Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, gives an overview of activity at Yellowstone during 2019, with an emphasis on the month of December.

Scientists at the U.S. Geological Survey Wetland and Aquatic Research Center (www.usgs.gov/warc) study important aspects of wetlands, such as the flow and quality of water, the chemistry of soil, and the plants and animals which call this ecosystem home.

This timelapse sequence shows two hours of activity at the water pond in Halema‘uma‘u, at Kīlauea's summit. Flow is evident along the sharp orange color boundary in the center of the pond, as well as along portions of the shoreline. The pond is 189 m (650 ft) long. The vido was taken on the eastern rim.

An overflight on December 18 provided aerial photographs of Kīlauea caldera, which were used to construct a 3D model. The water pond is visible in the deepest portion of Halema‘uma‘u crater. For scale, the water pond is 189 m (650 ft) long and approximately 600 m (1970 ft) below the western caldera rim.

The smell of a fresh cut Christmas tree can evoke visions of majestic evergreen forests teeming with winter wildlife. In truth, more than half of U.S. Christmas trees come from farms in Oregon, North Carolina, or Michigan. Cut Christmas Trees area commodity, tracked by the U.S. Department of Agriculture just like corn or soybeans.

Fires burned across California in late 2019. Fall is the state's most dangerous season for wildfires, propelled by dry and windy conditions. In recent years however, the fall fire season has been starting earlier and ending later. A series of images from the MODIS sensor on NASA's Terra and Aqua satellites show the Kincade Fire in northern California.

The degradation of coastal habitats, particularly coral reefs, raises risks by increasing the exposure of coastal communities to flooding hazards during storms. The protective services of these natural defenses are not assessed in the same rigorous economic terms as artificial defenses, such as seawalls, and therefore often are not considered in decision-making.

Low-lying island environments are particularly vulnerable to impacts from coastal hazards, including inundation (coastal flooding), whether the increased water levels are from episodic events (storm surge, wave run-up, king tides) or from chronic conditions (long term sea-level rise).

Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, describes activity at Yellowstone during the month of November 2019.

USGS Hawaiian Volcano Observatory scientists Frank Younger and Patricia Nadeau talk about sampling the water at the bottom of Halemaʻumaʻu, a crater at the summit of Kīlauea Volcano. The water appeared in July 2019 and has steadily risen since then.

The U.S. Fish and Wildlife Service’s (FWS) Everglades Headwaters National Wildlife Refuge (EHNWR) is strategically located in Florida to protect upland and wetland habitats.

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.
