Water Quality Monitoring System

LOBO Land/Ocean Biogeochemical Observatory

The ultimate answer to the need for automated, robust and accurate water quality measurements, particularly in sensitive and diverse ecological areas such as estuaries and inland waters.
LOBO (Land/Ocean Biogeochemical Observatory) is a complete turn-key water quality monitoring system that addresses the need for routine, robust and accurate water quality measurements, particularly in sensitive and diverse ecological areas such as estuaries and inland waters. Developed by Satlantic in collaboration with MBARI, the Sea-Bird Coastal LOBO is designed to create a real time sensor network for aquatic systems.
 
LOBO comes complete with instrument frame, optional floating platform, power and wireless telemetry system, integrated sensor suite, automated processing software and web based data visualization/display software.
 
Parameters measured by the LOBO include: 
  • Physical: temperature, depth, salinity (optional), current profiler (optional) and turbidity.
  • Chemical: chromophoric dissolved organic matter (CDOM), nitrate, and dissolved oxygen.
  • Biological: chlorophyll fluorescence with options for additional ancillary pigments.
System Features:
  • Easy to install and operate for both rapid and long term deployments.
  • LOBOviz software package for real-time and archived data viewing through a simple web based interface.
  • Highly robust, accurate and stable sensor packages with fully integrated and proven anti-biofouling systems.
  • Floating platform available in shallow (RiverLOBO) and deep water (BayLOBO) configurations.
  • Platforms also available for attaching to fixed structures (DockLOBO) or placing directly on the bottom (BenthicLOBO).
Talk to us about your applications to find out how this innovative system can meet your most demanding monitoring requirements.

In Situ Nutrient Monitoring in the Murderkill Estuary

Background:

The Murderkill watershed is located in southern Kent County, Delaware and has a drainage area of approximately 270 km2. Based on a 2002 assessment, the land use in the watershed is predominantly agricultural (55%)  but like many coastal watersheds the amount of urban and residential development (14%) is increasing (Delaware  Department of Natural Resources and Environmental Control (DNREC 2005).
