Book excerpt: This study is a part of the on-going effort aimed at improved determinations of the earth's gravity field through the adjustment of satellite altimeter data in the short-arc mode. Until recently the key role in such adjustments has been played by GEOS-3 altimeter data. However, SEASAT altimetry is envisioned as providing a more accurate means for addressing this task. In view of the improved quality of altimeter data and of the corresponding more stringent requirements for the data reduction, several improvements in the existing altimetry model have been designed and are described herein. For example, the criteria have been established specifying the maximum and the mimimum allowable lengths of SEASAT arcs. An important improvement in the economy has been achieved through a reduction in the number of spherical-harmonic potential coefficients entering the orbital integrator, without a noticeable compromise in the excellent quality of the SEASAT observational system.

Available in PDF, EPUB and Kindle. Book excerpt: In the recent past, SEASAT altimeter data together with global geoidal parameters and sets of state vectors parameters have been adjusted at AFGL through the short-arc algorithm using NSWC precise ephemeris. The excellent quality of the data system, including the altimeter measurements, the ephemeris, the input geoidal parameters, etc., has been confirmed by the finding that the empirical variance for geoid undulations is significantly lower than the theoretical variance. The altimeter residuals from this adjustment have served in regional modeling of short-wavelength geoidal features, as well as in studying geophysical phenomena such as ocean bottom topography. Since the geoid has been assumed to coincide with the ocean surface sensored by the altimeter, the sea-surface effects have been ignored in this adjustment. Due to increasing geophysical interest in a realistic representation of the open ocean tide, the latest development of the short-arc satellite altimetry model allows for the inclusion of the most important tidal constituents. In particular, an adjustment algorithm has been designed in which four long-period constituents, three diurnal constituents and four semidiurnal constituents may be subject to adjustment within the overall adjustment of SEASAT altimetric observations.

This book was released on 2012-12-06 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tide gauges show that global sea level has risen about 7 inches during the 20th century, and recent satellite data show that the rate of sea-level rise is accelerating. As Earth warms, sea levels are rising mainly because ocean water expands as it warms; and water from melting glaciers and ice sheets is flowing into the ocean. Sea-level rise poses enormous risks to the valuable infrastructure, development, and wetlands that line much of the 1,600 mile shoreline of California, Oregon, and Washington. As those states seek to incorporate projections of sea-level rise into coastal planning, they asked the National Research Council to make independent projections of sea-level rise along their coasts for the years 2030, 2050, and 2100, taking into account regional factors that affect sea level. Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future explains that sea level along the U.S. west coast is affected by a number of factors. These include: climate patterns such as the El Niño, effects from the melting of modern and ancient ice sheets, and geologic processes, such as plate tectonics. Regional projections for California, Oregon, and Washington show a sharp distinction at Cape Mendocino in northern California. South of that point, sea-level rise is expected to be very close to global projections. However, projections are lower north of Cape Mendocino because the land is being pushed upward as the ocean plate moves under the continental plate along the Cascadia Subduction Zone. However, an earthquake magnitude 8 or larger, which occurs in the region every few hundred to 1,000 years, would cause the land to drop and sea level to suddenly rise.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 69. The measurement of sea level is of fundamental importance to a wide range of research in climatology, oceanography, geology and geodesy. This volume attempts to cover many aspects of the field. The volume opens with a description by Bolduc and Murty of one of the products stemming from the development of tide gauge networks in the northern and tropical Atlantic. This work is relevant to the growth of the Global Sea Level Observing System (GLOSS), the main goal of which is to provide the world with an efficient, coherent sea level monitoring system for océanographie and climatological research. The subsequent four papers present results from the analysis of existing tide gauge data, including those datasets available from the Permanent Service for Mean Sea Level and the TOGA Sea Level Center. Two of the four, by Wroblewski and by Pasaric and Orlic, are concerned with European sea level changes, while Yu Jiye et al. discuss inter-annual changes in the Pacific, and Wang Baocan et al. describe variability in the Changjiang estuary in China. The papers by El-Abd and Awad, on Red Sea levels, are the only contributions to the volume from the large research community of geologists concerned with sea level changes.

Available in PDF, EPUB and Kindle. Book excerpt: Tides in the deep ocean can be determined directly from satellite altimetry, completely independent of assumptions about earth tides, bottom topography and coastal geometry and thus free of the uncertainties which plague numerical tide models. Existing tide models differ by 1 meter or more in the value of sea surface height in the deep ocean at a given place and time. This uncertainty is a formidable obstacle to determination of a precise marine geoids from satellite altimetry. By harmonic analysis of the temporal changes in altimeter measurements at satellite subtrack crossover points, it is possible to solve for the amplitude and phase of harmonic tidal components. However, care must be exercised in the removal of satellite orbit errors, and in the selection of crossovers for sufficient observability of the phase angle of the harmonic tidal component. Preliminary tidal solutions in the Gulf of Alaska using the relatively sparse GEOS-3 altimeter data distribution show generally good agreement (20 cm in amplitude and 25 degrees in phase) with deep ocean bottom pressure gauge measurements and establish the feasibility of this technique. SEASAT altimeter data yields a much greater density of crossovers (400 plus per 1/2 deg by 1/2 deg area), making possible much better separation of individual harmonic components within the semi-diurnal and diurnal families.

Available in PDF, EPUB and Kindle. Book excerpt: Flooding of coastal communities is one of the major causes of environmental disasters world-wide. This textbook explains at a basic level, how sea levels are affected by astronomical tides, by weather effects that generate extreme flooding events, and over the longer term by ocean circulation and climate trends. It also indicates how sea level changes are related to changing risks, coastal dynamics, geology and biology; and outlines some of the economic and legal implications. Based on courses taught by the author in the UK and the USA, this book is aimed at undergraduate students at all levels, with the text developed in such a way that non-basic mathematics is confined to Appendices and a web site (http://publishing.cambridge.org/resources/0521532183/). Changing Sea Levels will also interest and inform professionals in many fields including hydrography, coastal engineering, geology, biology and also coastal planning and economics.
