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.

Gettysburg rocks tell battlefield tales

Since the late 19th century, Civil War battlefield landscapes have changed. Some have been plowed under and developed, while elsewhere, woods have been cut down or become overgrown. But the rocks that dotted those battlefields from Gettysburg to Mississippi largely still stand. Historians are now using the steadfast boulders and ridges seen in the backgrounds of 154-year-old battlefield photographs to learn more about the skirmishes that took place at certain sites.

Isotopes reveal sources of centuries-old alabaster artifacts

When geologists think of alabaster, they likely envision blocks of gypsum, its main mineral constituent; when art historians hear the word, statues crafted from the soft rock may come to mind. A new study focused on the sources of centuries-old alabaster artworks has geologists thinking about art history, and art historians pondering geochemistry. In the study, published in Proceedings of the National Academy of Sciences, researchers used isotope fingerprinting along with historical records to tie medieval and Renaissance alabaster sculptures to the quarries from which their materials were excavated.

Dividing line: The past, present and future of the 100th Meridian

In 1878, John Wesley Powell first advanced the idea that the climatic boundary between the United States’ humid East and arid West lay along the 100th meridian, which
runs from pole to pole and, today, cuts through six U.S. states. But what does it really mean, and what is its future?

Nautical charts reveal coral decline around Florida Keys

Coral reef cover is known to have decreased over the past few decades, but longer term estimates of coral cover have been difficult to reconstruct. In a new study, researchers used high-resolution historical nautical maps from the 18th century to determine changes to reefs in the Florida Keys.

Benchmarks: September 23, 1806: Lewis and Clark's Corps of Discovery returns from the West

It’s been called the greatest camping trip of all time. Statues, counties, waterways, mountains, military vessels, and even two colleges bear the names of the journey’s leaders. Their journals are among our greatest national treasures, and their adventures have inspired generations of explorers. Two hundred and eleven years ago this month, Captains Meriwether Lewis and William Clark and their 31-man Corps of Discovery returned to St. Louis, the frontier town where they had started their journey 28 months and nearly 13,000 kilometers of wilderness earlier on May 14, 1804.
