Ship life

Perhaps the most common question I’ve gotten after returning from my trip is, “Did you get sea sick?” The answer is yes, but I wasn’t miserable. And in truth, very few individuals missed out on any of the shore excursions because they didn’t feel well.

Getting there and getting around in Antarctica

Traveling to Antarctica pretty much requires being part of an organized tour, something tens of thousands of people do each year. We went on a trip arranged by the Geological Society of America and Cheesemans’ Ecology Safaris. If you aren’t lucky enough to take a scientific tour, there are plenty of more traditional tours that will get you there. Most depart from Argentina, but some go through the Falkland Islands as well as Australia and New Zealand.

Where on Earth? - January 2014

Clues for January 2014:
1. The island seen in the distance in this 1963 photo, one of many in the archipelago nation of which it is a part, is an andesitic to dacitic stratovolcano. In historical times, the volcano is known to have erupted in about 1568, 1650, and most recently between about 1830 and 1850.

Energy 360: Moving energy - No easy feat, but a vital conversation

Trucks, trains, planes and boats move food, clothing, cars, wood, steel, medical products, smartphones, bicycles, organic milk, free-range chickens—basically all consumer goods. And energy is no exception. Coal is mined and then carried to where it is burned. Oil and natural gas are moved from where they are produced to where they can be refined into transportation fuels and myriad other products, and then moved again. Uranium is mined and transported to create fuel rods for nuclear power plants or nuclear-powered ships.

Hazards abroad: Sent home

On May 19, 2012, seismologist Roger Bilham of the University of Colorado at Boulder landed at the airport in Delhi, India, on his way to Bhutan. He debarked from the plane and was met by Indian customs officials, who declared he was on the “blacklist” and not allowed entry to India, despite having a valid visa. Two hours later, he was on a plane heading back to the U.S.

Be prepared: Navigating the risks of hazards research

Just over a year ago, in a cavernous room of the Moscone Convention Center in San Francisco, Calif., hundreds of geophysicists, seismologists, volcanologists and climate scientists, as well as a few journalists and a lawyer or two, sat transfixed as a panel discussed the manslaughter conviction of six scientists and a public official in Italy a few months earlier.

Hominin skull discovery fuels debate about early human evolution

Hailed as a find for the ages, a rare skull of a 1.8-million-year-old human relative could provide answers to longstanding questions about the lineage of our species. It also fuels debate over what differentiates one hominin species from another, and could mean that Homo habilis, Homo rudolfensis and other early bipedal hominins may all be members of Homo erectus, rather than distinct species.

Environmental changes contributed to Mediterranean cultural crisis

About 3,200 years ago, urban cultures thrived in the Eastern Mediterranean until invasions in coastal and inland areas, compounded by agricultural decline, created a regional crisis.

Ancient volcanic island arc blocked Antarctic current formation

There has long been a debate in the geological community over what caused the formation of the Antarctic ice sheet during the Eocene-Oligocene period about 30 million years ago. One of the widely accepted hypotheses is that the glaciation was triggered by the commencement of the Antarctic Circumpolar Current (ACC), an ocean current that circles Antarctica insulating the continent from the warm waters to the north, allowing the ice sheet to remain relatively stable.
