Dataset Overview | National Centers for Environmental Information (NCEI)

Water temperature, acoustic travel time, pressure, and currents taken by current and pressure recording inverted echo sounders at four moorings in the north Atlantic ocean near Hydrostation S southeast of Bermuda from 2016-06-13 to 2017-06-29 (NCEI Accession 0191566)

Preview graphic

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.
