Ecological Provinces from a computer simulation of the marine global ecosystems. Each color represents a different distinct combination of the most dominant phytoplankton function types (as shown in the Venn diagram top right). The opacity indicates the total concentration of phytoplankton biomass: the darker the color, the less phytoplankton – Animation Credit: Oliver Jahn, MIT Download (43MB)
Output from ECCO2/GUD simulation. This simulation includes 35 phytoplankton types grouped into 6 different Phytoplankton types and spanning from a cell diameter of 0.6μm to 200 μm. The movie shows four different phytoplankton functional types superimposed over Chl concentrations (white intensity). Red=diatoms; pink=Coccolithophores; green=picophytoplankton; blue=diazotrophs – Animations courtesy the Darwin Project.
Output from ECCO2/GUD simulation. This simulation include 35 phytoplankton types grouped into 6 different Phytoplankton types and spanning from a cell diameter of 0.6μm to 200 μm. The movie shows the log of the mean size of the phytoplankton (equivalent spherical diameter). The scaling is logarithmic, so “0″ indicates that the mean size of all the phytoplankton at that location is 1μm, and “1″ is 10μm – Animation courtesy: The Darwin Project
Output from ECCO2/GUD simulation. This simulation include 35 phytoplankton types grouped into 6 different Phytoplankton types and spanning from a cell diameter of 0.6 μm to 200 μm. The movie shows Chl (mg/m³) in the top panel and a representation of the community structure in the lower panel. The more red, the larger the percentage of phytoplankton larger than 2μm; the greener the larger percentage smaller than 2μm. Overlain in blue is the biogeography of the diazotrophs – Animation courtesy: The Darwin Project.
Modeled surface ocean Chi-a concentration. Modeled surface ocean Chl-a concentration (the sum of contributions from 78 initialized phytoplankton types) from the eddy-permitting simulation.
Diverse phytoplankton in Gulf Stream Movie contrasting two phytoplankton species present in the gulf stream: One that is adapted to the local conditions and thrives locally (upper half) and one that is not adapted but gets transported in to the region from a different region. Shown is concentration in mmol P/m2, 1 year simulation.
Modeled phytoplankton types on cubed sphere Dominant phytoplankton types during 1994-1998 from a high-resolution ocean and ecosystem model. Colors represent the most dominant type of phytoplankton at a given location.Four functional groups of phytoplankton in a global ocean model – red: corresponds to diatoms (big, need silica), yellow: other big phytoplankton, green: Prochlorococcus-like (small, cannot use NO3) and cyan: other small phytoplankton. The model contains flow fields from 1994-1998 (ECCO2), inorganic nutrients, 78 species of phytoplankton, zooplankton and particulate and dissolved organic matter.
