Who Keeps Track of the Squids
November
25, 2006: In the U.S. Navy, the METOC (meteorological and oceanographic)
community is an odd bird. Everyone knows what the meteorology side does
(predicts the weather), but the oceanography side is usually not understood at
all. Aside from providing information on currents, water peculiarities (e.g.,
thermal layers, salinity, etc.), the oceanographers also keep track of marine
life. Aside from environmental issues, marine life can affect sonars in
interesting ways and offer other challenges. Ignoring the METOC officer can be
risky. A few years ago a carrier passing through the Straights of Magellan was
almost incapacitated by enormous schools of squid. These sea creatures were
sucked into the water intakes in large quantities, nearly clogging them, which
could have led to engine problems for want of coolant. Turned out the skipper
had not consulted his staff METOC officer. The captain had passed the straits
before with no problems, but didn't realize there were seasonal patterns to
marine life that only the METOC was aware of. Only METOC keeps track of squid
migrations.
