Mineral Resource of the Month: Bromine

Bromine, a naturally occurring element, is comparatively rare in Earth’s crust, but is found as a dissolved species in seawater, saltwater lakes and underground brines associated with petroleum deposits. Seawater contains about 65 parts per million of bromine — or an estimated 100 trillion tons, whereas the highly salty Dead Sea is estimated to contain 1 billion tons of bromine. Bromine is also recovered from seawater as a co-product during evaporation to produce salt.

Storms brewing over volcanoes

Two hundred years ago, a sea captain was sailing in the Azores, a Portuguese archipelago in the middle of the Atlantic Ocean, when he observed “an immense body of smoke rising from the sea.” As he watched, the smoke, from a volcanic vent offshore of the island of St. Michael’s, began to rotate on the water “like a horizontal wheel,” the captain wrote in his 1811 account of the event. The rotating smoke and ash grew into a dark column and ascended high into the sky, spawning waterspouts and flashes of lightning.

Oil barrel politics

As a new president and Congress entered office in January, current events continue to keep energy in the forefront of national concern. Volatile prices, resource depletion, climate change and national security impacts of energy trade have become a part of daily news and policy discussion. Americans will be watching the new policymakers to see how they respond to energy concerns. How they treat energy research and development — particularly the amount of funds dedicated to R&D, and the portion of that R&D that is allocated through earmarks — will be telling.

Coal-to-liquids: Can fuel made from coal replace gasoline?

Amid all the attention to the converging of three energy-related crises — climate change, resource depletion and international extremism funded by the energy trade — a surprising energy choice keeps rearing its head: coal. That especially includes liquid fuels made from coal, which can be a substitute for gasoline, jet fuel and just about any other transportation fuel on which we currently rely.

Earthquake prediction: Gone and back again

The 1990s and early 2000s were hard times for earthquake prediction research. “For 10 years, there was limited funding in the U.S.,” says Dimitar Ouzounov, a research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md., and professor at Chapman University in Orange, Calif. That changed in 2004, Ouzounov says, after a magnitude-9-plus quake struck off the coast of Sumatra and set off a tsunami, killing more than 225,000 people in 11 countries.

Jupiter breaks out in spots

Like any aging planet, Jupiter’s face has undergone a few changes over time. And even as the gas giant’s most famous feature — the colossal storm known as the Great Red Spot — appears to be shrinking, other spots have appeared.

Iron fertilization foiled by "shrimp"

The argument over whether ocean iron fertilization is a good way to sequester carbon dioxide may be coming to an end. Last month, a group of researchers seeded 300 square kilometers of the southwestern Atlantic Ocean with six metric tons of dissolved iron. Just as researchers hoped, algae bloomed, doubling in biomass within the first two weeks of the fertilization. But then, an unexpected guest showed up: tiny shrimp-like crustaceans that dined on the algae.

Where on Earth? - April 2009

Clues for April 2009:
1. In 2008, this mine’s geological province contained one of the richest stores of copper in the world outside of Chile.
2. The mine was the site of a massive strike in 1983. The strike became so heated that the National Guard was called in for added security under the mission name “Operation Copper Nugget.”
3. The mine’s neighboring town of the same name is the birthplace of an impressionist painter who studied under Diego Rivera.
Name this mine and its location.
