Seaglider observations in Davis Strait; 2005-2014

The Davis Strait observing system was established in 2004 to advance understanding of the role of Arctic – sub-Arctic interactions in the climate system by collecting sustained measurements of physical, chemical and biological variability at one of the primary gateways that connect the Arctic and subpolar oceans. Efforts began as a collaboration between researchers at the University of Washington’s Applied Physics Laboratory and the Canadian Department of Fisheries and Ocean’s Bedford Institute of Oceanography, but has grown to include researchers from the Greenland Institute of Natural Resources, Greenland Climate Institute, Danish Technological University, University of Alberta and University of Colorado, Boulder. The project is a component of the NSF Arctic Observing and Atlantic Meridional Overturning Networks, and the international Arctic-Subarctic Ocean Flux (ASOF) program, Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP), Global Ocean Acidification Observing Network (GOA-ON), Arctic Monitoring Assessment Programme (AMAP) and OceanSITES system.
Seaglider observations of temperature and salinity extending from the surface to a maximum of 1000 meter (m) depth were collected in Davis Strait from 2005-2014. Seagliders made repeat transects across Davis Strait between waypoints near 66°45' North (N), 60°30' West (W) and 67°N, 56°30' W (though these waypoints and the pathway of the gliders between the waypoints varied). Acoustic navigation enabled year-round data collection.
This dataset contains 15 files, each of which contains Level 3 data from one Seaglider deployment in Davis Strait. Deployments lasted from 11 to 174 days and had a median duration of 83 days. Files contain several temperature and salinity products: data not interpolated or despiked; data despiked and interpolated to a common depth/time grid; and low-pass filtered data. Files also include quality control (QC) flags. Each file also contains depth-averaged current vectors from the Seaglider flight model and surface current vectors estimated from the Seaglider's drift track.
Data files are named as follows: sg<seaglider number>_DavisStrait_<deployment data in MmmYY format>_level3.nc
Level 2 files containing individual dive data are available by contacting the dataset creator.
