Two primary datasets are created on each cruise: JGOFS and MGD77.
The data processing scripts used to produce JGOFS and MGD77 data
sets create a number of intermediate files. These files are included on the data distribution media in a
file called 0701proc. They are included to make re-processing easier in the
event of an error, but no extensive detail of the formats is included in this
document. For information, please contact itvessel@usap.gov.
The JGOFS data set may be found on the distribution media in the
file /process/0701JGOF.tar. The
archive contains one file produced for each day named jgDDD.dat.gz, where DDD
is the year-day the data was acquired. The “.gz” extension indicates that the
individual files are compressed before archiving. Each daily file consists of
22 columnar fields in text format as described in the table below. The JGOFS
data set is created from calibrated data decimated at one-minute intervals.
Several fields are derived measurements from more than a single raw input. For example, Course Made Good (CMG) and
Speed Over Ground (SOG) are calculated from gyro and GPS inputs. Daily plots
during the cruise are produced from the JGOFS data set. Note: Null, unused, or unknown fields are
indicated as “NAN” or 9999 in the JGOFS data.

The MGD77 data set is contained in a single file for the entire
cruise. It can be found in the top
level of the distribution data structure as NBP0701.mgd. The file NBP0701.gmt is created from
the MGD77 dataset using the “mgd77togmt” utility. NBP0701.gmt can be used with the GMT plotting package.
The data used to produce the NBP0701.mgd file can be found at the
root of the distribution media and in the file /process/0701proc.tar. The data files in the archive contain a
day’s data and follow the naming convention Dddd.fnl.gz, where ddd is the
year-day. These files follow a space-delimited columnar format that may be more
accessible for some purposes. They contain data at one-second intervals rather
than one minute and are individually “gzipped” to save space. Below is a
detailed description of the MGD77 data set format.
All decimal points are implied. Leading zeros and blanks are
equivalent. Unknown or unused fields
are filled with 9s. All
“corrections”, such as time zone, diurnal magnetics, and EOTVOS, are understood
to be added.

The ADCP system measures currents in a depth range up to 1200 m
(OS38 in deep profiling mode). In bad weather, ice, or unfavorable sea state
the range is reduced, and sometimes no valid measurements are made. ADCP data collection is the OPP-funded
project of Eric Firing (University of Hawaii) and Teri Chereskin (Scripps
Institution of Oceanography). Data
is collected on both the LMG and the NBP for the benefit of scientists on each
cruise, and for the long-term goal of building a profile of current structure
in the Southern Ocean.
Matlab “.mat” files containing current contour and vector data
have been placed in the file /adcp/0701MAT.tar.
Please note that these files must be considered preliminary only.
Data are not a “final product” until post-processing has been performed by the
principal investigators. For more information on data format, post-processing,
and for data download, please visit: http://currents.soest.hawaii.edu.
A data feed is sent
from the ADCP system to RVDAS whenever a reference layer is acquired. This feed
contains east and north vectors for ship’s speed, relative to the reference
layer, and ship’s heading. This data is saved in files located in 0701adcp.tar in the directory /rvdas/nav.
The NBP carries a pCO2 measurement system from
Lamont-Doherty Earth Observatory (LDEO). pCO2 data is recorded by RVDAS and
transmitted to LDEO at the end of each cruise. pCO2 data is archived in the
file 0701pco2.tar in the /process directory, which contains the
pCO2 instrument’s data merged with GPS, meteorological and other oceanographic
measurements. For more information
contact Colm Sweeney (csweeney@ldeo.columbia.edu).
During the cruise, eXpendable BathyThermographs were
used to obtain water column temperature profiles. XBT profiles allow
corrections to the sound velocity profile for the multi-beam system. The data files from these launches are
included as 0701xbt.tar in the /ocean directory.
During the cruise, CTDs were used to obtain water column Conductivity,
Temperature and Depth profiles. The
data files from these launches are included as 0606ctd.tar in
the /ocean directory.
The Research Vessel Data Acquisition System (RVDAS) was developed
at Lamont-Doherty Earth Observatory of Columbia University and has been in use
on its research ship for many years.
It has been extensively adapted for use on the USAP research vessels.
Daily data processing of the RVDAS data is performed to calibrate
and convert values into useable units and as a check of the proper operation of
the DAS. Both raw and processed data sets from RVDAS are included in this data
distribution. Quality-control plots for most instruments are created daily, and
may be found in postscript format in the file /process/0701QC.tar. The tables
below provide detailed information on the sensors and data. Be sure to read the
“Significant Acquisition Events” section for important information about data
acquisition during this cruise.
RVDAS data is divided into two general categories, underway and navigation. Raw data will be found
on the distribution media as subdirectories under the top level rvdas
directory: /rvdas/uw,
and /rvdas/nav.
Each instrument or sensor produces a data file named with its channel ID. Each data file is g-zipped to save
space on the distribution media.
Not all data types are collected every day or on every cruise.
The naming convention for data files produced by the sensors and
instruments is: NBP[CruiseID][ChannelID].dDDD. Example: NBP0701met1.d365.
· The
CruiseID is the numeric name of the cruise, in this case, NBP0701.
· The
ChannelID is a 4-character code representing the system being logged. For example the meteorology designation
is “met1”.
· DDD
is the day of year the data was collected.

