AUV’s Epic Two and a Half Year Journey Sampling Ocean and Ice Shelves for Argo Program

Australia’s CSIRO used an AUV to collect an unprecedented amount of oceanic data during more than 2.5 years travelling ocean currents, including dives below the Denman and Shackleton Ice Shelves, as part of the Argo survey project.

The data will help “improve climate computer models and reduce uncertainties about sea level rise.”

DVLs Helping Divers as well as ROVs

We don’t usually see divers using technology designed for ROVs but Subsea Artemis is making it happen:

Accurate positioning and dead-reckoning navigation capabilities are essential for maintaining situational awareness and keeping divers safe during long-duration underwater missions. Blueprint [Subsea’s Artemis diver navigation system] relies on Nortek’s DVL technology as part of these diver navigation systems to provide accurate velocity information in challenging underwater environments.

WHOI launched AUV to Circumnavigate the Globe

In a world first, WHOI (Woods Hole Oceanographic Institute) launched an AUV programmed to circumnavigate the globe, following a path similar to the Magellan Expedition of 1519.

The AUV is expected to take more than five years to complete the journey, covering roughly 73,000 km (~45,000 miles) at an average speed of 0.75 knots.

ROV Finds Hidden Canyon in Mediterranean, Teaming with Life Under Threat

Italian marine biologists joined the One Ocean Foundation to deploy an ROV and explore the Caprera Canyon off the coast of Sardinia in the Mediterranean Sea, at a depth of >1,00m (3,281 feet). Teaming with life, the creatures there are struggling to survive tangled in plastic or choked by discarded fishing gear.

One Ocean Foundation hopes that imagery captured will help to strengthen the case for designating the canyon a Marine Protected Area (MPA), safeguarding it from overfishing and pollution.
