Beaufort Sea study seeks to prospect and protect complex Arctic ecosystem

The Arctic has become the target of some ironic attention lately. While part of the international community eyes the region as a climate change indicator, many other entities have set their gaze on the oil and gas reserves that could fuel such change. Now a collaboration between federal and private sector organizations, as well as U.S. and Canadian scientists, seeks to uncover the workings of the Arctic Beaufort Sea ecosystem so that its potential for human use is understood alongside the requirements for its protection. Being the federal agency responsible for offshore energy development, the Bureau of Ocean Energy Management is leading the Marine Arctic Ecosystem Study with help from the other nine members of the National Oceanographic Partnership Program.

New Rotorua Te Arawa Lakes data buoy tracks polymictic lake’s oxygen dynamics

A new data buoy launched this year in New Zealand’s Lake Rerewhakaaitu is providing scientists with insights into the polymictic lake’s oxygen dynamics and water column production. Polymictic lakes turn over many times per year. The next-generation profiler is overseen by the Rotorua Te Arawa Lakes Programme and uses an automated winch to raise and lower sensors on a regular basis. “The winch allows us to use a single package of water quality instruments to measure multiple depths through the water column,” said Chris McBride, technician at the University of Waikato who is helping the RTA Lakes Programme oversee the buoy.

Susquehanna River Basin Commission network monitors headwater streams amid Marcellus drilling

While hydraulic fracturing for natural gas in the Marcellus Shale in Pennsylvania and southern New York has drummed up controversy, a shared appreciation for clean water quality in the region hasn't been so divisive. When environmental scientists from the Susquehanna River Basin Commission sought permission from private landowners to install monitoring stations on headwater streams that run through landscapes where drilling has been intense, the response was receptive regardless of their stance on fracking. "They could be on one side or another," said Dawn Hintz, an environmental scientist with the commission. "Some people were for the drilling, some were against it. It didn't really seem to matter. They just wanted it monitored.
