Overview
The Van Essen ceramic-shelled Cera-Diver is designed for monitoring groundwater under potentially corrosive conditions, such as brackish water and seawater, requires a robust and durable datalogger. The ceramic-shelled Cera-Diver is designed specifically for such environments. This highly reliable and compact Diver measures groundwater levels with a typical accuracy of +/-0.05% full scale. The Cera-Diver is equipped with a memory for 48,000 measurements per parameter.

 Van Essen CTD-Diver Water Level & Conductivity Logger 
 
If you need to monitor groundwater levels and saltwater intrusion, injected wastewater, or contamination from chemical discharges and landfill sites, the CTD-Diver is a good choice. It features a rugged, corrosion-proof ceramic housing and is equipped with a four-electrode conductivity sensor to measure electrical conductivity from 0 to 120 mS/cm. There are two options for measuring conductivity: true or specific conductivity at 25 degrees Celsius.

The Port Everglades in Broward County, Florida, serves large trade vessels and cruiseliners and incoming and outgoing recreational boaters. However, as cargo ships become larger, the port must expand. 
 
A dredging project led by the US Army Corps of Engineers will substantially deepen and widen the port's navigation channel to accommodate larger Panamax cargo ships and modern cruise liners. 
 
As a result of this project, a large amount of sediment will be displaced into the water column. This suspended sediment may settle outside of the project area, burying benthic organisms like corals, and possibly carrying harmful particulates to other regions.
