Overview
The Van Essen CTD-Diver works wherever there is a need to monitor groundwater levels and saltwater intrusion, injected wastewater, or contamination from chemical discharges and landfill sites. 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.

Van Essen Diver-Link Cellular Telemetry System with Diver-Hub
The Van Essen Diver-Link Cellular Telemetry System enables professionals to monitor water level, conductivity and temperature readings from their home or office. The near real-time data allows scientists, managers, and other environmental professionals to monitor flood events, well depths and groundwater levels. 
 
 Long-term monitoring allows users to develop trends on ever-changing climate conditions. The Van Essen Divers ( CTD-Diver, Cera-Diver, TD-Diver and Mirco-Diver) work well for monitoring water supply, tailing ponds, dewatering, contaminant plumes and hazardous waste storage sites . 
 
 The Diver-Link allows users to monitor groundwater via the Diver-Hub Web Portal for real-time management of site data, equipment and water levels.

While human infrastructure, urbanization, and industrialization have advanced human societies, the natural environment has suffered due to constructed impediments and deteriorating architecture. In order to combat this degradation, habitat restoration programs across the US work to remove impairments and improve damaged waterways.

In the far north, the Alaska Peninsula stretches away from the Last Frontier into the Pacific Ocean. A narrow strip of land dotted with freshwater lakes and intruded upon by ocean inlets–this unique region is intimately connected with the surrounding water. 
 
Nestled halfway down the peninsula's southern coast are the small villages of Chignik. The area has historically been home to the Aleut people and has been heavily reliant on fishing for centuries. 
 
Home to commercial and subsistence fishing today, Chignik continues to rely upon the salmon returns to the surrounding villages, which are supported by scientists working tirelessly to understand and steward these fish populations.
