Ocean Ecosystems

Figure 1. Illustration of the key components in the self-assembling phytoplankton community model. After some years of interaction, the fittest "types" persist and occupy distinct habitats.Work by Fanny Monteiro with Mick Follows and Stephanie Dutkiewicz at MIT who have been using the MITgcm to probe the behaviour of self-assembling phytoplankton communities within a global ocean circulation…

Sea Ice

Figure 1. Arctic and Antarctic results from an eddy-permitting, MITgcm, global ocean and sea-ice simulation: Sea ice thickness distribution (color, in meters) averaged over the years 1992-2002. The ice-edge (estimated as the 15% isoline of ice concentration) retrieved from passive microwave satellite data is shown as a white contour for comparison. The top row shows the results for the Arctic Ocean and the bottom row for the Antarctic Oceans; the left column shows distributions for March and the right column for September.Work by Martin Losch of the Alfred-Wegener-Institute, Bremerhaven, Germany, Jean Michel Campin, Patrick Heimbach, Chris Hill (at MIT) and Dimitris Menemenlis (JPL) extending the reach of the MITgcm in to the Polar oceans, with the development of a dynamic-thermodynamic sea-ice model and its adjoint…

PRM

Figure 1. Temperature sections after 60 hours from (top left) the fully resolved model, (bottom left) the multi-scale simulation and (bottom right) the balanced model with a simple convective adjustment algorithm.Work by Jean-Michel Campin, Chris Hill, Helen Jones and John Marshall at MIT using the MITgcm to exploit a multi scale superparameterization approach to increase efficiency in modeling oceanic deep convection (ODC)…

Aqua Planets

Figure 1. With the northern pole in view to the left, the southern pole to the right, sea surface temperature, and sea-ice height from the Double Drake experiment.Using a coupled ocean-atmosphere version of the MITgcm to study an Earth-like planet which is entirely covered by ocean, David Ferreira and John Marshall, are exploring the elemental role of the ocean in climate…

Adjoint Advances

Adjoint Advances story by Helen Hill Two MITgcm adjoint activities are (i) the development of an open-source, extensible automatic differentiation tool, OpenAD and (ii) the configuration of an ~18km resolution global ocean and sea-ice experiment as part of the ECCO2 project.
