The Coastal Sciences Division, part of the Energy and Environment Directorate, includes technical experts in quantifying and improving environmental performance of renewable ocean energy systems through environmental monitoring and technology development, carbon/nutrient dynamics and processes at the terrestrial/aquatic interface, research on algal productivity for use in biochemical and biofuels, targeted element extraction from marine waters, and sequestering carbon, understanding biogeochemical processes in sediments and surface waters, coastal ecosystem functions and restoration ecology, biofouling and biocorrosion science, ultra trace analytical chemistry, signature discovery, marine hydrodynamic modelling, and extreme events research. Our more than 1,700 staff support the Department of Energy (DOE), delivering on key DOE mission areas including: modernizing our nation's power grid to maintain a reliable, affordable, secure, and resilient electricity delivery infrastructure; research, development, validation, and effective utilization of renewable energy and efficiency technologies that improve the affordability, reliability, resiliency, and security of the American energy system; and resolving complex issues in nuclear science, energy, and environmental management.
