collected during December 2017. Data are provided as CSV files.

This dataset contains oceanographic data collected from NOAA Ship OKEANOS EXPLORER in the North Pacific Ocean from 2023-11-30 to 2023-12-08. Data acquisition from shipboard sensors includes navigational and meteorological data.

This data set contains landscape mosaic images, created as a product for the NOAA Coral Reef Conservation Program’s (CRCP) National Coral Reef Monitoring Program (NCRMP). Orthorectified mosaic images of six reef plots were captured of Cheeca Rocks reef in the Florida Keys. Each reef plot is made up of a 10m x 10m transect area (100 m2). Landscape mosaics are a composite of many underwater images stitched together. These mosaics have the clarity and pixel size of the individual pictures but collectively produce a “landscape view” of the coral reef community within each transect.
