Abstract:
Three sub-ice-shelf moorings were deployed on Fimbulisen by the Norwegian Polar Institute in December 2009 and have been maintained either each year or every two years. The data consist of temperature, pressure and velocity observations between 05.12.2009 and 31.12.2021 at three mooring sites. All three moorings are hanging below the ice shelf and each is equipped with an upper Aanderaa RCM9 close to the ice base and a lower one close to the bottom. Exact locations and depths are given in each data file.
Temperature data from all upper instruments are not included yet, but will be made available around June 2024.
Quality
The raw data have been processed and quality controlled. All velocities have been corrected for magnetic declination. Due to instrument failures, there are some gaps in the data, and due to sensor drifts, most salinity data had to be discarded.
Versions
Version 1 (03.07.2023): First upload of data. Version 1.1 (11.10.2023): An error in the time vector has been fixed. The time is now given in days since 1.1.1950 ( this was wrongly 1.1.1050 in v1.0). Version 2 (22.01.2024): Temperature, velocity, and pressure have been added until 31.12.2021 for M1_lower and M3_lower.
