Variability and trends in Mountain Snowpack in Western North America
Snow course and SNOTEL measurements of spring snowpack, corroborated by a physically-based hydrologic model, are examined here for climate-driven fluctuations and trends during the period 1916-2002. Much of the mountain West has experienced declines in spring snowpack, especially since mid-century, and despite increases in winter precipitation in many places. Analysis and modeling shows that cl...
متن کاملCenozoic Paleoclimate on Land in North America
Paleotemperature and paleoprecipitation over the past 40 m.yr. can be inferred from the degree of chemical weathering and depth of carbonate nodules in paleosols of Oregon, Montana, and Nebraska. Paleosol records show that late Eocene (35 Ma), middle Miocene (16 Ma), late Miocene (7 Ma), and early Pliocene (4 Ma) warm climatic episodes were also times of a wet climate in Oregon, Montana, and Ne...
متن کاملCenozoic tectonics of western North America controlled by evolving width of Farallon slab.
Subduction of oceanic lithosphere occurs through two modes: subducting plate motion and trench migration. Using a global subduction zone data set and three-dimensional numerical subduction models, we show that slab width (W) controls these modes and the partitioning of subduction between them. Subducting plate velocity scales with W(2/3), whereas trench velocity scales with 1/W. These findings ...
متن کاملEarly Cenozoic Differentiation of Polar Marine Faunas
The widespread assumption that the origin of polar marine faunas is linked to the onset of major global cooling in the Late Eocene-Early Oligocene is being increasingly challenged. The Antarctic fossil record in particular is suggesting that some modern Southern Ocean taxa may have Early Eocene or even Paleocene origins, i.e. well within the Early Cenozoic greenhouse world. A global analysis of...
متن کاملERDC TN-EMRRP-ER-21 "Russian Olive Biology, Invasion, and Ecological Impacts in Western North America"
INTRODUCTION: The United States Army Corp of Engineers (USACE) Ecosystem Management and Restoration Research Program (EMRRP) is supporting a nationwide effort to address the impact of invasive woody plant species on ecosystem restoration, and more specifically, to determine mechanisms to address the most regionally prevalent invasive species impacting restoration activities. The research effort...
