THIS PROPOSAL RESPONDS TO THE AMENDMENT A.3. OBB CALL FOR THE EXPORTS FIELD CAMPAIGN. USING SATELLITE REMOTE SENSING DATA TO PREDICT EXPORT AND FATE OF NET PRIMARY PRODUCTION (NPP) IN A GIVEN REGION AND TIME REQUIRES AN UNDERSTANDING OF THE DRIVERS AND CHARACTERISTICS OF PLANKTON COMMUNITY STRUCTURE. THE EXPORTS SCIENCE PLAN CHARACTERIZES 5 PATHWAYS FOR THE EXPORT OF NPP FROM THE SURFACE OCEAN INTO THE INTERIOR TWO OF WHICH ARE MEDIATED BY MESOZOOPLANKTON: PRODUCTION AND SINKING OF FECAL PELLETS AND ACTIVE TRANSPORT BY VERTICAL MIGRATION. WE PROPOSE TO ADDRESS EXPORTS SCIENCE QUESTIONS SQT (TA AND TB) AND SQ2 (2A B D) BY CONDUCTING FIELD-BASED PROCESS STUDIES OF MESOZOOPLANKTON-MEDIATED EXPORT IN THE NE PACIFIC AND N ATLANTIC OCEANS. THE GUIDING HYPOTHESIS IS THAT CHANGES IN PHYTOPLANKTON COMMUNITY STRUCTURE AND NPP AFFECT ZOOPLANKTON ABUNDANCE BIOMASS SIZE AND TAXONOMIC STRUCTURE ALL OF WHICH CONTROLS AND SCALES TO EXPORT IN A QUANTIFIABLE AND PREDICTABLE WAY. SATELLITE OBSERVABLES AND DATA PRODUCTS INCLUDING EUPHOTIC ZONE PHYTOPLANKTON BIOMASS AND FUNCTIONAL TYPE PARTICLE SIZE SPECTRUM LIGHT ATTENUATION AND TEMPERATURE WILL BE USED TO PREDICT ZOOPLANKTON COMMUNITY STRUCTURE AND IN TURN ZOOPLANKTON-MEDIATED EXPORT SIGNIFICANTLY ADVANCING OUR ABILITY TO PREDICT EXPORT AND FATE OF NPP.
