U.S. scientists say they've uncovered clues about the bioluminescent process used by marine fireworms that produce a green glow often seen in tropical seas. Scripps Institution of Oceanography researchers at the University of California-San Diego led by Dimitri Deheyn and Michael Latz said the fireworms use bioluminescence to attract suitors in an undersea mating ritual and might also use the light as a defensive measure. This is another step toward understanding the biology of the...

Many longtime sailors have been mesmerized by the dazzling displays of green light often seen below the ocean surface in tropical seas. Now researchers at Scripps Institution of Oceanography at UC San Diego have uncovered key clues about the bioluminescent worms that produce the green glow and the biological mechanisms behind their light production.Marine fireworms use bioluminescence to attract suitors in an undersea mating ritual. Research conducted by Scripps marine biologists Dimitri...

WASHINGTON, March 9 /PRNewswire-USNewswire/ -- The Pew Environment Group today called upon the Mid-Atlantic Fishery Management Council to diligently implement important new federal requirements designed to prevent overfishing and rebuild depleted fish populations. The council is currently developing plans to apply the new federal rules, which became effective on February 17, 2009. These rules correspond to 2006 congressional amendments to the Magnuson-Stevens Act, the nation's primary law...

Snapshots trace shrinking 'trophy fish' over a generation of sport fishing A unique study by a scientist at Scripps Institution of Oceanography at UC San Diego has provided fresh evidence of fishing's impact on marine ecosystems. Scripps Oceanography graduate student researcher Loren McClenachan accessed archival photographs spanning more than five decades to analyze and calculate a drastic decline of so-called "trophy fish" caught around coral reefs surrounding Key West, Florida. In a paper...

Science Article Weighs in on International Whaling Commission Debate WASHINGTON, Feb. 12 /PRNewswire-USNewswire/ -- Culling whales will not increase fisheries catches in tropical waters, according to a new paper supported by the Lenfest Ocean Program and published today in the journal Science. For years, Japan has argued that reducing the number of baleen whales in the oceans would improve fisheries because whales eat fish that are caught for human consumption. The study published today...

HILO, Hawaii -- New technology deployed on airplanes is helping scientists quantify landscape-scale changes occurring to Big Island tropical forests from non-native plants and other environmental factors that affect carbon sequestration. U.S. Forest Service and Carnegie Institution scientists involved in the research published their findings this month in the journal Ecosystems and hope it will help other researchers racing to assess threats to tropical forests around the world. "Our...

WASHINGTON, Jan. 15 /PRNewswire-USNewswire/ -- Lee Crockett, director of Federal Fisheries Policy at the Pew Environment Group, today issued the following statement in response to the National Marine Fisheries Service finalizing its annual catch limit rule "This is an important step toward ending overfishing. This rule establishes a good framework for creating annual catch limits based on sound science to end overfishing and help rebuild struggling fish populations. It also requires that...

CAPE TOWN, South Africa, Dec. 1 /PRNewswire-USNewswire/ -- "We kill carelessly," Nobel Laureate Archbishop Emeritus Desmond Tutu said last week as he spoke in support of a global campaign to stop whaling by the International Fund for Animal Welfare (IFAW - www.ifaw.org ). Tutu launched Sacred Ocean - Global Voices Against the Cruelty of Whaling in Cape Town with a speech that made an analogy that compared rape and murder, with the killing of whales. "Are we surprised that we have lost a...

A recent study has found that the Southern Ocean has proved more resilient to global warming than previously thought and remains a major store of mankind's planet-warming carbon dioxide. Oceans act as a brake on climate change by absorbing large portions of the extra CO2 released by mankind through burning fossil fuels or deforestation and experts say the Southern Ocean is the largest of these "carbon sinks." Researchers in the past have suggested the vast ocean between Australia and...

Conservationists say living reef aquariums may be endangering Florida's coral reefs. The Florida Fish and Wildlife Conservation Commission said the use of crabs, snails and other invertebrates in high-end aquariums could upset the ecology of Florida's reefs, the South Florida Sun-Sentinel reported Monday. There has been a change in consumer demand, biologist Jessica McCawley told the newspaper. People used to just keep a fish in a tank with some dead coral. They want invertebrates now,...

Ocean Analysis for November 17, 2012
2012-11-17 08:24:58

Point #1: Warm finger- This region inside the area marked number 1, represents a warm finger of the ocean temperatures. What is occurring is that the warmer air is being pushed faster in this region than the surrounding locations giving us this little finger of warmer temps in that region. Point #2: Warm Eddie- This is a region of warmer temps surrounded on all sides by colder water. Eddies are a closed circulation of water in the ocean that has in this case warmer temps around it. These...

Ocean Current Impacts On Weather
2012-07-30 13:25:48

The Peru Current flows from South to North along the western side of South America. This current transports colder air from the south northward towards the equator. This current is responsible for bringing cooler waters off the coast of Peru which is a big reason that they have such high fishing success. However this current can get altered during EL-Nino when the warmer waters of the Pacific are transported west to east and start to replace these colder waters. The Peru current is...
