Marine algae known as coccolithophores produce much of the ocean's calcium carbonate. A large survey reveals how these organisms' calcification processes and species distribution change in response to carbon dioxide levels.

The Atlantic Ocean receives warm, saline water from the Indo-Pacific Ocean through Agulhas leakage around the southern tip of Africa.

Japan Readies To Inject Nitrogen Into Reactor To Prevent Blast After Hydrogen Buildup
Tokyo: Workers stopped a highly radioactive leak into the Pacific off Japan

The energy released by capsizing icebergs can be equal to that of small earthquakes — enough to create ocean waves of considerable magnitude. Should such 'glacial tsunamis' be added to the list of future global-warming hazards?

Japan Finds Fish With Taint, Sets New Food Norms
Tokyo/Fukushima: Japan

As Japanese workers pumped out contaminated water into the Pacific Ocean from the quake-hit Fukushima nuclear facility, authorities on Tuesday said radioactive iodine several million times the legal limit was detected in seawater near the plant but insisted that it posed no major health risk.

The plant's operator, Tokyo Electric Power Company (TEPCO), which last week said that contaminated wate

Makes Room For More Lethal Runoff
Tokyo: Tokyo Electric Power Company began dumping over 11,000 tons of radioactive water into the Pacific Ocean from the Fukushima Daiichi nuclear plant on Monday, mostly to make room in storage containers for increasing amounts of far more contaminated runoff.

The water, most of it to be released over two days, contains about 100 times the legal limit of r

Radiation leaked into the sea from Japan's crippled nuclear plant, raising concern that seafood may become tainted, while the site

Summer sea-ice extent in the Arctic has decreased greatly during recent decades. Simulations of twenty-first-century climate suggest that the ice can recover from artificially imposed ice-free summer conditions within a couple of years.
