AbstractMechanical energy plays a prime role in planktonic systems, affecting processes at both large and small scales. In the last decade an increasing interest in the processes at small-scales has flourished. The number of papers related to small-scale turbulence and processes like nutrient uptake and molecular diffusion, trophic interactions and formation of particle aggregates have increased exponentially. Still, our knowledge of how and how much turbulence can affect these processes is scarce and very often derived only from modeling exercises. Field and laboratory data on the effects of small-scale turbulence on plankton (from bacteria to fish larvae) are very scarce. The main reasons for this lack of data are the difficulties in measuring turbulence in the field and both simulating and measuring it in the lab. In addition, we have to deal with intrinsic problems due to the complex nature of the turbulence. To fulfill this lack of knowledge about physical-biological interactions at small scale, multi-disciplinary approaches are necessary. On the one hand, the biologist or the chemist needs the collaboration of physicists and engineers to be able to deal with turbulence. On the other hand, it is desirable to raise the interest of physicists and engineers to the transcendence of small-scale physics to the biological world. With this in mind we organized an Advanced Study Course entitled “Ocean Turbulence: a Basic Environmental Property for Plankton”. This course was part of the training actions developed within Marine Science and Technology (MAST) program of the European Commission. Students and lecturers from very different backgrounds shared their interest in small-scale processes affecting biology, physics and chemistry. This book includes some of the lectures given there. The editors hope that this multidisciplinary volume will contribute to the under-standing of how turbulence, or the instabilities associated with it, may affect plankton, which dwell in the Stokesian realm at scales comparable or even smaller than the Kolmogorov length-scale. We were very satisfied, during the course, with the high degree of interaction between specialists and students from different disciplines and backgrounds. Finally, we want to acknowledge the MAST program of the European Commission and the Consejo Superior de Investigaciones Científicas (CSIC) for its financial support. We also wish to acknowledge the effort of the organizing institutions and the enthusiasm of the course participants. Thanks to all of them for making possible this stimulating activity
