Tremendous advances in oceanographic observing and modeling systems over the last decade have led to unprecedented developments in the nature of information available to marine science. While improvements in observational technologies and networks have garnered much attention, remarkable developments in forecasting the ocean have received much less focus. Exploiting this new predictive skill to improve scientific understanding, generate advice and aid in the management of marine resources, is emerging as one of the new challenges of marine science. Translating predictions of the physical environment into biological outcomes, however, is not straightforward. Fisheries scientists, for example, have been trying to understand the links between physics and biology, and generate predictions of variables such as recruitment, for close to a century, with limited success. Nevertheless, spatial distributions and the timing of key events, which have received less focus, are often tightly linked to the physical environment and may have management-relevant applications. The first-such forecasts based on this skill are now starting to emerge. This Frontiers in Marine Science Research Topic provides a snapshot of the state-of-the-art in Marine Ecological Prediction. It covers the opportunities for developing such forecasts, technical approaches that could be employed, and examples where the technology is already being applied. This body of work therefore marks an important milestone on the route to developing this new and exciting field of marine science.

Fish in U.S. waters from Cape Hatteras to the Canadian border have moved away from their traditional, long-time habitats over the past four decades because of fundamental changes in the regional ecosystem. During the past 40 years, the ecosystem has experienced extensive fishing by domestic and foreign fleets, changes in ocean water temperatures due to climate change, and pressures from increasing human populations along the coast. This report highlights the need to understand natural and human-related changes in this region and to develop effective management and mitigation strategies. These changes have been linked to changes in the distribution and abundance of fish species in the region and their major sources of food. Illus.

The marine environment is one of our most precious yet fragile natural resources. It provides a wide range of essential goods and services, including food, regulation of climate and nutrient cycling, as well as a setting for transport, recreation and tourism. This environment is however extremely complex and very sensitive to development pressures and other forms of human influence. Planning and management of the sea are similarly complicated, reflecting intricate legal, institutional and ownerships patterns. This creates a situation where marine ecosystems are vulnerable to over-exploitation or neglect. The Ecosystem Approach to Marine Planning and Management describes how growing concern about the state of our seas is resulting in the development of new approaches to marine planning and management. For example, the United Nations Environment Programme has called for the widespread introduction of Marine Spatial Planning (MSP), and the European Union has recently been consulting on a new European Maritime Policy designed to stimulate economic growth but at the same time protect the resource base. Within the United Kingdom, the 2010 Marine Act draws upon the experience of town and country planning and brings into being a new system of Marine Spatial Planning. The authors show that a common feature of all these developments is an appreciation that more integrated forms of planning and management are required for our seas and that new arrangements must draw together understanding from natural science, social science and many other perspectives. Adopting such a trans-disciplinary and holistic (or 'ecosystems') approach, the book distils the expertise of these different disciplines and seeks to promote a broader understanding of the origins and practicalities of new approaches to marine planning and management.

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.

Climate change is anticipated to have long-term and pervasive effects on marine ecosystems, with cascading consequences to many ocean-reliant sectors. For the marine fisheries sector, these impacts can be further influenced by future socio-economic and political factors. Hence, raises the need for robust projections to capture the range of potential biological and economic risks and opportunities posed by climate change to marine fisheries. Here, we project the future changes in the relative abundance of eight commercially-important fish and crab species in the Pacific Arctic region under the different CMIP6 Shared Socioeconomic Pathways leading to contrasting future (2021-2100) scenarios of warming, sea ice concentration, and net primary productivity changes. Our results show differential patterns of change in the abundance and distribution across species and scenarios, highlighting potential winners and losers under future climate change. Specifically, under the extreme socioeconomic pathway (SSP585), Pacific cod and snow crab abundances are projected to increase and decrease in the region, respectively with concomitant zonal and meridional shifts in the centers of gravity. Importantly, projected changes in species abundance suggest that fishing at the same distance from the major port in the Bering Sea (i.e., Dutch harbor) could yield declining catches for highly valuable fisheries (e.g., Pacific cod and snow crab) under the SSP585 scenario. Declines in future catches of high value fisheries under SSP585 resulted to economic loss, despite an overall increase in the total potential catch dominated by low value fisheries. Albeit the results of this study should be taken with appropriate caution due to the simplistic model assumptions and projection uncertainties, these projected changes in abundances and shifting distributions could have relevant biological and economic repercussions on productivity of the Eastern Bering Sea ecosystem, commercial and subsistence fisheries, and effective management of transboundary resources.

Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.
