More and more organizations are moving away from the use and release of balloons in any form, for good reason. A study by the Institute for Marine and Antarctic Studies (IMAS) and CSIRO found that, although hard plastic accounts for the vast majority of debris ingested by seabirds, it is far less likely to kill than soft plastics such as balloons. “Although soft plastics accounted for just 5% of the items ingested, they were responsible for more than 40% of the mortalities”.

ROV “Beast” filming under Arctic Ice

Scientists from the Alfred Wegener Institute have been using an ROV, nicknamed “Beast” to explore and film under sea ice in the Arctic, as part of the Multidisciplinary Drifting Observatory for the Study of Arctic Climate Change (MOSAiC). The team found some amazing platelet ice crystals, feathery ice crystals that form at supercool temperatures and grow as large as a human hand, typically found in Antarctica, not the Arctic.

NOAA Discovers Deep Sea “Balloon-like” Jelly

A new species of carnivorous comb jelly (ctenophore) was found by NOAA’s ROV Deep Discoverer near Puerto Rico at a depth of ~4000m.

The comb jelly, or ctenophore, was first seen during a 2015 dive with the NOAA Office of Ocean Exploration and Research team.
