This book was released on 1984 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea surface temperature (SST) since March 1, 1971 at Granite Canyon, just north of Pt. Sur, California, are examined for interannual variability. Each of four El Nino episodes occurring over the past 13 years can be easily detected in the raw data. Annual mean temperatures are significantly higher during the El Nino years. The 1982-83 El Nino episode was more intense than the previous episodes; temperatures were as much as 5C above normal during the episode and it lasted about 20 months. Major abrupt decreases in SST were frequently observed during the spring. These events are identified as the spring transition to coastal upwelling and appear to be most intense following El Nino episodes. Empirical Orthogonal Function analysis of the data indicates that maximum variability in SST's occurs between October and February and that it coincides with the four El Nino episodes occurring over the past 13 years.

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.

This book was released on 1985 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous studies of the tropical troposphere indicate the presence of a 40 to 50 day oscillation in zonal winds. Spectral analysis of sea surface temperature reveals an increase in variance between 40 and 50 days along the California coast as far south as Santa Barbara (34.4N) and at least as far north as Pt. Arena (39N). Increases in the amplitude of this oscillation at 36N generally coincide with local El Nino warming episodes. It is suggested that the 40 to 50 day oscillation in sea surface temperature off central California may be related to the 40 to 50 day oscillation in the tropical troposphere through atmospheric teleconnections between the tropics and mid-latitudes.

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 excerpt: "The warm and cold events observed in the currents are associated with distinct atmospheric circulation patterns. Thus, it is suggested that changes in the atmospheric circulation on interannual timescales induce anomalies in the air-sea heat exchange, which have been found to be partly responsible for the variability in SST of the Brazil and Malvinas Currents." --

Book excerpt: The IPCC Fifth Assessment Report (AR5) highlighted that conditions within Earth’s ocean are changing more rapidly than any of the time during the past 65 million years, and as a consequence, major changes are occurring in natural and human systems. While this major report as enhanced our understanding of the complexity of ocean issues, we propose this research topic as an opportunity to expand discussion on past, present and future changes across oceans regions.

This book was released on 2023-12-29 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eastern boundary upwelling systems (EBUS) have historically received attention from the scientific community due to their impact on the economic development of these highly productive systems. Remote sensing, numerical modeling, and in situ observations have increased their spatial and temporal resolutions during the last 40 years in their strategy to provide reliable products about the actual state of the ocean. The assembly of several data sources currently constitutes an opportunity to increase our knowledge about the present and future state of the relatively narrow and highly variable EBUS. The primary forcing mechanism in the upwelling regions is the wind stress in areas close to the coast. Long-term trends in wind intensity in upwelling areas present considerable uncertainties as the different wind databases produce divergent results. On the other hand, although the effect of climate change in the interior ocean is increasing temperatures in upwelling areas, the long-term trends seem to be in the opposite direction. Hence, assessing the long-term impact of the environmental conditions on upwelling development represents a major challenge for the scientific community. This special issue aims to discuss the state-of-the-art understanding of dynamical processes governing the ocean at the eastern boundary upwelling systems in a changing ocean.
