Oceanographic data from cruise JC142 to Tropic Seamount, in the Northeast Atlantic, as part of the MarineE-tech project (October-December 2016).

This dataset consists of processed products from shipboard ADCP, salinity, temperature, pressure, oxygen data and ADCP data from CTD casts, ADCP current profilers and turbidity measurements from a seafloor lander, and turbidity measurements from an AUV (Autosub6000), acquired at Tropic Seamount off the North-west African coast during RRS James Cook cruise JC142, from October to December 2016. These data were collected as part of the MarineE-tech project, one of four consortium projects of the NERC SoS Minerals research programme. 18 CTD stations, with a total of 37 CTD casts completed as well as four lander stations and three AUV surveys were occupied. This includes a single station on the central-plateau where 8 CTD yo-yo casts were performed to detect the presence of internal tides and internal waves. The data provided verification data for the numerical model developed by HR Wallingford, and aided particulate organic carbon and microbiological studies as well as plume dispersion experiments. The work was undertaken by scientists at the National Oceanography Centre, Southampton, HR Wallingford, and the University of Sao Paolo, Brazil.
