Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The CTD was calibrated according to the Sea-Bird user manual. Logical_Consistency_Report: No formal logical accuracy tests were conducted. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the metadata for each part of this data release carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. The horizontal accuracy is based on ship’s position using the navigations system; Global Navigation Satellite System (GNSS) called CNAV with an accuracy of 1 m. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: A formal accuracy assessment of the vertical positional information in the data set has not been conducted. Depth was determined using a SeaBird CTD digiquartz pressure sensor with a stated accuracy of 0.015 percent. Lineage: Process_Step: Process_Description: Conductivity, salinity, and depth (CTD) data were collected with a SeaBird SBE-9 CTD Profile. Data were accumulated into .cnv tab-delimited ASCII text files. Data collected when instruments were out of the water were removed during post-processing. Files are named with a convention that uses a multi-element alphanumeric code delimited by dashes. The first element of this dataset consists of the instrument deployed CTD followed by the number indicating the cast and then the abbreviation for the research vessel (FK Falkor). The second element is the year of the field activity; the third element the cruise number of the vessel.
