Using ROVs to monitor sea cucumber stocks in WA

The Department of Primary Industries and Sustainable Development has been using ROVs to conduct marine invertebrate surveys in Western Australia:

“Utilising the ROVs rather than having divers in the water is about personal safety for our researchers to avoid potential injury from hazardous marine life in the Kimberley waters, including crocodiles, sharks and lethal box and irukandji jellyfish,” [DPIRD Principal Research Scientist Lachlan Strain from the Aquatic Science and Assessment branch] said.

Of all the unusual things to find, researchers at Monterey Bay Aquarium Research Institute (MBARI) found and retrieved a mammoth tusk at a depth of ~3,000m (10,000 ft) off the coast of California!

“This specimen’s deep-sea preservational environment is different from almost anything we have seen elsewhere,” said University of Michigan paleontologist Daniel Fisher, who specializes in the study of mammoths and mastodons. “Other mammoths have been retrieved from the ocean, but generally not from depths of more than a few tens of meters.”
