Even seagrass affected by noise pollution says new study -- Science & Technology -- Sott net

Fri, 23 Jul 2021 00:13 UTC Seagrass may not have ears, but that doesn t stop noise pollution from causing serious damage to the plant s other structures. © Shane Gross/NPL/Minden Pictures Noise pollution affects the structures within seagrass that help the marine plant detect gravity and store energy.From the whirring propellers that power our ships, to the airguns we use to search for oil, we humans have created a cacophony in the ocean. For years, scientists have known that human-generated noise pollution can hurt marine animals, including whales, fishes, and scallops. However, the damaging effect of noise pollution is, apparently, not limited to animals with ears, or even animals at all.

Renowned UCSD research ship Roger Revelle prepares for trip to Antarctica

Print UC San Diego is preparing to send its famous research ship Roger Revelle on its first trip to Antarctica since the vessel completed a $60 million mid-life overhaul earlier this year. The ship, which is named for the school’s chief founder, will travel to the Southern Ocean off Antarctica to study the Great Calcite Belt, whose coccolithophores, or phytoplankton, can reflect light visible from satellites. The belt sends nutrients to other regions of the world, broadly affecting the productivity of marine life. It also can affect global climate patterns, which will be the primary focus of the two-month expedition that begins on Dec. 26. The expedition will be led by Barney Balch, a UCSD graduate who works at Maine’s Bigelow Laboratory for Ocean Sciences.
