Research expedition braves world's worst weather

22.06.2006
The Mount McKinley Project, funded by the International Arctic Research Center (IARC) at the University of Alaska Fairbanks, has endured its share of horrific blizzards, heart-stopping ridge ascents and the unrelenting burn of a blazing sun during the past four seasons of weather station installation. The expedition climbs to 18,700 feet, just below the 20,320 foot summit of Mount McKinley, to perform upgrades to the weather station perched upon the tallest peak in North America. It's one of the three highest altitude meteorological stations in the world.

In recent years the equipment contained two components, a weather station to record meteorological data and a telemetric component to broadcast data to a base station in the town of Cantwell. The weather station failed at some point during the previous four seasons, causing researchers to modify the design. Last year, although the telemetry worked well, the data contained obvious inaccuracies after September.

With continued support from the National Park Service, this year the expedition returns for a fifth acquaintance with McKinley. The expedition commenced June 7, and will last until the end of the month.

Two anemometers, or wind measuring devices, are included in this year's weather station design. One is a standard instrument with three rotating cups and the other is an ultrasonic device, which measures wind speed by monitoring a signal sent between two sensors. As they work side by side, these anemometers will reveal information about sensor accuracy.

The project started about a decade before it was funded by IARC. Yoshitomi Okura, who is affiliated with the Japanese Alpine Club, started the project in the early 1990s after three of his friends were blown off the mountain and killed. One of the most famous Japanese climbers, Naomi Vemura, also diappeared at about the same location.

Tohru Saito, a liaison with IARC, who will be ascending McKinley for the fifth consecutive year, stated, "Okura is passionate about collecting data from McKinley, both to understand the nature of the fierce winds and to prove that climbers like his friends were not inexperienced, they just faced incomprehensible conditions."

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
