The entire 50 square-kilometer (19 square-mile) Markham Ice Shelf off the coast of Ellesmere Island broke away in early August and is now adrift, while two sections of the nearby Serson Ice Shelf detached, reducing its mass by 60 percent or 122 square kilometers (47 square miles).

Announcement: Pipelines in Permafrost and Freezing Ground, 2nd ed.

New Release
Pipelines in Permafrost and Freezing Ground, Engineering Resource Library and Database Indexes
The timely release of the fourteen-volume book set provides engineers and geoscientists working in universities, research institutes, corporations, governments and regulatory bodies with an in-depth examination of the interdependence between cold climate infrastructure and the behaviour of freezing soils and permafrost-affected soils.

The Engineering Resource Library provides the user with additional insights into intricate concepts such as
• Soil strain and soil creep
• Hydrological and micromorphological properties
• Frost heave and frost bulb growth
• Thaw consolidation and pipeline relaxation
• Pressure in freezing soils and permafrost affected soils
• Bending stresses in buried pipelines
• Uplift resistance of pipelines in permafrost

The Library may be equipped with a suite of program modules and databases.
