Complete Meteorological/Oceanographic
Data Acquisition and Telemetry Systems

Satellite Telemetry Buoy with INMARSAT-C

InterOcean's Meteorological/Oceanographic Data Telemetry Systems are modularly designed for unique applications and environments, either directly connected or telemetry linked where direct cable connection may not be possible or practical. These systems consist of one or more remote monitoring stations and central base data acquisition stations. One or two-way telemetry is employed to allow both transmission of data from remote instruments to a base station and transmission of commands from base station for changing the operation mode of the instrumentation.

The sensors for the systems can be mounted virtually anywhere. Some examples are: jetty, pier, lighthouse, offshore platform, buoy (surface and subsurface) and bottom-mounted installations. Also available are explosion proof and intrinsically safe designs for applications in extremely hazardous areas.

	Main screen of automatic data acquisition system, recording and displaying data from S4 with dual turbidity sensors, tide, and directional wave parameters, in addition to data from a surface wind speed and direction sensor.

Typical components from a harbor monitoring system, showing two wave/tide gauges, wind speed and direction sensor, short-range telemetry transmitter, computer acquisition system, and solar power system.

Top section (mast) of meteorological/oceanographic monitoring buoy. Underwater sensors for ocean current and wave measurement, in addition to surface sensors for wind speed and direction are incorporated. This instrumented buoy is used for real-time environmental and hawser tension monitoring at offshore oil terminals for vessel safety.

Mobile data receiver used with SPM telemonitoring system for offshore oil terminals (see above). This suitcase-sized receiver is enclosed in a portable waterproof case and used by harbor pilots for receiving real-time current and wind data to aid in navigating large vessels.

S4 with Argos telemetry buoy. S4 transmits current and CTD data at preselected intervals via Argos satellite.

Deployment of oceanographic monitoring buoy with acoustic modem for transmission of data to/from underwater sensors and INMARSAT satellite transmitter for worldwide communications to and from the buoy.

Shore-based telemetry transmitter connected to bottom-mounted tide gauge. This photo illustrates the small size and simple installation of telemetry components used for real-time data link.

Console-based data receiver shown with sensors. Sensors shown are for measurement of water current speed and direction, water temperature, tide, wind speed and direction, air temperature, relative humidity and barometric pressure. Analog signal conditioner, power system and displays are incorporated into the customer-specified cabinet. This photo demonstrates the ability to customize a system in exact accordance with any customer specification.

S4 sensor shown with underwater acoustic modem and transmitter. This S4 is internally configured for conductivity, temperature, wave and tide measurements. The low-power acoustic modem is located on the mooring rod directly above the S4.
