Development and evolution of detachment faulting along 50 km of the Mid-Atlantic Ridge near 16.5N

This is the accepted manuscript. An edited version of this paper was published by AGU. Copyright 2014 American Geophysical Union.A multifaceted study of the slow-spreading Mid-Atlantic Ridge (MAR) at 16.5ºN provides new insights into detachment faulting and its evolution through time. The survey included regional multibeam bathymetry mapping, high-resolution mapping using AUV Sentry, seafloor imaging using the TowCam system, and an extensive rock-dredging program. At different times, detachment faulting was active along ~50 km of the western flank of the study area, and may have dominated spreading on that flank for the last 5 Ma. Detachment morphologies vary and include a classic corrugated massif, non-corrugated massifs, and back-tilted ridges marking detachment breakaways. High-resolution Sentry data reveal one other detachment morphology; a low-angle, irregular surface in the regional bathymetry is shown to be a finely corrugated detachment surface (corrugation wavelength of only tens of meters and relief of just a few meters). Multi-scale corrugations are observed 2-3 km from the detachment breakaway suggesting that they formed in the brittle layer, perhaps by anastomosing faults. The thin wedge of hanging wall lavas that covers a low-angle (6º) detachment footwall near its termination are intensely faulted and fissured; this deformation may be enhanced by the low-angle of the emerging footwall. Active detachment faulting currently is limited to the western side of the rift valley. Nonetheless, detachment fault morphologies also are present over a large portion of the eastern flank on crust > 2 Ma indicating that within the last 5 Ma parts of the ridge axis have experienced periods of two-sided detachment faulting.This work was supported by the National Science Foundation grant number OCE-1155650

Lasers and optics: Looking towards third generation gravitational wave detectors

Third generation terrestrial interferometric gravitational wave detectors will likely require significant advances in laser and optical technologies to reduce two of the main limiting noise sources: thermal noise due to mirror coatings and quantum noise arising from a combination of shot noise and radiation pressure noise. Increases in laser power and possible changes of the operational wavelength require new high power laser sources and new electro-optic modulators and Faraday isolators. Squeezed light can be used to further reduce the quantum noise while nano-structured optical components can be used to reduce or eliminate mirror coating thermal noise as well as to implement all-reflective interferometer configurations to avoid thermal effects in mirror substrates. This paper is intended to give an overview on the current state-of-the-art and future trends in these areas of ongoing research and development.NSF/PHY0555453NSF/PHY0757968NSF/PHY0653582DFG/SFB/407DFG/SFB/TR7DFG/EXC/QUES

Dialytic transport of carboxylic acids through an anion exchange membrane

The transport behavior of five carboxylic acids of relevance in biotechnology (acetic, propionic, lactic, oxalic, citric) in diffusion dialysis and neutralization dialysis through an anion exchange membrane is investigated. The dependence of acid anion flux on base concentration in neutralization dialysis is analyzed in terms of two limiting situations (boundary layer control and membrane control) by an empirical two-parameter flux equation in formal analogy to a Langmuir function. When coupled to a life fermenter, neutralization dialysis is a means to control the pH of the fermentation medium. By removing biotoxic acids, it improves microbial productivity, as exemplified with the Propioni system producing vitamin B_1_2 and propionic acid.
