Travels in Geology: Glacial pools to sea caves: A tour of New Zealand's South Island

New Zealand has a reputation for extreme adventure — sky diving, jet boating, bungee jumping and even “zorbing,” which sends you rolling down a hill inside a transparent plastic ball. But beyond the adrenaline sports, you’ll find unique geologic features in landscapes ranging from volcanoes and alpine peaks to beaches and rainforests.

CryoScoop: Green Light to McMurdo

Polar scientists breathed a sigh of relief yesterday as the good news reached inboxes: Icebreaking capability was restored to McMurdo Station, preventing the deferment of some Antarctic field work this year.

Each year, an icebreaker heads to McMurdo Sound where it cuts and maintains a path to McMurdo Station, a large U.S. Antarctic research base and the stage for logistical operations, located on the southern tip of Ross Island. The ice-free channel allows for the passage of tankers and cargo ships bringing supplies and fuel to the remote establishment.

Thinking outside the rocks in the search for ancient earthquakes

The eyewitness accounts, written in columns from right to left, top to bottom, testify that there was no warning of the tsunami, no shaking to drive villagers to high ground before the wave hit, drowning rice paddies and swamping a castle moat. The entries, written by merchants, peasants and samurai, all clearly mark the time and date: just after midnight on Wednesday, Jan. 27, 1700.

A day without Glory

On a warm afternoon in early March, the Taurus XL rocket that was prepped for launch at Vandenberg Air Force Base in Southern California looked more like a giant chopstick standing on end than a potential game changer in the debate over climate change science. The barrel-shaped satellite that the rocket carried — named Glory — was designed to deliver critical information about small airborne particles called aerosols.

Mineral Resource of the Month: Gypsum

You may not realize it, but the walls of your office are probably made from a mineral: gypsum. Gypsum is an abundant, evaporite-derived sedimentary mineral with deposits located throughout the world. It is often associated with paleo-environmental lake and marine environments. In its pure form, gypsum consists of calcium sulfate dihydrate, although most crude gypsum naturally occurs in combination with anhydrite, clay, dolomite and/or limestone.
