Permafrost, Ice Sheets, And Sea Level, Beth Caissie, Julie Brigham-Grette Jan 2010

Permafrost, Ice Sheets, And Sea Level, Beth Caissie, Julie Brigham-Grette

IPY STEM Polar Connections

Sea level rise and inhabited coastlines. Ice shelves and sea ice do not contribute to sea level but they can buttress the land ice sheets from rapid retreat. Causes of Sea Level Rise:

•Melting of glaciers, ice caps, ice sheets •Thermal expansion of sea water ••Small scale changes due to anthropogenic land water storage (damming rivers, over-pumping of water and fuels, wetland and forest destruction) •Relative changes in sea level due to tectonic movements (land subsidence or rebound)

Teacher’S Guide: Penguins Of Antarctic Region, Marie Silver Jan 2010

Teacher’S Guide: Penguins Of Antarctic Region, Marie Silver

IPY STEM Polar Connections

These activities help to connect science learning with real world issues through a study of the Antarctic region. By studying the penguins of the South Pole region you can tap students’ interest in a charismatic macrospecies through demonstrating their adaptation to ongoing climate changes and human activity. A number of current research projects at Antarctic research stations can be accessed online and the data used to demonstrate key concepts of feeding behavior, migration, breeding and population dynamics. The attached activity is in three parts and includes one hands-on demonstration, several mapping exercises and some data interpretation. These activities also provide …

Numerical Modeling Of Fracturing In Non-Cylindrical Folds: Case Studies In Fracture Prediction Using Structural Restoration, John Ryan Shackleton May 2009

Numerical Modeling Of Fracturing In Non-Cylindrical Folds: Case Studies In Fracture Prediction Using Structural Restoration, John Ryan Shackleton

Open Access Dissertations

This thesis contains several distinct studies aimed at better understanding fracturing in compressional fault-cored folds. At outcrops of growth strata in the Oliana anticline in the Spanish Pyrenees, the relationship of two joint sets may reflect changing mechanical properties (i.e. via diagenesis) during the folding process. Using a Schmidt hammer, I assess the rigidity contrast between the individual units and suggest that late-stage, throughgoing joints formed in strata with conditions similar to those of the present day and that early, bed-contained joints formed when the rigidity contrast between beds was significantly greater than the present day contrast. Modeling algorithms that …
