Explore cutting-edge ocean science research in this plenary lecture series from the 2018 Ocean Sciences Meeting. Dive into two fascinating presentations: "The building blocks of life: From oceanic to molecular scales and back again" by Claudi Benitez-Nelson, and "Biological Propulsion in (and of?) the Ocean" by John Dabiri. Discover the intricate relationships between oceanic and molecular scales, examining topics such as the Redfield Ratio, global biogeochemical cycles, sinking particle stoichiometry, and the role of phosphorus in marine ecosystems. Gain insights into biological propulsion in ocean environments and its potential implications. Engage with cutting-edge research that bridges multiple disciplines, including marine science, environmental engineering, and mechanical engineering, to deepen your understanding of complex ocean processes and their global significance.
