Description Magnetism is important in environmental studies for several reasons, the two most fundamental being that most substances exhibit some
form of magnetic behavior, and that iron is one of the most common elements in the Earth's crust. Once sequestered in a suitable material,
magnetic particles constitute a natural archive of conditions existing in former times. Magnetism provides a tracer of paleo-climatic
and paleo-environmental conditions and processes.
Environmental Magnetism details the occurrence and uses of magnetic
materials in the natural environment. The first half of the volume describes the basic principles. The second half discusses the applications
of magnetic measurements in various environmental settings on land, in lakes, in the ocean, and even various biological organisms.
Audience
An indispensable reference work for undergraduates, researchers, lecturers, and professionals in geomagnetism, geology, pedology, archeology, oceanography, climatology, and earth system science.
