Youve reached the oceans midwater, or twilight zone, a several-thousand-foot stretch of the water column where light eventually becomes nearly unmeasurable. While the surfaces of these vast bodies of water have absorbed the vast majority of human-induced warming, as sea water circulates, the worrisome changes are slowly making their way downward. Others just take a stroll. In the oceans shadowy twilight zone, between 600 and 800 metres beneath the surface, there are fish that gaze upwards through their transparent heads with eyes like mesmerising emerald orbs. March 24, 2021|Arizona State University News. Then 100 meters. He witnessed another eject a toxic plume that was killing and stunning fish and squid, which rained down to be eaten by crabs, worms, and shrimp. Institutions must invest in their own fleet and crew or rely on shared vessels, where demand greatly exceeds capacity. One ocean milestone of note this year is that National Oceanic and Atmospheric Administration (NOAA) Ocean Explorations marked its 20th year of discovery. In what could mark a significant step forward for the development of unmanned autonomous vessels, the French classification society Bureau Veritas awarded its first Approval in Principle (AiP) for an unmanned surface vessel. An influential current system in the Atlantic Ocean, which plays a vital role in redistributing heat throughout our planet's climate system, is now moving more slowly than it has in at least 1,600 years. These behemoths lived alongside squid-like ammonites encased in tightly-coiled shells and a slew of bizarre fish.

Aiming to bolster conservation on the high seas, a team of marine researchers today released the first comprehensive survey of coral reefs in the high seasthe roughly two-thirds of the ocean outside of national jurisdictions. We work with governments around the world interested in identifying mineral resources in Exclusive Economic Zones, focusing on phosphorite (fertilizer) and polymetallic nodule (battery metals) projects. Instead, it might possibly host massive ocean currents, driven by changes in salinity. Here on Earth, we have more detailed maps of Mars than of our own ocean, and thats a problem. Researchers with the National Oceanic and Atmospheric Administration (NOAA) are conducting a search of the Pacific Ocean for whats been dubbed the largest graveyard of aircraft downed during the Second World War. Marine geophysical, geotechnical & geochemical surveys - OFG Were vowing to explore and map the entirety of Earths oceans. With assistance from roughly 300 scientists affiliated with the funding body the Alfred Wegener Institute, the mission recovered invaluable data regarding the Arctic environment, but reached a saddening conclusion: The Arctic is still melting. This question is the focus of a close scientific cooperative effort between the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and MARUMCenter for Marine Environmental Sciences at the University of Bremen.
