    Get PDF
    This dissertation is a study of the widespread utilization of satellite technology in the maritime world, with particular reference to the applications and implications of communication, navigation and remote sensing satellites to shipping and other maritime related fields. A brief look is taken at the general background of satellite technology, including the growth and development and basic techniques as well as categorization of applications. This is followed by a more detailed view of the three different areas of the applications of satellite technology, namely maritime communications, marine navigation and maritime meteorology and oceanography. The two well-known satellite-based systems, the INMARSAT System and the Global Positioning System, are both widely used by the maritime community and thus emphasized in this study. Apart from a brief description of those two systems, their applications are examined, their impact on the marine industry is discussed and their future development is investigated in order to obtain an appreciation of their role in the present maritime world. The applications of remote sensing satellites in marine meteorology and oceanography are also discussed. In addition to the above, the impact of the increasing use of satellite technology on maritime education and training is investigated. The concluding chapter is a summary of the main points discussed in the core chapters, which reflect the author’s viewpoin

    Geodetic techniques in detecting and monitoring geodynamic phenomena are reviewed. Specific areas covered include: rotation of the earth and polar motion; tectonic plate movements and crustal deformations (space techniques); horizontal crustal movements (terrestrial techniques); vertical crustal movements (terrestrial techniques); gravity field, geoid, and ocean surface by space techniques; surface gravity and new techniques for the geophysical interpretation of gravity and geoid undulation; and earth tides and geodesy

    Submarine Commander: A Story of World War II and Korea

    Get PDF
    A fascinating personal memoir of underwater combat in World War II, told by a man who played a major role in those dangerous operations. Frank and beautifully written, Submarine Commander’s breezy style and irrepressible humor place it in a class by itself. This book will be of lasting value as a submarine history by an expert and as an enduring military and political analysis. In early 1943 the submarine USS Scorpion, with Paul R. Schratz as torpedo officer, slipped into the shallow waters east of Tokyo, laid a minefield, and made successful torpedo attacks on merchant shipping. Schratz participated in many more patrols in heavily mined Japanese waters as executive officer of the Sterlet and the Atule. At war’s end he participated in the Japanese surrender, aided the release of American POWs, and had a key role in the disarming of enemy suicide submarines. He then took command of the revolutionary new Japanese submarine I-203 and returned it to Pearl Harbor. But this was far from the end of Schratz’s submarine career. In 1949 he commissioned the ultramodern USS Pickerel, the most deadly submarine then afloat, and set a world’s record in a 21-day, 5,200-mile submerged passage from Hong Kong to Honolulu. With the outbreak of the Korean War, the Pickerel was immediately sent to Korea to participate in secret intelligence operations only recently declassified and never before revealed in print. Schratz’s broad military experience makes this a far from ordinary memoir. The U.S. Navy\u27s most innovative, non-conforming, daring skipper tells in intimate detail a gripping and exciting story—unashamed in sorrow, proud in record-setting accomplishment, rich in humor. Great! -- Adm. I.J. Galantin, USN (Ret.), author of Take Her Deep An authoritative, useful, and interesting view of Pacific Ocean submarine operations. -- American Historical Review Provides the layperson with an interesting, exciting, and ultimately satisfying account of submarine service, both during WWII and the Korean War. -- Choice An extraordinary story . . . Schratz is a superb observer! -- Friday Review of Defense Literature An ebullient, consistently engrossing memoir of submarine service in WWII\u27s Pacific theater and during the Korean conflict. -- Kirkus Reviews An action-filled account of the wartime operations of the Navy submarine fleet. -- McCormick (SC) Messenger Serves as a moving testimonial to the many brave men with whom he served. -- Northern Mariner A commanding and well told tale . . . . Schratz succeeds in making wartime submarining come alive for nonsubmariners. -- Shipmate Fascinating . . . A delight to read not only because it is well written but because it is so very real seen through the eyes of a completely involved observer. -- Submarine Review Schratz’s description of life aboard a submarine is one of the single best accounts of the \u27Silent Service\u27 during World War II and the Korean War….The book is highly recommended. -- Leo J. Daugherty III -- World War Quarterlyhttps://uknowledge.uky.edu/upk_military_history/1035/thumbnail.jp

    The use of high resolution geophysics for the investigation of submerged palaeo-glaciomarine environments

    A multi-disciplinary, high resolution, geophysical investigation of a Scottish Sea loch has facilitated both the reconstruction of a detailed late Quaternary para-stratigraphic model and the critical assessment of the acquisition and analytical methodologies most appropriate for the study of submerged palaeo-glaciomarine environments. Loch Ainort, situated on the eastern coast of the Isle of Skye, has been surveyed using a 192 kHz echosounder, a 400 kHz side scan sonar and a 3.5 kHz sub-bottom profiler. Lithological calibration was provided by the analysis of both in situ core data and extant terrestrial data sets. It is proposed that for the effective reconstruction of these and any other nearshore palaeo-environments a multi-disciplinary geophysical approach is essential. The critical control on success is the adherence, during interpretation, to a single unifying seismo-analytical framework. The seismo-stratigraphical analysis technique has been adapted for high- resolution work in order to provide this rigid framework. Objective descriptive analysis of the seismic traces provides a "seismic para-stratigraphy" which when combined with lithological data is used to construct a "composite para-stratigraphy". This is a process based, litho-stratigraphic interpretation that, by virtue of the detailed spatial extent afforded it by geophysical data, can be placed in a wider environmental context. The composite para-stratigraphy for the Loch Ainort basin is dominated by Loch Lomond Stadial glacial activity. Terminal and readvance limits are identified at several localities within the basin. Variable morphological styles of the glacial sequences show that deglaciation occurred in two distinct, climatically controlled, phases. The first marked by a fluctuating ice margin and the second by uninterrupted retreat and in situ ice stagnation. Sub-aerially induced debris flows occur during the initial paraglacial phase but stabilisation of exposed slopes restricts this input and rapid sedimentation of fines from sediment-rich meltwaters becomes dominant. Modern fjordic sedimentation develops after the disappearance of glacier ice

    Te Waka! Life histories of two contemporary Polynesian voyaging canoes

    Get PDF
    This thesis concerns the life-histories of the two contemporary Polynesian voyaging canoes from Aotearoa New Zealand. It documents the background, construction and voyages of Hawaiki Nui (1979- 1986) built by Matahi Whakataka-Brightwell and Te Aurere (1992 - 1998) built by Hekenukumai Puhipi Busby. It also highlights the historical and cultural significance of waka for Maori and other indigenous Pacific peoples. Based on my field work as a participant in Maori voyaging between 1996 and 1998, I argue that this revival of waka voyaging reaffirms the cultural identities of contemporary Maori and other Polynesians. The case studies of Hawaiki Nui and Te Aurere confirm the ongoing significance of waka not only in Aotearoa New Zealand, but Pacific-wide. Contemporary Polynesian waka voyaging is historically significant as it revives unique Polynesian skills, such as traditional waka-building, navigation and sailing techniques. It is also culturally significant, as it reinforces central Maori (and Polynesian) cultural concepts, such as whakapapa (genealogy ties) and whanaungatanga (sense of belonging). At a time when Maori (as well as other indigenous Pacific peoples) are constantly negotiating and redefining their cultural boundaries within their respective socio-political contexts, Polynesian voyaging waka are reappearing as a strong symbol of Pacific Islanders' cultural identities. As a symbol of a shared seafaring past they create timeless platforms for Maori and other Polynesians to negotiate the boundaries of their cultures
