KM2209 SCOPE-PARAGON-2 cruise, Wirewalker

This dataset was collected during the 2022 SCOPE-PARAGON-2 cruise. This cruise was directed towards understanding the processes and rates of biological particulate matter transformations (e.g., production, decomposition, sinking) as well as the ecological interactions that occur in association with suspended and sinking particles. These targeted studies of particle dynamics at Station ALOHA leveraged ongoing ecological and biogeochemical modeling efforts in SCOPE. The Wirewalker is a  wave-powered drifting profiler designed to collect autonomous, vertically-resolved oceanographic observations. The profiler moves along a wire that is suspended between a float at the sea surface and a weight placed at a depth of tens or hundreds of meters. The system horizontal displacement follows the ocean currents. Wirewalker measurements include temperature, salinity, depth, beam attenuation, backscattering, chlorophyll fluorescence, CDOM fluorescence, downwelling irradiance in four spectral bands, and dissolved oxygen concentration.
