Abstract:
A set of inter calibrated salinity in-depth profiles in Hornsund Fjord.We used all of our CTD sensors (Valeport: 1 CTD; RBR: 3 CTD, 2TD, 6 T; SeaBird 1CT; SAIV A/S: 1 CTD), at the same time in a stable position at stable depths for 24 hours measurement. SAIV A/S conductivity data was different from the rest. Because for CTD in-depth profile Valeport and SAIV A/S were used we made comparable CTD in-depths profiles for these two CTD sensors. Based on comparison plots for temperature and conductivity from the same depths for all comparable in-depth profiles for these two sensors we add linear correction for temperature and conductivity data from SAIV A/S. After losing SAIV A/S sensor we made the same procedure for the new. Depth (UNESCO Technical Papers in Marine Science No. 44), salinity (UNESCO 1983), density (Millero and Poisson 1981, UNESCO 1981) were calculated based on a commonly used formula from pressure, temperature, and conductivity after data inter-calibration.
