Coastal Restoration in Rhode Island

Anyone who has spent a significant amount of time in nature can likely relate to feeling connected and defensive toward protecting the environment. Heather Kinney, a coastal restoration scientist with The Nature Conservancy in Rhode Island, knows this feeling well, having felt a deep connection to nature her entire life. “I have always had a deep love for nature and the environment, particularly being out on the water and being drawn to the ocean, as cliché as that sounds,” says Kinney. Being so close to nature her entire life led Kinney to pursue a career in conservation and restoration. “You want to protect what you love, and I think that once I fell in love with it- it was something that I wanted to be able to pursue professionally,” she explains.

Not So Quiet Polar Night: Arctic Creatures Found to be Active During Dark Part of the Year

Most people need little more than a comfortable pillow, a blanket, and a dark room to drift off into a multi-hour snooze. Many researchers assumed that once plunged into darkness for about half the year during the polar night, most polar creatures would do the same: fall asleep and take a big nap for as long as the darkness lasted. But Jon Cohen, associate professor of marine sciences, school of marine science and policy, in the College of Earth, Ocean, and the Environment at the University of Delaware, wondered if that was true. Despite the technical challenges of monitoring biota in very low light conditions, Cohen and his team were determined to find out if krill, copepods, and other creatures were dozing off in the dark or seeking out prey, light, and each other.

Orange Stream Dreams: Monitoring Acid Mine Drainage and Watershed Health

Not many young people pondering careers come up with the words “acid mine drainage.” But Jen Bowman, Director of Environmental Programs at the Voinovich School at Ohio University, could not help but be fascinated by what she saw during her days as an Ohio University student collecting field samples. “My interest in acid mine drainage, and how it affects watersheds, goes way back to my undergraduate days,” she explains. “We saw firsthand how streams could be impacted by drainage from abandoned mines. Sometimes streams had such severe problems they turned orange. It was hard not to be struck by that. I was drawn in to the many associated challenges, keeping watersheds clean, and improving stream health.
