Illustration showing the effects of two Beaufort Gyre air pressure shifts
Map illustrating how physical ocean processes surrounding the Beaufort Gyre in the Arctic may be affected by climate change.
Read MoreHow bacteria is transported through the environment into the ocean
Wastewater carries antibiotics and bacteria to oceans, where antibiotic-resistant microbes emerge. Researchers study these impacts on marine and human health.
Read MoreGrowing bacteria in petri dishes applied with antibiotics
Antibiotics can encourage antibiotic resistance by killing off all the susceptible bacteria and leaving only the resistant bacteria to grow and multiply.
Read MoreAtlantic Ocean currents carrying warm water up to Greenland
3D map illustrating ocean currents in the North Atlantic, combined with seafloor bathymetry.
Read MoreAtlantic Ocean currents circulation
Scientists use models to reveal how shifts in ocean currents—like a global heat conveyor—can trigger major climate changes across millennia.
Read MoreTerritorial Arctic map
Multiple countries control territories within the Arctic circle, with Russia alone accounting for 53% of the Arctic coastline.
Read MoreBoundaries of the Arctic region
Map showing Arctic boundaries including the Arctic Circle, tree line, July isotherm, permanent sea ice extent, and surrounding countries.
Read MoreChanges from 2007 to 2015 on the release of radium in the Arctic
As Arctic sea ice melts, waves stir up coastal sediments, releasing chemicals into the ocean—signaling rapid climate-driven changes that may disrupt Arctic ecosystems.
Read More2011 global hydrothermal vents
2011 map showing the global distribution of hydrothermal vent locations, either suspected or confirmed.
Read More2009 global hydrothermal vents
2009 map showing the global distribution of hydrothermal vent locations, either suspected or confirmed.
Read MoreBiological Carbon Pump
The ocean’s biological carbon pump moves carbon from surface waters to the deep sea, helping regulate climate by keeping some heat-trapping gases out of the air.
Read MoreMixing layer diagram
Interactions between the ocean and the atmosphere, illustrating how energy and matter are exchanged between these two systems.
Read MoreThe life cycle of Greenland’s meltwater lakes
Meltwater lakes on Greenland’s ice sheet drain to bedrock each spring, potentially speeding ice loss and accelerating global sea level rise.
Read MoreCesium-137 movement from Fukushima in coastal saters
Radioactive cesium from Fukushima was carried by currents, trapped in beach sands, then released back to the ocean as saltwater conditions changed.
Read MoreThe Ocean of Things
The digital ocean ecosystem of the future will rely on a network of underwater vehicles, sensors, and communications systems that will be always on and always connected.
Read MoreIs the mantle one big pot or is it double-decked?
The flow of rocks in the mantle drives geological phenomena like earthquakes and volcanoes. Scientists are studying if the mantle convects as a whole or in layers.
Read MoreThe birth of a black smoker
Black smoker chimneys form as hot vent fluids mix with cold seawater, first building walls of anhydrite, then layering on metal sulfides over time.
Read MoreThe seafloor is teeming with methane
Methane seeping from the seafloor fuels deep-ocean ecosystems where microbes use it for energy, supporting unique animals in dark, sunlight-free habitats through chemosynthesis.

An exploration of how and why manganese oxide deposits form in the environment
Read MoreTwo subspecies of pilot whales identified
New research reveals that short-finned pilot whales are not one, but two distinct subspecies, changing our understanding of their diversity.
Read MoreUnderwater charging stations positioned along a mooring line
Underwater charging stations, like the one rendered here, could allow ocean robots to run longer-distance missions while reducing the time and costs.
Read MoreDecoding microbes by their lipids
Scientists use lipid chemistry to identify ocean microbes—distinguishing light-powered autotrophs from carbon-processing heterotrophs in seawater samples.
Read MoreLibrary of Sand
Nothing says coastline like sand, that soft edge between land and sea. Sand takes millions of years to form, created as nearby rock weathers into fine grains.
Read MoreLife and chemistry at deep-sea hydrothermal vents
Hydrothermal vents host extreme microbes that drive key chemical cycles—oxidizing sulfur, fixing CO?, and producing methane in a hot, mineral-rich environment.
