HOT Physical Oceanography Thermosalinograph data
Entry ID: UH_THERMOSAL_HOT


Summary
Abstract: Scientists working within the Hawaiian Ocean Time-series (HOT)
project, "http://hahana.soest.hawaii.edu/", have been
making repeated observations of the hydrography, chemistry and biology
at a station north of Hawaii since October 1988. The objective of this
research is to provide a comprehensive description of the ocean at a
site representative of the central North Pacific Ocean. Cruises are
made approximately once a month to Station ALOHA, the HOT deep-water
station (22 45'N, 158W) located about 100 km north of Oahu,
Hawaii. Measurements of the thermohaline structure, water column
chemistry, currents, primary production and particle sedimentation
rates are made over a 72-hour period on each cruise.

Thermosalinograph data have been obtained since cruise HOT-63 using a
SBE-21 Seacat thermosalinograph system. Data are recorded
every 10 seconds from water collected by a continuous seawater system aboard
R/V Moana Wave from a depth of about 3 meters. These data are processed and
quality controlled. Details of the thermosalinograph processing can be
found in HOT Data Report #7 (see the file Readme.first for information
on how to obtain the Data Report).

Data consist of time, temperature and salinity for
every sample interval recorded. Error flags for temperature and salinity were
incorporated to each data record beginning with cruise HOT-72. Details
of this format are given in the file `Readme.ts.format'. The data
records are written so that they can be read with a simple FORTRAN
read statement.

Navigation data are also included in the thermosalinograph data file.
The navigation data are recorded every minute from the Global
Positioning System (GPS) aboard R/V Moana Wave and linearly interpolated at the
same times of the thermosalinograph record. These data include latitude and
longitude. Data exist in ASCII files which can be read by all
users. There is one file per cruise containing the thermosalinograph
and navigation data. The file name is based on cruise name and
number. Thus, hot63ts.dat contains the data from HOT-63. Data file names
from ALOHA-Climax (AC) cruises have the prefix ac,e.g. ac1ts.dat
contains data from AC-1 cruise.

The continuous flow of these data depends on funding, and that depends
in part on the credits that we get from the data users. If
you use these data in your project, please contact Dr. Roger Lukas to
avoid possible duplication of efforts. Please consider the
benefits of possible scientific collaborations in the analysis of
these data. If you use our data in your project, we would appreciate your
acknowledgement of the HOT project.The following NSF grant number
should be cited in publications: OCE-9303094. A preprint and reprint
of the publications utilizing HOT data would be appreciated.
