This dataset includes low resolution real-time physical trajectory profile data from glider bios_anna2 deployed by Bermuda Institute of Ocean Sciences (BIOS) in the Northwest Atlantic Ocean from 2021-07-26 to 2021-08-15 for the MAGIC: Mid Atlantic Glider Initiative and Collaboration 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 Bermuda Institute of Ocean Sciences MAGIC Lab was inaugurated in 2014 through generous support from the Kerr Fund, Simons Foundation International, Vetlesen Foundation and FIL Foundation. Gliders are small, free-swimming, unmanned vehicles that use changes in buoyancy to move vertically and horizontally through the water column in a saw-tooth pattern. They are deployed for days to several months and gather detailed information about the physical, chemical and biological processes of the world's oceans. The Slocum glider was designed and built by Teledyne Webb Research Corporation, Falmouth, MA, USA. This dataset contains observational sub-surface profile data of the water-column.
