Dataset Overview | National Centers for Environmental Information (NCEI)

Low resolution real-time physical trajectory profile data from glider sg263 deployed by University of Washington, Applied Physics Laboratory (APL) in the Coastal Waters of Washington/Oregon from 2024-11-26 to 2025-01-06 (NCEI Accession 0302050)

This dataset includes low resolution real-time physical trajectory profile data from glider sg263 deployed by University of Washington, Applied Physics Laboratory (APL) in the Coastal Waters of Washington/Oregon from 2024-11-26 to 2025-01-06 for the Washington Coast La Push Glider Line project.

The National Centers for Environmental Information (NCEI) received the data in this dataset from the Integrated Ocean Observing System (IOOS) National Glider Data Assembly Center (NGDAC). The IOOS NGDAC received the data in one or more netCDF files comprising an entire glider deployment. The data are measurements of physical oceanographic properties such as temperature, salinity, conductivity, and density. The IOOS NGDAC checked the files for compliance to their netCDF file convention, aggregated the files into a single netCDF file, and then submitted the file to NCEI for long-term preservation. Data files may be either low resolution real-time or full resolution. Full resolution files are designated as "delayed" in the netCDF file name.

The data producer provided this summary: The La Push glider line aims to extend the time series of sustained glider-based measurements off the Washington Coast that begun in 2003. Seaglider and SGX underwater gliders repeatedly occupy a single section that extends offshore from the continental slope to 47N, 127W. Gliders profile from the sea surface to 1000-m depth and back every 6 hours while traversing the line at a speed of roughly 20 km/day. The La Push line is sampled by a single glider, which is replaced as needed to maintain continuous occupation of the section.
