					NJ Seal Study – Field Trip
      Introduction
    Stockton Marine Science and
    Environmental Field Station
 Located off of the
  Mullica River
 Mullica River
  empties into the
  Great Bay
 The Great Bay
  empties into the
  Atlantic Ocean
   Designated as the Jacques Cousteau
    National Estuarine Research Reserve
    (JCNERR)
    – NOAA funded program
    – Designated in October of 1997
My Position

   Faculty support

   Facility management

   Direct marine operations
    – Safety program
Boating Safety – year round

   Medical needs – must inform me

   Boarding a boat – carefully

   While underway – suits zipped up

   Getting off the boat

   Questions?
Boating safety – cold weather
 Cold weather, cold water and windy conditions
 More than half of annual boating accident fatalities
  occur in these conditions
 Less boaters on the water = less chance of
  immediate rescue
 Water removes heat from body 25x faster than air
 Survival time in water < 40F can be reduced to
  minutes


        = STAY ON THE BOAT
Your chances of entering the water are very slim,
BUT…

   Slipping while getting off of the boat
    – May or may not be shallow!
    – If only feet get wet, still have problem

   Falling over side while underway
    – Not holding on well
    – Moving around when you are unfamiliar with such activity

   Actual sinking of vessel in open water
    – Catastrophic collision with another boat or large object
    – Flipping vessel in heavy seas or ice
Knowledge, gear, and behavior
   Knowledge – two things against you…

    – Cold Shock
       • Involuntary gasping reflex
       • Increased heart rate and blood pressure = cardiac arrest
       • Loss of consciousness

    – Hypothermia
       •   Decreased body temperature – long exposure
       •   Slower onset than cold shock
       •   Muscle rigidity and loss of manual dexterity
       •   Decreased mental capacity
Gear – immersion work suits

   Mustang survival
    suits
   Provide floatation
   Provide warmth
   Cinch up straps for
    maximum protection
   Must be worn to be
    counted as a PFD
Water temperatures during
your field season = 30F – 55F
    Survival time depends on behavior

 Try to get back on boat
  or land ASAP
 Stay with an overturned
  vessel – do not attempt
  to swim to shore unless
  VERY close (<50m)
 If you cannot get out of
  the water
     –   Cover head if possible
     –   Assume HELP position
     –   Stay with others
     –   Minimize motion
Treatment of Hypothermia
         (http://www.blacklakeny.com/offseasonsafety.html)


   Mild case – (victim shivering but coherent)
    –   Move to warm area
    –   Remove wet clothes
    –   Give warm, sweet drinks: NO alcohol or caffeine
    –   Keep victim warm for several hours

   Moderate case – (shivering may decrease or stop)
    –   Victim may seem irrational
    –   Same treatment but NO drinks
    –   Lye victim down, cover with warm blankets
    –   Seek medical attention ASAP
Hypothermia treatment, cont’d.
   Severe case
    – Shivering may stop, victim may begin to lose consciousness
    – Keep victim prone and immobile
    – Handle gently
    – Cover in dry, warm blankets
    – Stimulate legs and arms gently
    – Cold blood in extremities can return to core and induce
      cardiac arrest
    – Seek medical attention ASAP

   Victim appears dead
    –   Little or no pulse or breathing
    –   Assume victim can be revived
    –   If there is any trace of pulse or breathing, DO NOT give CPR
    –   Medical help is imperative
More on cold weather preparation…
   Dress sensibly
    – Warm clothes, layer
    – Polypropylene long underwear
    – Sock liners, wool inserts
    – Waterproof boots – required
 Eat sensibly the day of the trip
 If you plan on removing survival suit for
  blind work
    – Need additional jacket, waterproof pants
   Bring water to drink
Other important knowledge
   Where you are
    – Travel from Nacote Creek – Mullica River -
      across northern end of Great Bay
    – Seven Islands, Great Bay
    – Nearest road – Rutgers University Field
      Station, end of Great Bay Blvd.

   Communication
    – VHF radio – field station/USCG
    – Cell Phone – boat cell phone has list of
      important numbers
R/V Osprey…
Is there a trip?
 Call 652-4486, or x4486 from campus
 The message will indicate a cancellation
  within one hour of the anticipated trip
 Please call if you are not coming
 Boat leaves the dock at the set time
 Don’t bring along more than you need
652-4486, or x4486 from campus
