A Field Guide To Snow And Ice

People love snow. They love to ski and sled on it, snowshoe through it, and watch it fall from the sky. They love the way it blankets a landscape, making it look tranquil and beautiful. Few people, however, know how snow works. What makes it possible for us to slip and slide over, whether that’s falling on sidewalks or skiing down a mountain? What makes it cling to branches and street signs? What qualities of snow lead to avalanches? In A Field Guide to Snow, veteran snow scientist Matthew Sturm answers those questions and more. Drawing on decades of study, he explains in clear and simple ways how and why snow works the way it does. The perfect companion a ski trip or a hike in the snowy woods, A Field Guide to Snow will give you a new appreciation for the science behind snow’s beauty.

More than 400 photographs and line drawings illustrate every kind of atmospheric phenomenon: clouds of every type; storms, from cloudbursts to hurricanes; and sky colors.

How to find and prepare safe drinking water—anywhere, any time! Clean drinking water may be the last thing we think about day to day—but it’s the first thing we need in an emergency. Now, survival expert and biologist Joe Vogel explains how to find, treat, and store safe drinking water—even in the most extreme conditions. A Field Guide to Clean Drinking Water includes information about: ·The role of water in the body and how to calculate your water requirement ·Plants, geographical features, and more indicators that signal the presence of water ·How to collect dew and precipitation, and extract water from plants ·How to screen “raw water” for bacteria, pesticides, and other contaminants ·Every purifying method from boiling techniques to chemical disinfection ·And storage options that meet every need.Small enough to take anywhere—and broad enough to cover everything—this is a vital manual for backpackers, survivalists, and anyone who may need to know how to create their own drinking water.

Text and drawings explain how to identify wild animals by the tracks and other signs they leave.

Technical yet accessible, The Avalanche Handbook, 3rd Edition, covers the formation, character, effects, and control of avalanches; rescue techniques; and research on understanding and surviving avalanches. Illustrated with nearly 200 updated illustrations, photos and examples, the revised edition offers exhaustive information on contributing weather and climate factors, snowpack analysis, the newest transceiver search techniques, and preventative and protective measures, including avalanche zoning and control. It contains new information on the unique characteristics of alpine snow, snow slab instability, terrain variables, skier triggering of avalanches, and the nature of avalanche motion. Plus brand-new chapters on the elements of backcountry avalanche forecasting and the decision-making process.

As much as one-tenth of the world’s oceans are covered with sea ice, or frozen ocean water, at some point during the annual cycle. Sea ice thus plays an important, often defining, role in the natural environment and the global climate system. This book is a global look at the changes in sea ice and the tools and techniques used to measure and record those changes. The first comprehensive research done on sea-ice field techniques, this volume will be indispensable for the study of northern sea ice and a must-have for scientists in the field of climate change research.
