|Title:||Linking the Biological Carbon Pump flux to microbial colonisation of sinking particles in the Coral Sea|
|Investigator(s):|| Viena Puigcorbe
Edith Cowan University [details]
|Description:||Scientific and voyage objectives: to conduct a research program in the oligotrophic waters of the Coral Sea to: 1: Evaluate carbon export fluxes and the carbon export efficiency 2: Assess the changes of the microbial community structure in particles from surface to mesopelagic ocean 3. Link the rates of carbon export and remineralisation (Aim 1) to the microbial community changes (Aim 2) through experiments under controlled conditions. The oceanographic characteristics of the previously sampled areas are dramatically different to the Coral Sea, however, the oligotrophic areas of the ocean, as the Coral Sea, are expected to expand with the prediction of a future warmer ocean. Additionally, these oceanic regions have been disregarded when referring to carbon export, but recent research has shown that subtropical regions with picoplankton-dominated food webs are characterised by enhanced export efficiencies. The results from this project will deepen our understanding of carbon export and the impact of the microbial community in the carbon export efficiency in oligotrophic waters, which will help constrain the marine carbon cycle and should benefit future climate models.|

|V. Puigcorbe (Edith Cowan University)|| RV Investigator transit voyage between Brisbane and Darwin: in2021_T01, with the following supplementary and piggyback projects:
The primary objective of voyage IN2021_T01 is movement of RV Investigator from Brisbane to Darwin in preparation for IN2021_V04. Up to 72 hours of the transit voyage have been allocated to conduct scientific operations which will consist of a minimum of 12hrs devoted to the Supplementary Project: Microplastics in the food chain: impact on the microbial and planktonic organisms. The remaining time can be available for multiple Piggyback Projects. Some opportunistic mapping has been prepared should we be ahead of schedule.
