cruise: KB2021620 time: 2021-08-26T06:52:51Z - 2021-08-26T09:15:14Z latitude: 60.872-60.904 longitude: 5.407-5.509 quality_description: Each profile of the total data set was given a quality flag following the Oceansites reference manual (http://www.oceansites.org/docs/oceansites_data_format_reference_manual.pdf). title: CTD profiles and bottle data from 60.872 - 60.904 N, 5.407 - 60.904 E in Vestland, Norway sampled during KB2021620, 26.08.2021, 06:52 - 26.08.2021, 09:15 UTC. summary: The file contains temperature, practical salinity, and oxygen measurements binned into 1 db pressure bins. The raw data was measured using a Seabird SBE 11plus V 5.2 CTD and post-processed with the Seasoft software package following IMR, Norway standard procedures. Only data from the downcast of the profile was used. If available, water sample data (DIC, TA, nutrients, Oxygen) collected during the cruise is included, as well as (uncalibrated) profiles of par, spar, transmission and flourescence. keywords: EARTH SCIENCE>OCEANS>OCEAN TEMPERATURE>WATER TEMPERATURE, EARTH SCIENCE>OCEANS>OCEAN PRESSURE>WATER PRESSURE,EARTH SCIENCE>OCEANS>SALINITY/DENSITY>SALINITY keywords_vocabulary: GCMD Science Keywords naming_authority: HI/NMDC data_type: CTD feature_type: Profile flag_values: 0,1,2,3 flag_meaning: 0= (probably) good data (sp and o are calibrated), 1 = uncalibrated, raw data (visually inspected), 2 = data outside of calibration range (O2),3 = Potentially bad data location: Geographic Region>Polar geospatial_lat_min: 60.872 geospatial_lat_max: 60.904 geospatial_lon_min: 5.407 geospatial_lon_max: 5.509 area: Vestland, Norge (Masfjorden) time_coverage_start: 2021-08-26T06:52:51Z time_coverage_end: 2021-08-26T09:15:14Z Conventions: CF-1.6, ACDD-1.3 date_created: 2023-06-14T14:09:16 history: File created at 2023-06-14T14:09:16 using xarray in Python3. processing_level: Post-recovery calibrations have been applied, data manually reviewed. creator_type: person creator_institution: Geophysical Institute, University of Bergen creator_name: Elin Darelius creator_url: https://orcid.org/0000-0003-3060-0317 creator_email: elin.darelius@uib.no;;;;;;;;;;;;;;;;;;;;;;; institution: Geophysical Institute, University of Bergen principal investigator: Arild Folkvord source: CTD profile platform: Water-based Platforms>Vessels>Surface>Kristine Bonnevie license: https://creativecommons.org/licenses/by/4.0/ iso_topic_category: oceans publisher_name: Norwegian Marine DataCentre (NMDC) publisher_url: https://www.nmdc.no publisher_email: datahjelp@imr.no period: 2021-08-26 - 2021-08-26 Bottle_data:Numbers_of_samples_analysed: 14 dissolved oxygen (DO) samples.
