In this collection of compelling images from around the web, sea monkeys make waves, fall colors are seen from space and a deadly volcanic eruption covers a temple in ash. Check out these and other amazing aerial and satellite images from around the world. Above, a National Weather Service satellite image from Sept. 30 shows the temperature of Earth's surface as a cold front moving across the plains brought severe thunderstorms to areas in South Dakota and Nebraska.Earth Shots: Must-See Planet Pics (Sept. 21)
This aerial picture taken on Sept. 28, 2014 shows rescue workers and Self Defense Force soldiers searching for missing climbers and survivors among ash-covered cottages and a Shinto shrine (top) on the summit of Mount Ontake, one day after the volcano erupted in central Japan. Dozens of hikers were killed and hundreds were trapped at the popular tourist destination.PHOTOS: Hiker Captures Japanese Volcano Eruption
An estimated 35,000 walruses gathered last week on an island near Point Lay, Alaska. The walruses, which reside in the Chukchi Sea, came ashore to rest, which they will do between dives for food. Walruses typically use sheets of floating ice as rest areas between swims, but such ice platforms melted away in mid-September.VIDEO: Ice Disappears, Walruses Head for Land

Data from the Landsat 8 Earth observation satellite provides a view of a phytoplankton bloom (green and blue swirls) near the Pribilof Islands off the coast of Alaska, in the Bering Sea. The turquoise waters are likely colored by a type of phytoplankton called coccolithophores.BLOG: Lakes Around the World Are Rapidly Disappearing

European satellite data shows that gravity has dipped in West Antarctica because of melting ice. The brownish areas in the graphic are places where the variation has been greatest.BLOG: Earth's Gravity Dips From Antarctic Ice Loss
In this picture taken by NASA astronauts, fires are creating a pall of smoke over the Amazon rainforest. The tan areas along the top of the photo are already-deforested sections of the Brazilian state of Mato Grosso.BLOG: Brazil Refuses To Join UN Pact To End Deforestation

At sunset, sea monkeys (brine shrimp, in white above) move en masse to the ocean surface, creating currents that have similar power to wind and tides, a new study reports. At sunset, the swim down away from predators, creating strong currents that affect circulation patterns around the world's oceans.Tiny Sea Monkeys Create Giant Ocean Currents
It’s weird to imagine giant hunks of ice floating in the waters off Miami. But that may have happened.
When the massive North American ice sheet from the last Ice Age began to melt 20,000 years ago, fresh water pooled in lakes, which were blocked in by glaciers and debris. But eventually, the lakes flooded over those barriers, and the waters carried icebergs into the northern Atlantic Ocean. While modeling studies by scientists in the past suggested that those icebergs drifted east toward Europe, a just-published article in Nature Geoscience provides evidence that the big pieces of ice drifted southward instead.
The researchers’ computer modeling is substantiated by the presence of massive scars that have been found on the ocean bottom off the continental shelf. Those marks were left by icebergs running aground, according to an analysis of Hill’s and Condron’s findings in Nature.
The researchers found that the icebergs drifted south because ocean currents are different today than they were tens of thousands of years ago. Today, most icebergs produced in the Arctic only drift as far as Newfoundland, where they encounter warmer currents and rapidly deteriorate, according to this primer on iceberg movement in the north Atlantic by the U.S. Coast Guard.
But back then, glacial floodwater running off North America formed a narrow current just about 62 miles thick, which flowed from Newfoundland southward toward Florida. It would have transported the icebergs.
