Chapter
This chapter provides a concise overview of the entire monograph by assembling summaries of 10 individual chapters starting with a global review of large-scale, persistent nutrient fronts of the World Ocean followed by regional chapters on the Arctic Ocean, North Atlantic, Baltic Sea, Kuroshio Current, and the Yellow Sea, a global review of CDOM dy...

The accumulation of marine litter on coastal seabeds is influenced by various anthropogenic and environmental factors. To identify litter accumulation areas on the seafloor, it is necessary to understand the interaction of these parameters. This study analyses the seafloor litter occurrence in the southeastern North Sea, based on samples collected...

Coastal observatories are key to improve the understanding of processes within the coastal area and their interactions with regional and global environmental changes. The land-sea transition zone is an essential area that allows research on unique scientific questions under anthropogenic and natural influences. Amid the Wadden Sea UNESCO world natu...
Article
Full-text available
The Pacific Ocean constitutes about half of the global oceans and thus microbial processes in this ocean have a large impact on global elemental cycles. Despite several intensely studied regions large areas are still greatly understudied regarding microbial activities, organic matter cycling and biogeography. Refined information about these feature...
Chapter
Lagrangian methods are a common tool in physical oceanography. Due to the quasi-Lagrangian characteristics of floating marine litter (FML) and the chemical substances released from it, Lagrangian methods can be used to study this environmental threat. Most of the existing investigations of this topic have been carried out in the deep ocean, where b...

We examine the relative dispersion and the contribution of tides on the relative diffusivities of surface drifters in the North Sea. The drifters are released in two clusters, yielding 43 pairs, in the vicinity of a tidal mixing front in the German Bight, which is located in the southeastern area of the North Sea. Both clusters indicate decreasing...
Conference Paper
Full-text available
Floating marine litter (FML) is dispersed in the world oceans and poses one of the major threats to marine ecosystems. Lagrangian observations are a fundamental key to gain deeper insights into complex transport processes of FML at the ocean's surface. A number of studies have focused on global, large scale transport modelling of FML by using Lagra...
Conference Paper
Full-text available
Observations using two kinds of drifters were carried out in the southern North Sea aiming to study the propagation pathways of marine litter. One drifter, which was driven by the upper layer currents, was equipped with global positioning system. Further 1,600 wooden drifters, driven mostly by wind and Stokes drift were released offshore in German...

Lagrangian observations are important for the understanding of complex transport patterns of floating macroscopic litter items at the ocean surface. Satellite-tracked drifters and numerical models are an important source of information relevant to transport processes as well as distribution patterns of floating marine litter (FML) on a regional to...
Article
Cruise MSM42 with RV MARIA S. MERIAN dealt with investigating the recent changes in the water mass structure and the oceanic circulation system in a narrow region focusing on the vicinity of Flemish Pass and Flemish Cap located at the western edge of the subpolar North Atlantic. Several densely spaced hydrographic sections were carried out across m...

Marine pollution with plastics is a growing global problem which already shows far-reaching effects on marine ecosystems. This project will provide a sound scientific basis for the understanding of current and future pattern of macroplastic pollution along the northwest German coasts and islands, whilst better identifying polluters and provide solutions to possible abatement strategies. To achieve these goals an inter-disciplinary consortium of physical oceanographers, geoecologists and environmental planers has been formed. The consortium will study pathways and accumulation/beaching areas of marine floating debris in the German Bight and Wadden Sea areas using ultra-high resolution numerical modelling allowing e.g. backtracking of particles to clearly identify the major source regions of plastic pollution (shipping lanes, rivers, tourism). It will provide observational support through nearshore observation of hydrodynamic properties (waves, currents, drifter) and will develop a concept of monitoring and analyzing litter data along the North Sea coast on various temporal and spatial scales with special emphasis on the role of riverine input. The consortium will also focus on the socio-behavioral patterns of people and actors regarding the pollution with macroplastics and the elaboration of appropriate abatement strategies in a participatory way, including the installation of a system for active citizen participation in litter data collection through a mobile phone application and web page service. The results of this project will provide local governmental (National park, NLWKN, etc.) and non-governmental entities with sound scientific data on macroplastic pollution, a solid knowledge on major sources, pathways and accumulation areas of marine debris and will finally provide plans for abatement strategies.
