Extracellular enzyme activity in the coastal upwelling system off Peru: A mesocosm experiment
Spilling, Kristian; Piiparinen, Jonna; Achterberg, Eric P.; Arístegui, Javier; Bach, Lennart T.; Camarena-Gómez, Maria T.; Von Der Esch, Elisabeth; Fischer, Martin A.; Gómez-Letona, Markel; Hernández-Hernández, Nauzet; Meyer, Judith; Schmitz, Ruth A.; Riebesell, Ulf (Peer reviewed; Journal article, 2023)The Peruvian upwelling system is a highly productive ecosystem with a large oxygen minimum zone (OMZ) close to the surface. In this work, we carried out a mesocosm experiment off Callao, Peru, with the addition of water ... -
Microzooplankton communities and their grazing of phytoplankton under artificial upwelling in the oligotrophic ocean
Spilling, Kristian; Arellano San Martín, Mirian; Granlund, Mira; Schulz, Kai G.; Spisla, Carsten; Vanharanta, Mari; Goldenberg, Silvan Urs; Riebesell, Ulf (Peer reviewed; Journal article, 2023)Ocean artificial upwelling has been suggested to boost primary production and increase harvestable resources such as fish. Yet, for this ecosystem-based approach to work, an effective energy transfer up the food web is ... -
Respiration rate scales inversely with sinking speed of settling marine aggregates
Spilling, Kristian; Heinemann, Malte; Vanharanta, Mari; Baumann, Moritz; Noche Ferreira, Andrea; Suessle, Philipp; Riebesell, Ulf (Peer reviewed; Journal article, 2023)Sinking marine aggregates have been studied for a long time to understand their role in carbon sequestration. Traditionally, sinking speed and respiration rates have been treated as independent variables, but two recent ... -
