As sea ice is declining rapidly in the Arctic, phytoplankton are being exposed to very different light regimes. Here we investigated how phytoplankton photoacclimate in three different irradiance regimes: under the ice, in the marginal ice zone, and

Light and iron availability are intertwined in controlling Southern Ocean primary production because several photosynthetic proteins require iron. Changes in light and iron availability can also affect phytoplankton species composition, which impacts

Light Is the Primary Driver of Early Season Phytoplankton Production Along the Western Antarctic Peninsula

Autor: Hannah L. Joy-Warren, Kate M. Lewis, Gert L. van Dijken, Kevin R. Arrigo, Kate E. Lowry, Virginia Selz, Willem H. van de Poll, Anne-Carlijn Alderkamp, Amy Leventer

Publikováno v: Journal of geophysical research: Oceans, 124(11), 7375-7399

Light and dissolved iron (dFe) availability control net primary production (NPP) in much of the Southern Ocean, but the primary controller during spring in the western Antarctic Peninsula has never been assessed. Underwater light and dFe availability

Waters of the Southern Ocean are characterized by high macronutrient concentrations but limited availability of trace metals and light, often making it difficult for phytoplankton to achieve maximum growth rates. One strategy employed by Southern Oce

Publikováno v: Marine Ecology Progress Series, 586, 91-112. INTER-RESEARCH

The western Antarctic Peninsula has experienced extreme changes in the timing of sea ice melt and freeze up, shortening the duration of the seasonal sea ice cycle. While previous research demonstrated connections between multiple pelagic trophic leve

The Palmer Long-Term Ecological Research program has sampled waters of the western Antarctic Peninsula (wAP) annually each summer since 1990. However, information about the wAP prior to the peak of the phytoplankton bloom in January is sparse. Here w

MESMO 2: a mechanistic marine silica cycle and coupling to a simple terrestrial scheme

Autor: Kathy S. Tokos, Hannah L. Joy-Warren, Katsumi Matsumoto, A. Huston

Publikováno v: Geoscientific Model Development, Vol 6, Iss 2, Pp 477-494 (2013)

Here we describe the second version of Minnesota Earth System Model for Ocean biogeochemistry (MESMO 2), an earth system model of intermediate complexity, which consists of a dynamical ocean, dynamic-thermodynamic sea ice, and energy moisture balance
