The development of autonomous chemical analyzers for ocean observatories and aquaculture in California
Maxime Grand, Assistant Professor, Moss Landing Marine Laboratories (MLML), San José State University
Abstract: Progress and discovery in marine biogeochemistry is limited by our ability to obtain widespread measurements over a range of appropriate time scales. While several robust sensors are now routinely used for some key variables, the vast majority of nutrient and trace metals measurements still rely on technologies that were developed decades ago and are inherently unsuitable for unattended operation at coastal observatories. In this presentation, I will describe a new commercially available microfluidic technique, which through its small size, minimal reagent use, and minimized maintenance requirements, is well suited for in situ operation while matching the analytical capabilities of traditional analyzers. I will close by discussing our new research at the MLML aquaculture facility, including the need to constrain the emission rates of volatile bromocarbons (e.g., bromoform) from seaweed species that may soon be mass produced to generate feed additives to reduce methane emissions from ruminant livestock.
Bio: Maxime Grand is a chemical oceanographer and analytical chemist. His research primarily revolves around the biogeochemical cycling of nutrients and trace metals, and in the application of novel microfluidic techniques to improve the spatial and temporal resolution of chemical measurements in coastal and open ocean settings. He received his B.S and Ph.D. from the University of Hawai‘i at Mānoa, M.S from the University of Plymouth (UK) and did a postdoc at the National Oceanography Centre Southampton (UK). He is now Assistant Professor at the Moss Landing Marine Laboratories (MLML), San José State University.
