Absence of photophysiological response to iron addition in autumn phytoplankton in the Antarctic sea-ice zone
Singh, Asmita; Fietz, Susanne; Thomalla, Sandy J.; Sanchez, Nicolas; Ardelan, Murat V.; Moreau, Sebastian; Kauko, Hanna Maria; Fransson, Agneta; Chierici, Melissa; Samanta, Saumik; Mtshali, Thato N.; Roychoudhury, Alakendra N.; Ryan-Keogh, Thomas J. (Peer reviewed; Journal article, 2023)he high nutrient–low chlorophyll condition of the Southern Ocean is generally thought to be caused by the low bioavailability of micronutrients, particularly iron, which plays an integral role in phytoplankton photosynthesis. ... -
Phenology and Environmental Control of Phytoplankton Blooms in the Kong Håkon VII Hav in the Southern Ocean
Kauko, Hanna Maria; Hattermann, Tore; Ryan-Keogh, Thomas J.; Singh, Asmita; de Steur, Laura; Fransson, Agneta; Chierici, Melissa; Falkenhaug, Tone; Hallfredsson, Elvar H.; Bratbak, Gunnar; Tsagaraki, Tatiana Margo; Berge, Terje; Zhou, Qin; Moreau, Sebastien (Peer reviewed; Journal article, 2021)Knowing the magnitude and timing of pelagic primary production is important for ecosystem and carbon sequestration studies, in addition to providing basic understanding of phytoplankton functioning. In this study we use ... -
Wind-driven upwelling of iron sustains dense blooms and food webs in the eastern Weddell Gyre
Moreau, Sebastian; Hattermann, Tore; de Steur, Laura; Kauko, Hanna Maria; Ahonen, Heidi; Ardelan, Murat van; Assmy, Philipp; Chierici, Melissa; Descamps, Sebastien; Dinter, Tilman; Falkenhaug, Tone; Fransson, Agneta; Grønningsæter, Eirik; Hallfredsson, Elvar Halldor; Huhn, Oliver; Lebrun, Anais; Lowther, Andrew; Lübcker, Nico; Monteiro, Pedro; Peeken, Ilka; Roychoudhury, Alakendra; Różańska, Magdalena; Ryan-Keogh, Thomas; Sanchez Puerto, Nicolas; Singh, Asmita; Simonsen, Jan Henrik; Steiger, Nadine; Thomalla, Sandy J.; van Tonder, Andre; Wiktor, Josef M; Steen, Harald (Peer reviewed; Journal article, 2023)The Southern Ocean is a major sink of anthropogenic CO2 and an important foraging area for top trophic level consumers. However, iron limitation sets an upper limit to primary productivity. Here we report on a considerably ...
