The goal of the symposium is to increase the impact of the new knowledge generated from these unique datasets and to foster new collaborations among aquatic microbial ecologists, evolutionary biologists, oceanographers, limnologists, cell and molecular biologists, geneticists, and more. The objective is also to address “What questions can we now ask because of the completion of the marine field campaigns and with the arrival of new technologies, methods, and concepts from all corners of the biological sciences?”
