Svenja Halfter is a zooplankton ecologist and biogeochemist based at NIWA in Wellington, New Zealand. Their research focuses on understanding the zooplankton dynamics and the impact of climate change on lower trophic levels in the Southern Ocean, mainly in the Indian and Pacific sectors. During their PhD, Svenja worked on zooplankton-mediated carbon flux in the subantarctic Southern Ocean and was part of MEASO (Marine Ecosystem Assessment of the Southern Ocean). Svenja is involved in the SOOS RWG for the Indian Sector since 2020, first as an APECS ECR representative and now as a full member. Outside of SOOS, Svenja is also part of the SCAR Expert Group on Antarctic Biodiversity Informatics, the SCAR scientific research program Ant-ICON, and the Ocean Decade program JETZON (Joint Exploration of the Twilight Zone Ocean Network).
