Reading the ridges: Are climate and the seafloor connected?

New research suggests that midocean ridge volcanoes respond to variations in sea level, potentially leaving topographic records of past glaciations in the form of abyssal hills. But could those volcanoes also influence the climate cycles that drive sea-level changes?

King Oraefajokull

The Öraefajökull Volcano boasts Iceland’s highest peak — 2,109 meters above sea level — and has the reputation of being Iceland’s largest and most violent volcano. Major eruptions in 1362 and 1727 were among the most explosive in the island’s history, and both were accompanied by catastrophic glacial floods. After the 1362 event, the Icelandic word öraefi, originally meaning “area without a harbor,” was rechristened to mean “wasteland.”

Where fire freezes: All eyes, ears and instruments on Iceland's volatile volcanoes

With examples of every type of volcano on Earth — each with its own eruptive pattern — Iceland presents a special challenge to volcanologists, but also serves as an ideal natural laboratory for studying how volcanic processes evolve.

Eerily quiet Katla

Katla Volcano is located near the southern tip of Iceland, under the Mýrdals­jökull Ice Cap. Ashfall deposits found as far away as Norway and Denmark indicate that Katla erupted at least 20 times between A.D. 930 and the last eruption in 1918. Its present dormancy is the longest-known quiet period in the volcano’s history.

Hekla the heckler

Hekla is one of Iceland’s most active volcanoes, erupting more than 25 times since its first recorded eruption in 1104. The most recent eruptions in 1970, 1980, 1981, 1991 and 2000 have allowed geoscientists to create a detailed eruption profile for the volcano.

Travels in Geology: Gotland getaway: Sweden's 'tropical' escape in the Baltic

Gotland, a Silurian-aged coral-reef island with white sand beaches, lies not in the tropics but in the Baltic Sea off the southeastern coast of Sweden just a short trip from Stockholm. In addition to the carbonate geology, visitors can view medieval churches and thatched-roof Viking farms, and experience the moody, atmospheric weather featured in the films of director Ingmar Bergman.

Getting there and getting around Jordan

Jordan has two international airports: Amman and Aqaba. Amman’s Queen Alia International Airport is the main gateway, offering service to most major Middle Eastern and European cities and regular nonstop flights to New York, Chicago and Montreal. The airport is located 35 kilometers south of Amman; reach the city via express bus service or taxi. Taxis also serve Madaba, which is much smaller and closer to the airport. Madaba hotels will arrange airport pickup and King’s Highway transportation for you. The most convenient and flexible exploration option is with your own vehicle. Several rental agencies operate in Madaba, with more selection at the airport. Our vehicle was delivered to our Madaba hotel, allowing us to avoid city driving in Amman. Signs are generally in both Arabic and English.
