BN21B:
We Shed Light: Optical and Imaging Insights into the Biological Carbon Pump I


Session ID#: 37155

Session Description:
The urgent need to improve our understanding of ocean carbon sequestration and the Biological Carbon Pump (BCP) has led to the rapid advance of marine autonomous sensors and new technologies focussing on in situ optical measurements (e.g. backscatter/fluorescence sensors and camera systems). These produce large data sets describing the size, type and distribution of sinking biological particles driving the BCP. Marine autonomous instruments offer greater spatio-temporal coverage than traditional sediment traps and reduce ship time, critically improving our understanding of the BCP and promising unprecedented insight into interactions among organisms and particles. Yet, whilst these technologies have advanced greatly during the last two decades, the application of these datasets in the study of the BCP remains limited and prone to uncertainties such as the linkages between optical particle properties and particle characteristics such as composition, inner structure, sinking speed, sources, and flux. We invite submissions that showcase: (1) Case studies highlighting the use of optical devices to characterize the Biological Carbon Pump,(2) Advances in particle image classification (including zooplankton),(3) Advances in understanding relationships between optical particle properties and sinking speed/carbon content, flux calculations, and (4) Novel insights from optical devices into particle dynamics, including zooplankton-particle dynamics and numerical models.
