How the Rise of a Salty Blob Led to the Fall of the Last Ice Age
Scientists have long suspected that high salinity levels in the deep ocean were responsible for keeping carbon dioxide locked away during the last ice age. New research finds the strongest evidence yet.
Marine Snow Grows Faster and Fluffier as It Sinks
New observations highlight how abiotic and biotic processes influence the tiny oceanic particles.
How a Move to the Shallows 300,000 Years Ago Drove a Phytoplankton Bloom
And what that could mean for today’s ocean.
Las olas de calor marinas lentifican el flujo de carbono de los océanos
Cuando el plancton se encuentra en agua caliente, la materia orgánica se estanca en la superficie e interrumpe el transporte de carbono hacia el fondo océanico.
Wintertime Spike in Oceanic Iron Levels Detected near Hawaii
Seasonal rainfall and runoff of sediments from the Hawaiian Islands could be responsible for the previously undetected peak.
Glacier Runoff Becomes Less Nutritious as Glaciers Retreat
Sediment from retreating, land-terminating glaciers contains proportionally fewer micronutrients such as iron and manganese, reducing the glaciers’ value to microorganisms at the base of the food web.
How Algae Helped Some Life Outlast Extinction
Cooler waters near Norway’s north provided a refuge for phytoplankton during the Great Dying, a new study suggests.
Marine Heat Waves Slow the Ocean’s Carbon Flow
When plankton find themselves in hot water, organic matters stalls at the surface and disrupts transport of carbon to the deep ocean.
