Download or read book Satellite Derived Global Ocean Product Validation Evaluation written by SeungHyun Son and published by MDPI. This book was released on 2020-12-11 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean satellite remote sensing plays important roles in the observations of physical, biological and biogeochemical features in inland, coastal, and global ocean waters, with high temporal and spatial resolution. The satellite-measured ocean products are used for near-real-time ocean monitoring and climate data records to understand short-/long-term variabilities in marine environments and ecosystems as well as for decision making tools to manage social, economic, and environmental benefits. Validation/evaluation including a combination of field measurements and inter-satellite comparison is an essential step in providing more accurate satellite-derived ocean products. In this Special Issue, 14 papers have been published and include research on validation/evaluation, retrieval algorithms of ocean geophysical and biogeochemical parameters, and application of the satellite ocean products in the regional and global ocean. Subjects treated include: Sea Surface Temperature; Sea Ice Surface Temperature from VIIRS thermal infrared sensor; Sea Ice Detection from Spectroradiometer; Sea Surface Winds from HY-2A Scatterometer and GNSS—Reflectometry; Wave Height from Sentinel-3A SAR; Retrievals of Sea Surface Salinity, Chlorophyll-a, Particulate Organic Carbon, Particulate Backscattering, Marine Fishery resource, and Submesoscale Eddies from multiple Ocean Colour sensors.

Download or read book Sea Change written by Ussif Rashid Sumaila and published by UBC Press. This book was released on 2024-04-01 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: As climate change, resource overexploitation, and pollution leave ever more visible marks, ocean ecosystems, economies, and people are all affected. With coasts on the Atlantic, Pacific, and Arctic, Canada faces a formidable challenge in building resilient, sustainable oceans and supporting the communities that rely on them. Sea Change reports on the OceanCanada Partnership, a multidisciplinary project to take stock of what we know about Canada’s oceans, construct possible scenarios for coastal regions, and create a national dialogue and vision. Three themes emerge from this impressive synthesis of social, cultural, economic, and environmental research: ocean change, access to ocean resources, and ocean governance. Indigenous and non-Indigenous scholars and practitioners focus on finding solutions to rapid environmental and social transformation, outlining the implications for legislation and offering policy recommendations. Increasingly, civil society will have to advocate for oceans, and Sea Change will empower the voices of those who take up that task.

Download or read book Real time Coastal Observing Systems for Marine Ecosystem Dynamics and Harmful Algal Blooms written by Babin, Marcel and published by UNESCO. This book was released on 2008-06-05 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.

Available in PDF, EPUB and Kindle. Book excerpt: Our longterm goal is to contribute to a fundamental understanding of the sources of biological, physical and optical variability in coastal ocean systems. Particular focus is on applications useful for studying important ecological processes and the links between phytoplankton properties and physical processes in coastal regions. The overall objective of this project is to improve understanding of the Gulf of Maine and Georges Bank system through characterization and modeling of optical properties in the context of physical and biological processes. We wish to describe the processes controlling space/time variability in the various constituents (CDOM, phytoplankton, sediment, detrital particles) that determine the optical properties of this region. As planned, our effort to date has been concentrated on processing and quality control for optical and hydrographic data collected during 5 cruises during 1997-1999. We have also made progress towards compiling an accessible database that includes our observations plus those collected by several other investigators working in the Gulf of Maine region. The compiled database is now being used to generate empirically driven parameterizations of optical variability for the Gulf of Maine region, which will in turn be used to construct an optical submodel (to later be coupled with biological and physical models). Our preliminary efforts to characterize optical variability present in the Gulf of Maine at different times of year have documented that some properties must be considered seasonally variable, while others seem more temporally stable. These observations will be quantitatively incorporated into the optical model we are constructing. Ultimately, we expect that integrating models of optical properties into our physically realistic ecosystem simulations will contribute to better understanding of the processes contributing to optical variability in coastal waters.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report investigates hydrographic changes on the Scotian Shelf and in the Gulf of Maine using 23 CMIP6 earth system models and two future scenarios (SSP245 and SSP370). For each model we first evaluate performance using HadISSTI data and ship-based measurements of bottom temperature. Next, we evaluated seasonality of SST based on forecasts from each CMIP6 model under both climate scenarios. Overall trends of the SST, SSS, SSH, BT and BS for the 2020-2049 period are investigated. In addition, changes of the aforementioned quantities, relative to a historical 1995-2014 period, are calculated for two future periods, 2030-2049 and 2040-2049"--Abstract, page v.

