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

75           News is back by popular request. New advection schemes are currently
76           being tested. Some preliminary results from the new schemes can be seen
77           <A href=news/advection_testing_jan07/advection_testing.html>
78           here.

80           The plots show a tracer being transported and stretched in the
81           MITgcm advect_xz verification test. Both new schemes (OS7MP
82           and Prather second-order scheme with limiting) have very low implied
83           diffusivity.
84           We are currently evaluating the
85           schemes to assess their implied diffusivity, with a bottle of
86           Jean-Michel's favorite Belgian
87           beer going to the the least diffusive scheme - watch this space!

92           A short article entitled
93           "NASA Supercomputer Improves Prospects for Ocean Climate Research"
94           in the current EOS (volume 86, number 9, March 1 2005)
95           gives a succinct overview of some of the advanced high-resolution
96           state-estimation work being undertaken with MITgcm by members
97           of the ECCO consortium. The article describes
98           ground-breaking computational
99           technologies that have enabled this work and outlines the future goals of
100           this next generation planetary scale assimilation initiative. A pdf containing
101           the article can be found
