The CB-75 Data Buoy is a compact, affordable, and easy to deploy platform for both water and atmospheric observations. At 21” (53.34cm) hull diameter and 40 lb. (18.14kg) weight, it’s ideally suited for tethered moorings. The buoy is designed to integrate the X3-SUB Submersible Data Logger, which includes external sensor ports to support weather stations, thermistor strings, multi-parameter sondes, Doppler current profilers, GPS, and other monitoring instruments.
Constructed of an inner core of cross-linked polyethylene foam with a tough polyurea skin, the CB-75 is designed for years of service. Select from a solar top with rechargeable battery pack for long-term deployments or a blank top with alkaline battery pack for short-term or seasonal applications. All electronics are housed in a quick-removable X3-SUB data logger package with wet-mateable connectors. A removeable instrument cage serves as counter-ballast and supports instrument mounting, while three 1.5” (3.81cm) pass-through holes facilitate cable routing of underwater sensors.
Available with integrated 4G LTE or Iridium satellite communications, the CB-75 Data Buoy sends data in real-time to the cloud-based WQData LIVE datacenter. In the Basic tier, this free service allows users to securely access and analyze data, as well as share data through an auto-report. Subscription-based tiers of WQData LIVE are also available for generating custom alarms, exporting data through an API or custom NDBC/GLOS formats, and providing a publicly-accessible version of the project website.

Protecting Chicago's Lakefront: Freshwater Beach Monitoring
Thousands of people flock to the Great Lakes every year to enjoy the freshwater beaches along the coast. As an urban hub with over 2.5 million residents, beachfronts in Chicago have regular visitors as well as tourists that recreate in the bordering Lake Michigan. According to the Chicago Park District, it is estimated that more than 100,000 residents and visitors per day use Chicago’s Lakefront trail during summer weekends. Proximity to the Lake is not only a recreational activity for Chicagoans, but also a part of the city’s history due to its role in domestic and international shipping routes. In addition, the Lake serves as a drinking water source and as an essential climate regulator in the region that acts as a natural air conditioning affect.

Sustainable Fishing in Alaska: Protecting the Salmon Capital of the World through Research
In the far north, the Alaska Peninsula stretches away from the Last Frontier into the Pacific Ocean. A narrow strip of land dotted with freshwater lakes and intruded upon by ocean inlets–this unique region is intimately connected with the surrounding water. Nestled halfway down the peninsula's southern coast are the small villages of Chignik. The area has historically been home to the Aleut people and has been heavily reliant on fishing for centuries. Home to commercial and subsistence fishing today, Chignik continues to rely upon the salmon returns to the surrounding villages, which are supported by scientists working tirelessly to understand and steward these fish populations.

NexSens X3 Data Logger Review
Extreme environments meet extreme design with the NexSens X3 Data Logger . The new logger offers the latest in real-time monitoring technology with wireless communication, a large plug-and-play sensor library and ultra-low power consumption, all in a waterproof marine-grade housing. The X3 is built to handle harsh weather, floods, high winds and rough seas, and it stands alone; no additional protective housing needed. With an operating temperature that ranges from -40°C to 70°C, the logger can withstand arctic environments and extreme heat. A conformal coating on the internal circuit board isolates it from moisture and humidity.
