The X2-CB is an all-in-one environmental data logger specifically designed for use with a NexSens CB-Series data buoy. It automatically recognizes sensors and sends data to the web via Wi-Fi, cellular, radio, or satellite telemetry. The X2-CB includes five sensor ports that are compatible with most environmental sensor protocols including SDI-12, RS-232, and RS-485. All connections are made with a simple waterproof thread-in connector, and the built-in sensor library automatically facilitates setup and configuration. Sensor data is recorded on common or independent schedules.
The X2-CB is powered from the CB-Series buoy’s solar rechargeable battery reserve. Advanced power management combined with ultra-low sleep and run currents extend battery life and reduce the need for larger buoy and solar charging systems. The X2-CB monitors itself while collecting environmental data. Internal temperature, humidity, voltages, and currents are constantly recorded. Failure alerts can be sent automatically to a predefined list of contacts.
The X2-CB integrates the sensor ports, solar panel connector, battery vent, and wireless antenna all on the data well lid for quick installation on CB-Series data buoys. Optional integrated Wi-Fi, cellular, radio, or satellite telemetry modules offer real-time remote communications via the WQData LIVE web datacenter. There, data is presented on a fully-featured and easy-to-use dashboard. Other features include automated reports, alarms, push notifications and much more.

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.
