The Monterey Bay Aquarium Research Institutes Wireless Plan to Connect to MARS
Engineers and scientists that specialize in aquatic measuring practices always meet extra costs on the path to deployment. Maybe it is the corrosive nature of the saltwater, or the unbearable pressure tools must be equipped to handle while lying on the ocean floor. For anyone interested in hooking up with the MARS (Monterey Accelerated Research System) Observatory , which rests dozens of miles off the California coastline, the costs extend further. They get so high that only well-funded universities and governmental agencies can afford to connect with the underwater power and data hub. Hoping to lower that cost, engineers with the Monterey Bay Aquarium Research Institute ( MBARI ) constructed a wireless device called Deep-Sea Connect.

With Cameras and Artificial Intelligence, Fishing Vessels are Becoming Smarter
During an electronic monitoring conference in February, fisheries managers and fishermen watched a squiggly purple line meander across the screen. It was mapping the journey a tuna fish was taking, from being caught and landing across the deck of a fishing vessel. Leigh Habegger, executive director for Seafood Harvesters of America , a national commercial fishing group, said everyone in the crowd had their eyes glued to the screen. “It was fascinating, it was really cool,” she added. The graphic was the manifestation of a machine-learning tool that was trained to follow where a fish ended up after it was caught.

Mercury and Lake Levels Rise and Fall Together around Great Lakes
Sometimes the scientific process makes for a great story. Sometimes, like when discovering the relationship between lake levels and mercury levels in fish, it brings a few stories into one. “It’s really two or three stories wrapped into one, and the wrapping was a bit of a surprise to us,” said Carl Watras, a research scientist at the Wisconsin Department of Natural Resources and the Center for Limnology at the University of Wisconsin—Madison. In January, Watras and a team of researchers published findings in Environmental Science & Technology Letters that related water levels in lakes to mercury levels in walleye and loons. From the Pacific Ocean to Mercury Levels in Wisconsin One of those stories is one of cross-continental influence.
