Water from the Indian Ocean does not reach the South Atlantic Ocean continuously, but in separate packages. These are called Agulhas eddies, after the current along the east coast of Southern Africa where they originate from. Dutch researcher Astrid van Veldhoven characterised the fate of these rapidly rotating, three hundred kilometre wide and five kilometres deep, warm eddies during their journey to the Atlantic Ocean.

A relatively large number of algae grow in the North Sea. These form the basis for a much richer food chain than that found in the Atlantic Ocean. Dutch-sponsored researcher Yann Bozec calculated that coastal seas such as the North Sea remove about three times as much carbon dioxide from the atmosphere than would be expected on the basis of their small surface area.

The measured annual increase in the concentration of carbon dioxide (CO2) in the atmosphere is only 60 percent o

Scientists from nine nations have set sail for the Integrated Ocean Drilling Program (IODP) Tahiti Sea Level Expedition, a research expedition initiated to investigate global sea level rise since the last glacial maximum, approximately 23,000 years ago. For six weeks, aboard the DP HUNTER, the expedition science party will work on the most extensive geological research investigation ever undertaken in a coral reef area. Off the coast of Tahiti, IODP scientists will take samples of fossil cora

Electronic tags broadcasting from the dorsal fins of salmon sharks reveal that these top predators migrate from the glacial waters of Alaska to the warm seas off Hawaii, according to a new study in the journal Science. The salmon shark’s ability to survive such a broad range of thermal conditions is attributed to high levels of specialized proteins that keep its heart muscle cells beating at very low temperatures, say the study’s authors.

Hurricane Erin raced across the North Atlantic and along the eastern seaboard in September 2001. She was used as an experiment for a study to improve hurricane tracking and intensity predictions, allowing meteorologists to provide more accurate and timely warnings to the public. Studies show that temperatures measured at an extremely high altitude collected from a hurricane’s center or eye can provide improved understanding of how hurricanes change intensity.

From this week, researchers worldwide can follow the flow of rivers and height of lakes across the African continent from the comfort of their desks. A new web-based demonstration launched to coincide with this week’s TIGER Workshop makes Envisat-derived altimetry data for African inland water freely available in near-real time.

Envisat’s Radar Altimeter-2 (RA-2) sensor fires around 1800 radar pulses a second down to the surface of the Earth, then measures very precisely ho
