Dead Zone in Gulf Linked to Oil Oxygen-starved waters that have persisted for more than a month in the Gulf of Mexico are likely due to the BP oil spill, researchers say. Fri Jul 9, 2010 08:21 AM ET The researchers measured low oxygen levels along the entire 40-mile stretch they sampled around Dauphin Island, Ala., from about 40 miles offshore to within a mile or two of the shoreline. The bottom layer of water was oxygen-depleted at depths of about 30 feet close to shore to 100 feet further out, along the continental shelf -- a rim of shallow water tracing the coast from Mississippi to Florida. news.discovery.com/earth/gulf-mexico-dead-zone-oil-spill.html

Huge oil plumes create massive swath of destruction Enormous plumes of oil are killing billions of organisms, rippling throughout the entire Gulf of Mexico marine ecosystem. Tue, Jun 01 2010 at 1:13 PM EST Scientists agree that every fish and shellfish in contact with the oil is probably dead. We are now on day 42 of the spill, and billions of organisms have perished. The longer this spill continues, the more likelihood that this number will turn into trillions of dead organisms. The Gulf of Mexico is vast, spanning 600,000 square miles and reaching more than 14,000 feet at its deepest point. www.mnn.com/earth-matters/climate-change/stories/huge-oil-plumes-create-massive-swath-of-destruction-0

On the Surface, Gulf Oil Spill Is Vanishing Fast; Concerns Stay July 27, 2010 Two preliminary government reports on that issue have found concentrations of toxic compounds in the deep sea to be low, but the reports left many questions, especially regarding an apparent decline in oxygen levels in the water. www.nytimes.com/2010/07/28/us/28spill.html?_r=1

WATER SAMPLING CONFIRMS LOW OXYGEN LEVELS IN DELAWARE BAY; DEP WORKING TO SPEED REMOVAL OF DEAD FISH FROM BEACHES * UPDATED RELEASE * WATER SAMPLING CONFIRMS LOW OXYGEN LEVELS IN DELAWARE BAY; DEP WORKING TO SPEED REMOVAL OF DEAD FISH FROM BEACHES (10/P82) TRENTON - The Department of Environmental Protection this afternoon received new water sampling results that strongly suggest low oxygen levels were behind the massive die-off of menhaden in Delaware Bay. Three of four samples taken today showed dissolved oxygen levels below 5 micrograms per liter. Any level below that is considered biologically stressed. The fourth sample was just above the threshold. The lowest reading - 3.4 micrograms per liter - was recorded at Pierce’s Point in Middle Township, one of the areas hard hit by washed-up fish. www.nj.gov/dep/newsrel/2010/10_0082.htm______________________ Hundreds of Thousands of DEAD FISH on NEW JERSEY SHORE AUG 12 2010 www.youtube.com/watch?v=ag0oQm0dhXs _______________________ NJ. DEP chief says Gulf oil spill no threat to Jersey Shore beaches this summer - Monday, 14 June 2010 16:56 In his testimony, Martin said the unlikely sequence of events that would be required for oil from the Gulf to reach New Jersey an eddy would have to break off from the Gulf Stream off North Carolina, which is not typical. He said even then such as eddy would have to make landfall along the coast of Massachusetts or eastern Long Island – north of New Jersey – to reach the state's coastline because the current along the New Jersey coast moves southward. www.newjerseynewsroom.com/science-updates/nj-dep-chief-says-gulf-oil-spill-no-threat-to-jersey-shore-beaches-this-summer

