Samuel Monk is currently working towards a PhD with the aim of developing an autonomous Dissolved Inorganic Carbon (DIC) sensor for oceanic measurements, based on the lab on a chip microfluidic system pioneered by the Ocean Technology and Engineering Group (OTE) at the National Oceanography Centre, Southampton. DIC is one of the four parameters measured to quantify the carbon cycle and currently there are no commercially available autonomous DIC sensors. OTE’s microfluidic lab on a chip system offers several advantages for oceanic sensors, such as low power requirements, low reagent consumption, minimised waste, reduced reaction time leading to increased sample frequency and small form factor. By taking advantage of these benefits it means the DIC sensor developed can be easily integrated into a variety of sensor platforms, to improve future spatial and temporal measurements of the carbon system.
