North Carolina State University
Coastal Glider Program


Description:

We will be deploying a coastal glider to measure shelf water temperature and salinity fields off the North Carolina coast. We utilize the Webb Research's Slocum Glider, which is an autonomous vehicle that can operate unattended for roughly a month-long period in the coastal ocean. Surveys of Temperature and Salinity fields are required to quantify the vertical structure of the coastal ocean mass field. The benefits of these measurements are spatially dense observations of shelf hydrography, a fundamental property of the physical state of the ocean. Structure of the mass field plays a defining role in cross-shelf exchange, vertical structure of the ocean boundary layers, and vertical exchange. Realistic models of coastal ocean circulation require knowledge of its structure and variability. While at sea our onshore team will monitor and direct glider trajectories using two-way communications. The communications permit near real-time delivery of observations and re-direction of mission/adaptative sampling. Given a forward horizontal speed of 0.25-0.35 m/s, the glider can cover 20-30 km per day, depending on environmental conditions.
