Episodic warming of near-bottom waters under the Arctic sea ice on the central Laptev Sea shelf.

Abstract

A total of four moorings ("1893", "Taymyr", "Kotelny", "Vilkitsky") was deployed in September 2013 during the Transdrift XXI - expedition and recovered in September 2014 during Transdrift XXII aboard the Viktor Buinitsky. The expeditions were carried out in the framework of the German-Russian "Laptev Sea Systems" partnership, and within the BMBF-funded "Transdrift"-project. The moorings were designed to collect information on the general shelf circulation, to study ice-ocean-atmosphere processes, and to understand the role of the Lena River on the oceanography of the Laptev Sea.
