Foraminifera and thecamoebians are highly sensitive to environmental stress (natural or anthropogenic). This feature means that they can be used to biologically characterize a variety of freshwater and coastal marine environments. Due to their small size and hard shells, large quantities are also found fossilised in core samples, making them ideal for reconstructing past environmental conditions. This volume covers the specific environmental applications of these organisms and contains an introduction to the subject, detailed descriptions of methods and techniques and case studies. Written for non-specialists, this book will appeal to resource managers and consultants in the public and private sector who routinely work on coastal environmental problems. The book will also serve as a supplementary text for graduate students in many courses on environmental monitoring, ecological baseline studies and environmental science.

The first circumnavigation of the Americas was accomplished by the Canadian Survey Ship Hudson in an 11 month voyage (1969 - 1970). She carried an international team of marine scientists along with a large contingent of Bedford Institute of Oceanography (BIO) researchers to a number of remote and poorly-documented parts of four of the world's oceans, and to a group of unsurveyed fiords along the Chilean coast. The expedition established Canada's global-scale interest in the oceans including their biology, seafloor environments and the geological characteristics of their underlying basins. Dr. C. Mann and the Captain D. Butler, two Canadian federal government employees, were among the outstanding members of the Hudson 70 Coordintaing Committee that, respectively, guided the development of the expedition's scientific program and ensured safety-minded ship's operations under a range of weather and sea ice conditions. Data gathered during the circumnavigation were still being analyzed and published in the scientific literature as late as the early 1990s.
