Data-based models of plankton community structure and export flux

PROJECT DESCRIPTION: |
Intensive JGOFS investigations over the past decade have indicated strong
links among physical-chemical environmental forcing, plankton community
structure, and the fate of carbon production (remineralization or export).
However, these relationships are crudely portrayed in existing plankton
food web models. It is presently unclear how much information on size and
taxonomic composition is needed for adequate model predictions and to what
extent community dynamics and biogeochemical fluxes in different water
masses are linked by common organizational principles and quantitative
relationships.
The overall goal of the proposed research is to contribute to the mechanistic understanding of the factors that regulate "euphotic zone production and export of carbon and related biologically active substances" (SMP Element #2) by developing and evaluating data-based models of plankton community structure and export flux for tropical/subtropical open-ocean ecosystems. This project will focus on the tropical and subtropical oceans, areas most strongly represented in JGOFS Process and Time-series studies (EqPac, Arabian Sea, HOT, BATS) and presently most developed in terms of mature databases and supporting experimental studies. Our specific objectives, which also outline a systematic approach to the proposed research, are:
