Getting there and getting around England

From North America, the cheapest and most convenient access to the Jurassic Coast is via one of London’s major airports. Nonstop service to Heathrow (LHR) and Gatwick (LGW) airports is available from many major U.S. cities.From London, the easiest way to get to (and around) the Jurassic Coast is by renting a vehicle, assuming you’re comfortable driving on the left side of the road. Because Gatwick is located on London’s southern outskirts, it offers the best escape to England’s southern coast from the hustle and bustle of the city.

Travels in Geology: Mesozoic masterpiece: England's Jurassic Coast

England's southwestern shore is renowned for the nearly continuous 185-million-year record of Earth's history exposed in its sensational seacliffs, which record one of the world's best stratigraphic sequences from the Mesozoic Era.

Benchmarks: June 15, 1991: Mount Pinatubo erupts

Twenty-seven years ago this month, the calm in central Luzon, the largest and most populous island in the Philippines, turned to chaos. On June 15, 1991, Mount Pinatubo disgorged 5 cubic kilometers of material over a few hours, and ash clouds soared 35 kilometers into the atmosphere. The substantial eruption — the second largest of the 20th century — burned itself into memories and history books.

Mineral Resource of the Month: Chromium

Although chromium is a metal, it does not occur naturally in metallic form. Chromium can be found in many minerals, but the only economically significant chromium-bearing mineral is chromite. Chromite has been mined from four different deposit types: stratiform chromite, podiform chromite, placer chromite, and laterite deposits. Most of the world’s resources, however, are located in stratiform chromite deposits, such as the Bushveld Complex in South Africa. The economic potential of chromite resources depends on the thickness and continuity of the deposit and on the grade of the ore. Many of the major stratiform chromite deposits also contain economic levels of platinum, palladium, rhodium, osmium, iridium and ruthenium.

Skate eggs found on hydrothermal vents

In July 2016, a team of scientists came upon a surprise 1,660 meters beneath the ocean’s surface near the Galápagos Islands: a clutch of yellow eggs, laid by a Pacific white skate, a cousin of rays and sharks. It was not the eggs themselves that surprised the team, but where they were found: near a volcanic hydrothermal vent. The large number of eggs at the site led the team to suggest that the skate was likely using the vent’s heat to incubate the eggs.

TRAPPIST-1 system hosts seven "Earth-like" planets

In 2017, astronomers discovered seven planets orbiting a star dubbed TRAP­PIST-1, a faint red dwarf 40 light-years from Earth and only 9 percent as bright as our sun. The Earth-like qualities of these planets made headlines: they are of similar sizes to our planet, and their orbits fall within TRAPPIST-1’s habitable zone — two characteristics that scientists think are important for life to exist on a planet. Researchers now report that the TRAPPIST-1 planets have even more traits in common with Earth: they are likely rocky, and they may have surface water that exists as liquid, ice and vapor.

Are diatoms triggering submarine landslides?

Far beneath the ocean’s surface, puzzling deposits from huge submarine landslides can be found amid expanses of nearly flat ocean floor. Without steep terrain, what causes these megaslides? In a new study, scientists who delved into deep-sea drilling records report a potential trigger for one such slide off the coast of northwest Africa: diatom ooze.
