Abstract:
Ocean microstructure profiles from a physical oceanography cruise in July-August 2022, in the Nansen and Amundsen Basin on R/V Kronprins Haakon, KH2022710. The data set includes 115 profiles of 1-decibar vertically averaged dissipation rate of turbulent kinetic energy, in situ temperature (ITS-90 scale) and salinity (practical salinity scale).
Quality
Profiles are collected using Sea and Sun Technology vertical microstructure profiler (MSS90L). The first 52 profiles are made with MSS053, the next ones with MSS046. The MSS90L is loosely tethered and is deployed using a winch, electric on board and maunal on the sea ice. Dissipation rate is measured using two airfoil shear probes. Profiles are averages from the two shear probes. The temperature and salinity profiles are measured from the SBE sensors on the same instrument. MSS90L has an unpumped CTD system. Careful corrections for temperature/conductivity sensor time lag and thermal lag were made. Temperature and salinity were corrected after comparison with the ship CTD. An offset of -0.05 is applied for profiles 13:52 and of +0.06 for profiles 53:115. Only downcasts from MSS90L are processed using the Sea and Sun technology routines. Resulting profiles are quality controlled, but still require caution from the user. More details are provided in the cruise report.
