What constitutes fish food is a matter of debate. A high-profile study a few years ago suggested that fish get almost 50 percent of their carbon from trees and leaves, evidence for a very close link between the terrestrial and aquatic ecosystems. But new research from the University of Washington shows this is not likely to be true. Algae provide a much richer diet for fish and other aquatic life, according to research published this week in the Proceedings of the National Academy of...

Drifters designed to provide new knowledge about marine protected areas, harmful algal blooms, oil spills In an effort to plug gaps in knowledge about key ocean processes, the National Science Foundation (NSF)'s division of ocean sciences has awarded nearly $1 million to scientists at the Scripps Institution of Oceanography in La Jolla, Calif. The Scripps marine scientists will develop a new breed of ocean-probing instruments. Jules Jaffe and Peter Franks will spearhead an effort to design...

A chemical culprit responsible for the rapid, mysterious death of phytoplankton in the North Atlantic Ocean has been found by collaborating scientists at Rutgers University and the Woods Hole Oceanographic Institution (WHOI).  This same chemical may hold unexpected promise in cancer research. The team discovered a previously unknown lipid, or fatty compound, in a virus that has been attacking and killing Emiliania huxleyi, a phytoplankton that plays a major role in the global carbon...

Nutrients in the Atlantic Large-scale distributions of two important nutrient pools "“ dissolved organic nitrogen and dissolved organic phosphorus (DON and DOP) have been systematically mapped for the first time over the Atlantic Ocean in a study led by Dr Sinhue Torres-Valdes of the National Oceanography Centre, Southampton. The findings have important implications for understanding nitrogen and phosphorus biogeochemical cycles and the biological carbon pump in the Atlantic Ocean. Tiny...

Eutrophication of the seas may have an impact on genetic variation in algae, research at the University of Gothenburg shows. Phytoplankton provide the basis for the whole marine food chain. These microscopic organisms are common in coastal areas, all the way from the polar regions to the Equator, and multiply through cell division. If cells are present in the water mass in large numbers an algal blood develops - a recurrent problem in Swedish seas and along Swedish coasts. Causes of algal...

Scientists work to explain why massive "dead zones" have been invading the Pacific Northwest's near-shore waters since 2002 Yet another ecological scourge may earn a place on the ever-lengthening list of problems potentially caused by climate change: the formation of some so-called "dead zones""”huge expanses of ocean that lose virtually all of their marine life at depth during the summer. Possible connections between climate change and the relatively recent formation of dead zones in...

Trichodesmium has important role in nitrogen cycle and carbon sequestration A new study of microscopic marine microbes, called phytoplankton, by researchers at Woods Hole Oceanographic Institution (WHOI) and the University of South Carolina has solved a ten-year-old mystery about the source of an essential nutrient in the ocean. Roughly a decade ago scientists discovered a rare form of organic phosphorus in marine organic matter. Not only were the researchers surprised to find this form of...

Observations made by Southampton scientists help understand the massive blooms of microscopic marine algae "“ phytoplankton "“ in the seas around Madagascar and its effect on the biogeochemistry of the southwest Indian Ocean.The observations were made by researchers based at the National Oceanography Center, Southampton (NOCS) during a 2005 hydrographic survey south and east of Madagascar while aboard the royal research ship RRS Discovery. The fully analyzed results are published...

Amongst the smallest micro-algae belonging to the group of so-called haptophytes(1) , considerable diversity has recently been demonstrated in our oceans. Scientists from the Marine Biology Laboratory in Roscoff and Oceanographic Laboratory in Villefranche sur Mer (UPMC/CNRS), in collaboration with Rutgers University (USA) and University of Ottawa (Canada), have shown that these photosynthetic microorganisms, highly diversified and extremely abundant, are some of the most important producers...

For a long time scientists have observed the biological consequences of global climate change. One of the most famous symptoms is the shift of habitats from the equator further north or further south. More recent studies show that not only the habitats but also the size of organisms is affected. Dr. Martin Daufresne of the HYAX Lake Ecosystem Laboratory in Aix-en-Provence, France, as well as Prof. Ulrich Sommer and Dr. Kathrin Lengfellner of the Leibniz-Institute of Marine Sciences...

Image Caption: Chilean Sea Urchin, Loxechinus albus. Credit: Dentren/Wikipedia (CC BY-SA 3.0) The Chilean sea urchin (Loxechinus albus) is a species that can be found along the coastlines of Chile and Peru. It is typically found in shallow waters at or below the tide level, buried in sand or lying just on top of it. This species is often associated with Macrocystis pyrifera, a type of kelp. It is most often found in more open spaces. The Chilean sea urchin can reach an average width of...
