AB: The varved sediments accumulating in the Cariaco Basin are widely recognized as containing an incomparable archive of past tropical climate change. These sediments are used to study climate on multiple time scales, and to better determine the relationship and phasing between high latitude and low latitude climate change. The Cariaco Basin Ocean Time Series Program was started as a joint US-Venezuelan initiative in 1995 in an effort to link modern processes with this sedimentary record of climate change. The primary scientific objective of the time series is to better understand the interrelationships amongst climate, hydrography, primary production and sediment fluxes, and how signals of changes in these processes are preserved in seafloor sediments. Specifically, our monthly monitoring of water column properties and the continuous collection of sediment flux observations since the inception of the time series provide an ideal opportunity for refining and calibrating climate proxies, for use both in Cariaco Basin and elsewhere. In this talk we will review the accomplishments of the Cariaco Basin Ocean Time Series and the opportunities that exist for collaborations.
