Penobscot Indian Nation Safeguards Tribal Waterways

Tribal members of the Penobscot Indian Nation have long believed that the Penobscot River was the lifeblood of their people, providing food and transportation needed to support survival. Clearly, keeping water quality good in the river is of concern to natural resource managers with the tribe. But the Penobscot River is not the only waterway that flows through tribal lands. There is Dolby Pond, a prominent water body in the state of Maine monitored in recent years by a sensor-equipped floating platform, and many other streams and creeks that trickle through the nation’s territories. For these, natural resource managers make routine trips to monitor their health, relying on significant parameters like temperature, conductivity, dissolved oxygen and pH.

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.

CastAway Doubts about Conductivity, Depth and Temperature Monitoring

The Sontek CastAway-CTD is a castable device that measures conductivity, temperature and depth. The instrument has been used in the field for over a decade by oceanographers, limnologists, divers, fishers and educators. There have been few changes since the first iteration in 2010, showing that the instrument is durable and accurate without requiring new models.   The CastAway is the first conductivity, temperature and depth (CTD) instrument of its kind. While other CTDs are large and cumbersome to deploy, with cages and isolated sensors, the CastAway is a small, lightweight and easy-to-use instrument. Typical CTDs utilize pumps to ensure water flows over the sensors during deployment.
