Low resolution real-time physical trajectory profile data from glider comet deployed by Helmholtz-Zentrum Hereon in the Mid-Atlantic Bight from 2021-09-07 to 2021-09-14 (NCEI Accession 0246946)

This dataset includes low resolution real-time physical trajectory profile data from glider comet deployed by Helmholtz-Zentrum Hereon in the Mid-Atlantic Bight from 2021-09-07 to 2021-09-14 for the NOAA Hurricane Glider and Sustained Underwater Glider Observations for Improving Atlantic Tropical Cyclone Intensity Forecast 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: This project supports the deployment and realtime data delivery of autonomous underwater gliders in the coastal ocean to better resolve and understand essential ocean features and processes that contribute to hurricane intensification or weakening prior to making landfall. Glider Comet is being deployed within the highly stratified Mid Atlantic Bight during the 2021 hurricane season with the goal of sampling ocean mixing during summer tropical cyclones or fall transition storms using an integrated Rockland Scientific, Inc Microstructure Profiler. Real-time data will support ongoing NOAA/NWS operational ocean modeling during hurricanes, while post-storm analysis will improve our understanding of ocean mixing processes.
