The USGS role in mapping the nation's submerged lands
Bill Schwab, John Haines
2004, Fact Sheet 2004-3082
The seabed provides habitat for a diverse marine life having commercial, recreational, and intrinsic value. The habitat value of the seabed is largely a function of the geological structure and related geological, biological, oceanologic, and geochemical processes. Of equal importance, the nation's submerged lands contain energy and mineral resources and...
Impacts of land use and climate change on carbon dynamics in south-central Senegal
Shu-Guang Liu, M. Kaire, Eric C. Wood, O. Diallo, Larry L. Tieszen
2004, Journal of Arid Environments (59) 583-604
Total carbon stock in vegetation and soils was reduced 37% in south-central Senegal from 1900 to 2000. The decreasing trend will continue during the 21st century unless forest clearing is stopped, selective logging dramatically reduced, and climate change, if any, relatively small. Developing a sustainable fuelwood and charcoal production system...
