Hydrographic and current time series data from inside of the entrance of Isfjorden at the southern side during 08 Sep 2019 to 08 Jun 2020 at 78°07.517’ N; 014°25.157’ E, and 187 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 inflow from the Isfjorden Mouth to Isfjorden proper and the hydrographic differences between outside and inside of the mouth area. It was equipped with two Aanderaa Instruments recording current meters (RCMs) with auxiliary CTD sensors covering the upper and the bottom layer. Additionally, three SBE 37 MicroCAT CTDs and one VEMCO mini temperature logger were evenly distributed over the water column.
