The ocean's smallest swimming animals, such as jellyfish, can have a huge impact on large-scale ocean mixing, researchers have discovered.
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.
A study published Monday reported that fish have lost half their average body mass and smaller species are making up a larger proportion of European fish stocks as a result of global warming.
Drifting across the worldâ€™s oceans are a group of unicellular marine microorganisms that are not only a crucial source of food for other marine life
Southampton scientists have demonstrated an unexpected role of iron in regulating biological production in the high-latitude North Atlantic. Their findings have important implications for our understanding of ocean-climate interactions.
The blooming of toxic algae in the oceans and lakes is a familiar health risk and causes problems every summer, leading to increased costs for water cleaning, water consumption and the tourist industry.
Changes in ocean chemistry â€” a consequence of increased carbon dioxide (CO2) emissions from human industrial activity â€” could cause U.S.

Researchers have conducted the first global analysis of the health and productivity of ocean plants using a unique signal detected by NASA's Aqua satellite.
WASHINGTON, May 28 /PRNewswire-USNewswire/ -- Researchers have conducted the first global analysis of the health and productivity of ocean plants using a unique signal detected by NASA's Aqua satellite. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) Ocean scientists can now remotely measure the amount of fluorescent red light emitted by phytoplankton and assess how efficiently these microscopic plants turn sunlight and nutrients into food through photosynthesis.
The Mediterranean feather star is a filter feeder that obtains food by straining suspended matter and food particles from water. The star has a stalk that has up to forty tendrils, (threadlike organs) which help the star cling to hard surfaces. The “body” of the star is called a calyx and is shaped like a small cup. This calyx is surrounded by feathery pinnules bearing arms. These arms are quite unique in the fact that they can regenerate if one should get broken off; these arms extend to...
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...
The White-spotted jellyfish is also known as the Australian spotted jellyfish (Phyllorhiza punctata). The jellyfish feeds primarily on assorted snail species and thrives in the southwestern Pacific. The bell of the White-spotted jellyfish averages 17-19 inches in diameter but there had been a maximum reported size of 24 inches. However, on Sunset Beach in North Carolina in October, 2007, a White-spotted jellyfish was found on the shore measuring in at 28 inches, perhaps the largest to...
The Tarakihi or Jackass morwong, Nemadactylus macropterus, is a morwong of the genus Nemadactylus found off the coast of southern Australia, the Atlantic coast of South America, and all around New Zealand to depths of about 1312.34 ft (400 m). Its length is between 11.81 and 23.62 in (30 and 60 cm). The Tarakihi is similar to the Porae but with a silver body color and a distinctive black saddle immediately behind the head. Their diet is similar to that of the Porae but also with a wide...
