OCCA

Surface height anomaly from OCCAThis month we focus on work by Gael Forget and the ECCO team who have been using MITgcm to construct a new ocean atlas. By using MITgcm as a means of optimally synthesising data within the framework of a physically accurate general circulation model, OCCA (short for OCean Comprehensible Atlas) provides a singularly accurate 3-year “snap-shot” of the global ocean state for the period December 2003 to November 2006…


Lake Modeling

Figure 1. Summer-time, mean circulation. The plot shows depth integrated current (arrows) overlying column average water temperature (colored). Arrows illustrating vector flow are plotted every 5 grid-points.

Work by Galen McKinley and Val Bennington at the University of Wisconsin, Madison using MITgcm to model the general circulation of Lake Superior as part of a project to develop a quantitative understanding of the role such bodies of water may play in the terrestrial carbon cycle…
