The Discrete Interval Sampler can also be used to profile open bodies of water, boreholes, and to collect samples from distinct levels or points of inflow. The Discrete Interval Sampler is a passive sampler that is pressurized when lowered and upon retrieval, to prevent water mixing at different levels. Designed to give zero purge samples.

Solinst groundwater samplers: Versatile options for a variety of applications
Groundwater sampling can be a challenging task that requires different tools for different applications. Solinst groundwater samplers offer the capability to obtain commonly needed representative samples of groundwater using different approaches of water withdrawal. Solinst’s 425 Discrete Interval Sampler uses passive sampling to grab water from a specific depth. The 407 Bladder Pump enables continuous airtight low flow sampling. The 408 Double Valve Pump can continuously sample at variable rates. “One sampler isn’t necessarily going to be for every site,” said Randy Blackburn, Solinst product manager. Each has different means of fluid sampling. The 425 sampler relies on a manual air pump that pressurizes the sampler based on the water depth.

New Technologies Reducing Uncertainty in Estimation of River Flow
Some of the most interesting data in the world of river and stream monitoring come at times when it's practically impossible to capture—during extreme weather events, for example. Timing alone makes capturing unusual events a challenge, and these kinds of issues have prompted researchers to use classic monitoring data along with new technologies to develop and improve hydraulic modeling for estimating river flows. Steven Lyon , a Conservation Scientist with The Nature Conservancy, Professor at Stockholm University and Associate Professor at The Ohio State University, spoke with EM about the research .

Cornell University Biological Field Station at Shackelton Point: Monitoring New York’s Largest Interior Lake for Sixty Years
Lars Rudstam, Professor of Aquatic Science at Cornell and Director of the Cornell University Biological Field Station at Shackelton Point, says that he has long held an interest in lakes in general, so naturally the Great Lakes, the largest freshwater lake system in the world, have held a fascination for him for many years. He also works on Oneida Lake, the largest lake wholly inside New York. Oneida Lake waters, traveling from the Lake to the Oneida River, then to the Oswego River, ultimately flow into Lake Ontario. “In addition to lakes in general and the Great Lakes, I have been especially interested in the impressive data series that has been collected for Oneida Lake,” Rudstam notes.
