Choosing The Right Thermo Portable For Your Project

With so many options in Thermo Scientific’s Orion Star A line, it can be difficult to narrow down which meter will best fulfill a project’s needs. One easy way to rule out some meters is by considering application type. For projects that rely largely on collecting samples in the field, a portable meter is clearly the way to go. But there’s still a handful of meters to choose from. To simplify making the right choice, we spoke with Ricki Hartwell, the global product manager for Thermo Scientific’s Orion Laboratory and Field Instruments. She recently shared her tips on choosing the right Thermo benchtop . Let’s take a look at her recommendations for selecting the right portable meter.

Mining Waste Cleanup Reveals Interesting Lake Dynamics

For the past decade or so, Dr. Bernard Laval , a civil engineer with the University of Northern BC in Canada, has been researching Quesnel Lake , a large, deep lake with unusual water dynamics. This allowed him an unusually high level of insight into much of what makes the lake tick—and when Mount Polley Mine (MPM) experienced a breach in 2014, causing materials to be deposited into Quesnel Lake, he already had a sense of what the lake's waters looked like. “Our work was inspired by a desire to improve holistic understanding of lake function to help with fisheries management by BC Ministry of Environment (BC MOE) and Fisheries and Ocean Canada (DFO),” explains Dr. Laval.

Narragansett Nature: Remote NERR is a leader in salt marsh stressor studies, crab studies and contributions to Rhode Island environmental policies

Unique among the 29 National Estuarine Research Reserves (NERRS), Narragansett Bay National Estuarine Research Reserve (NBNERR ) is made up of four islands: Prudence, Patience, Hope and Dyer. Protecting about 4,400 acres of land and water, NBNERR is a great place to see a variety of coastal habitats. There are upland maritime forests, coastal pine barrens, sandy beaches, cobble shorelines, salt marshes and open grasslands. NBNERR also has excellent hiking, fishing, clamming and bird watching. “If you want to see us, though, you’ll need to hop on a ferry,” says Bob Stankelis , NBNERR Reserve Manager. “Or you’ll have to take a boat. We’re not that easy to get to. But to be honest, that’s one of the big things residents here like about it: its remoteness.
