    2010-2013 Cetacean Unusual Mortality Event in Northern Gulf of Mexico


    Map of Strandings

    Summary

    Under the Marine Mammal Protection Act of 1972 (as amended), an Unusual Mortality Event (UME) has been declared for dolphins and whales (cetaceans) in the northern Gulf of Mexico (Texas/ Louisiana border through Franklin County, FL) from February 2010 through the present.
    These numbers are preliminary and may be subject to change. As of January 13, 2013, the UME involves 830 Cetacean "strandings" in the Northern Gulf of Mexico (5% stranded alive and 95% stranded dead). Of these:

    Brucella bacteria

    In addition to investigating all other potential causes, scientists are investigating what role Brucella may have in the Unusual Mortality Event.
    Since our original finding of Brucella in 5 stranded dolphins from Louisiana, scientists have been concentrating testing on cases that show pathological changes consistent with the fetal pneumonia or adult meningitis identified in the first 5 cases. Here are our results showing the total number of Brucella cases identified so far. We update these numbers as new results are available.

    Cetacean Unusual Mortality Event in Northern Gulf of Mexico (2010-present)

    Summary

    Under the Marine Mammal Protection Act of 1972 (as amended), an Unusual Mortality Event (UME) has been declared for dolphins and whales (cetaceans) in the northern Gulf of Mexico (Texas/Louisiana border through Franklin County, FL) from February 2010 through the present.
    These numbers are preliminary and may be subject to change. As of December 14, 2014, the UME involves 1,295 Cetacean "strandings" in the Northern Gulf of Mexico (6% stranded alive and 94% stranded dead). Of these:
    114 cetaceans stranded prior to the response phase for the oil spill February 1, 2010- April 29, 2010
    121 cetaceans stranded or were reported dead offshore during the initial response phase to the oil spill April 30, 2010- November 2, 2010
    1,060 cetaceans stranded* after the initial response phase ended November 3, 2010 -
    December 14, 2014**
    *This number includes 9 dolphins that were killed incidental to fish related scientific data collection and 1 dolphin killed incidental to trawl relocation for a dredging project.

    **The initial response phase ended for all four states on November 2, 2010. Response re-opened for eastern and central Louisiana on December 3, 2010 and closed again on May 25, 2011.


    Brucella bacteria

    In addition to investigating all other potential causes, scientists are investigating what role Brucella may have in the Unusual Mortality Event.
    Since our original finding of Brucella in 5 stranded dolphins from Louisiana, scientists have been concentrating testing on cases that show pathological changes consistent with the fetal pneumonia or adult meningitis identified in the first 5 cases. Here are our results showing the total number of Brucellacases identified so far. We update these numbers as new results are available.

    Map

    The following map displays stranding locations from the 2010-2014 Cetacean Unusual Mortality Event in the Northern Gulf of Mexico. Bottlenose dolphin stranding locations are represented by circle symbols, while stranding locations for all other cetacean species are represented by square symbols. Symbols containing a black dot indicate that the reported actual/estimated length of the stranded cetacean was less than 115 cm. Symbols that are colored pink, represent the most recently reported data. Dropdown boxes located above the map allow filtering of the mapped locations and clicking on a mapped location will open an information window containing data associated with the selected stranding.