Download or read book Assessing the Requirements for Sustained Ocean Color Research and Operations written by National Research Council and published by National Academies Press. This book was released on 2011-12-15 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean is a fundamental component of the earth's biosphere. It covers roughly 70 percent of Earth's surface and plays a pivotal role in the cycling of life's building blocks, such as nitrogen, carbon, oxygen, and sulfur. The ocean also contributes to regulating the climate system. Most of the primary producers in the ocean comprise of microscopic plants and some bacteria; and these photosynthetic organisms (phytoplankton) form the base of the ocean's food web. Monitoring the health of the ocean and its productivity is critical to understanding and managing the ocean's essential functions and living resources. Because the ocean is so vast and difficult for humans to explore, satellite remote sensing of ocean color is currently the only way to observe and monitor the biological state of the surface ocean globally on time scales of days to decades. Ocean color measurements reveal a wealth of ecologically important characteristics including: chlorophyll concentration, the rate of phytoplankton photosynthesis, sediment transport, dispersion of pollutants, and responses of oceanic biota to long-term climate changes. Continuity of satellite ocean color data and associated climate research products are presently at significant risk for the U.S. ocean color community. Assessing Requirements for Sustained Ocean Color Research and Operations aims to identify the ocean color data needs for a broad range of end users, develop a consensus for the minimum requirements, and outline options to meet these needs on a sustained basis. The report assesses lessons learned in global ocean color remote sensing from the SeaWiFS/MODIS era to guide planning for acquisition of future global ocean color radiance data to support U.S. research and operational needs.

This book was released on 1995 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents and analyzes water temperature and salinity data collected during 11 mesopelagic resource inventory cruises in the continental slope region between 55 and 65 degrees west longitude. The data analysis results define water mass boundary positions in the upper 450 meters during the period of each cruise. Charts of surface boundary conditions based on satellite infrared imagery aid in interpreting the cruise data, and small numbers of bathythermograph casts to 1830 meters and conductivity-temperature-depth recorder casts to 1000 meters provide data for deeper waters. The report also describes the variation of temperature and salinity over time at a fixed location (41 degrees north, 61 degrees 30 minutes west) based on three occupations for periods of 1.5 to 3.5 days.

Download or read book Oceanography from Space written by Vittorio Barale and published by Springer Science & Business Media. This book was released on 2010-04-26 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: To all those sailors / Who dreamed before us / Of another way to sail the oceans. The dedication of this Volume is meant to recall, and honour, the bold pioneers of ocean exploration, ancient as well as modern. As a marine scientist, dealing with the oceans through the complex tools, ?lters and mechanisms of contemporary research, I have always wondered what it was like, in centuries past, to look at that vast ho- zon with the naked eye, not knowing what was ahead, and yet to sail on. I have tried to imagine what ancient sailors felt, when “the unknown swirls around and engulfs the mind”, as a forgotten author simply described the brave, perhaps reckless, act of facing such a hostile, menacing and yet fascinating adventure. Innovation has always been the key element, I think, for their success: another way, a better way, a more effective, safer and worthier way was the proper answer to the challenge. The map of our world has been changed time and again, from the geographical as well as the social, economic and scienti?c points of view, by the new discoveries of those sailors. One of the positive qualities of human beings is without doubt the inborn desire to expand their horizons, to see what lies beyond, to learn and understand.
