Latest Trichodesmium Stories
The nutrient known as “fixed” nitrogen, which is essential to the health of the ocean, is controlled by the cyclic wobble of the Earth on its axis.
A new study from the University of Southern California reveals climate change may be weeding out the bacteria that form the base of the ocean’s food chain by selecting certain strains for survival.
Marine scientists long believed that a microbe called Trichodesmium, a member of a group called the cyanobacteria, reigned over the ocean's nitrogen budget.
Scientists including researchers from the National Oceanography Centre, Southampton and the University of Essex have discovered that interactions between iron supply, transported through the atmosphere from deserts, and large-scale oceanic circulation control the availability of a crucial nutrient, nitrogen, in the Atlantic.
Trichodesmium has important role in nitrogen cycle and carbon sequestration.
Observations made by Southampton scientists help understand the massive blooms of microscopic marine algae â€“ phytoplankton â€“ in the seas around Madagascar and its effect on the biogeochemistry of the southwest Indian Ocean.
A USC oceanographer's long-term study shows that the marine food chain depends in large part on atmospheric nitrogen. The finding also demonstrates the oceans' massive absorption of greenhouse gas.
