资源简介：
The Alaska Fisheries Science Center uses trawl-mounted conductivity, temperature, and depth devices (CTDs) (Sea-Bird Scientific SBE 19plus V2 SeaCAT Profiler CTD) to collect oceanographic data during bottom trawl surveys conducted aboard chartered commercial fishing vessels. Collecting CTD data in this manner minimizes sampling time and the need for specialized equipment, but it also contributes to dynamic errors in salinity profiles (e.g., salinity spikes) that are not corrected using ‘typical’ data processing methods. To improve dynamic error correction, we developed a data processing protocol that uses four methods to correct dynamic errors, where the best-performing method is selected for each CTD deployment based on qualitative visual inspection of processed profiles.
