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.

The Monterey Bay Aquarium Research Institutes Wireless Plan to Connect to MARS

Engineers and scientists that specialize in aquatic measuring practices always meet extra costs on the path to deployment. Maybe it is the corrosive nature of the saltwater, or the unbearable pressure tools must be equipped to handle while lying on the ocean floor. For anyone interested in hooking up with the MARS (Monterey Accelerated Research System) Observatory , which rests dozens of miles off the California coastline, the costs extend further. They get so high that only well-funded universities and governmental agencies can afford to connect with the underwater power and data hub. Hoping to lower that cost, engineers with the Monterey Bay Aquarium Research Institute ( MBARI ) constructed a wireless device called Deep-Sea Connect.

With Cameras and Artificial Intelligence, Fishing Vessels are Becoming Smarter

During an electronic monitoring conference in February, fisheries managers and fishermen watched a squiggly purple line meander across the screen. It was mapping the journey a tuna fish was taking, from being caught and landing across the deck of a fishing vessel. Leigh Habegger, executive director for Seafood Harvesters of America , a national commercial fishing group, said everyone in the crowd had their eyes glued to the screen. “It was fascinating, it was really cool,” she added.  The graphic was the manifestation of a machine-learning tool that was trained to follow where a fish ended up after it was caught.
