New research tracking the movement of dredged sediment around Liverpool Bay could save millions of pounds, according to scientists at the National Oceanography Centre in Liverpool. Each year, sediment has to be dredged from the port and deposited elsewhere to maintain access for commercial vessels. But according to the new study, the dredged material appears back in the port again within just a few weeks of its removal, carried by sea currents. "There are two competing sediments coming...

Scientists Say Ocean Nutrients A Key Component Of Future Change
2013-04-10 12:21:16

National Oceanography Centre, Southampton (UK) Variations in nutrient availability in the world's oceans could be a vital component of future environmental change, according to a multi-author review paper involving the National Oceanography Centre, Southampton (NOCS). The paper, published this month in Nature Geoscience, reviews what we know about ocean nutrient patterns and interactions, and how they might be influenced by future climate change and other man-made factors. The authors...

Study Calculates Arctic Ocean Nutrient Budget

National Oceanography Centre, Southampton (UK) The first study of its kind to calculate the amount of nutrients entering and leaving the Arctic Ocean has been carried out by scientists based at the National Oceanography Centre, Southampton. Their results, which are published this month in the Journal of Geophysical Research, show that there is a mismatch between what goes into the Arctic Ocean and what comes out. This is the first study to look at the transport of dissolved inorganic...

Most Pressing Marine Science Questions Addressed
2012-12-10 13:45:17

National Oceanography Centre Southampton The most pressing issues that UK marine science needs to address over the next two decades are the subject of a prospectus published as a themed issue of the Philosophical Transactions of the Royal Society A last month. The volume is co-edited and carries contributions by scientists based at the National Oceanography Centre Southampton (NOCS). Human-induced changes in ocean processes are already being observed, and are projected to intensify as...

Reliable measurements of the air-sea flux of carbon dioxide "“ an important greenhouse gas "“ are needed for a better understanding of the impact of ocean-atmosphere interactions on climate. A new method developed by researchers at the National Oceanography Centre, Southampton (NOCS) working in collaboration with colleagues at the Bjerknes Center for Climate Research (Bergen, Norway) promises to make this task considerably easier. Infrared gas sensors measure carbon dioxide based...

The impact on levels of carbon dioxide in the Earth's atmosphere by the decaying remains of a group of marine creatures that includes starfish and sea urchin has been significantly underestimated. "Climate models must take this carbon sink into account," says Mario Lebrato, lead author of the study. The work was done when he was at the National Oceanography Centre, Southampton (NOCS) and affiliated with the University of Southampton's School of Ocean and Earth Science (SOES); he is now at the...

Summer weather and UK marine life A recent scientific conference has provided new evidence for the effects of unseasonal summer storms on a variety of spectacular marine life, including deadly jellyfish, basking sharks and oceanic seabirds. The third annual 'South West Marine Ecosystems' meeting, held in Plymouth in December 2009, brought together 40 representatives from the scientific, conservation, fishing and eco-tourism sectors. The aim was to discuss impacts of environmental change and...

The analysis of microfossils found in ocean sediment cores is illuminating the environmental conditions that prevailed at high latitudes during a critical period of Earth history. Around 55 million years ago at the beginning of the Eocene epoch, the Earth's poles are believed to have been free of ice. But by the early Oligocene around 25 million years later, ice sheets covered Antarctica and continental ice had developed on Greenland. "This change from greenhouse to icehouse conditions...

Sally Hall, a PhD student at the University of Southampton's School of Ocean and Earth Science (SOES) at the National Oceanography Centre, Southampton (NOCS) has formally described four new species of king crab, all from the deep sea. Hall discovered the new species in the Smithsonian Collections of the National Museum of Natural History in Washington. Explaining the significance of the find, she said: "King crabs include some of the largest crustaceans currently inhabiting Earth and are...

Oceanic core complexes Long-term variations in volcanism help explain the birth, evolution and death of striking geological features called oceanic core complexes on the ocean floor, says geologist Dr Bram Murton of the National Oceanography Centre, Southampton. Oceanic core complexes are associated with faults along slow-spreading mid-ocean ridges. They are large elevated massifs with flat or gently curved upper surfaces and prominent corrugations called 'megamullions'. Uplifting during...
