| The fine resolution of long geoseismic sections should permit the characterization of oceanic turbulence properties over several decades of horizontal scales. The range of horizontal scales actually probed by three different acoustic sources is found to be directly linked to their frequency content. The horizontal inertial range with a spectral slope of k(h)(-5/3) extend up to 3 km wavelength for the most intense acoustic reflectors which surround strong anticyclonic eddies. The in situ data analysis is confirmed by high resolution numerical simulations of oceanic anticyclonic vortices, in a rotating temperature-stratified fluid (no salt), which show the spontaneous emergence of a concentration of acoustic reflectors above and below the eddy. These show an... |

| This chapter discusses challenges for PhD students involved in integrative landscape research. These challenges include terminology, epistemology, expectations, stakeholder involvement, organizational barriers, communicating and publishing, as well as career development. The chapter presents recommendations for future integrative landscape research involving PhD students and prospects for future education. The recommendations are based on our experiences in research and teaching in general, and on our exchanges with the students in the PhD master class in particular. The recommendations also reflect on the conclusions that can be drawn from the PhD students’ contributions in this book. |
