For coral reefs, the threat of climate change and bleaching are bad enough. An international research group led by Cornell University has found that plastic trash – ubiquitous throughout the world’s o...
If it smells like food, and looks like food, it must be food, right?Not in the case of ocean-faring birds that are sometimes found with bellies full of plastic. But very little research examines ...
Green turtles are swallowing plastic at twice the rate they did 25 years ago, according to a University of Queensland study.
This activity familiarizes students with beach erosion, beach health, and the pervasive nature of plastic pollution. Students use measurements of sediment grain size and the buoyancy and density of ma...
The large-scale two-dimensional rheology of a sea ice pack arises from the local contact forces between adjacent does in convergence. It is conventionally modeled by a viscous-plastic constitutive rel...
The stability of the viscous–plastic rheology used extensively to model the dynamics of large–scale sea ice covers is studied. Using energy methods, it is shown that on a bounded domain, the viscous–p...
The standard model for sea ice dynamics treats the ice pack as a visco–plastic material that flows plastically under typical stress conditions but behaves as a linear viscous fluid where strain rates ...
Local contact interactions between sea ice floes can be modeled on the large scale by treating the pack as a two-dimensional continuum with granular properties. One such model, which has gained promin...
Study on the dynamic response,and especially the nonlinear dynamic response of stiffened plates is complicated by their discontinuity and inhomogeneity.The finite element method (FEM) and the finite s...
Three antennule morphotypes in the small cladoceran Bosmina longirostris have been considered to be hereditarily rigid phenotypes. However, we found that monoclonal populations of Bosmina collected f...
