Biomass, metabolic activity much lower than at previously explored sites An international oceanographic research expedition to the middle of the South Pacific Gyre "“ a site that is as far from continents as it is possible to go on Earth's surface "“ found so few organisms beneath the seafloor that it may be the least inhabited sediment ever explored for evidence of life. Yet since half of the world's ocean is composed of similar gyres, biomass and metabolic activity may be...

Weak enforcement combined with fishermen facing serious economic hardships are leading to widespread violations of fisheries regulations along the Northeastern United States coast. This pattern of noncompliance threatens the success of new fisheries management measures put in place to protect and restore fish stocks, according to a new study published online this week in the journal Marine Policy.Among their findings, environmental economists Dr. Dennis King of the University of Maryland...

Council Takes Positive First Steps to Establish Annual Catch Limits, Accountability Measures WASHINGTON, June 1 /PRNewswire-USNewswire/ -- The Pew Environment Group today commended the Mid-Atlantic Council on its initial step toward implementing new federal requirements designed to end overfishing and rebuild depleted fish populations through the application of annual catch limits and accountability measures. The 2006 reauthorization of the Magnuson-Stevens Act requires that fishery...

Sites in Hawaii, Fiji and the Philippines show that protecting vulnerable parts of the ocean pays off for business and the environment, marine experts said. Protected sites ultimately provide higher and more sustained income through tourism and controlled fishing than continued exploitation, experts from the International Union for the Conservation of Nature said. Along the western coast of Hawaii, marine sites were placed under protection in 1999 after years of over-harvesting of fish...

Climate change, fishing and commercial shipping top the list of threats to the ocean off the West Coast of the United States. "Every single spot of the ocean along the West Coast," said Ben Halpern, a marine ecologist at the National Center for Ecological Analysis and Synthesis (NCEAS) at the University of California at Santa Barbara, "is affected by 10 to 15 different human activities annually." In a two-year study to document the way humans are affecting the oceans in this region, Halpern...

Proposed bill would delay the rebuilding of depleted fish populations WASHINGTON, April 7 /PRNewswire-USNewswire/ -- The Pew Environment Group and 44 national, regional and state conservation groups today pressed congressional leaders to oppose "The Flexibility in Rebuilding American Fisheries Act of 2009," saying the legislation would allow overexploitation of vulnerable fish populations. This bill is designed to weaken the Magnuson-Stevens Act (MSA), the nation's primary law governing...

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...

Ocean Analysis for November 17, 2012

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...
