Exploring the USGS Science Data Life Cycle in the Cloud
Executive Summary Traditionally in the USGS, data is processed and analyzed on local researcher computers, then moved to centralized, remote computers for preservation and publishing (ScienceBase, Pubs Warehouse). This approach requires each researcher to have the necessary hardware and software for processing and analysis, and also to bring all external data required for the workflow...
Mississippi Alluvial Plain Management and Environmental Support System
Providing reliable hydrologic understanding of a system as inherently complex as the MAP will require a numerical groundwater simulation model capable of simulating stream/aquifer interaction, updated and recalibrated over time and supported by a continuing program of data collection and evaluation. The US Geological Survey (USGS) has produced such a model for the larger Mississippi embayment...
