Overview
The Pro-Oceanus Mini TDGP measures the total dissolved gas pressure in liquids. It provides accurate TDGP data and is designed for use in aquaculture, dam spillways, groundwater monitoring and industrial applications.

Maintenance
Unlike other total gas pressure probes, the Mini TDGP is not affected by increasing hydrostatic pressure. The sensor’s semi-permeable membrane is also biofilm resistant. With periodic membrane cleaning and calibration checks, the Mini TDGP requires minimal maintenance.

Applications
The rugged Pro-Oceanus Mini TDGP sensor is designed for use in water, oil, and contaminated mixtures. The probe combines an oil-resistant membrane with a compact pressure sensor that provides quality TDGP data. The Mini TDGP sensor can be used for long-term deployments with simple, stable and accurate results.

Collecting Data at the Top of the World: How Scientists Retrieve Glacial Ice Cores

A helicopter touches down in the small town of Sicuani, Peru, at an elevation of 11,644 feet. Earlier that day, a boxcar brought fuel, drills, food, and other equipment for a glacial expedition. The year is 1979, and glaciologist Lonnie Thompson is preparing to lead a team to the Quelccaya ice cap in hopes of becoming the first scientists to drill an ice core sample from this glacier. The only problem? The glacier is located at 19,000 feet in one of the most remote areas of the world. The helicopter takes off from the town, but the thin atmosphere at that elevation does not allow it to safely touch down on the ice– due to the aircraft’s weight, and it becomes unstable when the air is less dense.

Combining Academia and Lake Associations: Monitoring Lake Lillinonah

Lake Lillinonah may be Connecticut's second-largest lake, but it holds a great deal of meaning for locals and researchers in the surrounding towns. The lake is so significant to the surrounding community that it is one of many lakes in the United States with a dedicated lake association advocating for the resource. Jen Klug, Professor of Biology in the College of Arts and Sciences at Fairfield University , started her career at Fairfield as a natural progression in her background as a classical aquatic ecologist and found herself working closely with Lake Lillinonah's Friends of the Lake (FOTL) when they reached out to collaborate on an algae presentation for a public forum back in 2006.
