2011, Conference Paper, Proceedings of the 7th International Conference on Gas Hydrates (ICGH 2011)
Delineating sediment organic matter origins and sediment accumulation rates at gas hydratebearing and hydrocarbon seeps is complicated by the microbial transfer of 13C-depleted and 14Cdepleted methane carbon into sedimentary pools. Sediment 13C and 14C measurements from four cores recovered at Bullseye vent on the northern Cascadia margin are used to...
Pockmarks: Self-scouring seep features?
Laura L. Brothers, Joseph T. Kelley, Daniel F. Belknap, Walter A. Barnhardt, Peter O. Koons
2011, Conference Paper, Proceedings of the 7th International Conference on Gas Hydrates
Pockmarks, or seafloor craters, occur worldwide in a variety of geologic settings and are often associated with fluid discharge. The mechanisms responsible for pockmark preservation, and pockmarks? relation to active methane venting are not well constrained. Simple numerical simulations run in 2-and 3-dimensions, and corroborated by flume tank experiments, indicate...

Direction of unsaturated flow in a homogeneous and isotropic hillslope
Ning Lu, Basak Sener Kaya, Jonathan W. Godt
2011, Water Resources Research (47)
The distribution of soil moisture in a homogeneous and isotropic hillslope is a transient, variably saturated physical process controlled by rainfall characteristics, hillslope geometry, and the hydrological properties of the hillslope materials. The major driving mechanisms for moisture movement are gravity and gradients in matric potential. The latter is solely...

Methylmercury (MeHg) is a potent neurotoxicant and endocrine disruptor that accumulates in aquatic systems. Previous studies have shown suppression of hormone levels in both male and female fish, suggesting effects on gonadotropin regulation in the brain. The gene expression profile in adult female zebrafish whole brain induced by acute (96 h)...

Diel biogeochemical processes in terrestrial waters
David A. Nimick, Chris Gammons
2011, Chemical Geology (283) 1-2
Many biogeochemical processes in rivers and lakes respond to the solar photocycle and produce persistent patterns of measureable phenomena that exhibit a day–night, or 24-h, cycle. Despite a large body of recent literature, the mechanisms responsible for these diel fluctuations are widely debated, with a growing consensus that combinations...

David A. Nimick, Christopher H. Gammons, Stephen R. Parker
2011, Chemical Geology (283) 3-17
This review summarizes biogeochemical processes that operate on diel, or 24-h, time scales in streams and the changes in aqueous chemistry that are associated with these processes. Some biogeochemical processes, such as those producing diel cycles of dissolved O2 and pH, were the first to be studied, whereas processes producing...
