To Protect and Preserve: Environmental Monitoring Central to Mission of Chesapeake Bay

In her 30th anniversary article about the Chesapeake Bay (Maryland) NERR, Jenn Raulin of the University of Maryland, Chesapeake Biological Laboratory, had this to say about the NERR: “CBNERR-MD is one of twenty-nine Research Reserves across the Country and along with just a handful of other Reserves is comprised of multiple sites." Former Deputy Secretary Frank Dawson who was acting manager of CBNERR-MD at the time of designation provides some insight, "The vision of the Reserve program in Maryland was to have multiple components that would reflect the diversity of the estuarine systems of the Chesapeake Bay, allow us to monitor change, research pressing issues, and provide opportunities for hands-on educational experiences.

Sensor Array Stretching Across the North Atlantic Reveals Drivers of Global Currents

Most of us are aware that the oceans of the world play a tremendously important role in both the regulation of the global climate and the uptake of atmospheric carbon. However, one might be forgiven for being less aware of the amazing complexity of the meridional overturning circulation (MOC) of the world's oceans. Scientists around the world are still learning about these drivers of our global climate system. The AMOC, that portion of the MOC in the Atlantic, is critical to average climate worldwide. Characterized by fluctuations from north to south and back again, warmer waters move northward on the globe, allowing deeper, colder waters to circulate toward more central areas.

BRUVS Capturing Deep-Reef Fish Communities

Until recently, it's been difficult for scientists to monitor, inventory, and study deep water fishes. Yet these species are critical to understanding threats posed by climate change, fishing pressure, and pollution, among other factors impacting marine life. Now, teams are using newer technologies to access and document fish abundance and diversity among deeper reef settings. Tiffany Sih , a PhD candidate from James Cook University, has used Baited Remote Underwater Video Stations (BRUVS) with lights to sample deeper habitats (54–260 m), in the Great Barrier Reef (GBR), Australia. Sih corresponded with EM about her recent work , the first study of its kind looking deeper than 100m, and what inspired her to take the deeper dive.
