Oceanography
Instrumentation for Long-term, Stand-alone Monitoring
Campbell Scientific measurement and control systems provide remote unattended monitoring for a
variety of oceanographic applications. Accurate measurements, proven reliability, and the ability
to customize each station are a few of the features in which our systems are known.
From coastal weather stations to weather buoys to stations aboard ships, our systems are well-suited
for monitoring:
- Coastal erosion and sedimentation
- Ecosystem research
- Ice-flow movement (GPS)
- Ice-load/impact monitoring
- Oceanographic currents
- Salinity and water quality studies
- Ship-board monitoring
- Structural monitoring
- Temperature profiles
- Tidal monitoring
- Wave height and power
- Weather and climate monitoring
Oceanography Measurement System Benefits
- Measurement stations are customized to meet exact needs.
- Stations can measure most commercially available sensors without external signal conditioning.
- Communications options include satellite (Argos, OrbCom, QualComm, Inmarsat C, GOES), radio, phone,
and cellphone.
- Stations operate reliably in harsh environments.
- Dataloggers provide on-site statistical and mathematical capabilities.
- Batteries and solar panels allow long-term, remote operation.
- Stations are easily expandable-add new sites or add new sensors to existing sites.
- Powerful software supports programming, data retrieval, and data display.
Monitoring and Control
Our monitoring systems are based around programmable dataloggers
that measure the sensors, then process, store, and transmit the data. The compact size, rugged design,
low power use, and versatility of our dataloggers allow them to be used in many applications, including
integration into submerged systems. Our dataloggers have wide operating temperature ranges, programmable
execution intervals, and ample input channels for commonly used sensors. Most sensors interface directly
to our dataloggers, eliminating external signal conditioning. On-board instruction sets contain processing
routines that range from simple statistics (e.g., average, maximum, minimum, standard deviation) to more
complex routines (e.g., FFT, saturation vapor pressure, histogram).
Data are typically viewed and stored in the units of your choice (e.g., wind speed in mph, m/s, knots).
Measurement rates and data recording intervals are independently programmable, allowing calculation of
15-minute, hourly, and daily data values from 1-minute or 1-second measurements, for example. Conditional
outputs, such as wind gusts, can also be recorded. The program can be modified at any time to accommodate
different sensor configurations or new data processing requirements. If needed, channel capacity can be
expanded using multiplexers. All of these features allow you to meet your data requirements, whether it's
storing hourly averages of meteorological data or compensating a depth sensor for depth and wave period to
produce wave power spectra.
Sensors used for Oceanography
Almost any sensor can be measured by our dataloggers, allowing systems
to be customized for each site. Typical sensors used include, but are not limited to: wind speed and
direction, solar radiation, temperature (air, water), relative humidity, precipitation, barometric pressure,
pressure/depth (strain gage or quartz crystal), as well as flow transducers, potentiometers, load cells,
accelerometers, radiometers, thermocouples, thermistors, and RTDs.
Data Retrieval
We offer multiple communication options for data retrieval, which can be
mixed within the same network. Telecommunications options include satellite (Argos, OrbCom, QualComm,
Inmarsat C, GOES), telephone (landline, cellular, voice-synthesized), radio, short-haul, multidrop, and
ethernet. On-site options include storage module and laptop.
Software
Our PC-based support software simplifies the entire monitoring process,
from programming and data retrieval to data display and analysis. Our software automatically manages data
retrieval from networks or single stations. Robust error-checking ensures data integrity. We can even
help you post your data to the Internet.
