Heterotrophic nanoflagellate grazing facilitates subarctic Atlantic spring bloom development
Paulsen, Maria Lund; Riisgård, Karen; St. John, Mike; Thingstad, T. Frede; Nielsen, Torkel Gissel (Peer reviewed; Journal article, 2017)The subarctic Atlantic phytoplankton spring bloom is one of the largest biological features of the ocean; however, processes initiating the bloom are still not well understood. We hypothesize that the microbial grazing ... -
Phytoplankton dynamics in contrasting early stage North Atlantic spring blooms: composition, succession, and potential drivers
Daniels, Chris; Poulton, Alex J.; Mario, Esposito; Paulsen, Maria Lund; Bellerby, Richard; St. John, Mike; Martin, Adrian P. (Peer reviewed; Journal article, 2015-04-24)The spring bloom is a key annual event in the phenology of pelagic ecosystems, making a major contribution to the oceanic biological carbon pump through the production and export of organic carbon. However, there is little ... -
Winter−spring transition in the subarcticAtlantic: microbial response to deep mixingand pre-bloom production
Paulsen, Maria Lund; Riisgaard, Karen; Frede, Thingstad; St. John, Mike; Nielsen, Torkel Gissel (Peer reviewed; Journal article, 2015-09-23)In temperate, subpolar and polar marine systems, the classical perception is that diatoms initiate the spring bloom and thereby mark the beginning of the productive season. Contrary to this view, we document an active ...
