AP PHOTOS: Antarctica's spectacular glaciers melting faster

CAPE LEGOUPIL, Antarctica (AP) From the ground of this extreme northern part of Antarctica, a spectacular white and blinding ice seemingly extends forever. What can't be seen is the battle raging below to reshape Earth.
Water is eating away at the Antarctic ice, melting it where it hits the oceans. As the ice sheets slowly thaw, water pours into the sea, 130 billion tons of ice (118 billion metric tons) per year for the past decade, according to NASA satellite calculations. That's enough ice melt to fill more than 1.3 million Olympic swimming pools. And the melting is accelerating.
In the worst case scenario, Antarctica's melt could push sea levels up 10 feet (3.3 meters) worldwide in a century or two, recurving heavily populated coastlines.
At its current rate, the rise from Antarctica would only lift the world's oceans a barely noticeable one-third of a millimeter a year.
But if all the West Antarctic ice sheet that's connected to water melts unstoppably, as several experts predict, there won't be time to prepare. Scientists estimate it will take from 200 to 1,000 years to melt enough ice to raise seas by 10 feet, maybe only 100 years in a worst-case scenario.
For a dozen days in January, in the middle of the chilly Antarctic summer, The Associated Press followed scientists from different fields searching for alien-like creatures, hints of pollution trapped in ancient ice, leftovers from the Big Bang, biological quirks that potentially could lead to better medical treatments, and perhaps most of all, signs of unstoppable melting.
A zodiac boat carried a team of international scientists to Chile's station Bernardo O'Higgins, and a group of penguins stood on a rock near the mission. Scientists collected samples on Deception Island, and elsewhere in Antarctica during the visit.
Here's a look at some of the images from the trip:
