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.

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.

Observations were conducted from June 1999 to July 2001 to study the shallow and deep current variability in the southwest Japan/East Sea. Data were collected during the field experiment with a two-dimensional array of pressure-gauge equipped inverted echo sounders (PIES) and deep recording current meters (RCM). Hourly measurements of vertical acoustic travel time, pressure, temperature and horizontal currents are provided. Additional processing has been done to provide data sets which can easily be used together as a coherent array. The travel time records have been projected on to a common depth level, low-pass filtered, and subsampled to twice daily. The low-pass filtered, subsampled pressures have been adjusted to a common, deep geopotential surface. Small gaps in the current measurements have been replaced by fitted-spline interpolated values.

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 water conductivity and temperature casts collected by CTD from the research vessel Heron. Voltage profiles were measured by an optical backscatter probe deployed from research vessel Heron. ADCP instrument was deployed 30 m above the seabed, suspended from a fixed vessel (research vessel Strickland). The research vessel Strickland was moored (using 4 anchors) above the central submarine channel downstream of the Squamish delta. File Beamave_EA.txt contains the echo intensity averaged between four ADCP beams in counts. Echo intensity was used to derive the concentration of suspended sediment from 30 m to 60 m water depth, using an acoustic inversion method and physical samples for calibration. File vmag.txt contains the magnitude of velocity in m/s. These data were used to obtain the turbidity current measured on 15th June 2015. Data are in ASCII format.

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.

The sound velocity and other data in this accession has been processed by NODC from a tape submitted by the originator containing Inverted Echo Sounder data from the R/V Endeavor cruise 205, October 1989. It also contains data previously sent to NODC for the Seasonal Equatorial Atlantic (SEQUAL) project for sites Sal and Sol. These data are in NODC format for pressure gauge data (F017) and the format described in the documentation. The file Sal represents observations from several deployments (overlap of instruments) therefore there are duplicates in the data. These data have been released by Dr. Eli Katz from Lamont-Doherty Geological Observatory. CTD data was also sent and can be found under track numbers TV5152-TV5154. Data has been re-processed and re-submitted on March 24, 1991. A01402 W18760 Data has been processed by NODC to the NODC standard High-Resolution CTD/STD (F022) format. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.

The dataset is an archive of CTD data obtained from a towed undulating platform (Acrobat) in the region near the mouth of Long Island Sound. The observations were made with a Towed Oceanographic Microstructure and Auxiliary Sensors Instrument (TOMASI) manufactured by Rockland Scientific. The TOMASI was carried aboard a towed undulating vehicle, an Acrobat manufactured by SeaSciences. The Acrobat was towed behind the ship (cable payout is given within the header portion of the data files) and undulated between approximately 2 m below the surface to approximately 5 m above the bottom (or to a maximum depth of about 40 m). The dataset consists of 61 files each containing time series of longitude, latitude, pressure, temperature, conductivity, salinity, and sigma-t.
