Conductivity Temperature and Depth (CTD) Data from the 2025K19 Cruise with KBV 181, 19 - 22 May 2025

SWERVE Data Package: 2025K19 KBV 181 Cruise Information:-------------------Cruise Name: 2025K19Purpose of the Cruise: What are the environmental risks associated with seabed mining for rare earth elements in the Baltic Sea? Quantifying impacts on benthic biodiversity and ecosystem processes.Ship: KBV 181Ship Code: 77K9Cruise Number: 19Cruise Dates: 2025-05-19 to 2025-05-22Geographical Area: Bothnian BayPI: Francisco Nascimento, Stockholm UniversityAwards: Grant to research infrastructure of national interest 2023-00159, Swedish Research Council Data Package Contents:----------------------This package contains 12 CTD casts collected during the cruise. Each cast has 6 files - 4 raw files (.bl, .hdr, .hex, .xmlcon) and 2 processed files (.asc, .cnv). File Naming Convention:All files follow the SWERVE naming convention:[INSTRUMENT]_[SERIAL NUMBER]_[YYYYMMDD]_[HHMM]_[SHIPCODE]_[CRUISE]_[STATION] Where:- INSTRUMENT: CTD instrument type (e.g., SBE09)- SERIAL NUMBER: CTD instrument serial number- YYYYMMDD: Date of cast- HHMM: Time of cast- SHIPCODE: Ship code- CRUISE: Cruise number- STATION: Station number Folders follow the same convention but without time and station number. Measured Variables:-------------------The following variables are included in the processed data files: prDM: Pressure, Digiquartz [db]c0S/m: Conductivity [S/m]t090C: Temperature [ITS-90, deg C]par/sat/log: PAR/Logarithmic, Satlantic [umol photons/m^2/sec]spar/sat/lin: SPAR/Linear, Satlantic [umol photons/m^2/sec]dz/dtM: Descent Rate [m/s]sbeox0ML/L: Oxygen, SBE 43 [ml/l] ***PLEASE OBSERVE THAT OXYGEN DATA ARE CORRUPT, THE SENSOR WAS NOT WORKING DURING THIS CRUISE***density00: Density [density, kg/m^3]sal00: Salinity, Practical [PSU]depFM: Depth [fresh water, m], lat = 64.416nbin: number of scans per bin
