    • Temperature profile data from XBT casts along repeat transects in the Pacific Ocean and Indian Ocean for the High Resolution XBT Network by Scripps Institute of Oceanography from 1989 to present

    Metadata Updated: December 1, 2023

    Repeat high resolution expendable Bathythermograph (XBT) transects have been collected along a number of commercial shipping routes spanning the Pacific Ocean, the Drake Passage, and Tasmania to Dumont d'Urville. On each of the transects generally four surveys are conducted per year. Temperature data are usually collected by a scientist on board the vessel using an automatic XBT launcher designed at Scripps Institution of Oceanography (SIO). The launcher holds 6 XBT probes which are pre-programmed to drop at specific locations (using GPS) or times. The XBT probes are Sippican "Deep Blue", which are rated to 760 m depth, but typically return temperature to a depth of around 850 m at ship speeds of 15 to 18 knots. Sequential XBT casts are separated by 30-40 km along track, with closer station spacings of 10 km near boundaries, across the equator and in topographically varying regions. Sampling begins and ends near the 200 m isobath at the coastal endpoints of the tracks.
