Clear weather allowed HVO geologists to make observations and take measurements of the water pond at Kīlauea's summit. No major changes were observed, and the water level continues to slowly rise. Note the former HVO observation tower can be seen above the geologist's helmet. 

USGS hydrographer Brent Hanson wades out in freezing waters to collect flood measurements on the Sheyenne River near Cooperstown, North Dakota. Hanson reads an outside staff, which is a vertical graduated ruler used to calibrate the continuous readings of water level provided by electronic sensors. Water level is important information for communities living adjacent to

USGS hydrographer Spencer Wheeling gets equipment ready to collect a flood water-quality sample on the Wild Rice River near St. Benedict, North Dakota. Collecting water-quality samples helps communities assess the sources and fate of contaminants in aquatic systems, to protect and enhance water resources for human health, aquatic health and environmental quality.

Key used in an educational lesson plan for identifying the composition and condition of corals and coralline algae in a core. (a) Two examples of Pocillopora in good taphonomic condition (<50% erosion or encrustation of the skeleton). Intervals in cores during which Pocillopora skeletons dominate and are in good condition represent times of good coral growth and active

Scanning electron microprobe images show the complexity of tiny Icelandic ash grains (150 micron, or 0.006 inch). Image (a) shows a dense and blocky grain, and (b) shows a foamy grain.

This section of brown Icelandic soil (top) contains 800 years of ash deposits erupted from five different volcanoes. The black layers, 5-10 cm (2-4 in) thick, are from Katla Volcano. A white arrow points to a closeup of the 1755 Katla ash deposit (lower left). The ash looks like specks of dust in the sample bag (lower right), but microprobe imaging reveals how complex

Rockaway Beach, New York is heavily developed, has seawalls and groins and is regularly nourished. It hasn’t changed much over 20 years. The shoreface is steep and sediment cover doesn’t extend far from shore—likely the result of being fixed in place for decades. USGS scientists collect geologic and morphologic data from this island’s shoreface. The shoreface is an

Fire Island, New York is sparsely populated and regularly nourished, but has few modifications that impede natural sediment exchanges. Shoreface geomorphology reflects past periods of seaward progradation and alongshore extension resulting in a relatively sediment-rich shoreface. USGS scientists collect geologic and morphologic data from this island’s shoreface. The

Cedar Island, Virginia is an uninhabited barrier that has migrated landward approximately 15-30 meters per year since 1984 due to its low sediment supply. The shoreface slope is gradual but almost entirely devoid of island sediment - both responses to its recent, rapid retreat. USGS scientists collect geologic and morphologic data from this island’s shoreface. The

These data are based on geomorphic investigation and measure distance (in kilometers) of cross-shore accretion. Q_S is the flux of sand to the beach, and Q_D is the flux of sand from the beach to the active dune. Yellow represents sand, blue represents

A U.S. Army Air Corps biplane is prepared for a mission to drop bombs on a lava flow advancing toward Hilo during the Mauna Loa 1935 eruption. Below the plane is one of 20 demolition bombs (center) dropped in an attempt to disrupt and redirect the Humu‘ula lava flow, and two of the 20 "pointer bombs" (left and right) that were used for aiming purposes.
