Melting glaciers might be making ocean water more acidic, an unexpected finding that's given scientists new cause for concern. A new study published yesterday in the journal Nature Climate Change suggests surprising ways that climate change is drastically altering the water chemistry in deep seas—a process that may happen faster than researchers anticipated.
Researchers Find Way To Chart Changes In The Speed Of Deep-Ocean Currents Using The Most Modest Of Materials—Mud
(Click to enlarge) (Credit: Leo Pena) Researchers have found a way to chart changes in the speed of deep-ocean currents using the most modest of materials – mud. The approach, reported in the journal Deep-Sea Research Part I, could provide scientists with a better basis for understanding the behaviour of ancient ocean currents and, [...]
Observed at a staggering depth of more than 8,000 feet below the surface of the ocean, scientists think they may have found a new species. The small wriggling creature is a snailfish and comes from the family Liparidae. For having been found at the depths of the ocean, the snailfish is unexpectedly cute, more resembling a small minnow than one of the ocean's deep creatures.
Two years ago, Shana Goffredi raced to the control room of the R/V Western Flyer, a 117-foot-long research ship in the Gulf of California. Television monitors onboard the vessel displayed what looked like an alien world near the ocean bottom, and Goffredi wanted to get a better look. On screen were thousands of tiny orange tube worms and dozens of other animals, some of which were new to science. The bizarre habitat gleamed in the lights of an underwater robotic probe as it explored the environs of a seafloor spring spewing water at superhot temperatures—known as a hydrothermal vent. What struck Goffredi, a marine biologist at Occidental College, along with the 10 other scientists onboard was how different the life-forms at this site, called the Pescadero Basin, looked from those at a neighboring site.
Despite being relatively close together, two recently discovered hydrothermal vent fields in the Gulf of California host very different animal communities. This finding contradicts a common scientific assumption that neighboring vents will share similar animal communities, and suggests that local geology and vent-fluid chemistry are important factors affecting vent communities.
While the waters of the North Atlantic and South Pacific tend to have what hard corals need to survive, the North Pacific doesn't, and it has been thought that deep-sea coral reefs were a near impossibility in that part of the ocean. But researchers at Florida State University and Texas A&M University have discovered a few reefs in the North Pacific that don't seem to be following the rules. Their findings were recently published in Scientific Reports.
The Cooperative Institute for Ocean Exploration, Research, and Technology (CIOERT), based at FAU Harbor Branch, recently led a collaborative scientific expedition to Cuba, exploring never-before-studied mesophotic coral reefs from 30 m to 150 m. After nearly a year and half of planning, the research cruise, "Cuba's Twilight Zone Reefs and Their Regional Connectivity," circumnavigated Cuba in just one month.
Scientists have discovered the reason why some deep-sea coral reefs glow in the dark. Researchers from the University of Southampton found corals in deep water survived by making a special type of fluorescent protein. The research found the proteins responsible for acting as sunblock in corals in shallow waters worked differently in deep-sea reefs.
Biodiversity losses from deep-sea mining are unavoidable and possibly irrevocable, an international team of 15 marine scientists, resource economists and legal scholars argue in a letter published today in the journal Nature Geoscience.
