The TD-Diver is based on an ingenious and proven concept and is acknowledged as the most reliable instrument for the 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.

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.

For as long as humans have inhabited Europe’s Atlantic coast, the ocean has been a great source of wonder and mystery. History is full of fascinating tales of epic endeavors, new discoveries of fearless explorers, fishing communities inextricably linked to the bounties of the sea, cultural interactions both peaceful and not, and voyages that went awry during monumental storms or simply due to bad luck. 
 
In the south of Spain, at the boundary between the Atlantic Ocean and the Mediterranean Sea, one such tale involves a long-lost merchant ship that went undiscovered from the 16th century until 1984. Believed to be carrying valuable goods from Italy, it sank just across from Gibraltar in the Algeciras Bay at a point called La Ballenera.
Read MoreStaying Within Budget: Carbon Planning
While we usually concern ourselves with budgeting money or time, we should be thinking about another type of budget: the carbon budget. The carbon budget refers to the amount of carbon exchange, especially carbon dioxide, allotted on an annual basis to prevent the earth from reaching an increase of 2-degrees Celsius all over the globe. If a 2 degree increase does occur, global warming effects are expected to be catastrophic and irreversible. 
 
In order to know how close we are to reaching the carbon budget, an extensive knowledge of types of carbon input and their magnitudes, as well as their fluctuations over time, is needed.
