Widespread outbreaks of foot-and-mouth disease and avian influenza occurred in South Korea during 2010. In response to the culling of many animals to attenuate the spread of disease, South Korea used mass burial sites to dispose of the large number of carcasses; consequently, concerns about groundwater contamination by leachate from these burial sites are increasing. Groundwater is one of the m...

Dynamic environments like seagrass habitats are characterised by continuous local erosion and burial processes, which may induce seagrass decline if disturbances become too intense or frequent. We aim to quantify for Zostera noltii the resilience of both the edge of a meadow and individual propagules to local-scale burial and erosion events. In a set of mesocosm and in situ manipulation experim...

The ultimate long-term goal of the ONR Mine Burial Prediction (MBP) program is the development of mine burial probability models that incorporate dynamic coupled processes, seafloor material properties, and different mine types. A second major thrust is on short-term applied research that will provide Fleet Aids for the operational Navy. The short-term effort will provide the operational Navy w...

A major goal of the ONR Mine Burial Prediction (MBP) Program is to provide the operational Navy simple models for predicting subsequent mine burial by scour which work with a known and useful degree of accuracy in regions of strategic interest, defined initially as sandy inner shelves dominated by waves. In order to be useful under real world conditions, such models must be reasonably accurate ...

The paper presents results of 21 deployments of an instrumented, mine-like cylinder over soft cohesive sediment seafloor at two sites. The focus of this work is the sediment penetration phase. The paper gives a statistical description of the sediment penetration dynamics and compares the observed behavior with predictions from an impact burial software package. It is shown that, due to simplifi...

Coastal dune plants are subjected to natural multiple stresses and vulnerable to global change. Some changes associated with global change could interact in their effects on vegetation. As vegetation plays a fundamental role in building and stabilizing dune systems, effective coastal habitat management requires a better understanding of the combined effects of such changes on plant populations....

The efficiency of gas transport to the free and upper troposphere in convective clouds is investigated in an axisymmetric dynamic cloud model with detailed microphysics. In particular, we examine the sensitivity of gas transport to the treatment of gas uptake by different ice hydrometeors. Two parameters are used to describe this uptake. The 5 gas retention coefficient defines the fraction of d...
