Title: A huge mesoscale eddy observed in the Arctic Ocean

Abstract: Mesoscale ocean eddies are energetic vortex structures that transport the physical properties of water. The water trapped in eddies keeps its properties and may travel inside an eddy up to thousands of kilometres from its origin. The Arctic Ocean is known to be inhabited with mesoscale eddies commonly detected in depths from 200 m to 1200 m. Due to their high energetics and the ability to transfer momentum, heat and salt for long distances, the eddies may considerably affect the vertical structure of the water column in the AO.
This study investigates an eddy-like structure detected at one of the NABOS mooring stations located at the continental slope in the Laptev Sea (2013-2015). What is interesting about this eddy is that it persisted over the mooring station for almost 50 days. The CTD (conductivity-temperature-depth), current measurements from the Acoustic Doppler Current Profiler in the upper ocean (30-90 m) and from the McLane Moored Profiler in the lower ocean (100-700 m) are examined. The results of this case-study will show the specific features of the eddy detected in the Eurasian Basin of the AO and to contribute to the in-depth understanding of the Arctic eddies behaviour.
