NEW COMPETITIVE COOPERATIVE AGREEMENT WITH GE VERNOVA OPERATIONS LLC, DE-FOA-0002989 (SEA CO2) CONTROL# 2989-1534 PROJECT TITLE: ''SPATIALLY RESOLVED MULTI-PARAMETER SENSING OF OCEAN CARBON DYNAMICS UTILIZING FIBER OPTIC TIME-OF-FLIGHT SENSORS.'' THE PRIMARY OBJECTIVES OF THE PROJECT ARE: I) TO DEVELOP A NOVEL FIBER OPTIC SENSOR FOR HIGH FIDELITY MEASUREMENT OF MARINE PH AND PCO2, II) TO DESIGN A DISTRIBUTED MEASUREMENT SYSTEM THAT SPANS KILOMETERS HORIZONTALLY WITH SPATIAL RESOLUTION OF 5 – 20 M AND CAN BE DEPLOYED VERTICALLY DOWN TO ~1 KM DEPTH, III) TO ENABLE ROBUST MEASUREMENTS DISENTANGLED FROM ENVIRONMENTAL DISTURBANCE AND BIOLOGICAL ACTIVITY (I.E., PHOTOSYNTHESIS AND RESPIRATION), IV) TO DEMONSTRATE DURABILITY AGAINST BIOFOULING AND OTHER FACTORS IMPACTING LONG-TERM STRUCTURAL AND MEASUREMENT INTEGRITY OF THE SYSTEM, V) TO VALIDATE MEASUREMENT PERFORMANCE ON AN EXISTENT MCDR FIELD AND VI) TO ILLUSTRATE SCALABILITY OF THE MEASUREMENT SYSTEM ON LARGE OCEAN EXPANSES, BASED ON MOBILE SWEEPING OF THE OCEAN, WITH A TECHNO-ECONOMIC ANALYSIS.
