The phytoplankton abundances increased with ... -
Environmental effects on Calanus finmarchicus abundance and depth distribution in the Barents Sea
Kvile, Kristina Øie; Prokopchuk, Irina P.; Stige, Leif Christian (Peer reviewed; Journal article, 2021)The vertical migrations performed by zooplankton at daily and seasonal scales are important for marine ecosystem dynamics and biogeochemical cycles. We analysed associations between seasonal variation in abundance and depth ... -
Long-term coastal monitoring data show nutrient-driven reduction in chlorophyll
Lundsør, Elisabeth; Stige, Leif Christian; Sørensen, Kai; Edvardsen, Bente (Peer reviewed; Journal article, 2020)In this study we have compiled a long-term monitoring dataset from the inner Oslofjorden and supplemented it with short-term research data from the same station. Using generalized additive models analysing the data from ...
