Concerned with the effects of marine plastic debris, Barker?s photographic work has reached worldwide audiences through international exhibitions, educational outreach, media reports and other means. Her aim is to expand public awareness of the environmental crisis by using aesthetically attractive visuals to communicate evolving scientific research.00This publication is introduced by Professor Richard Thompson OBE, a renowned marine scientist and Director of the University of Plymouth?s Marine Institute. His work has contributed to legislation on microbeads in cosmetics and other forms of plastic pollution.00Other texts include a foreword by Mandy Barker and an essay, Picturing Plastic Oceans, by Liz Wells, Professor in Photographic Culture at University of Plymouth. Barker also provides insight into the making of her images through an extensive survey of her personal process sketchbooks.
The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.
Recent decades have been marked by the decline or collapse of one fishery after another around the world, from swordfish in the North Atlantic to orange roughy in the South Pacific. While the effects of a collapse on local economies and fishing-dependent communities have generated much discussion, little attention has been paid to its impacts on the overall health of the ocean's ecosystems. In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean presents the first empirical assessment of the status of ecosystems in the North Atlantic ocean. Drawing on a wide range of studies including original research conducted for this volume, the authors analyze 14 large marine ecosystems to provide an indisputable picture of an ocean whose ecology has been dramatically altered, resulting in a phenomenon described by the authors as "fishing down the food web." The book: provides a snapshot of the past health of the North Atlantic and compares it to its present status presents a rigorous scientific assessment based on the key criteria of fisheries catches, biomass, and trophic level considers the factors that have led to the current situation describes the policy options available for halting the decline offers recommendations for restoring the North Atlantic An original and powerful series of maps and charts illustrate where the effects of overfishing are the most pronounced and highlight the interactions among various factors contributing to the overall decline of the North Atlantic's ecosystems. This is the first in a series of assessments by the world's leading marine scientists, entitled "The State of the World's Oceans." In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean is a landmark study, the first of its kind to make a comprehensive, ecosystem-based assessment of the North Atlantic Ocean, and will be essential reading for policymakers at the state, national, and international level concerned with fisheries management, as well for scientists, researchers, and activists concerned with marine issues or fishing and the fisheries industry.
A comprehensive introduction to ocean ecology and a new way of thinking about ocean life Marine ecology is more interdisciplinary, broader in scope, and more intimately linked to human activities than ever before. Ocean Ecology provides advanced undergraduates, graduate students, and practitioners with an integrated approach to marine ecology that reflects these new scientific realities, and prepares students for the challenges of studying and managing the ocean as a complex adaptive system. This authoritative and accessible textbook advances a framework based on interactions among four major features of marine ecosystems—geomorphology, the abiotic environment, biodiversity, and biogeochemistry—and shows how life is a driver of environmental conditions and dynamics. Ocean Ecology explains the ecological processes that link organismal to ecosystem scales and that shape the major types of ocean ecosystems, historically and in today's Anthropocene world. Provides an integrated new approach to understanding and managing the ocean Shows how biological diversity is the heart of functioning ecosystems Spans genes to earth systems, surface to seafloor, and estuary to ocean gyre Links species composition, trait distribution, and other ecological structures to the functioning of ecosystems Explains how fishing, fossil fuel combustion, industrial fertilizer use, and other human impacts are transforming the Anthropocene ocean An essential textbook for students and an invaluable resource for practitioners

CORRECTION: Regarding the book, The Battle for Paradise by Jeremy Evans, the following correction has been made on page 163 in paragraph three (3) to wit: “Weston once worked in concert with government officials in a pre-planned sting operation, complete with marked bills: Weston, whose role in the operation involved paying a bribe to the Golfito mayor for a concession and then documenting the bribe as a way to expose the mayor as a corrupt government official, was a former cocaine dealer, according to Dan, and someone who illegally acquired possession of his sawmill property.” Pavones, a town located on the southern tip of Costa Rica, is a haven for surfers, expatriates, and fishermen seeking a place to start over. Located on the Golfo Dulce (Sweet Gulf), a marine sanctuary and one of the few tropical fjords in the world, Pavones is home to a legendary surf break and a cottage fishing industry. In 2004 a multinational company received approval to install the world’s first yellowfin tuna farm near the mouth of the Golfo Dulce. The tuna farm as planned would pollute the area, endanger sea turtles, affect the existing fish population, and threaten the world-class wave. A lawsuit was filed just in time, and the project was successfully stalled. Thus began an unlikely alliance of local surfers, fishermen, and global environmental groups to save a wave and one of the most biodiverse places on the planet. In The Battle for Paradise, Jeremy Evans travels to Pavones to uncover the story of how this ragtag group stood up to a multinational company and how a shadowy figure from the town’s violent past became an unlikely hero. In this harrowing but ultimately inspiring story, Evans focuses in turn on a colorful cast of characters with an unyielding love for the ocean and surfing, a company’s unscrupulous efforts to expand profits, and a government that nearly sold out the perfect wave.
