Kilauea's active summit vent is on the southeast side of Halema'uma'u Crater. In this photo, the floor of Halema'uma'u stretches out beyond the vent, and the summit of Kilauea Volcano is at upper right. The observation tower at the Hawaiian Volcano Observatory is the highest bump in the photo at Kilauea's summit.

A close-up view of the lava stream as seen through a lava tube skylight near the top of the Pulama pali. The lava is moving from right to left, and skylight opening is about 1 m (3 ft) across.

Great Lakes water availability studies conducted by the U.S. Geological Survey aim to help characterize how much water the Basin has now, how water availability is changing, and how much water it can expect to have in the future.

Two Cladonia lichen species, C. stellaris and C. rangiferina are pictured here among some blueberry plants in Newfoundland.  Lichens -- which are often mistaken for moss -- are unusual plant-like organisms that are actually symbioses of fungi, algae and bacteria living together.

Equipped with a multibeam bathymetric system and acoustic Doppler current profiler, the research vessel Lucien Brush was deployed to make comprehensive maps of the potential spawning area.  In order to collect precise location data, a base station is set-up within view of the area to be mapped.  Luckily, a sandbar was still peaking above the river’s surfac

Specialized, directional, underwater microphones, or hydrophones are lowered into the water to “hear” acoustic tags implanted in pallid sturgeon.
