Results of the first 6-month effort include 1 Formulation of a plan, acquisition of hardware, and development of programs to test and improve alternate transfer function techniques 2 compilation of pollen data for 800 modern sites in eastern U.S. 3 confirmation of a 60,000-year old sea-level high-stand on Barbados 4 confirmation in deep-sea core records of climatic cycles of 180,380, and 2500-year periods 5 documentation of a 70-meter sea- level low following within 10,000 years of the last interglacial thermal maximum 6 discovery of a set of deep-sea cores off North Carolina containing evidence of a shifting Gulf Stream during the last 10,000 years 7 time-series analyses of a million-year climatic record from the Pacific indicating that changes in the earths solar orbit are in fact important influences controlling global climate change 8 finalization of plans for the first ARPA-CLIMAP global Atmosphere-Ocean Modelling Experiment, which will test the ability of the Mintz-Arakawa general circulation model to explain global climatic patterns 18, 000 YBP, during a maximum of the last ice age.
