Downward particle flux measurments collected during the SOLACE cruise (Pacific sector of the Southern Ocean)

Matière particulaire

This dataset was collected from the Marine National Facility RV Investigator voyage IN2020_V08, titled: "SOLACE - Southern Ocean Large Areal Carbon Export: quantifying carbon sequestration in subpolar and polar waters". The voyage took place between 4th December 2020 and 15th January 2021, departing from Hobart (TAS) and arriving in Hobart (TAS). The aim of this voyage was to quantify both the physical and biological downward carbon export pathways. This dataset describes the gravitational pump and includes raw and processed data. A free-drifting surface-tethered array, mounted with 3 particle interceptor traps (PIT), and 3 C-RESPIREs (i.e., dual particle interceptors/incubators), was deployed for a period of 3 days, on 7 consecutive deployments at 3 contrasting sites. The PITs and C-RESPIREs were deployed at 3 depths between ~180-300 m. POC, PON, BSi, pigments and numerical particle fluxes were measured with the traps. Carbon-specific microbial remineralization rates, size-specific sinking velocities and UVP-derived POC flux were estimated for each deployment site.
