Advanced Dredging Techniques: Finding & Recovering Paystreaks
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!.

Advanced Dredging Techniques Part 2 The Right Approach
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".

Dredging in Coastal Waters (Balkema: Proceedings and Monographs in Engineering, Water and Earth Sciences)
Dredging has been closely linked to coastal developments since about halfway the 19th century when harbours and coastal waterways started to be constructed and dredged to facilitate marine trade and fisheries. The dredging techniques used in excavating shipping channels and harbours (usually to provide and maintain a required water depth) could also be applied in mining aggregates from the sea floor, in putting sub aquatic installations in place, and in land reclamation. Thus dredgers have been employed to provide sand, gravel, mud and mollusc shells for the construction of airfields, artificial islands, coastal defence works as well as to provide mineral ore to the mining industry and building materials like concrete and bricks. The varied use of dredgers has led to the development of a variety of dredger types, from small ones for small-sized inshore projects to very large sea going dredgers for very large projects with storage of the dredged material in the ship. The maximum depth of dredging the seafloor (120-130 m water depth) was reached off Newfoundland (Canada). This book, which is the first book dedicated to dredging and its environmental impact in the widest sense, contains chapters on dredging operations in the Netherlands, Belgium, the UK, Spain, the US, Hong Kong (China) and Singapore. Additional chapters discuss more general aspects such as dredging techniques, monitoring of dredging operations, and the prospects of dredging in a changing environment. Besides information on dredging activities in different areas, it will give insight into the activities and problems (environmental or other) involved in modern dredging..

Hammonton and Marigold (CA) (Images of America)
This is the story of one community and two towns: Hammonton and Marigold, companyowned dredger towns located 10 miles east of Marysville, California Their founding was a direct result of the gold rush of 1849 and the subsequent hydraulic mining that followed. The towns’ history was wrought by the families who inhabited them and the many men and women who would build their community together through the years. In Hammonton and Marigold, there was no upper or lower class; the people were all working for dredging companies and considered equals. Although the company towns were shut down and the families all displaced, in 1957, the community itself carried on to the present day, holding annual reunions and even publishing a quarterly newsletter..

Methods for the Study of Marine Benthos
Ecosystems of the benthic environment are a sensitive index to ecological change, and as such demand long-term and effective monitoring. Methods for the Study of Marine Benthos provides comprehensive information on the tools and techniques available to those working in areas where the declining health of the sea, depletion of marine resources and the biodiversity of marine life are major concerns.
In response to the need for increasingly detailed information on bottom-living communities, this fully revised new edition offers:
- Contributions from a broad range of internationally recognised experts
- New information for those compiling environmental impact statements, pollution assessments and working with eco-system management
- Two separate chapters on Imaging Techniques and Diving Systems
A vital tool for all marine and environmental scientists, ecologists, fisheries workers and oceanographers, libraries in all universities and research establishments where these subjects are studied and taught will find this book a valuable addition to their shelves..
