and the terrestrial biosphere uptake<BR>has increased since ~1990 with major
implications for our understanding of<BR>the global carbon cycle and ability to
predict the future fate of<BR>anthropogenic carbon.<BR><BR>Dr. Jorge L.
Sarmiento is a Professor of Geosciences at Princeton<BR>University. Dr.
Sarmiento's primary research interests are in the oceanic<BR>cycles of
climatically important chemicals such as carbon dioxide, and in<BR>the use of
chemical tracers to study ocean circulation. Ongoing research<BR>includes the
use of ocean general circulation models to estimate uptake of<BR>anthropogenic
CO2, and the use of atmospheric general circulation models<BR>constrained with
atmospheric CO2 observations to estimate transport of CO2<BR>in the atmosphere.
He is working in conjunction with ocean biologists to<BR>develop ecosystem
models for predicting photosynthetic uptake of carbon in<BR>the surface ocean,
as well as remineralization of organic matter in the<BR>deep ocean. Dr.
Sarmiento has participated in the scientific planning and<BR>execution of many
of the large scale multi-institutional and international<BR>oceanographic
biogeochemical and tracer programs of the last two decades,<BR>including the
Geochemical Ocean Sections Study program, the Transient<BR>Tracers in the Oceans
program, and the South Atlantic Ventilation<BR>Experiment. He is active in the
ongoing World Ocean Circulation<BR>Experiment, Joint Global Ocean Flux Study,
and International<BR>Geosphere-Biosphere Program. He served on the Climate
Research Committee<BR>and Committee on Oceanic Carbon of the National Research
Council, as well<BR>as on the Advisory Committee of Ocean Sciences of the
National Science<BR>Foundation. He was on the editorial board of the Journal of
Marine<BR>Research, Climate Dynamics, and Global Biogeochemical
Cycles.<BR><BR></STRONG></FONT><FONT face=Arial size=2>--
