Book Description
It is estimated that almost 10% of the worldwide marine biodiversity is encountered in the Mediterranean Sea which only represents 1% of oceans & seas. Whales, dolphins and other marine megafauna (seabirds, turtles, large fish) play a key role in maintaining the equilibrium of marine ecosystems and are an essential component of the natural heritage of Mediterranean and Black Sea countries. However, these species face a variety of significant threats: risk of collisions with maritime traffic, bycatch in fishing gears, habitat degradation, acoustic disturbance, chemical pollution and marine litter, climate change. The “ACCOBAMS Survey Initiative” (ASI) is a pilot program aimed at establishing an integrated and coordinated monitoring system for cetaceans throughout the entire ACCOBAMS area (Mediterranean and Black Seas). Conducted in coordination with riparian countries, it supports the implementation of European and regional policies, in particular the Marine Strategy Framework Directive (MSFD-EU) and the Ecosystem Approach process (Barcelona Convention UNEP/MAP). In summer 2018-2019, a synoptic line-transect sampling survey was carried out across the Black Sea, Mediterranean Sea and contiguous Atlantic area, combining visual methods (aerial surveys) and visual and passive acoustic monitoring (PAM) from vessels (focused primarily on deep diving species and areas where aerial surveys were not possible).

Book Description
The ocean is under increasing threat from the expansion of human activities. The combined impacts of these threats as well as the potential impacts of climate change and ocean acidification have placed thousands of species at risk of extinction, and have impaired the structure, function, productivity and resilience of marine ecosystems. Currently, some parts of the world's oceans are significantly impacted, yet are without any form of effective management. Only a small proportion of the oceans are within protected area systems. Globally, measures are being taken to increase protection and sustainable management, but application is uncoordinated and not always effective. In order to support effective policy action by countries and competent international and regional organizations, it is critical to build a sound understanding of the most ecologically and biologically important ocean areas that support healthy marine ecosystems so that the necessary steps to ensure the long-term function and resilience of these systems can be taken.

Book Description
The motivation for this strategic plan is to provide a national, unified approach for meeting science needs in partial support of the U.S. Marine Mammal Protection Act (MMPA) and the Endangered Species Act (ESA). The specific objective is to provide a framework for discussion of ship time with respect to, chiefly, cetacean science needs. The plan presented here is meant to aid in strategic planning for these science requirements in the context of other National Marine Fisheries Service (NMFS) priorities and National Oceanic and Atmospheric Administration’s (NOAA’s) Healthy Ocean Goal. In particular, it is hoped that a proactive and comprehensive strategic plan based on a predictable schedule and geographic area rotation will facilitate the continuation, and in some cases, the initial implementation of, research that will provide the majority of data required to meet NMFS’ cetacean-related mandates.
