dc.description.abstractThe ocean plays a crucial role in regulating atmospheric carbon dioxide yet quantifying the processes that govern its carbon storage remains a challenge. The biological pump converts CO₂ into organic particles, some of which remain suspended while others sink, either individually or as larger aggregates. This sinking contributes to long-term carbon sequestration in the subsurface ocean. Measuring these particles is difficult, but optical backscatter offers a solution. We adapted a method for Argo floats to process optical data from ocean gliders, partitioning backscatter into three components: large aggregates, smaller particles, and instrument noise. Using a two-filter method, we isolated smaller particle scattering and estimated noise from deeper backscatter measurements. Data collected in offshore British Columbia waters by a Canadian-Pacific Robotic Ocean Observing Facility (C-PROOF) glider deployment, revealed regions of high productivity dominated by smaller particles, while others had large aggregates. Our method improves glider-based carbon cycle research and has broader applications across additional glider missions.
