Awesome Dredging Album and Music Offers

Long-experienced author, Dave McCracken, shares a wealth of insight and USEFUL information about dredging for gold. Of primary importance to any gold dredger are the chapters on prospecting in hard-packed, natural streambeds, and production dredging. But Dave also covers other very valuable information, such as: which boulders to look for in the streambed that will help you locate pay streaks; a complete rundown on underwater boulder winching techniques; deep water dredging; fast water dredging; cold water dredging; how to care for, modify and repair wet or dry suits, hot water systems; recovering 100% of the free gold out of dredge concentrates with minimal time and effort; and a long list of new tricks of the dredging trade. Dave also carefully outlines the fundamentals of how to go about being continuously successful in gold dredging. His essay about positive stress ("gold fever") is reason all by itself to read this book! This book should rightfully be called: "What every gold dredger should know - Part 2".

In this book, Dave McCracken thoroughly covers paystreaks-what they are, how they form, where in the river that you will find them, and how to dredge them up without leaving paying quantities of gold behind. This book, just like McCracken's other mining books, is completely packed with useful information for any gold dredger; but the technology concerning paystreaks, standard sampling procedure, and standard dredging procedure is absolutely vital to each and every gold dredger if he or she wants to get into paying quantities of gold continuously. If you don't do anything else this year to improve your gold dredging skill, buy this book and study it well: You will not be disappointed!.

For this second edition of the highly successful 'Dredging: A Handbook for Engineers', Nick Bray and his co-authors have fully updated and expanded the book which covers all aspects of modern dredging including operating methods, outputs, costs, contracts and the impact on the environment. Planning and implementing dredging projects, including pre-contract works, is also well covered. The book is generously illustrated with line drawings, photographs and tables, and a useful bibliography appears at the end of each chapter. This definitive handbook will prove invaluable to engineers and managers alike, both as an initial introduction to this specialised topic and as a reference for years to come.

The ocean resources on which we depend for food, commerce, transport, and recreation are not limitless, nor are ocean waters capable of continual self-cleansing. Alex Lechich makes it painfully clear that the world's oceans are, in fact, in desperate peril: fish stocks are overexploited, other marine resources are depleted, habitat is being lost or its resilience is declining, water contamination is pervasive, and the economic and human costs related to ocean decline are escalating. All of these considerations contributed to a dangerous shipping crisis that threatened the Port of New York and New Jersey's very viability in the early 1990s.

Modern navigational channels and shipping berths must be periodically dredged. Historically, the millions of cubic yards of frequently contaminated muds and sands regularly removed in this way have been dumped at sea. When the U.S. Environmental Protection Agency imposed tighter restrictions on ocean dumping in the 1990s, almost all dredging halted, putting the Port of New York and New Jersey's standing as one of the busiest cargo ports in the nation at risk. The crisis was temporarily abated by a Vice President Al Gore-sponsored agreement between environmental groups and government agencies, but many of the original problems remain.

Accessibly written by a scientist intimately familiar with these dramatic events, A Storm in the Port explains the origins, escalation, and specific and broad implications of this port crisis. Lechich explains the science and environmental concerns that come into play, considers solutions to complex dilemmas, and makes clear the desperate need for new ocean policies that tread the delicate line between protecting the world's oceans and preserving their economic and recreational value. This urgently needed book is poised to heighten regional and national interest in ocean policy and related issues, and promote the sustainable use and enjoyment of the world's oceans. It will be essential reading for professional and lay students of oceans and environmental policy..

The California Gold Rush began to decline about 1865, but the magical lure of gold has never declined. Today, modern scuba diving equipment and techniques make it possible to recover gold inaccessible to the original, hearty, hardworking gold miners. This book gives personal accounts of how to do it, where to look, and the equipment that brought the author the best results..
