Abstract:
The fixed layer ocean buoy consists of four conductivity and temperature sensors (RBR duo CT), one conductivity sensor and temperature and depth (pressure) sensors (RBR concerto CTD). Ground devices include GPS, Iridium communication, SD card, power supply and foam float. The ocean sensor extends 200 meters below the ice, with five layers at 10 meters, 20 meters, 50 meters, 100 meters and 200 meters deep. CTD is located at 100m layer, and the other four layers are CT. Among them, the CTD equipment has a fault and can only read the temperature elements. Fixed layer marine buoys are deployed at L1 site, 85 º 00'43 ''N, 132 º 45'35'' E, and the recovery position is 83 ° 74'38''N, 19 ° 45'96''E.

Comment:
This is the temperature and salinity data from October 5, 2019 to May 4, 2020. Because the only CTD is broken, we cannot calculate the deflection angle of the cable under water. We can only use the position of the instrument placed on the cable in advance as a depth reference.
