How will sea level rise impact coastal ecosystems like salt marshes? Will plant species change and shift available habitat for local wildlife? Or will the marsh be completely inundated? USGS scientists are conducting extensive elevation and habitat surveys along the U.S. Pacific Coast, and using the data to model sea level rise impact for the next 100 years.

This time-lapse video shows the dramatic natural tidal cycles of a salt marsh in San Francisco Bay -- daily rhythms to which animals take refuge in high ground, and the marsh receives sediment and nutrients from the estuary. But what will happen to these marsh ecosystems under sea level rise scenarios?

movie shows a draining event in the lava pond within the Halema`uma`u vent cavity. The lava column exhibited cycles of filling and draining of the vent cavity, with each cycle lasting a few minutes. As the pond drains, lava cascades into a small hole on the east side (right) of the cavity floor.

Lava within the vent cavity in Halema`uma`u crater continues to be active, and occasionally displays remarkable filling and draining cycles. This Quicktime movie shows the draining portion of one of these cycles, captured in "nightshot" mode in order to see through the thick fume.

In this audio slideshow scientists cruise through tidal creeks, sample mangrove sites, pull sediment cores, and avoid swarms of mosquitoes while conducting studies and monitoring the largest subtropical wilderness in the United States, the Everglades.

USGS emeritus geologist Robert Christiansen describes his career working on Yellowstone geology from the 1960's through 2014. Bob's work along with his USGS colleagues revealed the details of Yellowstone's explosive volcanic past including mapping and dating of past super eruptions 2.1 million years ago, 1.3 million years ago and 640,000 years ago.

USGS emeritus geologist Patrick Muffler describes his career working on Yellowstone geysers and hydrothermal systems from the 1960's through 2014. Patrick's work along with his USGS colleagues revealed the details of Yellowstone's explosive volcanic past and how its spectacular geysers and other hydrothermal features work.
