Y a-t-il eu en France deux marines distinctes, celle du Ponant et celle du Levant ? Les anecdotes recueillies dans les mémoires d'officiers de marine permettent de répondre positivement à cette question. De forts particularismes ont bien existé jusqu'à la fin de l'Ancien Régime. Ils se sont progressivement atténués tout au long des siècles suivants pour n'en laisser de nos jours que quelques traces. Mais il serait très hasardeux de prétendre porter un jugement de valeur sur les qualités respectives des marins bretons et provençaux. L'histoire maritime montre que dans ces mondes pourtant bien distincts la gloire et les faiblesses furent assez également partagées.

Nonindigenous species (NIS) are those that have been intentionally or unintentionally introduced outside of their native range as a consequence of human activity. If these species then threaten indigenous species and biodiversity, and/or cause economic damage, they are referred to as "invasive." Biological invasions are not only one of the greatest threats to indigenous marine biodiversity, but they can also cause massive economic and ecological damage. Their presence could also lead to a water body failing to achieve good environmental status under the forth - coming EU Marine Strategy Framework Directive. As the rate of invasion to Great Britain and European waters continues to increase, particularly in light of climate change, the emphasis by member states is on prevention rather than on control or eradication an NIS once an invasive NIS has become established. This paper reviews NIS biosecurity planning for the marine environ - ment, including the most current legislative background, pathway identification and highlights the main issues with the current risk assessment processes. The potential impacts of marine NIS, practical biosecurity measures from Great Britain and internationally are also reviewed. The aim of this paper is to draw attention to the challenges associated with preventing the introduction of marine NIS and to highlight the urgent need for concerted action across the EU member states and marine industries to produce robust biosecurity plans to protect indigenous species

While oceans are vast, they represent a fragile resource that must be protected if we want to protect our livelihoods and our planet. Marine pollution has been a topic of concern for a long time, and it has recently attracted the attention of scientists, environmentalists, economists, politicians and journalists in mainstream media, . Besides providing food, transportation routes and other resources, the oceans serve as a heat absorbing sink which offsets the extreme heating effects of climate change, but only to a limited degree. Pollution in marine environments such as the oceans, poses a threat to coastal communities by affecting the fauna and flora in the environment and the health of the nearby population. This has a disruptive effect on the health and economy of these communities. Marine Pollution: Current Status, Impacts and Remedies emphasizes the limitations of marine resources that relevant environments provide. Readers will find chapters on methods to assess pollution as well as important information for identifying, measuring, and remediating various pollutants. The book also covers some known pollutants (heavy metals, organic pollutants, microplastics) and ways to manage these substances. Other issues covered in the book include problems caused by invasive species, and the ecological problems caused by pollutants which affect local fauna and flora. This book will prove to be a useful resource for students, researchers, and policymakers, who are working in environmental science, marine conservation and allied fields.

Sustainable marine technologies and innovation - TFI seasprings
TFI Marine places sustainable marine technologies and innovation under the spotlight, starting with a look at floating offshore wind We are on the cusp of a step-change in our ability to unlock previously untapped potential in offshore renewable energy, enabled by technology advances, including a new offshore mooring solution developed by TFI Marine – the SeaSpring – which opens up enormous possibilities for floating offshore wind energy. Wind is a significant global power source and a proven clean energy source, with offshore wind growing rapidly over the past 20 years. In 2022, 39.4% of net electricity generated by the EU was renewable energy, with 15.9% of that wind energy.

Marine pollution occurs today in varied forms--chemical, industrial, and agricultural-and the sources of pollution are endless. In recent history, we've seen oil spills, untreated sewage, eutrophication, invasive species, heavy metals, acidification, radioactive substances, marine litter, and overfishing, among other significant problems. Though marine pollution has long been a topic of concern, it has very recently exploded in environmental, economic, and political debate circles; scientists and non-scientists alike continue to be shocked and dismayed at the sheer diversity of water pollutant
