SEMINAR: Keeping tabs on the ocean CO2 cycle using new autonomous observing technologies

 

Abstract:  The ocean carbon cycle is undergoing unprecedented changes and, therefore, carbonate system parameters have been assessed by the Global Ocean Observing System (GOOS) as the highest impact biogeochemical Essential Ocean Variables (EOVs). Accurate carbonate chemistry characterization is required to understand the oceanic carbon cycle and monitor ocean acidification and hence consequences for marine (particularly calcifying) organisms.  Although efforts have been made to increase the availability of high-resolution carbonate chemistry measurements in the ocean, the lack of automated high-performance low-cost carbonate sensors continues to hinder continuous and spatially extensive carbonate chemistry measurements using autonomous platforms. Developing sensors capable of fulfilling future autonomous deployment goals is therefore key for deciphering knowledge gaps and uncertainties in our understanding of the global ocean carbon cycle and optimisation of global models of ocean acidification and its impacts. In this talk I will present recent developments in autonomous carbonate sensor technologies showcasing some novel observing capabilities and successes, finishing with a glimpse on what ocean carbon observing may look like in the near future.   


Speaker: Dr. Socratis Loucaides

Speaker bio: Dr. Socratis Loucaides is an ocean scientist with expertise in chemical oceanography and autonomous ocean observing. He completed his undergraduate studies at the University of North Carolina and PhD at Utrecht University. He held research positions at the Marine Environmental Laboratory of the International Atomic Energy in Monaco and University of Southampton and since 2013 at the National Oceanography Centre, where he leads a team of scientists developing novel technologies for monitoring and understanding ocean biogeochemistry. As a principal investigator, he leads the development of carbonate sensor technologies and he is the technical innovation expert of ICOS-OTC (Integrated Carbon Observation System - Ocean Thematic Centre) in Europe. Current projects involve technology development for long-term sustained carbon observations, carbon dioxide removal/storage Monitoring Reporting and Verification (MRV) and capacity building for ocean acidification monitoring.
