Glider observations of northwestern inflows of Atlantic water to the North Sea.

University of East Anglia (UEA) and Marine Scotland Science deployed an autonomous profiling ocean glider (Seaglider 502) at the Joint North Sea Information System (JONSIS) hydrographic section (2.23°W to 0° at 59.28°N). The glider repeatedly occupied the section between 12th October and 2nd December 2013, taking full-depth temperature, salinity, oxygen, chlorophyll and optical backscatter observations. Dive-average current observations were also collected. The glider was deployed by MRV Scotia and recovered by MPV Jura. The JONSIS section crosses the path of the Fair Isle Current and the East Shetland Atlantic Inflows, key routes by which Atlantic water enters the northern North Sea.
