For hundrede \u00e5r siden, den 15. april 1912, st\u00f8dte RMS Titanic p\u00e5 et isbjerg og sank under en overfart over det nordlige Atlanterhav, hvilket kostede over 1 500 passagerer og bes\u00e6tningsmedlemmer livet. I dag krydser tusindvis af skibe den samme rute uden tab af menneskeliv \u2013 og det er takket v\u00e6re satellitterne.<\/p>\n<\/div>\n

Frederick Fleet havde til opgave at st\u00e5 vagt p\u00e5 Titanic natten til den 14. april 1912. De oplysninger om isforholdene, som Frederick leverede, var de eneste oplysninger, kaptajn Edward John Smith havde til r\u00e5dighed til at navigere skibet gennem disse farlige farvande.<\/p>\n

En af de vigtigste konsekvenser af Titanic-katastrofen var forbedringen af sikkerheden til s\u00f8s, herunder indf\u00f8relsen af den internationale konvention om sikkerhed for menneskeliv til s\u00f8s og den internationale ispatrulje (IIP).<\/p>\n

Isvagtens opgave er at overv\u00e5ge isbjerge og afgr\u00e6nse et isbjergsfareomr\u00e5de. Der kan til enhver tid v\u00e6re tusindvis af isbjerge i de arktiske farvande. Ispatruljens udfordring best\u00e5r i at fastsl\u00e5, hvor mange isbjerge der vil drive sydp\u00e5 mod skibsruterne. Indtil videre har intet skib, der har fulgt Ispatruljens offentliggjorte \u2018isbjerggr\u00e6nse\u2019, kollideret med et isbjerg!<\/p>\n

I begyndelsen benyttede Isvagten skibe til at udf\u00f8re rutinem\u00e6ssige ispatruljer, men skiftede efter Anden Verdenskrig til luftoverv\u00e5gning. I dag er luftoverv\u00e5gning den prim\u00e6re metode, men IIP har til hensigt at erstatte de dyre isflyvninger med satellitobservationer.<\/p>\n

I dag bruger Isvagten satellitbaserede radarobservationer som supplement til luftbaserede observationer. Radarer p\u00e5 satellitter er s\u00e6rdeles velegnede til overv\u00e5gning af isbjerge, da de kan tage billeder gennem skyer og i m\u00f8rke.<\/p>\n

Sentinel-1, der skal opsendes i 2013, vil markant \u00f8ge tilg\u00e6ngeligheden af radardata og hj\u00e6lpe ispatruljen med at undg\u00e5 katastrofer som den, der ramte det hundrede \u00e5r gamle Titanic.<\/p>","protected":false},"excerpt":{"rendered":"
