Excerpt from Submerged Cultural Resources Study: Uss Arizona Memorial and Pearl Harbor National Historic LandmarkFrom the Arizona Memorial Museum Association, Gary Beito was very suppor tive of the survey work from its earliest stages. The clerks of the association bookstore were friendly to us despite our intrusive presence for weeks at a time over several years. The food and drinks donated by Concessionnaire Carol Lim are also ap preciated. Pacific Area Director Bryan Harry, senior park service official in the study area, kept a quiet, watchful eye on the project as it unfolded but was ready to lend his support whenever necessary. This project also required smooth coordination between two nps regional offices. Regional Directors of Western and South west Region (home office of scru) during the period the work took place were howardchapman and Stan Albright (western) and Bob Kerr and John Cook (southwest). Roger Kelly, regional ar cheologist for Western Region played an active role each year in ensuring that this interregional coordination and coopera tion held together. Chief archeologist of the National Park Service, Doug Scovill, has programmatic authority over the Sub merged Cultural Resources Unit and strongly supported the Pearl Harbor opera tion. Cal Cummings, senior service ar cheologist in Denver, paid an ou-site visit in 1986 and offered comparisons to work he was involved with on the uss monitor.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Forgotten Books uses state-of-the-art technology to digitally reconstruct the work, preserving the original format whilst repairing imperfections present in the aged copy. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in our edition. We do, however, repair the vast majority of imperfections successfully any imperfections that remain are intentionally left to preserve the state of such historical works. This 6th edition of Tools of Radio Astronomy, the most used introductory text in radio astronomy, has been revised to reflect the current state of this important branch of astronomy. This includes the use of satellites, low radio frequencies, the millimeter/sub-mm universe, the Cosmic Microwave Background and the increased importance of mm/sub-mm dust emission.Several derivations and presentations of technical aspects of radio astronomy and receivers, such as receiver noise, the Hertz dipole and beam forming have been updated, expanded, re-worked or complemented by alternative derivations. These reflect advances in technology.The wider bandwidths of the Jansky-VLA and long wave arrays such as LOFAR and mm/sub-mm arrays such as ALMA required an expansion of the discussion of interferometers and aperture synthesis. Developments in data reduction algorithms have been included.As a result of the large amount of data collected in the past 20 years, the discussion of solar system radio astronomy, dust emission, and radio supernovae has been revisited.The chapters on spectral line emission have been updated to cover measurements of the neutral hydrogen radiation from the early universe as well as measurements with new facilities. Similarly the discussion of molecules in interstellar space has been expanded to include the molecular and dust emission from protostars and very cold regions.Several worked examples have been added in the areas of fundamental physics, such as pulsars.Both students and practicing astronomers will appreciate this new up-to-date edition of Tools of Radio Astronomy. Astrophysics is often -with some justification - regarded as incomprehensible without the use of higher mathematics. Consequently, many amateur astronomers miss out on some of the most fascinating aspects of the subject. Astrophysics Is Easy! cuts through the difficult mathematics and explains the basics of astrophysics in accessible terms. Using nothing more than plain arithmetic and simple examples, the workings of the universe are outlined in a straightforward yet detailed and easy-to-grasp manner. The original edition of the book was written over eight years ago, and in that time, advances in observational astronomy have led to new and significant changes to the theories of astrophysics. The new theories will be reflected in both the new and expanded chapters. A unique aspect of this book is that, for each topic under discussion, an observing list is included so that observers can actually see for themselves the concepts presented -stars of the spectral sequence, nebulae, galaxies, even black holes. The observing list has been revised and brought up-to-date in the Second Edition. Thoroughly revised for its 2nd edition, this book presents state-of-the-art coverage of stellar physics, and interprets sophisticated current stellar models. A comprehensive view of the physics of the stellar interior and underlying processes and parameters. Comprehensive, authoritative coverage of interferometric techniques for radio astronomy In this Second Edition of Interferometry and Synthesis in Radio Astronomy, three leading figures in the development of large imaging arrays, including very-long-baseline interferometry (VLBI), describe and explain the technology that provides images of the universe with an angular resolution as fine as 1/20,000 of an arcsecond. This comprehensive volume begins with a historical review followed by detailed coverage of the theory of interferometry and synthesis imaging, analysis of interferometer response, geometrical relationships, polarimetry, antennas, and arrays. Discussion of the receiving system continues with analysis of the response to signals and noise, analog design requirements, and digital signal processing. The authors detail special requirements of VLBI including atomic frequency standards, broadband recording systems, and antennas in orbit. Further major topics include: * Calibration of data and synthesis of images* Image enhancement using nonlinear algorithms* Techniques for astrometry and geodesy* Propagation in the neutral atmosphere and ionized media* Radio interference* Related techniques: intensity interferometry, moon occultations, antenna holography, and optical interferometry Interferometry and Synthesis in Radio Astronomy, Second Edition is comprehensive in that it provides an excellent overview of most radio astronomical instrumentation and techniques. In Stars Above, Earth Below, Tyler Nordgren examines a range of astronomical topics and makes the connection between them and the landscapes, processes, and cultures which can be seen and experienced within specific U.S. National Parks. For each park and topic the story unfolds in three steps: what does the reader see for him - or herself? What is the scientific cause or explanation of what is seen? And finally, what is the big picture about ourselves, our world, and our Universe? The author takes us the length and breadth of the U.S., from the coast of Maine to the Yellowstone volcano, from the depths of the Grand Canyon to the heights of the Rocky Mountains, exploring the natural links between the features of the parks and those of our Universe. This advanced undergraduate text provides broad coverage of astronomy and astrophyscis with a strong emphasis on physics. It has an algebra and trigonometry prerequisite, but calculus is preferred.
