Mangroves sprouted in Arctic during Eocene

Mangrove trees, which today thrive in tropical and subtropical climates in the low and midlatitudes, grew in the high Russian Arctic about 56 million years ago, scientists reported in Geology. It’s the northernmost occurrence of mangrove trees ever documented.

Benchmarks: July 15-24, 1975: Apollo-Soyuz mission launches space collaboration

The space race between the United States and the Soviet Union spurred innovations and historic firsts for humankind from Sputnik to the moon landing. However, much of the drive to break through those technological barriers and explore the vast, starry landscape of space was rooted in a desire to display military dominance in space amid the competition and animosity of the Cold War.

A front-row seat at a fire-and-ice show

Many of the world’s volcanoes are high enough and cold enough to sport seasonal snow, and some even boast year-round glaciers. But what happens when those volcanoes erupt and molten lava hits snow and ice? Observing such extreme interactions of hot and cold is often dangerous in the field, but a slow-moving basaltic eruption in Russia in 2012 provided the right conditions to give scientists a close-up view on one fire-meets-ice display.

Mineral in Chelyabinsk meteorite reveals past collision

A new analysis of fragments of the Chelyabinsk meteorite — which burst over Chelyabinsk, Russia, in February 2013 — reveals that its parent asteroid collided with another asteroid nearly 300 million years before it struck Earth.

Russian earthquake ruptures superfast and deep

A “superfast” magnitude-6.7 earthquake was detected off the coast of Kamchatka, Russia, in May. The earthquake, called a “supershear” quake, is one of a handful of superfast earthquakes noted by researchers over the years, but this is the first identified at such great depth.

The impact at El'gygytgyn crater

Moment of impact: As the asteroid hits the ground with a velocity of several tens of kilometers per second, a shock wave is generated that penetrates radially into the ground and compresses the rocks.

Early results

Although our final results won’t begin to be published until early next year, our team met in May to review all the data we had collected so far.

We had drilled several types of cores. Our initial pilot cores, taken in 1998 and 2003, provided proof of concept, demonstrating the importance of these cores as a climate record, as they contain climate data that extend back in time 300,000 years — roughly three times longer back in time than the oldest portions of the Greenland ice core records.

The thrill to drill in the chill

Nearly 3.6 million years ago, a large asteroid slammed into Earth in what is today northeastern Russia. Within minutes, the impact formed an 18-kilometer-wide hole in the ground that then filled with water.

Travels in Geology: Exploring Lake Baikal, the Sacred Sea

Deepest. Oldest. Most biologically diverse. Siberia’s superlative-laden Lake Baikal is one of the planet’s great geological treasures. Located 4,200 kilometers east of Moscow and 2,100 kilometers west of Vladivostok, the lake known locally as the Sacred Sea is like no other.

How China, Russia and High Oil Prices Influence Global Dynamics

The world is changing. Gone are the days of Middle Eastern sheikhs controlling the world’s oil and our purse strings. Russia and China are changing the rules of the game.
