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.

Standard Fish Sampling Techniques
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.

Табиғи су айналымы - The Natural Water Cycle, Kazakh
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.

Scanning electron microscope image of Yellowstone drill core
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.

How measuring gravity on Mauna Kea helps us monitor Mauna Loa
A gravimeter measuring the force of gravity on Mauna Kea. These measurements are used to calibrate the instruments so they can precisely monitor changes in gravity from magma accumulation at Mauna Loa (background). USGS photograph taken on December 10, 2020.

The Ohio Department of Natural Resources and Michigan State University responded to a report from a commercial fisherman that grass carp were being captured in the Sandusky River. Researchers captured, tagged, and released grass carp to track their movements.

KWcam webcam animated GIF December 2, 2020
ANIMATED GIF: At Kīlauea summit, the KWcam webcam recorded several small color changes along the lake margin following rockfalls which impacted the lake surface. These rockfalls immediately followed a M3.1 earthquake Wednesday evening, December 2, at 5:59 p.m. HST. This animated image file (GIF) continuously loops two consecutive webcam images from 5:50 p.m.
