Abstract


LEVANTINE BIOGEOCHEMICAL CYCLING ELUCIDATED BY GLIDER DATA FOR THE PERIOD 2009-2014

The Levantine Sea is one of the most oligotrophic oceanic bodies of the planet, characterized by very low nutrient concentrations and low productivity. Efforts to study its biogeochemical functioning through ship-board time-series and isolated regional cruises are hindered by a relatively complex, spatially variable and dynamic mesoscale and submesoscale circulation field. Satellite remote-sensing may cover the necessary lateral spatial resolution but fails to penetrate sufficiently deep to record sub-surface features. Autonomous platforms such as gliders and floats address the need for synoptic broad-range highly-resolved observations eminently. We illustrate their capacity by analyzing and presenting glider biogeochemical sensor data from several missions in the Levantine Sea during the period 2009-2014. We explore the effects of seasonality, mesoscale and sub-mesoscale circulation features, etc., on productivity, respiration, and other processes of interest, and highlight the potential of gliders to significantly contribute to better understanding of biogeochemical cycling in the region.
