Gulf Stream warm-core rings (WCRs) impinging onto the Mid-Atlantic Bight (MAB) shelf edge can induce substantial water exchange between and slope seas. Combining satellite imagery idealized ocean models, this study investigates long-neglected influence of submarine canyons on WCR impingement process. Satellite images show onshore intrusion concentrated near MAB shelf-break canyons, indicating c...

and canyon sediments in several canyon reaches are contaminated with low-levels of radionuclides from hisFollowing the May 2000 Cerro Grande fire at Los Alamos, NM, toric LANL operations (Reneau et al., 1998). To mitisurface water control structures were constructed near Los Alamos to mitigate the transport of contaminant-bearing sediment toward the gate potential off-site migration of these se...

Abstract This work uses a high-quality 3D seismic volume from offshore Canterbury Basin, New Zealand, to investigate how submarine canyon systems can focus sub-surface fluid. The was structurally conditioned improve the contrast in reflections, preserving their lateral continuity. It reveals multiple pockmarks, eroded gullies and intra-slope lobe complexes occurring association with Waitaki Sub...

Submarine canyons that incise continental slopes are considered an important conduit for transport of suspended matter between shelf seas and deep-ocean. However, the exact mechanisms influencing deposition still largely unknown. We present moored observations current flows, acoustic echo intensity and, in high-resolution, temperature variation from two contrasting mooring sites 6.5 km apart ho...

Introduction: Valles Marineris is the largest tectonic canyon in the solar system, with a length of ~2500 km, depths of up to 10 km, and widths in excess of 100 km. The location of this canyon on Tharsis, and its orientation radial to the center of the rise suggests Tharsis control of Valles Marineris tectonism. Tharsis loading dominated the tectonic history of Mars, accounting for the radial g...

Urban trees play a crucial role in urban climate many aspects. However, existing research has not adequately explored the impact from time-evolving perspective, that is, tree growth over time. To bridge this gap, study investigates wind tunnel effects of tree-to-canyon foliage cover and relative height (0.32–1.1 times canyon height), mimicking trees, on conditions street canyons during moderate...
