Argentina Approves US Oceanographic Cruise Amidst 'Dual-Use' Data Concerns

Argentine Council Grants Approval for US Research Vessel

Argentina's Federal Fisheries Council (CFP) has formally approved a request from the United States for a marine scientific research cruise to operate within Argentina's Exclusive Economic Zone (EEZ). The research vessel, R/V Roger Revelle, is scheduled to conduct its operations between March 5 and March 30, 2026. This authorization follows diplomatic notes from the US Embassy and has generated discussion within Argentine political and defense circles regarding the potential 'dual-use' nature of the data collected.

Cruise Objectives and Vessel Details

The R/V Roger Revelle, operated by the Scripps Institution of Oceanography (UC San Diego) under a charter agreement with the Office of Naval Research, is owned by the US Navy. The cruise is part of the international GO-SHIP program, an initiative focused on repeating trans-basin hydrographic sections to document shifts in heat, freshwater, carbon, nutrients, and oxygen. Its specific objective in the South Atlantic is to continue measurements tracking changes in temperature, oxygen, and anthropogenic CO₂. The planned work area spans 42°S to 48°S and 59°W to 63°W.

Debate Over 'Dual-Use' Data

The approval has ignited criticism in Argentina, centered on the potential military applications of certain research outputs. Critics highlight that the R/V Roger Revelle is equipped with advanced instrumentation, including multibeam echosounders for high-resolution seafloor mapping and systems for broad oceanographic measurements. These capabilities, particularly bathymetry and acoustic-relevant measurements, are considered to have 'dual-use' value, meaning they could serve both scientific and military purposes. Concerns have been raised, especially given the vessel's ownership by the US Navy and the long-standing sovereignty dispute between Argentina and the United Kingdom over the Falkland Islands (Malvinas).

Argentine Oversight and Data Requirements

In response to these concerns, the Federal Fisheries Council stipulated conditions for the cruise. The CFP recorded that it had 'no objections' to the request, but mandated that 'all basic data' as well as 'preliminary and final reports' must be submitted to Argentine authorities prior to any publication of results. Furthermore, an Argentine scientific observer from the National Institute for Fisheries Research and Development (INIDEP) will be onboard the R/V Roger Revelle during its operations. This measure aims to ensure transparency and allow Argentine authorities to access and review the cruise's outputs directly.
