Water Quality Monitoring

Real-Time Monitoring
Effective water quality monitoring for ecosystem management requires frequent and spatially dense measurements available in near real time. A transition from hand-sampling to automated monitoring will deliver this higher resolution of data needed to better understand the ecosystem. In an effort to make automated water quality monitoring accessible to the conservation and resource management communities, the Ocean Research & Conservation Association (ORCA) has developed the ORCA Kilroy™ Network.

The Kilroy Network
The ORCA Kilroy Network consists of a wireless network of remote semiautonomous sensor systems. This is coordinated by a central supervisory system that directs operations of the remote systems, collects data, and relays them via the Internet through a standard web service interface to a database in near real time. The coordination and data transfer are presently over cellular Internet connections on a wide scale and cabled connections at the station scale. View Larger Image

Remote Subsystems
To date, four remote subsystems of the ORCA Kilroy network are in use:

1) a sensor suite measuring flow speed, flow direction, package orientation, water temperature, water level, wave height and wave period

2) a GPS/power/telemetry unit;

3) a network interface unit to simplify off-the-shelf sensor integration into the network

4) a flow-through bathyphotometer to provide a direct biological measurement of bioluminescence intensity.

Each subsystem is integrated at the component level to
lower cost, reduce size, and improve efficiency, sharing the communications infrastructure and power from a solar-charged battery.

"ORCA’s Kilroy is
brilliant. The whole concept of a low-cost monitoring network is critical for understanding the ocean so we can better protect it.
- Sylvia Earle, Ph.D.

The High Seas -- areas of the ocean beyond national jurisdiction -- cover almost 50 percent of the Earth's surface. They are the least protected part of the world.
