Input from rivers and estuarine exchange on to the continental shelf plays an important role in altering physical, biogeochemical and ecological functioning of the coastal ocean. This input may influence stratification, nutrient flux, and local circulation patterns altering lower trophic levels and primary productivity. While previous studies have addressed general aspects of the structure and dynamics of river plumes, most of this work has focused on plumes formed by large and medium-size rivers. Little attention has been paid to small rivers plumes and estuarine exchange, largely because small plumes and estuarine exchange is highly dynamic and varies across short temporal (of order of hours) and spatial scales (1-10kms). This variability hinders precise measurements of plume structure and content even though small rivers influxes of fluvial water and suspended sediments is estimated at about 25% and 40%, respectively (Milliman and Syvitski, 1992; Milliman et al.,1999).
This project aims to advance our understanding of the role of small river plumes and estuarine exchange in driving the ecological functioning of the coastal ocean. Given the highly dynamic nature of small plumes, this work will employ a multidisciplinary approach encompassing satellite remote sensing and in situ/adaptive sampling with autonomous underwater vehicles to develop high-frequency, high-resolution, 3D sampling of the physical chemical and biological variables of plume structure and content.
