While readily carried by two people, the 52kg gliders must be handled carefully, particularly at sea.

Glider 008 shows the cold shelf water near Fyllas Bank (left) and as it moved down the continental slope passed the warm Irminger Current water (profles 9-12). Near profiles 21-30 it was twirled by a warm anticyclonic eddy with strong currents (next slide) The horizontal sampling density of the saw-tooth path averages 3 km; ship-borne hydrographic sections have typical sampling density of 50 to 100km

Two Seagliders launched by UW oceanography, 2 Oct 2004 from Nuuk, west Greenland

TOPEX/Poseidon sea surface height anomaly, corresponding to geostrophic upper ocean circulation (minus its time-average): Rossby waves and synoptic scale eddies, equatorial upwelling/zonal jets, eddies marking the paths of the Antarctic Circumpolar Current, Gulf Stream and Kuroshio..and much more .
