    <skos:definition xml:lang="en">SCICEX is a 5 year program (1995-1999) in which the Navy has madeavailable a Sturgeon-class, nuclear powered, attack submarine forunclassified science cruises to the Arctic Ocean. Beginning with atest cruise in 1993, civilian scientists together with Navy personnelhave collected a variety of information on the geology, physics,chemistry and biology of this critical region. The unmatched mobilityof submarines in ice covered oceans has allowed data to be collectedfrom over 100,000 miles of shiptrack in the Arctic providing samplesfrom some regions that have never before been visited.(adaopted from the SCICEX Program Page)The following submaries have been used in SCICEX:- SCICEX/93 USS Pargo- SCICEX/95 USS Cavalla- SCICEX/96 USS Pogy- SCICEX/97 USS Archerfish- SCICEX/98 USS Hawkbill- SCICEX/99 USS HawkbillFor more information, data, and research results, see the SCICEXProgram page at:&apos;http://www.ldeo.columbia.edu/SCICEX/&apos;</skos:definition>
