The heavily-revised Practical Handbook of Marine Science, Fourth Edition continues its tradition as a state-of-the-art reference that updates the field of marine science to meet the interdisciplinary research needs of physical oceanographers, marine biologists, marine chemists, and marine geologists. This edition adds an entirely new section devoted to Climate Change and Climate Change Effects. It also adds new sections on Estuaries, Beaches, Barrier Islands, Shellfish, Macroalgae, Food Chains, Food Webs, Trophic Dynamics, System Productivity, Physical-Chemical-Biological Alteration, and Coastal Resource Management. The Handbook assembles an extensive international collection of marine science data throughout, with approximately 1,000 tables and illustrations. It provides comprehensive coverage of anthropogenic impacts in estuarine and marine ecosystems from local, regional, and global perspectives. Maintaining its user-friendly, multi-sectional format, this comprehensive resource will also be of value to undergraduate and graduate students, research scientists, administrators, and other professionals who deal with the management of marine resources. Now published in full color, the new edition offers extensive illustrative and tabular reference material covering all the major disciplines related to the sea.

Concern about future supplies of fresh water to society, to meet the full range of human needs, now comes very high on the priority list of global societal issues. An overarching issue, which this book addresses, is whether global climate change is a dominant driver of change in the structure and function of all natural water-based ecosystems, or whether direct human population growth and accelerated consumption are playing an equal or greater role. This book divides the whole aquatic realm into 21 ecosystems, from those on land (both saline and fresh water) to those of the open and deep oceans. It draws on the understanding of leading ecologists to summarize the state and likely condition by the year 2025 of each of the ecosystems. Written for academic researchers and environmental professionals, the aim is to put the climate change debate into a broader context as a basis for conservation science and planning.

The Federated States of Micronesia’s National Strategy on Aquatic Animal Health 2021–2024, a broad and comprehensive strategy to build and enhance capacity for the management of national aquaculture biosecurity and aquatic animal health, was developed under FAO’s Project TCP/MIC/3603/C2: “National Aquatic Animal Health and Biosecurity Strategy”. The FSM’s NSAAH has taken into consideration a new initiative that FAO and partners have developed – the Progressive Management Pathway for Improving Aquaculture Biosecurity (PMP/AB). The application of the NSAAH has now expanded to fit as an important element of the PMP/AB.This initial strategy document outlines 15 major Programmes that will assist in developing a national approach to overall management of national aquaculture biosecurity and aquatic animal health. To complete this draft document, the Competent Authority (the Department of Resources and Development, R&D) should review the brief summaries of key projects suggested to be of immediate high priority to be accomplished under each of the 15 Programmes, modifying or adding to these as appropriate. The R&D will also need to develop an associated Implementation Plan for the National Strategy on Aquatic Animal Health (NSAAH) that identifies the activities that must be accomplished, the responsible sector(s) (government, private sector, and/or academia), the key staff, details of each project, the time-frame and an associated budget and source of funding (government, private sector, or other source). It is expected that progress toward completion of the various Projects will be reviewed on a regular basis and, beginning in 2023, the NSAAH and its Implementation Plan will be revised and renewed on a 5-year basis. At these intervals, and as national aquaculture development and aquatic biosecurity progresses through completion of Projects, new Programmes and Projects will be added. As an evolving and living document, the NSAAH will contain the national action plans for short-, medium- and long-term phased implementation based on national priorities.The 15 Programmes included in this NSAAH for 2021–2024 are: Programme 1: Policy, Legislation and Enforcement; Programme 2: Risk Analysis; Programme 3: National Aquatic Pathogen List; Programme 4: Border Inspection and Quarantine; Programme 5: Diagnostics; Programme 6: Farm-level Biosecurity and Health Management; Programme 7: Veterinary Drugs and Avoidance of Antimicrobial Resistance; Programme 8: Surveillance, Monitoring and Reporting; Programme 9: Communication and Information System; Programme 10: Emergency Preparedness and Contingency Planning; Programme 11: Research and Development; Programme 12: Institutional Structure (including Infrastructure); Programme 13: Human Resources and Institutional Capacity Development; Programme 14: Regional and International Cooperation; and Programme 15: Ecosystem Health.

This volume examines the deep sea ecosystem from a variety of perspectives. The initial chapters examine the deep-sea floor, the deep pelagic environment and the more specialised chemosynthetic environments of hydrothermal vents and cold seeps. These environments are examined from the perspective of the relationship of deep-sea animals to their physico-chemical environment.Later chapters examine the biogeography of the main deep oceans (Atlantic, Pacific and Indian) with particular attention to the downward flux of surface-derived organic matter and how this drives the processes within the deep-sea ecosystem. The peripheral deep seas including the polar seas and the marginal deep seas (inter alia the Mediterranean, Red, Caribbean and Okhotsk seas) are explored in the same context. The final chapters examine the processes occurring in the deep sea and include an analysis of why the deep sea has high species diversity, how the fauna respond to organic input and how species have adapted reproductive activity in the deep sea. The volume concludes with an analysis of the anthropogenic impact on the deep sea.
