Analyses of new shipboard and ROV observations of bedrock channels carved by floods and outbursts from subglacial lakes under Antarctica shed light on complex subglacial processes.
Deep-ocean-dwelling microbes may hold keys to improved medical diagnostics and new drugs for fighting diseases. But we must search Earth’s most extreme habitats to find them.
Building on the successful Argo network of seafaring temperature and salinity sensors, work is underway to deploy 1,000 floats equipped to study ocean biogeochemistry in greater detail than ever.
Researchers devised a simple way to deliver ocean bottom seismometers accurately to the seafloor to study ongoing seismic and volcanic activity near the islands of Mayotte.
Ancient Polynesian voyagers sailed thousands of kilometers with no maps or compasses; they followed nature’s clues. Using the same tools, the Moananuiākea Voyage will set sail from Alaska and circle the Pacific.
A recent expedition mapped one of the world’s longest submarine channels, revealing previously undiscovered physical features and raising questions about its unusual origin and shape.
Scientific ocean drilling is an enduring paragon of global research, advancing knowledge of Earth and informing scientists and educators for 55 years. A new road map plots the way to further discovery.
The successful deployment of a seafloor seismometer near the calving front of a Greenland glacier has opened a new avenue to study hidden glacial processes and the behavior of fjord-dwelling wildlife.
A new study shows that icebergs may initiate submarine landslides when they collide with the seafloor.
Scientists discovered magmatic remnants of a volcanic arc by dating granitic rocks of the middle crust excavated by, and hidden within, the Chicxulub impact crater.