Mississippi (tens of thousands of dead fish floating in Biloxi waters Tuesday Aug 3). --->> silver Menhaden, or pogey fish1000's of Dead fish along Mississippi Gulf Coast il.youtube.com/watch?v=A8YAnfedzBs--->> silver Menhaden and redfish - 2 sq mile areaNew Jersey, Delaware Bay, maybe Aug 11. --->> juvenile menhaden_________________________________ Diet Menhaden are omnivorous filter feeders, feeding by straining food particles from water. They travel in large, slow moving, and tightly packed schools with open mouths. Filter feeders typically take into their open mouths "materials in the same proportions as they occur in ambient waters".[3] Menhaden primarily eat phytoplankton (microscopic plants); although, since they are omnivorous, they take in a small portion of zooplankton (microscopic animals). Even though most other related fish (in the family Clupeidae) eat zooplankton, "Menhaden primarily consume phytoplankton, that is, algae and other drifting bits of vegetable matter. The ecological significance of this difference can hardly be overstated."[4] Commercial importance Menhaden are not used for human consumption. They die quickly, and they spoil rapidly if not immediately gutted and iced. They are also very bony and smelly. However, menhaden are the primary source of fishmeal, used as food for poultry and pen-raised fish, such as salmon. Atlantic menhaden are an important link between plankton and upper level predators. Because of their filter feeding abilities, “menhaden consume and redistribute a significant amount of energy within and between Chesapeake Bay and other estuaries, and the coastal ocean.”[5] Because they play this role, and their abundance, menhaden are an invaluable prey species for many predatory fish, such as striped bass, bluefish, mackerel, flounder, tuna, Drum_(fish), and sharks. They are also a very important food source for many birds, including egrets, ospreys, seagulls, northern gannets, pelicans, and herons. en.wikipedia.org/wiki/Menhaden www.oceanassoc.com/Photos&Information.html

Dead fish ashore in Massachusetts - Aug 9 www.youtube.com/watch?v=ZfrPfBvH1O0--->> silver Menhaden, or pogey fish_____________________ Fairhaven, MA: Dead Fish Wash Ashore In Thousands, Lack Of Oxygen In Warm Waters To Blame Posted: 08-10-10 02:11 PM On Monday, vacationing beach residents awoke to a foul smell when thousands of dead fish washed ashore on a small island on the east side of Fairhaven, Massachusetts, CNN reports. Marine fisheries explained that the fish were killed due to a lack of oxygen caused by warm waters. All of the fish were Menhaden, which are especially sensitive to such changes, and they may have been dead for days prior to washing up on the beach. www.huffingtonpost.com/2010/08/10/fairhaven-ma-dead-fish-wa_n_677140.html

Gulf of Mexico oil spill recovery to focus on wetlands, EPA administrator says Published: Friday, August 05, 2011, 5:40 PM Garret Graves, who chairs the Coastal Protection and Restoration Authority of Louisiana, told the conference that his state has 40 percent of the coastal marshlands in the continental U.S., which are not only habitat for a number of species, but key filters for water flowing downstream from the Mississippi. Channelization of the river beginning in the 1930s led to the losses, which now amount to an area the size of Manhattan every year, he said. Wetlands loss and the Gulf's growing low-oxygen dead zone are linked because of that lost filtering ability, Jackson said. www.nola.com/news/gulf-oil-spill/index.ssf/2011/08/gulf_of_mexico_oil_spill_recov.html

The Most Important Fish in America is in Jeopardy October 7, 2011 Menhaden are the most underrated, yet most essential fish of the Atlantic and Gulf waters. But a history of overfishing and human interference will soon leave them as a distant memory. Safe fishing targets for Menhaden have been exceeded every single year but one since 1955. In fact, overfishing of Menhaden dates all the way back to 1879. Millions of tons of Menhaden were used as fertilizers, oil and animal feed until all of them, on the coasts of New York, Connecticut and Maine, were completely gone. www.care2.com/causes/the-most-important-fish-in-america-is-in-jeopardy.html

NOAA, partners predict possible record-setting dead zone for Gulf of Mexico Also anticipating smaller hypoxia levels than in past in Chesapeake Bay June 18, 2013 NOAA-supported modelers at the University of Michigan, Louisiana State University, and the Louisiana Universities Marine Consortium are forecasting that this year’s Gulf of Mexico hypoxic “dead” zone will be between 7,286 and 8,561 square miles which could place it among the ten largest recorded. That would range from an area the size of Connecticut, Rhode Island and the District of Columbia combined on the low end to the New Jersey on the upper end. The high estimate would exceed the largest ever reported 8,481 square miles in 2002 . www.noaanews.noaa.gov/stories2013/20130618_deadzone.html
