Overview
The Van Essen TD-Diver is a reliable instrument for autonomous measuring and recording of groundwater level and temperature. Its internal memory of 72,000 measurements per parameter provides sufficient capacity to perform nearly one measurement every hour for 8 years. A new backup memory feature enhances data integrity. For each measurement, the Diver registers the date and time, groundwater level, and temperature.
Precision
The Van Essen TD-Diver is an easy-to-use datalogger featuring state-of-the-art electronics and a robust high-precision pressure sensor for long-term accuracy. The absolute pressure sensor requires minimal maintenance and re-calibration.
Applications
- Monitor potable water recharge areas for water supply
- Monitor tailing ponds, dewatering activities and water supply levels of mines
- General site investigations for construction
- Contaminant plume monitoring on spill sites, remediation sites, chemical storage facilities
- Landfill sites and hazardous waste storage sites

Van Essen TD-Diver: Robust Level Logger Ups Data Efficiency
All sorts of applications employ groundwater level loggers. These are typically deployed in piezometers, and log measurements for as long as the project requires. For those environmental professionals looking for a more long-term solution, the new Van Essen TD-Diver groundwater level logger is a solid choice. The new groundwater level logger launched in November 2016 with an eye toward including improvements to make it an even more robust option for groundwater monitoring. Over the years, through customer feedback and other experiences, managers at the company had envisioned quite a list of things to add. Among these, there are a few that environmental pros could really find handy.

Monitoring Volcanic Activity in Hawaii: Safeguarding Public Safety with the Hawaiian Volcano Observatory
The eight main Hawaiian Islands are made up of 15 volcanoes, six of which are active as of 2023 . Many locals live on or near an active volcano, making the monitoring and understanding of volcanic activity a core issue of public safety on the islands. Organizations like the Hawaiian Volcano Observatory (HVO) have spent decades monitoring the islands’ volcanoes to protect the public, develop a deeper understanding of the islands’ volcanos and forecast eruptions whenever possible. Even those who live away from edifices like Mauna Loa often have connections to the people living near the volcano.

Crystal Clear Problems: Impacts of Water Transparency in Aquatic Ecosystems
From crystal clear alpine lakes to muddy rivers and boggy swamps, water transparency is an easily observable water quality parameter to anyone who takes a few moments to peer into the (sometimes) murky depths. Water transparency varies dramatically based on the location of bodies of water among different watershed environments, but it can also change quickly due to a variety of internal and external factors. At Miami University (OH), the Global Change Limnology Lab explores the many ways that water transparency impacts aquatic ecosystems. Operational for nearly 20 years, the lab trains undergraduate and graduate students and has conducted work from the midwest Great Lakes to Alaska, South America and New Zealand. The Global Change Limnology Lab, headed by Dr.
