    • A non-diatom plankton bloom controlled by copepod grazing and amphipod predation: Preliminary results from the LOHAFEX iron-fertilisation experiment 

      Mazzocchi, M.G.; Gonzalez, H.E.; Vandromme, P.; Borrione, I.; deAlcala, M.R.; Gauns, M.; Assmy, P.; Fuchs, B.; Klaas, C.; Martin, P.; Montresor, M.; Ramaiah, N.; Naqvi, S.W.A.; Smetacek, V. (GLOBEC, 2009)
      The most memorable LOHAFEX cruise came to an end on 17 March 2009 when RV Polarstern docked in the harbour of Punta Arenas (southern Chile) after successfully carrying out the longest iron fertilisation experiment so far ...
    • Deep carbon export from a Southern Ocean iron-fertilized diatom bloom 

      Smetacek, V.; Klaas, C.; Strass, V.H.; Assmy, P.; Montresor, M.; Cisewski, B.; Savoye, N.; Webb, A.; d’Ovidio, F.; Arrieta, J.M.; Bathmann, U.; Bellerby, R.; Berg, G.M.; Croot, P.; Gonzalez, S.; Henjes, J.; Herndl, G.J.; Hoffmann, L.J.; Leach, H.; Losch, M.; Mills, M.M.; Neill, C.; Peeken, I.; Rottgers, R.; Sachs, O.; Sauter, E.; Schmidt, M.M.; Schwarz, J.; Terbruggen, A.; Wolf-Gladrow, D. (Nature Publishing Group, 2012)
      Fertilization of the ocean by adding iron compounds has induced diatom-dominated phytoplankton blooms accompanied by considerable carbon dioxide drawdown in the ocean surface layer. However, because the fate of bloom biomass ...
    • Iron partitioning during LOHAFEX: Copepod grazing as a major driver for iron recycling in the Southern Ocean 

      Laglera, L.M.; Tovar-S�nchez, A.; Iversen, M.H.; Gonz�lez, H.E.; Naik, H.; Gauns, M.; Assmy, P.; Klaas, C.; Mazzocchi, M.G.; Montresor, M.; Naqvi, S.W.A.; Smetacek, V.; Wolf-Gladrow, D.A. (Elsevier, 2017)
      The LOHAFEX iron fertilization experiment was conducted for 39days in the closed core of a cyclonic mesoscale eddy located along the Antarctic Polar Front in the Atlantic sector of the Southern Ocean. Mixed layer (ML) ...
    • Remarkable structural resistance of a nanoflagellate-dominated plankton community to iron fertilization during the Southern Ocean experiment LOHAFEX 

      Schulz, I.; Montresor, M.; Klaas, C.; Assmy, P.; Wolzenburg, S.; Gauns, M.; Sarkar, Amit; Thiele, S.; Wolf-Gladrow, D.; Naqvi, S.W.A.; Smetacek, V. (Inter-Research Science Center, Oldendorf/Luhe, Germany, 2018)
      The genesis of phytoplankton blooms and the fate of their biomass in iron-limited, high-nutrient-low-chlorophyll regions can be studied under natural conditions with ocean iron fertilization (OIF) experiments. The Indo-German ...
    • Thick-shelled, grazer-protected diatoms decouple ocean carbon and silicon cycles in the iron-limited Antarctic Circumpolar Current 

      Assmy, P.; Smetacek, V.; Montresor, M.; Klaas, C.; Henjes, J.; Strass, V.H.; Arrieta, J.M.; Bathmann, U.; Berg, G.M.; Breitbarth, E.; Cisewski, B.; Friedrichs, L.; Fuchs, N.; Herndl, G.J.; Jansen, S.; Kragefsky, S.; Latasa, M.; Peeken, I.; Rottgers, R.; Scharek, R.; Schuller, S.E.; Steigenberger, S.; Webb, A.; Wolf-Gladrow, D. (National Academy of Sciences of the United States of America, 2013)
      Diatoms of the iron-replete continental margins and North Atlantic are key exporters of organic carbon. In contrast, diatoms of the iron-limited Antarctic Circumpolar Current sequester silicon, but comparatively little ...
