Book Description
Submarine canyons are some of the most prominent features of the world’s continental margins creating heterogeneity in the terrain, influencing local and global hydrodynamics and often creating hotspots of biodiversity, both on the seafloor and in the water column. Canyon morphology and location on the margin make them the main conduits between the shelf and the deep sea, focussing the transport of sediments, organic matter, nutrients, and increasingly pollutants and litter. The focus of this Research Topic is highlighting human connections to the deep sea. Previous studies have underlined the need for a better understanding of anthropogenic impacts on submarine canyons, and how they fast-track our human footprint to the deep sea. Besides a better assessment of the extent and nature of human activities in submarine canyons, it primarily requires a holistic understanding of submarine canyons as systems, governed by the interplay of geological, sedimentological, oceanographic and biological processes. The goal of this Research Topic, based on the recent INCISE2021 International Symposium on Submarine Canyons, aims to fill that gap by gathering the latest observations of human activities in submarine canyons, the latest insights in submarine canyon functioning, and the latest interpretations on how the two are influencing each other.

Book Description
This book offers a comprehensive account of the status and dynamics of people participating in the small-scale fisheries (SSF) of Europe. It covers the situation of SSF in 25 coastal countries, thereby providing a portrait of almost every coastal country on the continent and analyzing the recent evolution of the sector. Small-scale fisheries are argued to be extremely important in Europe, as they provide employment and welfare, while increasing food sovereignty and maintaining communities in coastal areas. The recent worldwide focus on SSF derives from their environmental sustainability, which distinguishes many of their activities from those of large-scale fisheries. This book analyses the diversity of SSF and shows how fishing communities have sometimes developed successful governing models, demonstrating social and economic resilience. While the book emphasizes the strengths of SSF and the synergies that occur with other marine sectors, it also presents cases of failure, in which collective action and policy have actually contributed to a weakening of the sector. In this context, the book shows how governmental policies toward SSF vary considerably from country to country, in a way that is not entirely consistent with European policies.

Book Description
Bycatch – a term widely used to refer to part of the catch unintentionally caught during a fishing operation, in addition to target species, and consisting of the discards and incidental catch of vulnerable species – is considered one of the most important threats to the profitability and sustainability of fisheries, as well as to the conservation of the marine environment and ecosystems. Understanding the bycatch issue and adopting effective measures in order to reduce bycatch rates are essential steps towards minimizing the impacts on vulnerable species and ensuring both a sustainable fisheries sector and healthy seas. In the Mediterranean and the Black Sea, the incidental catch of vulnerable species – namely seabirds, sea turtles, elasmobranchs, marine mammals and macrobenthic invertebrates – represents one of several challenges for the industrial, semi-industrial and small-scale fisheries that coexist in the region, as well as for the diverse and sensitive ecosystems impacted. Typically, data on this issue have been collected in an opportunistic manner and in ways that make comparisons difficult. The annual absolute values of incidental catch of vulnerable species are not available: studies cover only a small portion of the total fishing activity and often present important knowledge gaps for many types of fishing gear, countries and/or subregions, as well as on temporal scales, for example, to establish reliable baselines. The result is that little is known of the scope of the problem, despite incidental catch being a significant pressure on the populations of vulnerable species, as well as a concern for fishers.This regional review is an attempt to compile, in one single document, all available data and historical records on the incidental catch of vulnerable species in the Mediterranean and Black Sea fisheries, obtained from existing literature, databases and other grey sources, and collated in a standardized and comparable way. The main objective is to provide comprehensive baseline information, earmark the main data gaps, as well as identify the most impacting types of fishing gear by taxonomic group. This work is a reminder of the importance of standardized data collection and the need to have baseline information in order to support decision-making in the identification of appropriate bycatch mitigation techniques, thus enabling analysis of their effectiveness and comparison over time and space, as well as facilitating the implementation of relevant conservation and/or management measures at the national, subregional and regional levels.

Book Description
The Law of the Seabed reviews the most pressing legal questions raised by the use and protection of natural resources on and underneath the world’s seabeds. While barely accessible, the seabed plays a major role in the Earth’s ecological balance. It is both a medium and a resource, and is central to the blue economy. New uses and new knowledge about seabed ecosystems, and the risks of disputes due to competing interests, urge reflection on which regulatory approaches to pursue. The regulation of ocean activities is essentially sector-based, and the book puts in parallel the international and national regimes for seabed mining, oil and gas, energy generation, bottom fisheries, marine genetic resources, carbon sequestration and maritime security operations, both within and beyond the national jurisdiction. The book contains seven parts respectively addressing the definition of the seabed from a multidisciplinary perspective, the principles of jurisdiction delimitation under the United Nations Convention on the Law of the Sea (UNCLOS), the regimes for use of non-living, living and marine biodiversity resources, the role of state and non-state actors, the laying and removal of installations, the principles for sustainable and equitable use (common heritage of mankind, precaution, benefit sharing), and management tools to ensure coexistence between activities as well as the protection of the marine environment.

Book Description
The Alboran Sea represents a regional Mediterranean space where North and South worlds merges, creating a geopolitical region where marine resources and maritime activities should be managed from a national and international perspectives. It is widely known, that currently the planet is suffering a global change, and it is also affecting the Alboran Sea, its ecosystems and populations. An important first step to update a paramount vision on this region is to understand the climatic, geologic and oceanographic, including biochemical cycles, process which shapes the rich geodiversity, biodiversity, the productivity, and the sustainable use of the marine resources from Alboran Sea. The fisheries management system should take into account marine environmental variability to achieve biological sustainability of marine resources. Well-funded policy-makers’ decisions require a sound science based knowledge of the interaction between the marine environment and commercial stocks. This is because the role of marine environment in the evolution of fish stocks is sometimes even more important than the one played by fishers in the commercial exploitation of them. Finally, we should analyze the different aspects of political context that could affect the management of the resources from Alboran Sea in the context of climate change. This book reviews different aspects of the Alboran Sea to help understand the current situation from the original Tethis Ocean. The book is divided into four blocks: (i) Oceanographic, geological and ecological context (chapters 2 to 7), (ii) biodiversity and ecosystems distribution (chapters 8 to 12), (iii) fisheries resources and aquaculture (chapters 13 to 20), and (iv) conservation, management and marine polices (chapters 21 to 25).

Book Description
Corals comprise a wide variety of colonial marine invertebrates belonging to the Phylum Cnidaria. Their polyps form the most colorful, complete, and diverse communities on the Earth resembling underwater cities, commonly called coral reefs, which host a wide variety of invertebrates and fish species. They are highly productive ecosystems, contribute to the health of the biosphere, and offer a good number of economic and ecological services to coastal populations and to many people around the world. However, due to a diverse number of natural and anthropogenic stressors, corals have shown a severe decline over the past few decades. Being aware of the importance and relevance of the facts described, the book "Corals in a Changing World" offers new scientific information regarding the actual status and, in some cases, the resilience state of coral reef systems. Timely information is critical for managers and decision makers to implement sustainable management measures according to the ecological condition of coral reefs. In addition, the book also discusses the use of well-maintained coral microcosms to provide a good basis for performing experiments with natural fluctuations and to present studies dedicated to the coral diversity characterization and to their importance as a source of important biological compounds, which could be converted into industrial products.
