YOUMARES 8 – Oceans Across Boundaries: Learning from each other

This open access book presents the proceedings volume of the YOUMARES 8 conference, which took place in Kiel, Germany, in September 2017, supported by the German Association for Marine Sciences (DGM). The YOUMARES conference series is entirely bottom-up organized by and for YOUng MARine RESearchers. Qualified early career scientists moderated the scientific sessions during the conference and provided literature reviews on aspects of their research field. These reviews and the presenters’ conference abstracts are compiled here. Thus, this book discusses highly topical fields of marine research and aims to act as a source of knowledge and inspiration for further reading and research

YOUMARES – A Conference from and for YOUng MARine RESearchers

YOUMARES is an annual early-career scientist conference series. It is an initiative of the German Society for Marine Research (DGM) and takes place in changing cities of northern Germany. The conference series is organized in a bottom-up structure: from and for YOUng MARine RESearchers. In this chapter, we describe the concept of YOUMARES together with its historical development from a single-person initiative to a conference venue of about 200 participants. Furthermore, the three authors added some personals experiences and insights, what YOUMARES means to them

YOUMARES 9 - The Oceans: Our Research, Our Future

This open access book summarizes peer-reviewed articles and the abstracts of oral and poster presentations given during the YOUMARES 9 conference which took place in Oldenburg, Germany, in September 2018. The aims of this book are to summarize state-of-the-art knowledge in marine sciences and to inspire scientists of all career stages in the development of further research. These conferences are organized by and for young marine researchers. Qualified early-career researchers, who moderated topical sessions during the conference, contributed literature reviews on specific topics within their research field

Ballast Water Risk Indication for the North Sea

The ballast water from ships carries marine organisms that have invasivepotential. The International Maritime Organization Ballast WaterManagement Convention (2004) requires ballast water exchange orballast water management (BWM) systems either onboard or ashore.Ships can be exempted on the basis of risk assessment, when exclusivelysailing between specific ports or in an enclosed area. In reply to ourquestionnaire, the shipping sector argues that the North Sea isecologically homogeneous and exemptions could therefore be granted.This paper proposes that the North Sea area is, in fact, not homogeneousin terms of hydrographical and biological conditions; therefore, ballastwater is a relevant transport mechanism for organisms. Within the NorthSea, the short shipping routes indicate a high risk for survival. Weexamined actual simulation models for ballast water risk assessment inthe North Sea, and we have identified the major parameters that need tobe included in such models. These models provided a basis; they furtherneed to be combined and adapted for the purpose of evaluating therationale for an exemption. We concluded that exemptions from BWMare not recommended for the North Sea area. Anticipating the BallastWater Management Convention, ship owners might do well to studypossibilities for installing BWMsystems onboard
