This study compares the noise levels at the cold-water coral Tisler reef, before and after the closure of the border between Norway and Sweden, which occurred as a direct result of the COVID-19 pandemic. The Tisler reef is a marine protected area located under a ferry “highway” that connects Norway and Sweden. Cold-water coral reefs are recognised as being important hotspots of both biodiversity and biomass, they function as breeding and nursing grounds for commercially important fish and are essential in providing ecosystem functions. Whilst studies have shown that fishery, ocean warming, and acidification threaten them, the effects of noise pollution on cold-water coral reefs remains unstudied. To study the severity of noise pollution at the Tisler reef, a long-term acoustic recorder was deployed from 29 January 2020 until 26 May 2020.

Spotlight on Fast Oceanographic Automated Measurement system February 11, 2021, by Eldin Ganic
Sequoia Scientific, Ocean Instruments and Sequoia’s Dutch distributor, Geometius, have delivered a Fast Oceanographic Automated Measurement (FOAM) system for dredge monitoring.
The FOAM system is composed of a pump and winch with a fluid rotary joint, 100 m hybrid cable with hose and conductors, a tow sled with an RBR CTD and a Sequoia LISST-ABS, and a topside mounted Sequoia LISST-200X running in flow-through mode.
The sled is towed through the dredge plume, while water is continuously pumped through the hybrid cable and winch to the topside LISST-200X.
AGU: Few Studies Focus On Fish Communication - 12:30 pm
Underwater recorders, known as ‘hydrophones’, are deployed near the seafloor for months to years at a time. Shallow locations are maintained by divers, while deeper locations contain ‘acoustic releases’ that can be triggered with a signal to send the equipment back to the surface for retrieval.

AGU News:
Abstract – Ocean acoustics is a rapidly growing field, yet few studies have focused on fish communication. Understanding fish signaling is crucial for recognizing how fish behave in different habitats and during critical time periods such as their mating season.
