The Ocean Drilling Program (ODP) published Volume 157 of the Initial Reports of the ODP Proceedings. This volume covers Leg 157 of the cruises of the Drilling Vessel JOIDES Resolution, which took place from 24 July to 23 September 1994, focusing on the Gran Canaria and Madeira Abyssal Plain. The volume includes scientific and engineering results from the drilling activities, with a focus on geological and geophysical structures, sediment history, and areas of major geophysical activity such as mid-ocean ridges and hydrothermal circulations. The publication includes detailed reports on the drilling sites, including site summaries, principal results, background and objectives, underway geophysics, operations, lithostratigraphy, biostratigraphy, paleomagnetism, inorganic and organic geochemistry, physical properties, downhole measurements, and sediment accumulation rates. The volume also includes core descriptions, smear slides, thin sections, and log data. The CD-ROM included with the volume contains depth-shifted and processed logging data, as well as shipboard gamma-ray attenuation porosity evaluation (GRAPE), index property, magnetic susceptibility, and natural gamma, P-wave, and reflectance data of cores collected during Leg 157. The publication was prepared by the Ocean Drilling Program, Texas A&M University, as an account of work performed under the international ODP, which is managed by Joint Oceanographic Institutions, Inc., under contract with the National Science Foundation. The publication includes acknowledgments of the contributions of the ship's crew, the ODP staff, and the scientific parties involved in the drilling activities. The publication also includes a foreword by Joint Oceanographic Institutions, Inc., and a list of member organizations of the JOIDES. The publication also includes a list of participants aboard the JOIDES Resolution for Leg 157, as well as a list of SEDCO officials and ODP engineering and operations personnel. The publication also includes a list of ODP technical and logistics personnel, as well as a list of Ocean Drilling Program Publications Staff. The publication also includes a publisher's note on the use of abbreviations in ODP reference lists. The publication includes a table of contents and a list of abbreviations used in the volume. The publication includes a list of acknowledgments, and a list of references. The publication includes a list of the scientific achievements of the ODP, including new information on early seafloor spreading and how continents separate and the margins evolve. The publication also includes a list of the member organizations of the JOIDES, as well as the prime contractor and operating institution of the ODP. The publication includes a list of the ODP directors and administrators. The publication includes a list of the ODP logging operator, as well as a list of the participants aboard the JOIDES Resolution for Leg 157.
