Where there is a need to monitor groundwater levels and saltwater intrusion, injected wastewater, or contamination from chemical discharges and landfill sites, the CTD-Diver with its rugged, corrosion proof ceramic housing, is the instrument of choice. The CTD-Diver is equipped with a four-electrode conductivity sensor that measures electrical conductivity from 0 to 120 mS/cm. There are two options for measuring conductivity: true or specific conductivity at 25 degrees C. Additionally, pressure and temperature are measured and recorded.

Questions & Answers
What software is needed for the CTD logger?

Diver-Office is a free software that can be downloaded on the Van Essen website. You can use the software to export data reports, visualize data and change logger settings.

How many measurements can the CTD Diver hold?

The memory capacity for the logger is 48,000 measurements.

Does the CTD diver need calibrated prior to use?

The logger is factory calibrated for temperature, pressure and conductivity prior to shipment. To calibrate conductivity in the field, a 2-point calibration (dry air/standard) can be performed to ensure accurate readings and a 4-point calibration will bring the logger up to specifications for the full-measurement range for conductivity.

Restoration, Testing, Research and Education

A few years after Ohio became a state in 1803, George Harner arrived in Greene County with a land deed signed by then-President Thomas Jefferson and Secretary of State James Madison. The homestead was largely old forest and wetlands and also included a fen-fed stream—the Beaver Creek. As was the case with much of the Ohio Territory, the forests eventually gave way to land clearing and grain farming. Harner’s descendants, including his son John and John’s wife, Sarah Koogler, continued to work the rich soil for many years to follow. Much of the original property and surrounding land has fallen prey to urban sprawl.

Storms Cause Extended, Elevated Contaminant Concentrations in Urban Streams

Each fall in Puget Sound, coho salmon leave the salt water and swim up freshwater streams. They head upstream to spawn: lay their eggs and die. Death is always the end of this journey for coho salmon, but in streams now running through urban areas, stormwater runoff kills them before they can spawn. This phenomenon, called Urban Runoff Mortality Syndrome, can kill up to 70-90% of coho salmon in an affected area. “‘Woah’ is a pretty common response,” said Kathy Peter, a research scientist formerly at University of Washington Tacoma and the Center for Urban Waters. This phenomenon adds pressure to the Puget Sound population, already considered a species of concern by the United States Fish and Wildlife Service under the Endangered Species Act.
