Brave Wilderness host, Coyote Peterson, holds his hands in a tank of live sea lamprey while filming the first of two sea lamprey-focused episodes for the show’s YouTube channel. GLSC communications associate, Dr. Andrea Miehls, assisted the Brave Wilderness team while filming in multiple remote locations across northeastern Michigan.

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.

Examining environmental deoxyribonucleic acid (eDNA) in water samples has demonstrated promise for identifying fish species present in water bodies. However, whether or not this same approach can be used to assess relative abundance, biomass, and species composition in large (greater than [>] 200-hectare) waterbodies is unclear.

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.

Arc volcanoes often show evidence for new magma coming from the lower crust and interacting with old magma in the shallow crustal storage system.

Жер шарындағы су әрдайым қозғалыста болады. Гидрологиялық цикл ретінде белгілі табиғи су айналымы судың Жер бетіндегі және астындағы үздіксіз қозғалысын сипаттайды. Табиғатта су сұйық, мұз және бу күйінде кездеседі. Ол үнемі бір күйден екінші күйге ауысып отырады және бұл үдеріс миллиондаған жылдар бойы жүріп келеді.

The right side of the figure is an image of a small piece of the Y-9 core from the USGS 1967-68 drilling expedition to Yellowstone National Park. The black area was analyzed using a scanning electron microscope (SEM) at the University of Wyoming to determine mineralogy and dispersion of elements.

The western wall of Uzbekistan's Sardoba Reservoir breached on May 1st, 2020 after a week of heavy rain. Thousands were evacuated as water rushed north into farmland and villages across the central Asian country and into neighboring Kazakhstan. Imagery from Europe's Copernicus Sentinel-2 satellite shows water pooling across a wide area.
