Estimates are provided for the sea-surface, 50m, 100m, and 150m. 59626d1f-3796-4995-9333-41c7136c76df In recent years the term 'enhanced greenhouse effect' has become well known in modern society and yet aspects of this possible 'future climate' are poorly understood. The characteristics of the geological record provide a basis to understand this possible future climate through the examination of alternating glacial (cold) and interglacial (warm) stages. Understanding the variability of sea-surface temperature and biological processes in the water column provides insight into general circulation of present and paleo-ocean currents. The core obtained offshore from Sumatra (BAR9043, 104.0316E, 5.82S) highlights an upwelling signal at 14,000 yrs BP that disrupts the warm stratified water column, which was a feature between Marine Isotope Stage (MIS) 3 to present. This upwelling is timed to a regional pattern of an intensified Australasian Monsoon. {"type": "Polygon", "coordinates": [[[104.0, -6.0], [104.5, -6.0], [104.5, -5.5], [104.0, -5.5], [104.0, -6.0]]]} 104.0 104.5 -6.0 -5.5 Oceans | Ocean Temperature | Sea Surface Temperature Oceans | Ocean Temperature | Water Temperature age_of_core depth sea_surface_temperature ANU_Spooner_BAR9403_4_data.xls documentDigital XLS aodn:bluenet_datasets_leeuwin_current documentDigital Core data - Leeuwin Current WMS Unnamed resource documentDigital HTML Unnamed resource documentDigital HTML Unnamed resource documentDigital HTML Unnamed resource documentDigital License Graphic PNG Unnamed resource documentDigital HTML Unnamed resource documentDigital HTML Unnamed resource documentDigital HTML
