AS ATMOSPHERIC CARBON DIOXIDE CONCENTRATIONS CONTINUE TO RISE IT IS IMPERATIVE TO UNDERSTAND HOW THIS ENVIRONMENTAL CHANGE IMPACTS THE OCEAN. THE OCEAN HOLDS SUBSTANTIALLY MORE CARBON DIOXIDE THAN THE ATMOSPHERE MAKING IT A CRITICAL COMPONENT OF THE GLOBAL CARBON CYCLE. THE BIOLOGICAL PUMP PART OF THE OCEAN CARBON CYCLE OFFERS A MAJOR PATHWAY FOR CARBON DIOXIDE IN THE ATMOSPHERE TO REACH ITS FATE OF LONG TERM STORAGE IN THE OCEAN. THIS OCCURS THROUGH A SERIES OF PROCESSES WHERE PHYTOPLANKTON CONSUME CARBON DIOXIDE DISSOLVED IN THE OCEAN. THEN AS PHYTOPLANKTON DIE OR ARE CONSUMED AND EXCRETED BY HIGHER TROPHIC ORGANISMS CLUSTERED FORMS OF PARTICULATE ORGANIC CARBON ARE CREATED. THE MORE DENSE PARTICULATE ORGANIC CARBON SINKS AND WHAT IS NOT RECYCLED OR REINTRODUCED INTO THE SURFACE OCEAN BEFORE SINKING TO DEPTH BECOMES CARBON STORED FOR DECADES TO MILLENNIA. DESPITE THE IMPORTANCE OF THE BIOLOGICAL CARBON PUMP IN LONG TERM CARBON STORAGE ESTIMATES OF THE BIOLOGICAL CARBON PUMP CONTAIN LARGE UNCERTAINTIES AND PREDICTIONS OF HOW IT WILL CHANGE WITH RISING CARBON DIOXIDE CONCENTRATIONS AND GLOBAL WARMING ARE NOT WELL UNDERSTOOD. THIS STUDY WILL ADDRESS NASA S PROGRAMATIC GOALS TO PREDICT HOW GLOBAL BIOGEOCHEMICAL CYCLES ARE CHANGING. IMPROVING HOW WE UNDERSTAND THE BIOLOGICAL PUMP IS A CRITICAL FIRST STEP TO BEING ABLE TO DETECT AND PREDICT HOW IT WILL CHANGE GOING FORWARD. THIS STUDY COMBINES IN SITU AND SATELLITE-DERIVED ESTIMATES OF NET COMMUNITY PRODUCTION (NCP) AN IMPORTANT METRIC OF THE BIOLOGICAL PUMP THAT REPRESENTS AMOUNT OF PARTICULATE ORGANIC CARBON AVAILABLE FOR EXPORT AND EVENTUALLY LONG TERM STORAGE. THE THREE KEY GOALS THAT WILL BE ADDRESSED USING DATA COLLECTED DURING THE NASA EXPORTS FIELD CAMPAIGNS IN THE NORTH PACIFIC AND NORTH ATLANTIC OCEANS ARE AS FOLLOWS: 1) USE A FAST PROFILING WAVE POWERED WIREWALKER TO IMPROVE ESTIMATES OF NCP THROUGH OBSERVATIONS OF DIURNAL CHANGES IN DISSOLVED OXYGEN CONCENTRATIONS. 2) USE THE HIGH-RESOLUTION WIREWALKER NCP ESTIMATES TO BETTER UNDERSTAND THE LIMITATIONS AND UNCERTAINTY INTRODUCED IN MORE COMMON LOWER FREQUENCY AUTONOMOUS PLATFORMS SUCH AS FLOATS AND GLIDERS. 3). USE A WATER-FOLLOWING SIMULATION TO COMPUTE NCP FROM CHANGES IN OCEAN COLOR AND COMPARE IN SITU NCP ESTIMATES TO SATELLITE-DERIVED NCP TO EVALUATE UNCERTAINTY IN OCEAN COLOR ESTIMATES OF NCP.
