Curt Storlazzi of the USGS explains how the water cycle pulled him into oceanography, and how his personal interests parallel his profession.
 

In this first installment of a two part series, The Arizona Water Science Center has developed new stream gaging methods that would measure flood flows remotely.

The Arizona Water Science Center details the history and development of the Continuous Slope-Area Method. Learn about the people and events that began these new advances in the field of stream gaging. 

USGS “supergages” are very complex. Continuous concentrations of nutrients and streamflow are measured at supergages and the information is available to the public in real-time.

A Record of Change—Science and Elder Observations on the Navajo Nation is a 25-minute documentary about collaborative studies using conventional physical sciences, combined with tribal elder observations to show that local knowledge and conventional science partnerships can effectively document ecosystem change and determine the resulting challenges to livelihoods.&

Warm summers and short winters are thawing permafrost in the Siberian tundra, causing soil erosion. As a result, the 800 meter wide Batagaika crater continues to expand.



At the USGS EROS Center, we study land change, operate the Landsat satellites, and maintain the longest, continuously acquired collection of images of the Earth's land surface.
