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.

Sargassum Surge: How Seaweed is Transforming our Oceans and Coastal Ecosystems
Until recently, Sargassum –a free-floating seaweed–was distributed throughout the Sargasso Sea , the north Caribbean Sea, and the Gulf of Mexico. But in the space of a decade, this seaweed has, as one scientist remarks , “Gone from a nonfactor to the source of a terrible crisis.” Driven by climate change, anomalous North Atlantic Oscillation in 2009-2010 and a glut of anthropogenic pollutants, sargassum has proliferated. Seasonally recurrent mats as deep as 7m now bloom in the “Great Atlantic Sargassum Belt” (GASB), which covers areas of the Atlantic from West Africa to the Caribbean Sea and Gulf of Mexico. Every year, millions of tons wash up along the shores of more than 30 countries . Dr.
