Eyes on Earth Episode 42 – Rangelands of the U.S.

The extensive rangelands across the Western United States are threatened by invasive grasses, climate change, and altered fire regimes that can disturb the landscape. The largely semi-arid lands are also important for the survival of species that need undisturbed sagebrush ecosystems to thrive. But most satellite-based land cover datasets don’t offer the kind of detail

Eyes on Earth Episode 41 – Albedo

Albedo—the amount of incoming solar radiation reflected into space from the Earth’s surface—is a key measurement for surface temperatures and plant productivity. It also factors into weather forecasting and climate modeling. Landsat Science Team member Dr. Crystal Schaaf works with graduate and postdoctoral students to measure albedo using satellite data from the

Productivity of Black Oystercatchers in Southwest Alaska

The black oystercatcher, a keystone species in nearshore ecosystems, plays an important role in structuring nearshore systems and is highly susceptible to human disturbance. Current inventory and monitoring efforts may not adequately address the information needs for estimating long-term trends for this species. To address these issues, the goal of this research is to

Eyes on Earth Episode 40 – Landsat Collection 2

Landsat data is more useful today than at any other point in its nearly 50-year history. The USGS Collections strategy is a major reason why. Landsat Collections align and correct satellite acquisitions from 1972 through the present to make the data easier to work with through time. The USGS has now released Collection 2, an upgrade that improves geometric accuracy,

La encrucijada del fuego silvestre

La relación entre la gente y los incendios forestales siempre ha sido paradójica: el fuego es esencial como proceso ecológico y herramienta de gestión, pero también puede ser perjudicial para la vida y la propiedad. En consecuencia, los regímenes de incendios se han modificado a lo largo de la historia, mediante quemas intencionales para promover sus beneficios o mediante

Wildfire at the Crossroads

The relationship between people and wildfire has always been paradoxical: fire is an essential ecological process and management tool but can also be detrimental to life and property. Consequently, fire regimes have been modified throughout history through both intentional burning to promote benefits and active suppression to reduce risks. Reintroducing fire and its

Earth Observation User Case Study: Ladies of Landsat

Social scientists at the U.S. Geological Survey (USGS) Fort Collins Science Center – in collaboration with the USGS National Land Imaging Program – conduct Earth observation user case studies using qualitative research methods. Using standard scientific methods, they are better able to understand the variety of Earth observation users, including how they use and value

Eyes on Earth Episode 39 – Brazil’s Water Use

Brazil is a fascinating study in water use. Brazil uses roughly 72 percent of its water for irrigated agriculture, and its herds of cattle, pigs and poultry are among the largest in the world. Water management teams from that country’s National Water Agency have worked in recent years with researchers from the USGS EROS Center to learn how to map, and therefore more
