Geostrophic wind over Cape York Peninsula and pressure jumps around the Gulf of Carpentaria
Pressure jumps, almost certainly due to interaction of opposing sea-breeze gravity currents, are very common in the nocturnal atmosphere of western Cape York Peninsula and the Gulf of Carpentaria in October. Most come from the east-northeast
-2m. Amino-acid ratios, archaeology, pollen and lithostratigraphy suggest that the sea later jumped to about +16m. The combination of the cooling and the large jump points to an East Antarctic ice surge, at 95 kyr BP.
