barnegat.sub - Records of daily water temperatures and salinity observations for the period Jan. 1958 - Feb. 1970. MBT (mechanical bathythermograph) slides read at 15 meter intervals by group at Woods Hole Oceanographic Inst. This file is data digitized from U.S.C.G. Oceanographic Reports by the Orkand company at NCDC in fall of 1998. Information regarding keying format can be found here. See list of U.S.C.G. Report Data above for actual depth of measurements and changes in locality and water depth of the Lightship and look here for more background information.
barnegat_sub.kle - Data from barnegat.sub, tab-delimited with fields labelled by K. Elder.
barnegat.ls
- Subsurface MBT (mechanical bathythermograph) data for the period
1956 - 1969 at 5 m intervals read
from an NCDC CDROM. The file was given to K. Elder by NODC liason George
Hiemerdinger. The records are not in chronological order. Information
for the format of this data can be found here.
Note:
Apparently there were two groups reading the mbt slides, one at Woods Hole
whose work was published in the Coast Guard Reports, and the other at NCDC.
The NCDC group seems to have read the slides at 5 meter intervals whereas
the WH group read them at 15 meter intervals.
barnegat.txt - tab-delimited file of barnegat.ls data with field names and sorted by K. Elder.
barnegat.tdf11 - Meteorological records (rsz=140 - TDF-11 sfc marine) ftpd from NCDC October 1997 via Joe Elms for the period 1961 - 1970. These data were part of the "New York Bight Study" and were merged into COADS data.
The data collected and
keyed at NCDC for the New York Bight Study were originally placed into
the TDF-11 format with a few modifications. Deviations from the TDF-11
format for this file are that in positions 78-79 in place of the Ocean
Weather Station Number (OSV - Ocean Station Vessel) or Country Code they
placed the last two digits of the ship number (e.g. Ambrose, 0501). Also
in position 81 (OSV or ship indicator), a blank, 9, or 0 appears, the 9
always appears with 1960's data and 0 from the 1970's. Documentation for
the TDF-11 format is not available digitally.
Overpunches occur in this
set and generally indicate a negative value. They are usually an
11 punch over a number which gets converted to a letter in a printout or
for screen viewing. e.g. a letter J represents a negative value
over a 1 , a K =-2, L= -3 ........Q=-8, and R = -9. An 11 punch
over a 0 is generally not converted and what you see is a blank character,
sometimes it appears as a left-handed brace (you may have to examine these
punches in hex to see what was actually punched).
The perl script tdf11.perl
and awk script jday.awk
can be used to convert this format into a labelled, delimited matrix. A
description of the fields produced with these scripts can be found here.
