Wildlife Biologist Tyrone Donnelly searches the shoreline from a skiff in Izembek Lagoon while conducting avian influenza surveillance. Pacific black brant, seen flocking in the background, stage within the refuge each fall to take advantage of the abundance of eel grass as forage.

This bridge is at 75th Street east of Boulder showing Boulder Creek at flood stage (5000 cfs) on Friday, September 13, 2013. When looking west (upstream), the USGS streamgage is on the right.

Numerous rivers flooded during a significant September 2013 rain event along Colorado's Front Range, damaging or destroying several USGS streamgages. In response, USGS field crews measured flood flows, made gage repairs, and assessed sites to replace those gages destroyed. 

This flooded culvert is located on Monarch Road just east of the Diagonal Highway in Boulder, Colo.

One mission of the USCGC Healy is to conduct scientific research in the Arctic Ocean including cruises to recover sediment records of climate and ocean change.

Gravity corers are designed to recover sediment for paleoceanographic reconstruction and ecosystem research.

Permafrost-dominated coasts of Alaska have drastically changed as the result of coastal transgression and storm-surge flooding which can result in the loss of cultural sites and damage to infrastructure.  Photo by M.
