Flow Control in Antarctica

With just days left before Stanford researcher David Mucciarone would leave on his annual pilgrimage to Antarctica, the mass flow controller in his carbon analyzer failed.

His instrumentation supplier recommended that he make the transition to Sierra. On a wing and a prayer, he purchased a Sierra Smart-Trak® Model 100 digital mass flow controller just prior to boarding ship. He installed it on the trip down to Antarctica, and it worked, perfectly. But fierce trials lay ahead as the icebreaker he was travelling on plunged through miles of thick ice before delivering him to one of the most severe environments on Planet Earth.

Despite the challenges, the Smart-Trak® has never faltered. “We’re very happy and that’s the bottom line,” says Mucciarone.

No greater challenge faces our planet right now than determining conclusively how we are impacting the environment and what can be done to arrest and reverse global warming. To deepen our understanding, Stanford researcher David Mucciarone spends two months in the Antarctic every year measuring the breakdown of inorganic carbon in both sea and ice to learn how much carbon dioxide the ocean can effectively digest. Based on his success with the carbon analyzer, he plans to employ additional analyzers on ocean reef and other ecosystems around the world—each containing a Sierra Smart-Trak® mass flow controller.
