Hydrographic and current time series data from inner Tempelfjorden during 29 January 2016 to 23 June 2017 at 78°26.606’ N; 017°21.269’ E, and 52 m depth. The mooring was deployed by the University Centre in Svalbard (UNIS) in collaboration with the Scottish Association for Marine Science (SAMS) as part of the project CRIOS to monitor any influence of water temperature on the tidewater glacier Tunabreen. It was equipped with one Aanderaa Instruments SeaGuard recoding current meter (RCM) with auxiliary CTD sensors close to the bottom. Additionally, three SBE 37 MicroCAT CTDs were distributed within 10 m above the RCM. For further details of the mooring and data, see Skogseth et al. (2019).
