Evidence for three-dimensional flux creep in thin-film Bi₂Sr₂CaCu₂O₈₊δ

Creator:: Karapetrov, Goran and Tate, Janet
Abstract:: We have measured sweep-rate-dependent magnetization hysteresis curves of thin-film Bi₂Sr₂CaCu₂O[subscript 8+δ] using a Hall probe magnetometer in an unconventional geometry. We find a structure in the response well below the three-dimensional to two-dimensional crossover field. The observed strong enhancement of the perpendicular field component’s creep rate in the presence of...

Aspect-dependent variations in regolith creep revealed by meteoric ¹⁰Be

Creator:: West, Nicole, Kirby, Eric, Bierman, Paul, and Clarke, Brian A.
Abstract:: Although variations in insolation and emergent feedbacks among soil moisture, vegetation, and soil cohesion are commonly invoked to explain topographic asymmetry that depends on aspect, few studies have directly quantified the efficiency of regolith transport along hillslopes of opposing aspect. We utilize meteoric ¹⁰Be concentrations in regolith (n = 74)...

Biological production in the NE Pacific and its influence on air-sea CO2 flux: Evidence from dissolved oxygen isotopes and O2/Ar

Creator:: Juranek, L. W., Quay, P. D., Feely, R. A., Lockwood, D., Karl, D. M., and Church, M. J.
Abstract:: We determine rates of gross photosynthetic O₂ production (GOP) and net community O₂ production (NCP) using the triple oxygen isotope and O₂/Ar approach on two spring and two late summer meridional transects of the NE Pacific. Observed GOP and NCP in the subtropical (89 ± 9 and 8.3 ± 1.3...

Are large macroalgal blooms necessarily bad? nutrient impacts on seagrass in upwelling-influenced estuaries

Creator:: Hessing-Lewis, Margot L., Hacker, Sally D., Menge, Bruce A., McConville, Sea-oh, and Henderson, Jeremy
Abstract:: Knowledge of nutrient pathways and their resulting ecological interactions can alleviate numerous environmental problems associated with nutrient increases in both natural and managed systems. Although not unique, coastal systems are particularly prone to complex ecological interactions resulting from nutrient inputs from both the land and sea. Nutrient inputs to coastal...

The Power of Three: Coral Reefs, Seagrasses and Mangroves Protect Coastal Regions and Increase Their Resilience

Creator:: Guannel, Greg, Arkema, Katie, Ruggiero, Peter, and Verutes, Gregory
Abstract:: Natural habitats have the ability to protect coastal communities against the impacts of waves and storms, yet it is unclear how different habitats complement each other to reduce those impacts. Here, we investigate the individual and combined coastal protection services supplied by live corals on reefs, seagrass meadows, and mangrove...

Identification of Nuclear Effects in Neutrino-Carbon Interactions at Low Three-Momentum Transfer

Creator:: Rodrigues, P. A., Demgen, J., Miltenberger, E., Aliaga, L., Altinok, O., Bellantoni, L., Bercellie, A., Betancourt, M., Bodek, A., Bravar, A., Budd, H., Cai, T., Carneiro, M.

W., Solano Salinas, C. J., Tagg, N., Tice, B. G., Valencia, E., Walton, T., Wolcott, J., Wospakrik, M., Zavala, G., Zhang, D., and MINERvA Collaboration
Abstract:: Two different nuclear-medium effects are isolated using a low three-momentum transfer subsample of neutrino-carbon scattering data from the MINERvA neutrino experiment. The observed hadronic energy in charged-current ν[subscript]μ interactions is combined with muon kinematics to permit separation of the quasielastic and Δ(1232) resonance processes. First, we observe a small cross...

Integrating satellite observations and modern climate measurements with the recent sedimentary record: An example from Southeast Alaska

Creator:: Addison, Jason A., Finney, Bruce P., Jaeger, John M., Stoner, Joseph S., Norris, Richard D., and Hangsterfer, Alexandra
Abstract:: Assessments of climate change over time scales that exceed the last 100 years require robust integration of high-quality instrument records with high-resolution paleoclimate proxy data. In this study, we show that the recent biogenic sediments accumulating in two temperate ice-free fjords in Southeast Alaska preserve evidence of North Pacific Ocean...

Selective laser melting of 304L stainless steel: Role of volumetric energy density on the microstructure, texture and mechanical properties

Abstract:: The role of volumetric energy density on the microstructural evolution, texture and mechanical properties of 304L stainless steel parts additively manufactured via selective laser melting process is investigated. 304L is chosen because it is a potential candidate to be used as a matrix in a metal matrix composite with nanoparticles...

Abstract:: We have investigated the depinning process of magnetic flux vortices in twinned crystals of YBa₂Cu₃O₇₋δ in intermediate applied magnetic fields parallel to the crystallographic c axis through precise resistivity measurements before and after fast-neutron irradiation. Of particular interest for each field is the power-law dependence of the electric field on...

Toward Quantifying the Increasing Role of Oceanic Heat in Sea Ice Loss in the New Arctic

Abstract:: The loss of Arctic sea ice has emerged as a leading signal of global warming. This, together with acknowledged impacts on other components of the Earth system, has led to the term “the new Arctic.” Global coupled climate models predict that ice loss will continue through the twenty-first century, with...
