Baltic TRANSCOAST studies the physical, biogeochemical, and biological processes at the land-ocean interface. The coastal zone is heavily impacted by various human activities as well as by geo-morphological and climatic processes. The fluid dynamics, cycling and transport of essential and trace elements and linkages to organisms at the land-ocean interface are closely related. Until now, these interactions are not well understood hampering future planning and management. Especially human impacted coastal fens with little elevation above sea level have rarely been studied in conjunction with marine sciences. Fen systems are potentially a significant source of various compounds to the ocean and on the other hand saline water may impact the land-based processes. Therefore, closely linked investigations have been planned among the faculties of the University of Rostock and the Leibniz Institute for Baltic Sea Research. All institutions will contribute to a closely linked interdisciplinary research concept including biologists, chemists, geologists and environmental scientists. The department of “Maritime Systems” at the Interdisciplinary Faculty of the University of Rostock unifies the researchers under a formal framework and has strengthened collaborations in the past. The newly established Leibniz-Research-Campus Phosphorous is a strong additional driver fostering collaborative research in Rostock. The closely to Rostock located “Hütelmoor” is a suitable coastal fen area, representative for the Baltic region, to integrate the interdisciplinary work of all partners. Moreover, international partners from the Baltic Sea Region are included in this research effort and will contribute to the science and education. Baltic TRANSCOAST aims to win the best candidates as PhD students at a dedicated workshop with international participation. Additional workshops are planned to broaden the expertise of the students, and a Baltic TRANSCOAST session at a major conference will further motivate students to compete at an international level. The study program is structured in six topics and will be realized with an increasing engagement of the students. Thereby, in Baltic TRANSCOAST young academics with broad and interdisciplinary expertise in coastal research will be qualified.
