leonid polyak, Arctic Ice Shelf Theory Challenged by Ancient Algae
OCEANS ARCHIVE
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.
When Should a Tsunami Not Be Called a Tsunami?
It’s time to redefine the term so it more clearly conveys meaningful risks to coastal communities and prompts them to act when needed.
Tiny Turbulent Whirls Keep the Arctic Ocean Flowing
Centimeter-sized turbulence controls the rate at which the Arctic Ocean churns.
Hydrothermal Circulation and Its Impact on the Earth System
From a gathering of scientists at a uniquely well-preserved section of ancient oceanic crust came a monograph investigating the latest in hydrothermal fluxes and seawater chemistry.
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.
Echoes From the Past: How Land Reclamation Slowly Modifies Coastal Environments
Reclamation of tide-influenced areas has a large impact on coastal environments through gradual modification of tidal dynamics, erosion, and siltation.
A New Way for Coastal Planners to Explore the Costs of Rising Seas
A framework featuring a range of plausible future sea level rise scenarios could help coastal planners prepare critical infrastructure for the worst-case scenario.
Ocean Tunneling May Have Set Off an Ancient Pacific Cooldown
The ocean’s depths cooled off about 1.5 million years ago, and scientists think watery tunnels from the south may be to blame.
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.
古气候模式为未来变暖提供线索
一项新研究分析了过去1000万年的海洋表面温度数据，以预测未来变暖的可能走向。
