Wildfires burned across Lebanon in mid-October, 2019. A pair of images taken just ten days apart by the European Space Agency's Sentinel-2A satellite show the burn scar from one of the larger wildfires. North of the fire scar is the country's capital, Beirut.

A video of a barred owl calling.

In this video, you can hear the honks and quacks of geese and ducks ring through the air, as birds fly in every direction above a wetland. This video was captured at Sacramento National Wildlife Refuge in November 2019, not long after geese and ducks began to arrive to spend the winter in the California Central Valley.

This video shows the proper procedure for performing cervical dislocation on a bat with clinical signs of white-nose syndrome to be submitted to a diagnostic laboratory for evaluation.

This video demonstrates the proper procedure for collecting a skin biopsy from a bat when conducting white-nose syndrome surveillance.

This video shows the proper technique for collecting a skin swab from a bat that is either roosting in place or is manually restrained for white-nose syndrome surveillance.

Environmental samples collected in or near bat roosting locations can be used to supplement samples collected from bats for surveillance for white-nose syndrome (WNS) (https://www.usgs.gov/centers/nwhc/science/white-nose-syndrome).

In the spring, winter sea ice thaws and moves offshore leaving the coast exposed to increased wave action and relatively warm water temperatures that, when in contact with the bluff, erodes the toe of the bluff.

In September of 2019, a 315 ton iceberg known as D28 broke free from the Amery Ice Shelf in Antarctica. The berg has a surface area of more than 600 square miles, roughly comparable to the size of the Hawaiian island of Oahu. It's the largest iceberg to calve from the ice shelf since the 1960s.

Prior to the Unoccupied Aircraft System (UAS) mission that collected a water sample from Halema‘uma‘u at Kīlauea's summit on October 26, reconnaissance UAS missions were flown. This video, taken over a period of 15 minutes, has been sped up 7 times to show the UAS as it approaches Halema‘uma‘u from the southwest.

The Unoccupied Aircraft System (UAS) that collected water from the crater lake in Halema‘uma‘u on October 26 was outfitted with both visual and infrared (thermal) cameras. This reconnaissance video shows fumarolic activity on the walls of the crater. Fumaroles appear light in color (yellow and white) in the visual imagery due to alteration of the crater wall rock.

In this October 26 reconnaissance survey, the Unoccupied Aircraft System (UAS) reaches the northeast part of the Halema‘uma‘u crater lake, where large rocks at the lake margin are often used to visually track the rising water level. Taken over a period of about 5.5 minutes, the survey is shown at 3 times the speed it was filmed.

This thermal video was captured by the UAS as it collected a water sample in Halema‘uma‘u, at Kīlauea's summit.
