Bedforms and Mine Burial
The generation and migration of bedforms (eg, ripples, megaripples and sand bars) on sandy bottoms in the nearshore (0-8 m water depths) provides a mechanism for objects on the seafloor to become buried. As a bedform migrates past a mine, the mine will fall to the low point of the bedform trough before subsequently being buried by the passage of the following bedform crest. The statistics of mi...
متن کاملHypothermia during Avalanche Burial
Core body temperature cooling during avalanche burial results in hypothermia, and further core temperature cooling during extrication and evacuation of an avalanche burial victim may result in more severe hypothermia. We performed two studies measuring the rate of core body temperature cooling during snow burial and after extrication from snow burial. Subjects were completely buried in a large ...
متن کاملBedform Dynamics and Mine Burial
Large bedforms in the nearshore (with heights of 10 – 50 cm and lengths of 1-10 m) are observed to occur frequently and to be ubiquitous throughout the surf zone (e.g., Clifton et al. 1971, Gallagher et al. 2002, Hay and Wilson 1994, Thornton et al. 1998). However, their dynamics are poorly understood and they are generally neglected in models of sediment transport, morphology change and nearsh...
متن کامل1Residential Burial in Global Perspective
While the study and interpretation of mortuary practices have long been important parts of archaeological analyses, rarely has residential burial – the practice of burying the deceased in and around houses – been a specific focus of investigation. Here, we examine some of the global contexts in which residential burial has occurred and discuss the different ways that archaeologists have interpr...
متن کاملCarbon sequestration via wood burial
To mitigate global climate change, a portfolio of strategies will be needed to keep the atmospheric CO2 concentration below a dangerous level. Here a carbon sequestration strategy is proposed in which certain dead or live trees are harvested via collection or selective cutting, then buried in trenches or stowed away in above-ground shelters. The largely anaerobic condition under a sufficiently ...
