The ocean dynamic datasets of seafloor observation network experiment system at the South China Sea

The ocean dynamic datasets of seafloor observation network experiment system at the South China Sea was completed in September 2016. This system provided energy supply and communication transmission channel through optical fiber composite power cable for the deep ocean observation platform, enabling multi-parameter, real-time and continuous ocean observation. The Subsea Dynamic Platform with CTD and ADCP was deployed in June 2017, and the collection of observation data was started from July 2017, including the collection of temperature, conductivity, water pressure from CTD and velocity from ADCP. Based on the raw observation data collected by ADCP and CTD sensors from July 2017 to December 2018, the data processing and quality control algorithm is adopted to remove outliers, add missing values, format the data and finally produce the dataset. The dataset provides basic data for oceanographic research.The dataset consists of 4 data files in total: 2017_ADCP_dataset.NC with data volume of 8.98 MB, 2018_ADCP_dataset.NC with data volume of 17.6 MB, 2017_CTD_dataset.NC with data volume of 29.5 MB, 2018_CTD_dataset.NC with data volume of 60.6 MB.
