The Federal Fisheries Council has approved the entry of the British research vessel James Cook into the Argentine Sea to conduct a campaign, despite concerns about the lack of details about the type of data to be collected and the instruments to be used. The campaign is focused on two projects: RIBOD, which aims to analyze surface submesoscale currents, and COSSMoSS, which seeks to understand how oceans flow in the depths. The latter has raised concerns due to the use of powerful acoustics and seismic imaging techniques, which could cause environmental damage to mammals like the southern right whale. Despite these concerns, the data collected is expected to provide insights into the internal dynamics of the South West Atlantic and quantify regional exchanges of energy, heat, and nutrients.
