A Global Ocean Biogeochemical Observatory Becomes a Reality
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.
Once Extreme Ocean Temperatures Are the New Normal
A new analysis finds extreme warming events in the ocean have increased relative to the very far past, with nearly 60% of the ocean experiencing extreme heat in 2019.
Satellites Help Cement South Africa’s Space Industry
A trio of CubeSats allows South Africa to showcase its growing space industry as well as monitor its coastal zones.
A Cagey Approach to Speedy and Safe Seafloor Deployments
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.
Lipids from Europa’s Ocean Could Be Detectable on the Surface
A super salty spring in the Canadian Arctic provides insights key to detecting life on a distant ocean world.
Finding Moons’ Hidden Oceans with Induced Magnetic Fields
A principal component analysis of speculative models can more confidently predict the presence of a planetary object’s subsurface ocean than previous techniques.
The Bumpy Search for Liquid Water at the South Pole of Mars
Studies since 2018 have provided competing explanations of bright radar reflections from the base of the south polar ice cap.
Geochemical Data from Polynesian Artifacts Pack Pofatu Database
A new resource may help match artifacts with their original stone sources—“a really a niche part of archaeology that requires geological expertise.”
The Seasonality of Oceanic Carbon Cycling
Scientists uncovered how seasonal changes affect the amount and rate of carbon as it moves from the ocean’s surface to its depths.
