Video of an active breakout of the Pu‘u ‘Ō‘ō episode 61G lava flow. This breakout is below the pali on the eastern margin of the flow. Pāhoehoe lava is flowing out from the base of an inflated tumulus, and has a characteristic blue tint to its surface crust (compared to the color of solidified lava around it).

A new HVO webcam provides improved views of Mauna Loa's summit caldera, Moku‘āweoweo, from the northwest rim. This time-lapse sequence shows a full day on Sunday, Dec. 3, starting and ending at midnight. The full moon and sensitive low-light ability of the camera allow good views throughout the nighttime hours.

• Sea otters are perhaps the best-known example of a "keystone predator".
• Sea otter behavior -- in particular diet specialization and limited mobility -- can mediate their effects on ecosystem dynamics.

Geoscience Australia's Acting Chief Scientist Adam Lewis talks about the value of Landsat data, the importance of free and open policy, and how analysis ready data is advancing earth observing science.
 

This video is of is a three-dimensional (3D) view of the Majuro Atoll, Republic of the Marshall Islands topobathymetric model which consists of topography (land elevation) and bathymetry (water depth). This video shows the importance of high-resolution, detailed topobathymetric models because the highest natural elevation for the Majuro Atoll is only three meters.

In this tutorial, we will show you how to use some advanced features in the LandsatLook Viewer. The site can be found at: http://landsatlook.usgs.gov/
 

The imagery featured in this video was created using data distributed by the National Aeronautics and Space Administration’s (NASA) Land Processes Distributed Active Archive Center (LP DAAC).

A USGS video about manatees reveals that while the animals may act like the cows of the sea, they also have more than a bit of the magical siren or mermaid about them.  Go for a serene swim.

An impressive channelized breakout appeared on the pali this morning, with lava emerging from the tube and swiftly flowing down the channel towards the base of the pali and coastal plain. Breakouts like these happen occasionally on the pali and are normally short lived.

A team of USGS scientists spent two weeks in the isolated Glacier Bay National Park, exploring one of the fastest-moving faults in North America.
 

This video shows typical spattering in the summit lava lake in Halema‘uma‘u Crater. Spattering is driven by the bursting of large gas bubbles. The surface crust tends to flow into the spattering sites, where the crust is shredded and sinks.

A helicopter overflight provided good view of Kīlauea caldera. This video starts from the east, near Kīlauea Iki, and heads west towards Halema‘uma‘u Crater. Spattering in the summit lava lake can be seen by the small orange spot in Halema‘uma‘u Crater. The gas plume from the lake is carried southwest by trade winds.

A routine helicopter overflight today provided good views of Mauna Loa's summit caldera. The video starts from the northeast end of the caldera, near North Pit, and travels southwest. In the southwest portion of the caldera, the prominent 1940 cone is followed by the 1949 cone on the caldera rim. The video ends with the steep walls of South Pit.

Off the coast of Louisiana, the small Isle de Jean Charles has nearly been swallowed by the ocean. Only about 2% of the land mass remains compared to it's size in the 1950s.

 

The U.S. Geological Survey (USGS) has improved Landsat data quality and usability through the creation of Analysis Ready Data (ARD) for the conterminous United States, Alaska, and Hawaii. Landsat ARD greatly reduces the preparatory work currently required to do time-series analysis for understanding landscape change for operational and science users.

LGSOWG #46 was held in Rapid City, South Dakota in 2017.
 

Out with the old, in with the new! A state-of-the-art aquatic science laboratory is being built on the shores of Lake Huron at the USGS Hammond Bay Biological Station (HBBS), one of seven field stations of the USGS Great Lakes Science Center, operated in partnership with the Great Lakes Fishery Commission.

• The U.S. is increasingly reliant on supply of mineral raw materials from other countries.
• Advanced technologies are increasingly making use of nearly the entire periodic table of the elements.
• Dynamic studies of critical and strategic mineral supply and demand can identify emerging potential supply risks.

CEOS Future Data Access & Architecture Team has outlined it's strategy for creating and distributing earth observations. These 5 initiatives will improve the way CEOS uses this data.
