Benchmarks: March 29, 1912: Scott's South Pole Journey Ends in Death

The epic tale of the race between Norway and Britain to be the first to reach the South Pole — and its tragic conclusion with the deaths of British team members in February and March 1912 — is well known. But the details of what happened on the ice, of what went wrong for the British expedition, have continued to be discussed and debated since the bodies of Capt. Robert Falcon Scott and his four crewmates were discovered the following summer. Several recent studies on the Antarctic climate and on the questionable behavior of Scott’s second-in-command are casting new light on the outcome of the expedition.

Benchmarks: January 25, 1968: The last firefall: A Yosemite tradition flames out

Fifty years ago this month, on Jan. 25, 1968, a massive bonfire built of red fir bark atop Glacier Point in Yosemite National Park was burned down to embers and, promptly at 9 p.m., and for the last time, pushed over the cliff edge to create a flaming cascade for the viewing enjoyment of tourists gathered below. The spectacle, called “firefall,” had been a beloved Yosemite tradition for nearly a century.

Benchmarks: May 23, 1967: Space weather forecasters avert war

In spring 1967, international political tensions were high. The United States and the Soviet Union were engaged in the space race, as well as a nuclear arms race. The Cuban Missile Crisis, less than five years earlier, was still fresh in people’s minds. The war in Vietnam was escalating, as was the U.S. antiwar movement at home. And in the Middle East, Israel and its neighbors were on the precipice of the Six Day War.

Bringing geoscience to bear on the problem of abandoned mines

With 3 million gallons of acidic, heavy-metal-laden water behind an earthen plug at high elevation, Colorado’s Gold King Mine was, literally, a situation just waiting to go downhill. The blowout last August shone a spotlight on the larger problem of abandoned mine lands. What role do geoscientists play in solving it?

Down to Earth With: Solar physicist Thomas Berger

Growing up in California during the Space Race, Thomas Berger was fascinated with aeronautics and aviation, so when he arrived at the University of California at Berkeley, physics seemed like the natural choice. After graduating with a degree in engineering physics, Berger took a job with Lockheed Aircraft in Burbank. But he soon decided it was not for him and returned to graduate school at Stanford, where he discovered a new passion: solar physics.

Benchmarks: April 22, 1995: GLOBE is launched

Studying the global environment requires collecting numerous detailed observations. And although it may seem today like we’re awash in such data, relevant observations — collected at the right time and place — are often unavailable. For example, scientists studying precipitation must rely on just a handful of sampling stations: All of the world’s raingages gathered together would only cover an area the size of two basketball courts.

Benchmarks: March 17, 1944: The most recent eruption of Mount Vesuvius

Four-and-a-half years into World War II, the residents of San Sebastiano, Italy — a Neapolitan village on the western slopes of Mount Vesuvius — had already endured much misery: dictatorial rule, invasion, occupation and bombings. In mid-March 1944, they faced yet another catastrophe, this one a natural disaster that would destroy their town.

Oceanographers solve mysterious beach explosion

Late on the morning of Saturday, July 11, 2015, Kathleen Danise, a 60-year-old nurse and grandmother from Waterbury, Conn., was enjoying a sunny day at Salty Brine State Beach on the shores of Block Island Sound in Narragansett, R.I., when an explosion knocked her from her beach chair. She landed a few meters away near a rock jetty, unconscious and suffering a concussion, two fractured ribs and bruising for which she was hospitalized overnight.

The question of mantle plumes

The mantle plume hypothesis is the most widely held explanation for volcanism far from plate boundaries, like Hawaii and Yellowstone. But some researchers question whether mantle plumes even exist.
