Trends in cation, nitrogen, sulfate and hydrogen ion concentrations in precipitation in the United States and Europe from 1978 to 2010: a new look at an old problem

Creator:: Lajtha, Kate and Jones, Julia A.
Abstract:: Industrial emissions of SO₂ and NOₓ, resulting in the formation and deposition of sulfuric and nitric acids, affect the health of both terrestrial and aquatic ecosystems. Since the mid-late 20th century, legislation to control acid rain precursors in both Europe and the US has led to significant declines in both...

Fingered Flow in Two Dimensions 2. Predicting Finger Moisture Profile

Creator:: Selker, J., Parlange, J.-Y., and Steenhuis, T.
Abstract:: An exact integral solution for the moisture profile in growing fingers in sandy soil is derived from Richards' equation. The solution provides moisture content along a finger as a function of position and time and provides applicable results, including the calculation of the asymptotic matric potential of a growing finger...

Density fractionation and 13C reveal changes in soil carbon following woody encroachment in a desert ecosystem

Creator:: Throop, Heather L., Lajtha, Kate, and Kramer, Marc
Abstract:: Woody encroachment has dramatically changed land cover patterns in arid and semiarid systems (drylands) worldwide over the past 150 years. This change is known to influence bulk soil carbon (C) pools, but the implications for dynamics and stability of these pools are not well understood. Working in a Chihuahuan Desert...

Linking aboveground net primary productivity to soil carbon and dissolved organic carbon in complex terrain

Creator:: Peterson, Fox S. and Lajtha, Kate J.
Abstract:: Factors influencing soil organic matter (SOM) stabilization and dissolved organic carbon (DOC) content in complex terrain, where vegetation, climate, and topography vary over the scale of a few meters, are not well understood. We examined the spatial correlations of lidar and geographic information system-derived landscape topography, empirically measured soil characteristics,...

Thermal reaction norms for growth vary among cohorts of Pacific cod (Gadus macrocephalus)

Creator:: Hurst, Thomas P., Munch, Stephan B., and Lavelle, Kate A.
Abstract:: While much effort has been directed at determining the spatial scales of adaptation in thermal reaction norms for growth, it is widely assumed that these reaction norms have high temporal stability. Water temperatures in the Gulf of Alaska in 2007 were the coldest on record since the mid-1970s and we...

Stable isotopes (¹⁸O/¹⁶O) and ⁸⁷Sr/⁸⁶Sr ratios in pore fluids of the Chile Triple Junction accretionary prism : implications for diagenesis and fluid migration

Creator:: Zheng, Yan, Froelich, Philip N., Torres, Marta E., and Dia, Aline N.
Abstract:: Oxygen and strontium isotopic composition of sedimentary pore fluids obtained by drilling at the Chile Triple Junction have been used to obtain information on the diagenesis and transport mechanisms of fluids. Samples were collected from three sites located on an east-west transect of the pre-collision zone (Sites 859, 860, and...

Benthic foraminiferal stable isotope stratigraphy of Site 846 : 0-1.8 Ma

Creator:: Mix, Alan C., Le, J., and Shackleton, N. J.
Abstract:: A stable-isotope stratigraphy at Site 846 (tropical Pacific, 3°06'S, 90°49'W, 3307 m water depth), based on the benthic foraminifers Cibicides wuellerstorfi and Uvigerina peregrina, yields a high-resolution record of deep-sea δ¹⁸O and δ¹³C over the past 1.8 Ma, with an average sampling interval of 3 k.y. Variance in the δ¹⁸O...

Spatial and temporal variability of late Neogene Equatorial Pacific carbonate : ODP Leg 138

Creator:: Hagelberg, T. K., Pisias, Nicklas G., Mayer, L. A., Shackleton, N. J., and Mix, Alan C.
Abstract:: High resolution, continuous records of GRAPE wet bulk density (a carbonate proxy) from Ocean Drilling Program Leg 138 provide one the opportunity for a detailed study of eastern equatorial Pacific Ocean carbonate sedimentation during the last 6 m.y. The transect of sites drilled spans both latitude and longitude in the...

Involving the users remotely : an exploratory study using asynchronous usability testing

Creator:: Filar Williams, Beth and Valla, Sara
Abstract:: Open Educational Resources (OER) are increasingly used in the higher education landscape as a solution for a variety of copyright, publishing and cost-prohibiting issues. While OERs are becoming more common, reports of usability tests that evaluate how well learners can use them to accomplish their learning tasks have lagged behind....

Data report : trace element, Sr isotope, and Ge/SI composition of fluid and sediments in ridge-flank low-temperature hydrothermal environments

Creator:: Hulme, Samuel M., Wheat, C. Geoffrey, Coggon, Rosalind M., and McManus, James
Abstract:: The data presented in this report demonstrate significant improvements in the ability to constrain trace element and Sr isotopic concentrations in sediments overlying ridge-flank hydrothermal systems. Improved sampling methods orchestrated by the Integrated Ocean Drilling Program (i.e., advanced piston coring and anoxic sample processing) enabled the collection of reactive pore...
