Description
***** Dataset abstract *****
This data set contains measurements from various sensors mounted on the Conductivity, Temperature, Depth (CTD) rosette that was deployed in the Southern Ocean during the Antarctic Circumnavigation Expedition (ACE). 63 CTD casts were carried out during three legs in the period 21st December 2016 to 16th March 2017, including one test cast and one failed cast, for which no data is available. Data include temperature, salinity, pressure, dissolved oxygen, oxygen saturation, chlorophyll-a concentration, backscatter, and photosynthetically active radiation (PAR) and reported are also the computed variables density, depth, and sound velocity. All data has been quality controlled and post-cruise calibrated, except for the oxygen data. Data is provided at 1 dbar pressure intervals for the up- and down-casts separately and as a merged bottle file when Niskin bottles were closed. This circumpolar data set provides insights into the circumpolar hydrography and biogeochemistry of the Southern Ocean during one austral summer season.
***** Dataset contents *****
For transparency, the raw files and files produced at the intermediate stages of data processing have been provided, in addition to the final processed files.
Raw data files:
- ace_ctd_raw_files.zip - includes raw files direct from instrument and XMLCON configuration files
Intermediate files:
- files output at each stage of the SeaBird processing
Processed data files:
- ace_ctd_CTD20190805CURRSGCMR - one final set of files for the complete sensor data;
- ACE_BOTTLE20190807CURRSGCM_hy1.csv - a merged bottle file extracted from the sensor data is also provided
Metadata:
- range of files describing the CTD deployments, sensors, water sampling, quality-checking and processing of the files.
