Some Satellite Images Unaccessible
Glenn Strout at UMass/Dartmouth wrote: "Currently one of our
network machines is down due to a disk crash. Our system manager
isn't due into the office until next week. URI recently installed a
firewall which has prevented us from downloading the daily images.
Welcome to 2000! We should have these problems resolved by the end
of next week."

New ISP for URI (from Robert Sand <email@example.com>)
Today, the Network and Telecomunications group in Kingston
sucessfully changed URI's Internet Service Provider (ISP) from Verio to
MCI. You may notice that accessing sites on the Internet is quicker, this
is due to the new service and takes advantage of MCI's position as one of
the largest Internet backbone providers.
You may also encounter some problems with people connecting to
URI. This temporary problem is related to the time necessary for the
change in ISP to be broadcast around the Internet so that other peoples
computers relearn how to get to URI. It should pass shortly.

Broad Scale average temperature and salinity
Every GLOBEC Broad Scale cruise report has included a table with the
average temperature and salinity in the surface layer (0-30m) for four
regions of Georges Bank. An error has been found in the routine that
selected which stations to include in a region (in effect, shifting
the search area up to a few tenths of a degree south - enough to pick
up or drop a station or two).
The average values for each survey were recalculated - this time
using the correct areas and using the final processed CTD data,
including the data from the intermediate Bongo stations (which were
not included in the previous calculations). The values didn't change
much - the seasonal and the interannual variability looked pretty much
the same - but the numbers were different.
The Bank-wide average fluorescence for each survey (not presented in
the cruise reports, but shown at a few meetings) also was
Sorry for any inconvenience this may have caused. And thanks to
Charlie Miller and Jen Crain for recognizing that there was a problem.

UTC/local time conversion utility has "round-off" error
The utility that we use to convert between local time and UTC (aka GMT)
time has a 1 minute round-off error under certain conditions. We
have seen this problem in the meteorological data from several Endeavor cruises.
The error is evidenced by a one minute mismatch between the "year day"
parameter value and the local date/time parameters. We are working to
fix this problem, and will let you know when the fix is in place.
Note: This problem has been fixed as of July 22, 1998.

J. Bisagni's satellite images unavailable starting Thursday, July 2.
Tim Mavor at URI said that his computer, chips1.gso.uri.edu,
will be having a system upgrade starting on Thursday, July 2.
Hence, any data served off of this machine, like Jim Bisagni's OI
images, or his AVHRR data for Georges Bank, will be unavailable
during that time. He will keep us updated as to when *exactly* this
will be occurring, and when he expects chips1 to be up and serving

MET 1 Hour Data Removed - needs reprocessing *UPDATE*
The one hour averaged meteorological wind direction data for 1995
has been corrected and is back on-line. We are still working on
the 1996-present data. As these data files become available,
they will be placed on-line. If you have any questions
contact the Data Management Office.
Addendum: all data have been reprocessed and corrected as of April 1998.

New JGOFS Software Available
The new JGOFS software
release, version 1.5 is being used by the U.S. GLOBEC Georges
Bank home page. The data directory has a new look, with listing,
display and other options available via buttons at the top of each
data page when these are available. The data objects are located
near the top of the page and the directory of available objects is
moved to the bottom of the page. Since this is a new release
and some bugs may yet be uncovered, please report any problems you
have to the Data Management Office.

New "options server" in use
As of today, the globec system will handle most of the "Other options"
tasks when dealing with data accessed from the U.S. GLOBEC Georges Bank
data server. Previously, these tasks (such as making x-y plots, or
formatting data for use my Matlab) were done by puddle. The new
server is a faster processor, so performance should improve.
February 4, 1997
NMFS/Woods Hole CTD data served with corrupted data lines
Several CTD data sets served from the NMFS/Woods Hole data server appear
with corrupted data lines. These show up as either missing values, or
what look like multiple data lines concatenated together. We are
looking into this problem and will correct it as soon as possible.
Update: This problem was fixed as of February 19, 1997 when the
jgof.wh.whoi.edu server took over for the whsun2 server.
November 20, 1996
NMFS/Woods Hole data temporarily unavailable
The NMFS/Woods Hole data server is moving to another platform so their
data are temporarily unavailable. [As of ~1500 the data are available.]
Georges Bank Central Server unavailable due to upgrades
The U.S. GLOBEC Georges Bank central data server and Web site will
be unavailabe Thursday, January 25, 1996 and again in early February
in order to upgrade its operating system to Solaris 2.5 and hardware
(more memory and disk space.) Please contact the Program Office if these scheduled times are inconvienient.
Correction to wind speed units in the thesaurus(Bob Groman)
The thesaurus incorrectly listed the units for various wind
speeds as knots. The units should have been in meters per second.
The thesaurus has been corrected as of today.
The defexec method (Bob Groman)
The defexec method is very flexible in that it can be used both to
execute scripts and programs as well as open up lower level
data files just like the def method can do. It uses the presence of
double quotes ("...") around data values to suppress creating a hypertext link
to the next level. Blanks can appear within the text enclosed within
the double quotes. However, if you do want to create a link (and
therefore do not use the double quotes) do not include any
blank spaces in the text string. If you do, the link may not work.
This is because a selection at the next level is being made and
selection does not handle blanks. As a work-around, replace the spaces
Hydrographic data contour plots (David Mountain)
A problem has been identified with some of the contour plots of
hydrographic data in the Broad Scale cruise reports. For plots
of bottom values, to be considered a bottom value the deepest
observation in a cast had to be within 10m of the bottom where
the depth was < 100m and within 25m where > 100m. If not, the
station was not included in the contouring. The problem is that
all station locations were posted on the plots, whether a bottom
value existed or not. The deep stations off the bank (7, 16, and
29) do not have bottom values, are not included in the
contouring, but their locations are posted. If they were
included, the southern boundary of the Bank would be ringed by
higher temperature, salinity and density contours.
This will be corrected in future plotting - by posting only those
stations with bottom values.
Thanks to Bob Houghton for recognizing the problem.
