Imperial College London (United Kingdom) is hiring for a fixed-term, 2-year research associate position based at their Silwood Park Campus to contribute to contribute to Work Package 3 of the OceanSOS project. The role will focus on identifying how seafloor topology influences the mesopelagic biological carbon pump, specifically looking at particle type, size and microbial remineralisation across a seamount and abyssal plain. The position is part of a wider team capturing the contributions of larger organisms, deep-sea communities and connections between the seafloor and the open ocean in the BCP. This role will involve seagoing expeditions in the North Atlantic (Summer 2027) and will use multiple techniques to determine the regional BCP, to then feed into the physical, food-web and statistical models used by the OceanSOS team. The post-holder will also facilitate fieldwork south of South Africa (early Summer 2027) and the samples collected from this region. Applications close on 30 November 2026.
