Short summary
As part of the new Fisheries Act, Fisheries and Oceans Canada (DFO) has made it a priority to make oceanographic data publicly available. The Canadian Atlantic Shelf Temperature-Salinity (CASTS) aims to address this priority, by creating an open-access data product that includes most of the historical temperature and salinity profiles in Atlantic Canada and its Arctic gateways since 1873.
