Hydrographic and current time series data from outside the northern side of the Isfjorden Mouth during 5 October 2017 to 24 August 2018 at 78°10.911’ N; 013°23.350’ E, and 242 m depth. The mooring was deployed by the University Centre in Svalbard (UNIS) as a part of the AGF course “Polar Ocean Climate” to monitor outflow from Isfjorden and the hydrographic differences between the northern and southern part of the mouth. It was equipped with two Aanderaa Instruments recoding current meters (RCMs) with auxiliary CTD sensors covering the upper and the bottom layer. Additionally, three SBE 37 MicroCAT CTDs and three VEMCO mini temperature loggers were evenly distributed over the water column. For further details of the mooring and data, see Skogseth et al. (2019).
