Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-02-21T00:00:00Z
On October 5-6, 2022, a combination of Acoustic Doppler Current Profiler (ADCP) and Global Navigation Satellite System (GNSS) surveying was used to collect bathymetric data of the Lummi Sea Pond near Bellingham, WA. Distributed XYZ points were interpolated to create a continuous bathymetric map of the sea pond. The final product is two-meter raster in NAD88 (2011) UTM 10N coordinates, with elevations referenced to NAVD88 (GEOID18a). Details of the process used to construct the surface are provided in this metadata. Supporting datasets included in the zip file include raw ADCP data, ADCP bathymetry data in CSV format, and GNSS data in CSV format.
