This timelapse sequence shows the water pond in Halema‘uma‘u Crater, at Kīlauea's summit, between November 1, 2019, and March 26, 2020. Over this time the water level rose approximately 14 meters (46 feet), equivalent to 67 cm (about 2 feet) per week. The timelapse shows one image per day (with a few cloudy images removed), and is looped several times.

Enhancing ecological connectivity - the degree to which landscapes facilitate the movement of the organisms within them - is a frequently recommended strategy for conserving wildlife populations into the future.

Antarctica has been the source for a host of fascinating satellite imagery in recent months. We've offered scenes from the southern solstice, images of icebergs adrift, and shots of pooling meltwater during some of the warmest days on record for the frozen continent. An international team of scientists onboard a U.S.

Stormy weather moved through the islands over the past day, producing snow at the higher elevations of Mauna Kea and Mauna Loa. This sequence shows the webcam images at the summit of Mauna Loa, and the variable weather throughout the day.

Tall and contiguous coastal dunes can substantially mitigate storm surge and flooding near our coasts. Understanding the position and height of dunes, as well as how these features change over time, is critical to the USGS mission of predicting impacts to coastal infrastructure and habitat caused by storms and hurricanes.

This Landsat 8 image from May 24th, 2017 shows an enthralling New Zealand landscape. Snow-capped mountain peaks, forests, farmland, and fog highlight the picturesque view of New Zealand's North Island. The scene was downloaded on March 9th, 2020 one of over 29,000 Landsat scenes downloaded worldwide that day. But this scene is special.

Landsat recently captured the most widespread meltwater pooling ever recorded on Antarctica's George VI Ice Shelf. Some melting is expected during the Antarctic summer, but the sheer extent of the stunning aqua ponds that have appeared amid the continent's warmest summer on record is remarkable.

Cattail (Typha) is an iconic emergent wetland plant found worldwide. By producing an abundance of wind-dispersed seeds, cattail can colonize wetlands across great distances, and its rapid growth rate, large size, and aggressive expansion results in dense stands in a variety of aquatic ecosystems such as marshes, ponds, lakes, and riparian areas.