Data is received from the instrument system via RS-232 serial
connections. A
time tag is added by RVDAS at the beginning of each line of data in the form,
yy+dd:hh:mm:ss.sss [data stream from
instrument]
where
yy = two-digit year
ddd = day of year
hh = 2 digit hour of the day
mm = 2 digit minute
ss.sss = seconds
All times are reported in UTC. The delimiters that separate fields in the raw data files
are often spaces and commas but can be other characters such as : =
@. Occasionally no
delimiter is present. Care should
be taken when reprocessing the data that the field’s separations are clearly
understood.
In the sections below a sample data string is shown, followed by
a table that lists the data contained in the string.

Seismic MSC Data From Cruise NBP0701
These data were recorded in the western Ross Sea, Antarctica, in
and around
the Adare Trough as part of the NSF Projects OPP-0440923
(Caltech) and
OPP-0440959 (Scripps) entitled "Collaborative Research: The
Connection
Between Mid-Cenzoic Seafloor Spreading and the Ross
Embayment". The PIs for
the survey are Steve Cande (Scripps) and Joann Stock
(Caltech). The data were
recorded as part of the cruise NBP0701 on the RVIB Nathaniel B.
Palmer, from
late Dec, 2006 through Jan, 2007. Multibeam, gravity, magnetics,
XBT and some
dredging samples were also acquired on the cruise.
The seismic equipment consisted of:
Data: The data are 8-sec records
with 2 mil (0.002 sec) sample rate.
The
cycle time on the guns was 12 sec.
The ship speed while
recording
was kept close to 4.5 kts, which gave an intershot
spacing
of approximately 27.8m. The data
are in little-endian,
IEEE
float format with ascii line-headers. The shot-coords are
given
in floating milli-arcsecs lat/lon in the trace headers.
Line
13 has a 12 sec record length (2 mil) and a 15 sec cycle
time
(34.6m). Lines 14 and beyond have a 12 sec record length
and
a 16 sec cycle time (37.1m).
Source:
6 GI guns, towed in a line with the closest 31m from the stern
of
the ship and the midpoint 43m. The guns are identical and
each
have a capacity of 225 cu in. The gun depth is 2m.
Starting
Line 13, the source is an array of 6 Bolt air guns
850/500/350/200/145/80
with a total of 2125 cubic inches.
Streamer:
48 channel, oil filled streamer with 12 birds. The closest
channel
(channel #1) is 150m behind the stern and the
interchannel
spacing is 25m. The streamer depth is 10m. Note
that
channel 37 is dead, and through cross-talk picks up the aux-1 channel.
Recorder:
OYO/DAS-1 fixed gain recorder with 48 channels, plus 2 aux
channels. The data are converted on the fly to
SEGY-format.
Sonobuoys:
Approximately 30 sonobuoys were deployed. The successful
ones
were usually the 57B-type and generally were live for 2
or
more hours (16 km). The sonobuoy data has regular 100 msec
burst
noise that is thought (but not verified) to be due the
transmission
of digital information from the sonobuoy.
Some
of the sonobuoys recorded at the beginning of the lines are
only
partially recorded (farther offsets) because the were
launched
for mammal monitoring purposes approximately 1/2 half
hour
before the seismic guns were started.
The sonobuoy data
is
on AUX-1 and also usually on AUX-2. A list of the good
sonobuoy
data is given in an accompanying file.
The data were recorded on a sequence of lines that are often
back-to-back with
only a few shots missing between them. Within each line the files
are broken
into a number of segments to keep the maximum file size < 2
Gbytes. Each
segment has it own line and reel header.
MCS LINES
A list of the lines is given below.
For each line the starting and ending shot number, lon-lat, and
date are given.

Sonobuoy
Info
Integer numbers are shot points. The first line for each sonobuoy
indicates
the release point and hence its nominal position. The second is the end of
the useful signal. "Mammal/partial" indicates that only
farther offsets are
present because the air guns were not active during the initial
1/2 hour of
deployment. In this
case, the first entry indicates when the guns were turned
on, no the position of the sonobuoy.
