Overview
The Pro-Oceanus Mini CH4 instrument uses infrared detection to measure the partial pressure of CH4 gas dissolved in liquids. Conversion to dissolved methane concentration is simple with known temperature and salinity values.
Mechanics
Mini CH4 submersible instruments are compact, lightweight, plug-and-play sensors designed to measure pCH4 for a range of applications. The instrument also measures total dissolved gas pressure (TDGP), a useful parameter for many applications and data correction.
Applications
With resistance to most corrosive liquids, the Mini CH4 can provide reliable dissolved methane data for many applications. Flow-through and inline adapters are also available for simple industrial solutions.

Monitoring and Facilitating Habitat Restoration Efforts in the Great Lakes
While human infrastructure, urbanization, and industrialization have advanced human societies, the natural environment has suffered due to constructed impediments and deteriorating architecture. In order to combat this degradation, habitat restoration programs across the US work to remove impairments and improve damaged waterways.

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.
