We have compiled a 2km bathymetric grid for Lake Michigan to be used in
the EEGLE project.  The grid is based on a Lambert conformal conic
projection and the NGDC 9 arc second bathymetric data.  We have tried
to optimize the land-sea mask for hydrodynamic modeling purposes.
The depths are relative to IGLD 1985, so you may want to add a meter
or so to account for current lake levels.  We also compiled a vector
shoreline data set with a three level categorization of shoreline type,
i.e., shoreline classification, shore protection classification, and
subaqueous calssification.  These data sets are available on the EEGLE
web site at:

The first EEGLE cruise on the Lake Guardian is about to get underway
this week from Milwaukee.  I hope we see some resuspension and not
too much cold weather.

I will be attending the CoOP Science Steering Committee meeting in
San Diego right before the AGU Ocean Sciences meeting, Feb. 8-13.
If you have any issues you want me to bring up at that meeting,
please let me know.  If you are planning to go to the AGU meeting,
maybe we can get together there.

That's all for now.  Let's try to use the "eegle-mod@eegle.glerl.noaa.gov"
mail group to keep each other informed of our progress.

P.S.

Paul, I saw some indication of resuspension in satellite imagery from
12/14/97 and 12/27/97.  Any storms then?

Chansheng, If you want to use the new 2 km bathymetry with the version
of pomgl that we gave you, you will have to replace subroutines
rgrid, rlat, and rlon with the new ones on the web site.  Please let
me know when you have copied the pomgl stuff from the ftp site so I
can erase it to save space.

Keith,  If you can't access the files on the web site, let Greg Lang
know the IP addresses you want added to the list. We're still working
on the password access method.
