CONICET Launches Patagonian Submarine‑Canyon Expedition With Live Deep‑Sea Streams

The mission tests how Patagonian canyons shape exchanges with the Malvinas Current using advanced sensors.

Overview

  • The monthlong campaign began September 30 aboard the Schmidt Ocean Institute’s Falkor (too) and is scheduled to run into late October, with outlets listing an end date of either October 29 or 30.
  • Researchers will survey the Bahía Blanca canyon system off Viedma before moving to the Almirante Brown canyons off Rawson, roughly 450–500 kilometers offshore.
  • Operations include live‑streamed ROV SuBastian dives, autonomous surveys, a fixed SHN buoy measuring currents and temperature, GPS‑tracked drifters, and collection of water, sediment, and plankton samples.
  • The team will map canyon morphology and measure flows to assess how these non‑blind canyons facilitate exchanges between continental‑shelf waters and the Malvinas Current.
  • Streams will air on the Schmidt Ocean Institute YouTube channel, with the effort backed by the institute, Fundación Williams, SHN, INIDEP, and CONICET units, following a prior Mar del Plata mission that drew large audiences and flagged dozens of candidate new species now under analysis.
