Variations in Earth’s Orbit Drove Biological Evolution of Coccolithophores
Coccolithophores are microscopic algae that form tiny limestone plates, called coccoliths, around their single cells. The shape and size of coccoliths varies according to the…
New Technology Shows Climate Change Is Making One of the World’s Strongest Currents Flow Faster
A change in the Southern Ocean, the region absorbing the most human-induced warming globally, is detected by new technology. The Antarctic Circumpolar Current (ACC), the…
New Possibilities for Life in the Strange, Dark World at the Bottom of Earth’s Ocean – And Perhaps in Oceans on Other Planets
In the strange, dark world of the ocean floor, underwater fissures, called hydrothermal vents, host complex communities of life. These vents belch scorching hot fluids…
Climate Change Will Destroy Environments, Create New Ones, and Undermine Efforts To Protect Sea Life
Climate change is altering familiar conditions of the world’s oceans and creating new environments that could undermine efforts to protect sea life in the world’s…
Flawed Climate Models? Arctic Ocean Started Getting Warmer Decades Earlier Than We Thought
The Arctic Ocean has been getting warmer since the beginning of the 20th century – decades earlier than records suggest – due to warmer water…

Marine Carbon Sequestration: New Research Delves Into Fate of Ocean Carbon
Marine-dissolved organic matter, which originates from phytoplankton, holds as much carbon as Earth’s atmosphere, yet the biological processes governing its fate are primarily studied under…
Ancient Driftwood Tracks 500 Years of Arctic Warming, Currents, and Sea Ice
Fallen trees kept afloat in sea ice reflect accelerated ice loss in the last 30 years. A new study reconstructs the path of frozen trees…
Massive Flying Laboratory Uncovers Secrets of How Marine Life Influences Cloud Formation
Ocean Life Helps Produce Clouds, but Existing Clouds Keep New Ones at Bay Stand on the ocean’s shore and take a big whiff of the…
Earth Is Dimming – It’s Due to Climate Change
Warming oceans cause fewer bright clouds to reflect sunlight into space, admitting even more energy into earth’s climate system. Warming ocean waters have caused a…
Australian Wildfires Triggered Massive Algal Blooms in Southern Ocean – Raises New Questions About Oceanic Carbon Uptake
Boom in carbon-sequestering phytoplankton raises new questions about oceanic carbon uptake and productivity. Clouds of smoke and ash from wildfires that ravaged Australia in 2019…
Subtle Cloud Shadows Cue Mini-Migrations
Zooplankton swim up and down repeatedly due to subtle changes in daylight intensity. Cued by the setting sun, droves of zooplankton and small fish each…
Climate Change Likely To Abruptly Impact Algae in the Global Ocean
