Migration is a complex and multifaceted phenomenon that has significant implications for both sending and receiving countries. In the Atlantic basin, the movement of people across borders has been shaped by various factors such as economic opportunities, political instability, social networks, and historical ties. [This report] aims to explore the trends in African migration within the Atlantic basin, focusing on case studies of Nigerian migration to the United States, the United Kingdom, and South Africa as well as Moroccan migration to the European Union. It seeks to provide valuable insights into ongoing discourse on African migration by exploring case studies from diverse regions within the Atlantic basin, it highlights the interconnectedness of migration flows and their impact on individuals, communities, and societies on both sides of the Atlantic.
Long-distance migration of peoples have been a central if little understood factor in global integration. The essays in this collection contribute to a new history of world migrations, written by specialists of particular areas of the world. Collectively these essays point towards a shift from the regional migrations of individual seas and oceans of the early modern era toward nineteenth-century labor migrations that connected the Pacific and Indian to the Atlantic Oceans. Detailed case studies demonstrate the importance of human migration in the development, consolidation and critique of empire-building, theories of race, modern capitalism, and large-scale commercial agriculture and industry on every continent.
The Atlantic salmon is one of the most prized and exploited species worldwide, being at the centre of a massive sports fishing industry and increasingly as the major farmed species in many countries worldwide. Atlantic Salmon Ecology is a landmark publication, both scientifically important and visually attractive. Comprehensively covering all major aspects of the relationship of the Atlantic salmon with its environment, chapters include details of migration and dispersal, reproduction, habitat requirements, feeding, growth rates, competition, predation, parasitsm, population dynamics, effects of landscape use, hydro power development, climate change, and exploitation. The book closes with a summary and look at possible future research directions. Backed by the Norwegian Research Council and with editors and contributors widely known and respected, Atlantic Salmon Ecology is an essential purchase for all those working with this species, including fisheries scientists and managers, fish biologists, ecologists, physiologists, environmental biologists and aquatic scientists, fish and wildlife department personnel and regulatory bodies. Libraries in all universities and research establishments where these subjects are studied and taught should have copies of this important publication. Comprehensive and up-to-date coverage of Atlantic Salmon Atlantic Salmon is one of the world's most commercially important species Backed by the Norwegian Research Council Experienced editor and internationally respected contributors
The response of the tropical Atlantic Ocean to wind stress forcing on seasonal and interannual time scales is examined using an ocean data assimilation product from the Geophysical Fluid Dynamics Laboratory (GFDL), and an ocean general circulation model which incorporates a three dimensional flux correction technique to correct biases of the mean state of the ocean. On a seasonal time scale, we investigated the impact of the annual migration of the ITCZ on the exchange pathways of the northern tropical Atlantic. The results indicate that seasonal variation of the zonal slope of the thermal ridge along the boundary between the north equatorial countercurrent and north equatorial current in response to changes in the ITCZ controls, to a large extent, the amount of water participating in the equatorial circulation. These changes can be explained in terms of a simple dynamical model where local Ekman pumping dominates thermocline variation in the western part of the basin, and Rossby wave adjustment comes into play in the eastern basin. On an interannual time scale, we examined the upper heat budget of the equatorial Atlantic in order to identify the key mechanisms by which wind-driven ocean dynamics control SST variability during the onset and peak phases of the Atlantic zonal mode. It is found that, in contrast with Pacific ENSO, both Bjerknes and Ekman feedbacks act together to force the zonal mode, although their relative importance and dominance depend on season and location.
A comprehensive account of how abiotic and biotic interactions shape patterns of coastal marine biodiversity and ecosystem processes globally.
Written by a group of international experts in their field, this book is a review of Lagrangian observation, analysis and assimilation methods in physical and biological oceanography. This multidisciplinary text presents new results on nonlinear analysis of Lagrangian dynamics, the prediction of particle trajectories, and Lagrangian stochastic models. It includes historical information, up-to-date developments, and speculation on future developments in Lagrangian-based observations, analysis, and modeling of physical and biological systems. Containing contributions from experimentalists, theoreticians, and modelers in the fields of physical oceanography, marine biology, mathematics, and meteorology, this book will be of great interest to researchers and graduate students looking for both practical applications and information on the theory of transport and dispersion in physical systems, biological modeling, and data assimilation.
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.
