This data set contains vertical acoustic travel time, bottom pressure and temperature, as well as near-bottom current and temperature taken by four current and pressure recording inverted echo sounders, CPIES, near Hydrostation S in the north Atlantic southeast of Bermuda from 2016-06-13 to 2017-06-29. The hourly time series are the highest quality versions of the data after the least amount of processing. The collection and processing of the data are described in the report provided. Data are in NetCDF.

Acoustic roundtrip travel time, hydrostatic pressure, and ocean velocity recorded by Current- and Pressure-recording Inverted Echo Sounder (CPIES) instruments at five mooring locations in the Indian Ocean as part of the Agulhas System Climate Array (ASCA) project. Data are in NetCDF.

This dataset contains daily measurements of bottom pressure and round-trip acoustic travel time from three pressure-equipped inverted echo sounder (PIES) moorings deployed in the southwest South Atlantic Ocean from 2016-10-24 to 2019-06-26 as part of the Southwest Atlantic Meridional Overturning Circulation (SAM) Project. The SAM Project is funded by the NOAA Ocean Observing and Monitoring Division and by the NOAA Atlantic Oceanographic and Meteorological Laboratory. Both the processed daily records and the raw hourly measurements are included. The three PIES in this dataset were deployed at the following nominal locations - Site A: 51deg 30min W, 34deg 30min S Site C: 47deg 30min W, 34deg 30min S Site D: 44deg 30min W, 34deg 30min S The PIES mooring at Site D was recovered in 2018; the PIES moorings at Sites A and C were recovered in 2019. The metadata on the nominal locations and other details of the observing array are the same as for accession 0125596. Data from previous deployments are contained in accessions 0125596 and 0175745. Data are in ASCII format.

Acoustic roundtrip travel time, pressure, ocean velocity, and temperature recorded by Current- and Pressure-recording Inverted Echo Sounders (CPIES) instruments at five mooring locations as part of the Agulhas Current Time-series experiment (ACT).

Temperature profile and sound velocity data were collected using inverted echo sounder (IES) in the North Atlantic Ocean from March 19, 1973 to July 3, 1973. Data were submitted by University of Rhode Island; Graduate School of Oceanography as part of the International Decade of Ocean Exploration / Mid-Ocean Dynamics Experiment (IDOE/MODE) project.

This dataset contains round trip acoustic travel time and ambient bottom pressure from bottom-mounted instruments spaced zonally along 34.5S in the SW Atlantic east of Uruguay, July 2011 to October 2016. The data were collected for the Southwest Atlantic meridional overturning circulation ("SAM") project by the NOAA-Atlantic Oceanographic and Meteorological Laboratory. Both the processed/quality-controlled and the raw data files are available. Format is text.

This data set contains Current and Pressure recording Inverted Echo Sounder (CPIES) measurements collected during the Kuroshio Extension System Study (KESS) under the sponsorship of the National Science Foundation. The measurements were taken between April 2004 and June 2006. Data are from 46 sites. The measured quantities include bottom pressure, vertical acoustic round-trip travel time and near-bottom currents.

This portion of the data release presents acoustic backscatter data from the San Miguel Passage, in the Channel Islands, California. The data were collected in August 2007 by the U.S. Geological Survey, Pacific Coastal and Marine Science Center (USGS, PCMSC) using a 234.5 kHz SEA (AP) Ltd. SWATHplus-M phase-differencing sidescan sonar mounted on the NOAA, Channel Islands National Marine Sanctuary R/V Shearwater as part of the research cruise S-2-07-SC. Data were collected in water depths up to 89 meters. The San Miguel Passage is within the Channel Islands National Marine Sanctuary and is the body of water between the two western-most islands of the chain - Santa Rosa and San Miguel Islands. The data were processed at the USGS, PCMSC to create a 2-meter resolution TIFF raster, presented here.
