In the frame of JERICO-NEXT-TNA (2nd Call) program, ABACUS-4 mission, ESA’s SENTINEL-3 scientific satellite track #713 (for the 24th time since it was launched), flew over SOCIB’s glider, SDEEP04, on 21/Nov/2017 @21utc. This glider, deployed six days earlier, was at that instant sampling at the center of its programmed transect off the Southern coast of Mallorca that, to allow intercomparison and multi-platform sampling, corresponds to a segment of SENTINEL’s track #713. Whilst the satellite covered this segment in less than 3 minutes, SDEEP05 will still take 4-5 days to cover the same over-ground distance.
