A. Gershunov, D.R. Cayan, S.F. Iacobellis
2009, Journal of Climate (22) 6181-6203
Most of the great California-Nevada heat waves can be classified into primarily daytime or nighttime events depending on whether atmospheric conditions are dry or humid. A rash of nighttime-accentuated events in the last decade was punctuated by an unusually intense case in July 2006, which was the largest heat wave...
NMR imaging of fluid exchange between macropores and matrix in eogenetic karst
L.J. Florea, K.J. Cunningham, S. Altobelli
2009, Ground Water (47) 382-390
Sequential time-step images acquired using nuclear magnetic resonance (NMR) show the displacement of deuterated water (D2O) by fresh water within two limestone samples characterized by a porous and permeable limestone matrix of peloids and ooids. These samples were selected because they have a macropore system representative of some parts of...
The use of local indicators of spatial association to improve LiDAR-derived predictions of potential amphibian breeding ponds
J.T. Julian, J.A. Young, J. W. Jones, C.D. Snyder, C. W. Wright
2009, Journal of Geographical Systems (11) 89-106
We examined whether spatially explicit information improved models that use LiDAR return signal intensity to discriminate in-pond habitat from terrestrial habitat at 24 amphibian breeding ponds. The addition of Local Indicators of Spatial Association (LISA) to LiDAR return intensity data significantly improved predictive models at all ponds, reduced residual error...

Erosional consequence of saltcedar control
K.R. Vincent, Jonathan M. Friedman, E.R. Griffin
2009, Environmental Management (44) 218-227
Removal of nonnative riparian trees is accelerating to conserve water and improve habitat for native species. Widespread control of dominant species, however, can lead to unintended erosion. Helicopter herbicide application in 2003 along a 12-km reach of the Rio Puerco, New Mexico, eliminated the target invasive species saltcedar (Tamarix spp.),...

John Franco Saraceno, Brian A. Pellerin, Bryan D. Downing, Emmanuel Boss, Philip A. M. Bachand, Brian A. Bergamaschi
2009, Journal of Geological Research (114)
Dissolved organic matter (DOM) dynamics during storm events has received considerable attention in forested watersheds, but the extent to which storms impart rapid changes in DOM concentration and composition in highly disturbed agricultural watersheds remains poorly understood. In this study, we used identical in situ optical sensors for DOM fluorescence...
Surface temperatures of the Mid-Pliocene North Atlantic Ocean: Implications for future climate
Harry J. Dowsett, Mark A. Chandler, Marci M. Robinson
2009, Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences (367) 69-84
The Mid-Pliocene is the most recent interval in the Earth's history to have experienced warming of the magnitude predicted for the second half of the twenty-first century and is, therefore, a possible analogue for future climate conditions. With continents basically in their current positions and atmospheric CO2 similar to early...
