Book Sea Level Rise for the Coasts of California Oregon and Washington

Download or read book Sea Level Rise for the Coasts of California Oregon and Washington written by National Research Council and published by National Academies Press. 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.

Book The Space Time Scales of Variability in Oceanic Thermal Structure Off the Central California Coast

Download or read book The Space Time Scales of Variability in Oceanic Thermal Structure Off the Central California Coast written by L. C. Breaker and published by . This book was released on 1983 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the active coastal upwelling regime off Pt. Sur, there was an equatorward surface jet 15 to 40km offshore, and a weaker poleward undercurrent near the continental slope. Based on tendency analyses of a set of quasi-synoptic hydrographic surveys, both upwelling and mixing were important in lowering sea-surface temperature (SST). The coastal bathymetry influenced the in situ property distributions around Pt. Sur, and the satellite-derived SST patterns. Based on the satellite data, the upwelling frontal boundary meandered with space and time scales of about 80km (alongshore) and 30 to 40 days, respectively. Over several months, the major upwelling frontal boundary gradually moves the order of 50km offshore. The major abrupt decreases in coastal SST (of order 3C) in certain years were attributed to the spring transition to coastal upwelling. The four E1 Nino episodes of the past 12 years were evident in coastal SST. E1 Nino events may initiate, and apparently strengthen, the spring transitions. Based on daily surface and subsurface temperature, correlation time scales ranged from several days (subsurface) to almost ten days (surface).

Book Geostrophic Circulation Off the Coast of Central California

Download or read book Geostrophic Circulation Off the Coast of Central California written by Robert Lee Brown and published by . This book was released on 1974 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seasonal variations in temperature, salinity, water masses and geostrophic currents at the surface and 200 m are discussed for the region off the Central California coast near Monterey. The results were obtained from data collected on six cruises covering a span of two years from 1970 to 1972. It is shown that the surface currents are subject to marked seasonal variability with the mean flow characterized by eddies and filaments. The currents at 200 m are similar to those found at the surface. The bottom topography influences the direction of flow inside the 1000 fathom curve. Seasonal variations in temperature and salinity generally conformed to Skogsberg's (1936) annual cycle composed of three distinct hydrographic seasons. Only subtle changes in water masses from season to season were noted. (Modified author abstract).

Book A Comparison of Oceanic Parameters During Upwelling Off the Central Coast of California

Download or read book A Comparison of Oceanic Parameters During Upwelling Off the Central Coast of California written by Arthur Bishop Shepard and published by . This book was released on 1970 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: An examination of the region between Monterey Bay and San Francisco Bay, California was conducted from 29 April to 5 May 1970 to study the effects of upwelling on the Central California, coastal region. Six parameters: temperature, phosphate, beam transmission for light, chlorophyll a, Coulter particle size distributions, and oxygen were observed at eighty-five stations from the surface to 100 m in the cruise area. The data gathered are presented in the form of horizontal contours and profiles which indicate: (1) Almost the entire surface layer was saturated with respect to oxygen. (2) There were four areas, at the northern and southern ends of Monterey Bay, off Point Montara, and west of the entrance to San Francisco Bay, which exhibited high values of chlorophyll a, oxygen, and particle count, for correspondingly low phosphate values and low beam transmission. (3) These productive areas are inshore, generally within 5-10 miles of the coast. (Author).

Book Variability in Coastal Upwelling Off Central and Northern California

Download or read book Variability in Coastal Upwelling Off Central and Northern California written by Marisol Garcia Reyes and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological productivity along the California coast is due to wind-driven upwelling, but fluctuations in productivity are mostly associated with ocean temperature - often both parameters are analyzed independently. This study analyzes the variability in coastal upwelling at different time scales and how wind forcing and ocean response impact biological productivity. For this, 29 years of wind and sea surface temperature (SST) from NOAA buoys are analyzed. Seasonality of alongshore wind and SST is divided in three seasons: Upwelling Season (April-June) with strong upwelling winds and large variability due to short wind reversals, and cold SST. Resulting weak stratification allows upwelling of nutrient-rich water; Relaxation Season (July-September) with weak winds and low variability. SST and stratification are high due to surface warming during long relaxation events limiting the amount of nutrients upwelled; Storm Season (December-February) with weak mean wind but large variability, and SST not related to upwelling. Latitudinal differences are due to topography, atmospheric boundary layer, and the gradient in solar heating. On synoptic time scales, response to upwelling wind events varies with Intensity (length and strength) and SST at the beginning of events. This initial temperature depends on time of year, climate state, and length of previous relaxation period, which influences stratification. On intra-annual time scales, wind is influenced by the pressure systems over the North Pacific and continent, and the El Nino-Southern Oscillation (ENSO). A trend of enhanced upwelling is observed, associated to the increase in greenhouse gases or to a multi-decadal trend in the Pacific Ocean temperature. SST variability is influenced by wind, interannual to multi-decadal variability in SST and sea-surface height of the North Pacific, and ENSO. A negative trend in SST is observed - associated to wind, but limited by the increase in global temperature. The effect on biological productivity is analyzed using the relationship between temperature and NO3 concentration. An Effective Upwelling index is developed to measure the capacity of wind to bring nutrients to the euphotic zone. It captures differences in biological productivity among seasons, and in interannual scales.

Book Sea Levels and Metered Currents Off Central California

Download or read book Sea Levels and Metered Currents Off Central California written by Donald A. Dreves and published by . This book was released on 1980 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea levels from two locations, the alongshore sea level gradient and direct measurement of currents by moored current meters are examined and discussed. The observations were made off the central California coast during the Davidson Current period 1978-9. Analysis for spectral variance of hourly and low pass filtered sea levels, alongshore sea level gradient and alongshore and cross shelf currents was performed. Comparison of spectral estimates of low pass filtered data indicate that current and sea level gradient energy distributions are in close agreement. This is interpreted to suggest that a relationship may exist between the observed currents and the longshore sea level gradient. In contrast, the low pass filtered sea level spectrum indicates energy concentrated at lower frequencies than was observed for currents. (Author).
