#1: Title: Oceanic Time-series Measurements:
Assessment of the Past and Planning for the Future Starting with the first oceanic time-series program, Hydrostation S, and followed by the BATS, HOT, CARIACO and other time-series studies, our understanding of the complex biogeochemical processes that occur in the surface ocean has increased exponentially. With 12+ years of biogeochemical data collected at BATS and HOT, questions related to the longer-term oceanic response to climate variability are now being robustly tested. The goals of this special session are two-fold. First, to highlight the past temporal dynamics of ocean biogeochemical processes, and second to emphasize how these time-series measurements have changed our understanding of oceanic systems and will impact future science programs. To this end, we encourage the submission of all papers exploring temporal dynamics of oceanic biogeochemistry, including new insights into the functioning of oceanic ecosystems. Conveners: Michael W.

The session is designed to bring together recent advances in the study of biogenic fluxes in present-day and past environments and conditions. The hope is that studies of fluxes in the modern ocean can provide insights into the interpretation of the sediment record that could not be achieved solely through paleoceanographic studies. Conversely, studies of past fluxes provide a temporal context and an assessment of fluxes under forcing conditions different than the present which may provide insights into controling mechanisms that would not be evident from modern studies alone. The formal description of the session and contact information follow. We ask that those submitting abstracts, send copies to Roger and I so that we may monitor the response. Thank you, __________________________________________________________________

Paleoceanographic studies are currently limited by uncertainties in our understanding of the linkage between ocean processes and the preservation of tracers and proxies in the geologic record while a lack of temporal context limits our understanding of current fluxes. The PAGES - JGOFS Task Team seeks to bring together present-day and paleoceanographic studies of biogenic fluxes and processes. The purpose of this session is to report new insights of modern biogeochemical processes gained through recent flux studies and of the carbon cycle under forcing conditions different from those prevailing today which may highlight fundamental processes that may be missed by studying the modern ocean alone.
