A Miocene pollen and spore flora representing raised island, intertidal, and beach-ridge environments is described from depths of 670 to 2,500 feet beneath Eniwetok Atoll.
The purpose of the PEACE Program was to provide highly credible, multidisciplinary set of geologic, geophysical, and material-properties data in order to identify crater dimensions and features for two high-yield nuclear craters and to better understand the dynamic processes that initially formed these craters and that subsequently modified them. These data are essential to the Department of Defense to better understand the survivability of strategic defense systems in the event of a nuclear attack. Physical Stratigraphic Framework; Sr-Isotope Framework; Mineralogy; Organic Content; Insoluble Residues; Downhole Geophysical Logs; Borehole gravity Surveys; Seismic Reference Surveys; Benthic Samples; Additional Paleontologic Studies; Radiation Chemistry ; Additional Sea-Floor Observations; Crater Interpretation.
A compilation of studies originating from the Pacific Enewetak Atoll Crater Exploration (PEACE) Program, prepared in cooperation with the Defense Nuclear Agency.
This book offers a timely overview and synthesis of biogeographic patterns of plants and fungi and their mycorrhizal associations across geographic scales. Written by leading experts in the field, it provides an updated definition of mycorrhizal types and establishes the best practices of modern biogeographic analyses. Individual chapters address the basic processes and mechanisms driving community ecology, population biology and dispersal in mycorrhizal fungi, which differ greatly from these of prokaryotes, plants and animals. Other chapters review the state-of-the-art knowledge about the distribution, ecology and biogeography of all mycorrhizal types and the most important fungal groups involved in mycorrhizal symbiosis. The book argues that molecular methods have revolutionized our understanding of the ecology and biogeography of mycorrhizal symbiosis and that rapidly evolving high-throughput identification and genomics tools will provide unprecedented information about the structure and functioning of mycorrhizal symbiosis on a global scale. This volume appeals to scientists in the fields of plant and fungal ecology and biogeography.
Biology and Geology of Coral Reefs, Volume I: Geology 1 focuses on the evolution, reef types, geology, and structural and tectonic factors causing the development of coral reefs. The selection first offers information on the coral reefs of the Caribbean and Indian Ocean, including evolution, physical environment, coral diversity, reef communities, reef types and zonation, and reef morphology and sea-level change. The manuscript then takes a look at the Bikini and Eniwetok Atolls in Marshall Islands; geomorphology and geology of coral reefs in French Polynesia; and the coral reefs of New Caledonia. The publication examines the coral reefs of the New Guinea region and waters of the Great Barrier Reef province. Topics include climate, seasonal variations in temperature and salinity, and water masses in the Coral Sea and their effect on the Great Barrier Reef. The book also ponders on the geomorphology of Eastern Queensland in relation to the Great Barrier Reef; structural and tectonic factors influencing the development of coral reefs off Northeastern Queensland; and sediments of the Great Barrier Reef province. The selection is a vital source of information for marine biologists and readers interested in the geology, evolution, physical environment, and diversity of coral reefs.
