Mapping Mud Volcanoes in Shallow Seas
A team of scientists put together a global database of submarine mud volcanoes. Orders of magnitude more are still bubbling, undiscovered, in the deep ocean.
Biomass and Biodiversity Were Coupled in Earth’s Past
Measuring shells and skeletons encased in thousands of limestone samples has revealed that the sheer amount of living stuff in Earth’s oceans changed alongside the diversity of organisms.
Scientists Face Limitations Accessing Seafloor Information
Recent reductions in U.S. oceanographic assets are limiting scientists’ ability to access vital materials in the ocean.
More Bubbles Means More Variation in Ocean Carbon Storage
A new model accounting for the role of bubbles in air-sea gas exchanges suggests that ocean carbon uptake is more variable than previously thought.
Warming Gulf of Maine Buffers Ocean Acidification—For Now
Scientists constructed a 100-year history of acidity in the Gulf of Maine. They expected coastal variability but were surprised by what they didn’t find: a strong anthropogenic signal.
New Satellite Adds Evidence of an Earth-Shaking Wave
A tsunami struck a fjord in East Greenland in 2023, ringing seismometers for nine straight days. A new satellite study provides the first observational evidence of the waves.
Finding Consensus on Arctic Ocean Climate History
Understanding the effects of a “blue” Arctic Ocean on future climate requires a coordinated effort to study Earth’s past warm periods using a variety of classical and cutting-edge methods.
Where Do Antarctic Submarine Canyons Get Their Marine Life?
A new study investigates how much of the phytoplankton in the Palmer Deep submarine canyon is homemade and how much is delivered.
Kuroshio Intrusions into Luzon Strait Increase Chlorophyll
Using in-situ observational data, scientists reveal that Kuroshio intrusions through the Luzon Strait increase small phytoplankton in the South China Sea.
Two Equations that Unlock El Niño
Despite the El Niño–Southern Oscillation’s global reach and complex ocean–atmosphere interactions across timescales, two simple, elegant equations capture its key dynamics and defining properties.
