Ocean observation data from Woods Hole Oceanographic Institution ships Oceanus, Knorr, and Atlantis, in world-wide oceans from 1993-06-26 to 2011-08-05

The cruise data sets consist of directories, each of which may contain scientifically valuable data from the cruise. The main identified directories and the data they contain are listed below. Each cruise data set may contain one or more of the following (note that the directory names are all capitalized here; in the cruise data set they may be all capitalized, all lower case, or a combination):

Meteorological and thermosalinograph:

ATHENA90 - contains meteorological data from the IMET (Improved Meteorological Package), which includes the following: SST, air temperature, wind speed, wind direction, barometric pressure, solar radiation, long wave radiation, humidity, precipitation, aerosol levels, sea surface conductivity (salinity). Comment: This is the same information found in ATHENA and/or CALLIOPE in a special format.
ATHENA - see ATHENA90. This is the same information, in another format.
CALLIOPE - see ATHENA90. This is the same information, in another format.
ATHENA99 - same as ATHENA90.

Currents:

ADCP - Acoustic Doppler current profiler, measures current speed and current direction.
ADCP75 - same as ADCP, different format (including binary).
ADCP_DATA - same as ADCP

Hydrographic profiles:

CTD - Conductivity-Temperature-Depth. Measures profiles of ocean temperature, salinity, pressure and sometimes oxygen, transmissivity, and fluorescence. These data may be in a processed form (ASCII CSV format) or unprocessed binary files (output from the Seasoft software).
SIPPICAN_XCTD - same data as CTD, different format (including binary).
XBT - Expendable bathythermograph, used to measure ocean temperature profiles. The type of XBT is noted in individual files. These data may be in the form of processed ASCII files or binary files.
XCTD - Expendable bathythermograph, used to measure ocean temperature and salinity profiles. Has the same ASCII and binary format as XBT data.
SALT-O2 - Salinity and dissolved oxygen measurements from salinometers and oxygen titration hydrographic analysis instruments.
MOCNESS - Multiple Opening and Closing Net, with an Environmental Sensing System: sensors report conductivity (salinity), temperature, depth, and chlorophyll, oxygen and light levels.

Bathymetry:

CENTERBEAM - SeaBeam multibeam echosounder, bathymetric and sidescan data.
SEABEAM - SeaBeam multibeam echosounder, bathymetric and sidescan data.
KNUDSEN - Knudsen echosounder for measuring bathymetry.

Alvin submersible:

ALVIN - photographic stills from Alvin.
ALVIN_EXT_STILLS - photographic stills from Alvin.
ALV_EXT_STILLS - photographic stills from Alvin.
ALV_EXTERNAL_STILLS - photographic stills from Alvin.
ALVIN_EXTERNAL_STILLS - photographic stills from Alvin.
3### - (any directory 3000 - 3999) dive information from numbered dive of Alvin.
4### - (any directory 4000 - 4999) dive information from numbered dive of Alvin.
5### - (any directory 5000 - 5999) dive information from numbered dive of Alvin.

Gravity/magnetic field:

MAGNETOMETER - measurements of Earth's magnetic field.
MAGNETOMOETER - same as MAGNETOMETER
MAGNETICS - same as MAGNETOMETER
GRAVITY - measurements of Earth's gravitational field.
GRAVITY_DATA - same as GRAVITY

SCRIPTS - shared resources; shells.
DOCS - documents for cruise, instrumentation.
SCIENCE - miscellaneous documents saved to disk by science team.
SHIPTRACK - navigational information.
TERASCAN - satellite data uploaded from another source. They are not unique cruise data.

Cruise photographs:

CRUISE_PARTICIPANTS - photos and biographies of cruise participants.
CRUISE_PICTURES - cruise photographs.
PICTURES - photographs from cruise.
IMAGES - photographs.
