Data Notes

The information contained here is of interest to anyone using the U.S. GLOBEC Georges Bank on-line data system. It contains problem reports, time-critical data notes and other transient information about the on-line data. It should be checked periodically for new items.

Trouble accessing satellite images

The computer system that houses the satellite images is moving from NOAA to GSO. Images should be available as soon as the move is complete.

Trouble accessing satellite images

There is trouble accessing the satellite image data server. I will correct the problem as soon as possible. Sorry for the inconvenience. Fixed: April 30, 1997

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.

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.

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 with underlines.

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.
