Dataset Information

HDF5_OBJ_FULLPATH: H5_GLOBAL
title: OMG Bathymetry SBES Level 2 Data
summary: This file contains Singlebeam Echo Sounder System (SBES) survey measurements of sea floor depth along a ship track. The SBES system records only a single depth, directly below each ship location.

history: Transformed input product 11-Feb-2016all_filtered_100.csv into NetCDF format. This product was updated on August 1, 2019 to be consistent with the improved precision update of the lat and lon variables in the other SBES products. The lat and lon values in this product remain unchanged after the update.
source: Bathymetry data collected with a 1 Kw singlebeam sonar with an integrated GPS that has a maximum 2100 feet depth range.
platform: R/V Ault Vessel
instrument: Multiple Singlebeam Echo Sounder Systems (SBES)
processing_level: L2
comment: This data was collected during the 2015 survey of the Greenland's Western coastline.
