This book was released on 2013 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic Zone Monitoring Program (AZMP) was implemented in 1998 with the aim of increasing Fisheries and Oceans Canada's (DFO's) capacity to understand, describe, and forecast the state of the marine ecosystem, and quantifying the changes in ocean physical, chemical, and biological properties. A critical element in the observational program of AZMP is an annual assessment of the distribution and variability of nutrients and the plankton they support. Herein, the optical, chemical, and biological oceanographic (lower trophic levels) conditions observed in 2012 in the Maritimes Region, including the Georges Bank/Gulf of Maine/Bay of Fundy system and the Scotian Shelf are reviewed. In the context of record warm conditions in 2012, this report focused on evaluating changes in phytoplankton and zooplankton annual production cycles and community composition.--Document.

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 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.

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.

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.

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.
