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.

Sewage an Unseen and Ignored Threat to Coral Reefs and Human Health

It’s an open, dirty secret that the ocean is used as the ultimate sewage solution. Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up. “This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.
