| R2R Data Types & Products | Home / Data Types & Products |
| Instrument | Description |
| ADCP | (acoustic doppler current profiler) sonar measures water current velocities |
| Anemometer | measures wind speed and direction |
| Barometer | measures atmospheric pressure |
| CTD | integrated hydro system measures conductivity, temp, pressure, etc. |
| Expendable Probe | hand/deck-launched single-use depth probes - XBT, XCTD, XSV, XCP, etc. |
| Flowmeter | measures rate of water flow - mechanical, optical, electromagnetic, etc. |
| Fluorometer | measures fluorescence (usually for phytoplankton) |
| GNSS | (global navigation satellite system) - GPS/WAAS, GLONASS, Galileo, etc. |
| Gravimeter | measures the Earth's local gravitational field |
| Gyrocompass | compass with a motorized gyroscope that tracks true north (heading) |
| HDSS | (legacy data only) (hydrographic doppler sonar system) sonar measures water current velocities |
| Hygrometer | measures moisture content in atmosphere, typically also includes air temperature |
| INS | determines spatial position and motion using inertial sensors with input from additional sensors (eg. satellite fixes) |
| Magnetometer | measures strength and/or direction of the Earth's local magnetic field |
| Met Station | logger/translator/display hardware unit that integrates data from several meteorological sensors |
| Multibeam Sonar | multiple formed beam echosounder (mapping sonar) |
| Nitrate Sensor | measures nitrate in water |
| Oxygen Sensor | (DO) measures amount of free oxygen dissolved in water |
| pCO2 | measures partial pressure of dissolved carbon dioxide |
| pH | measures acidic or basic value of seawater |
| PTU | measures any/all of barometric pressure, air temperature, relative humidity |
| Radiometer | measures radiation - pyranometer, pyrheliometer, pyrgeometer, etc. |
| Rain Gauge | (udometer) measures amount of liquid precipitation |
| Singlebeam Sonar | singlebeam ("profiling") echosounder used primarily to acquire bathymetry and/or subbottom data; may be fixed frequency or chirped |
| Speed Log | measures Doppler near surface vessel speed through water |
| Splitbeam Sonar | splitbeam ("fishfinding") echosounder used primarily to acquire water column imagery |
| SSV | sound velocity profiler - typically installed in seachest for multibeam |
| Thermometer, Air | measures temperature of air/atmosphere |
| Thermometer, Water | measures temperature of water (oceanographic thermometer) |
| Time Server | reads time from reference clock (GPS, WWVB, etc.) and distributes locally |
| Transmissometer | measures fraction of light absorbed, or scattered, by particles in water |
| TSG | (thermosalinograph) measures sea surface temperature, salinity, etc. near seawater intake |
| Ultra Short Baseline Positioning System | Systems dedicated to the positioning of subsea vehicles such as ROV and AUV. They are based on acoustic transmitted signals between one or several transponders and one acoustic antenna installed on a surface vessel. The transponders are mounted on the underwater vehicle or are fixed on the seafloor. These underwater acoustic positioning systems are coupled with inertial navigation systems. |
| Wave Radar | nautical X-Band radar measures wind waves and/or surface currents |
| winch | (legacy data only) measures wire tension, speed, payout, etc. |
In addition to near-real-time quality assessment of MET/TSG data produced by SAMOS, and post-cruise quality assessment of selected data types, R2R creates and serves a set of standard products for each cruise:
"Cruise-level" metadata record consisting of:
Expedition summary including:
Inventory of underway data sets including type, make, and model of each instrument system along with file format and release status.
Quality-controlled shiptrack navigation as a suite of files:
Original resolution (typically 1sec GNSS/INS), 1-minute resolution, and abstracted (minimized) set of “control points".
Scientific Sampling Event Log
The Event Log includes event numbers unique for the cruise, time, position, station and cast identifier as appropriate to the sampling event sampling instrument name (e.g. CTD, TM, MOC10), name of person responsible for the event, and a comment.
Post-processed data profiles for selected data types:
Geophysical trackline profiles (underway gravity, magnetics, bathymetry, etc) for vessels equipped with these instrument types; and Hydrographic profiles (depth, temperature, salinity, etc from CTD).
