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.
59     </A>
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:

119     A new movie by Dimitris Menemenlis and Chris Henze shows ice dynamics
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
123     href="/movies/ice_03.mpg"> here</a> (this one is 91MB!). A set of web
124     pages with summary information regarding MITgcm simulations being
125     carried out in the ECCO high resolution global ocean state estimation
126     initiative can be found <a href="http://ecco2.org/">

138     A spectacular movie by Chris Henze of NASA AMES beautifully captures an
139     eddy permitting expanded cube sphere MITgcm simulation being carried out,
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.
