Evans-Hamilton, Inc. (EHI) can assemble an 
oceanographic monitoring buoy custom-built to suit your 
needs. These Oceanographic Data Buoys (ODB) serve a 
variety of needs, including: 

• Oceanographic and meteorological research 
• Weather forecasting 
• Marine forecasting 
• Assistance to fisheries 
SERVING YOU WITH SOLUTIONS 

The ODBs are solar powered and can accommodate a 
variety of instrumentation systems depending on the 
project requirements. They can be integrated with a radio, 
cell phone, or satellite telemetry system to allow real-time 
transmission of data to a shore station. Additionally, 
acoustic modem telemetry allows direct communication 
with bottom-mounted instrumentation (wave and current 
gages). 


The buoys have been designed for long-term deployments 
with minimal servicing requirements. The standardized 
electronics chassis allows easy access to instrumentation 
during servicing, when required. In addition, the 
subsurface instruments on the buoy (water quality sensors, 
acoustic modem), are installed to allow for easy recovery 
and servicing from the topside of the buoy. 

Satellite tracking of the ODB is available, which continually 
monitors the buoy’s position and notifies the client via email 
if the buoy drifts outside of a user-defined area.
