38          Breaking News:  The MITgcm is now able to generate Sea-Ice Donuts.
39          In a push to move forward MITgcm on the path of fundamental science and climate
40          understanding, David Ferreira and Jean-Michel Campin
41          simulated a Sea-ice Donut using a coupled AquaPlanet configuration (see
42          movie <A href="/movies/Sea_Ice_Donut_x1.mpg">here</A>).
43          This experiment was initialized with  the T and S fields from
44          a previous Aquaplanet run which has polar sea-ice caps. These
45          caps are associated with salt-compensated temperature inversions in the upper
46          ocean. The new run is initialized without sea-ice and within a month, large
47          sea-ice caps grow over the poles, rejecting salt. This triggers convection which
48          in turns brings relatively warm water to the surface and melts the ice close
49          to the poles. Here we have a <A href="/movies/Sea_Ice_Donut_x1.mpg">donut</A>.
50          Look out for that chapter on aqua-planets in the next IPCC report!

55           News is back by popular request. New advection schemes are currently
56           being tested. Some preliminary results from the new schemes can be seen
57           <A href="/projects/advection_test_jan07/advection_testing.html">
58           here.

60           The plots show a tracer being transported and stretched in the
61           MITgcm advect_xz verification test. Both new schemes (OS7MP
62           and Prather second-order scheme with limiting) have very low implied
63           diffusivity.
64           We are currently evaluating the
65           schemes to assess their implied diffusivity, with a bottle of
66           Jean-Michel's favorite Belgian
67           beer going to the the least diffusive scheme - watch this space!

72           A short article entitled
73           "NASA Supercomputer Improves Prospects for Ocean Climate Research"
74           in the current EOS (volume 86, number 9, March 1 2005)
75           gives a succinct overview of some of the advanced high-resolution
76           state-estimation work being undertaken with MITgcm by members
77           of the ECCO consortium. The article describes
78           ground-breaking computational
79           technologies that have enabled this work and outlines the future goals of
80           this next generation planetary scale assimilation initiative. A pdf containing
81           the article can be found

89            MITgcm is now able to write and (to a lesser extent) read NetCDF files.
90            The framework (the "MNC" package) has been tested by numerous developers
91            on literally dozens of machines and, for the past month, has been a
92            working part of our standard verification suite.  We encourage MITgcm
93            users (especially new users) to try out the MNC package since the model
94            output is now much easier to read and understand.  For further NetCDF
95            information please see:

120            over the North Pole. The viscous-plastic behavior of ice sheets subject
121            to wind forcing and ocean currents can be clearly seen in the
122            translucent ice-sheet. The movie can be downloaded from <a

138            A spectacular movie by Chris Henze of NASA AMES beautifully captures an

140            as part of the <a href="http://www.ecco-group.org">ECCO</a> project, by
141            Dimitris Menemenlis and others at JPL with help from core MITgcm team members
142            and staff from NASA AMES. The animation
143            shows the speed of ocean currents at 15m depth from the simulation, it can be
144            downloaded <a href="/movies/cube_6.mpg">here</a> (its 47MB
145            but worth waiting for!). A second animation with different perspectives and
146            rotation can be downloaded <a href="/movies/cube_7.mpg">here</a>.
147            As described <a href="/pdfs/agu_2004/menemenlis_et_al.pdf">here</a> Dimitris
148            Menemenlis will be presenting aspects of this calculation at AGU in Portland.
