Ice (Re)Cap: December 2016

From Antarctica to the Arctic; from polar caps, permafrost and glaciers to ocean-rafted sea ice; and from burly bears to cold-loving microbes, fascinating science is found in every nook and crevasse of Earth’s cryosphere, and new findings are announced often. Here are a few of the latest updates.

Benchmarks: December 6, 1916: Dinosaur fossils lost at sea in World War I

One hundred years ago this month, a Canadian cargo ship — the SS Mount Temple — departed the port of Montreal on the St. Lawrence River headed for France. On board were 3,000 tons of wheat, more than 700 horses bound for service in World War I, and an unknown number of 75-million-year-old dinosaur skeletons and bones destined for the British Museum of Natural History. But the ship, and the fossils, never made it.

Down to Earth With: Underwater cave explorer Jill Heinerth

Jill Heinerth has trekked farther into caves than any woman in history and logged more than 7,000 dives across every continent and up to roughly 140 meters underwater — recreational divers only reach depths up to 40 meters. She has dived inside icebergs in Antarctica, beneath the Sahara Desert, and in the turquoise waters of the Bahamas.

Coral Reef Roundup: December 2016

With multiple threats facing our coral reefs — from climate change to overfishing — and scientists continually studying the coral reefs beneath the waves, new findings are announced often. Here are a few of the latest updates.

Nutrient deficiency delayed life after mass extinction

After Earth’s most severe mass extinction, life took up to 9 million years to recover — millions of years longer than after other extinction events. New research published in Geology suggests that a collapse in the ocean’s productivity might have been the cause.

Ancient plankton communities stressed before mass extinction

Changes in our modern ecosystems, such as declines in biodiversity and invasive species, are similar to those that preceded the first of Earth’s mass extinctions about 443 million years ago, according to a new study. Researchers recently found that ancient plankton communities began to show environmental stress nearly 400,000 years before the extinction, as the planet cooled.

Pluto may still have liquid ocean

Last year, images from NASA’s New Horizons flyby of Pluto revealed geologic activity that suggested a liquid ocean may have once lurked beneath the dwarf planet’s icy crust. But whether it still exists in that state, or had frozen, remained a question. According to a new study published in Geophysical Research Letters, it may still be partially liquid.

Benchmarks: November 13, 1985: Nevado del Ruiz eruption triggers deadly lahars

On Nov. 13, 1985, at a little after 9 p.m. local time, Nevado del Ruiz, a volcano about 130 kilometers from Colombia’s capital city of Bogotá, erupted, spewing a violent mix of hot ash and lava into the atmosphere. Less than three hours later, the earth rumbled as mudflows towering nearly 30 meters high swept through the countryside, several villages and eventually the town of Armero, where it killed 70 percent of the town’s residents. All-told, these mudflows, called lahars, killed more than 23,000 people.

Toad behavior linked to climate change

Fowler’s toads — listed as endangered in Canada — hibernate for eight months to escape harsh winter conditions. They bury themselves up to a meter deep in the sand dunes along the shore of Lake Erie in Long Point, Ontario, which is the northern extent of their range. In May, they emerge at the surface to breed, in response to warmer air temperature and the lunar cycle. But scientists have now found that the toads are emerging earlier in the spring, according to a new study in Global Change Biology.

Down to Earth With: Volcanologist Kayla Iacovino

When Kayla Iacovino enrolled as a freshman at Arizona State University in 2005, she thought she might become an astronaut. But, after a field trip to outcrops in northern Arizona during her first semester, she became hooked on geology.
