The best way for recreational fishers to release red snapper and red grouper caught in the deeper waters of the Gulf of Mexico -- and physically traumatized from the pressure change experienced during the ascent -- is to use a descending device.

Which barotrauma mitigation method is best for red snapper and red grouper caught in deep water? Recompression outperforms venting, according to Gulf of Mexico study

The best way for recreational fishers to release red snapper and red grouper caught in the deeper waters of the Gulf of Mexico -- and physically traumatized from the pressure change experienced during the ascent -- is to use a descending device.

CMS professor Brad Rosenheim and his former PhD student, Ryan Venturelli, upon arrival to McMurdo Station in Antarctica. McMurdo station is one of three US stations for scientific research in Antarctica—located >600 miles from Mercer Subglacial Lake.

Scientists describe carbon cycle in a subglacial freshwater lake in Antarctica for first time

Surprising results from historic study suggest the shrinking West Antarctic Ice Sheet, a major threat to global sea level rise, was smaller and more dynamic in recent geologic past than previously thought.

The sea urchin killer

Scientists identify 2022 sea urchin killer

The mass die-off of the long-spined sea urchin – a loss that threatens the health of coral reefs from the Caribbean to Florida’s east coast -- was caused by a one-celled organism called a ciliate.

Doubtful Sound, New Zealand, which Dr. Xingqian Cui visited in 2016, was apparently so-named because its discoverer, Captain James Cook, decided if he and the crew ventured into the fjord during a voyage in 1770, it would be “doubtful” that they would be able to sail back out of the fjord against the westerly wind.

Fjords: small-but-mighty planetary “thermostats” whose role in the global carbon cycle is both sink and source

If you’re worried about escalating human-induced climate change, consider adding fjords to your thank-you list during this season of gratitude.

Distinguishing the influence of sediments, the Congo River, and water-mass mixing on the distribution of iron and its isotopes in the Southeast Atlantic Ocean

Iron is a key micronutrient for primary production in the surface ocean. Iron isotopes can provide a window into the sources and cycling of iron to the surface and deep ocean.
