'The BARKLEY CANYON AND SLOPE DYNAMICS working group is composed of the research community interested or engaged in the analysis of ONC Barkley Canyon and slope data streams. This community shares broad interests in the understanding of physical, geological and biological processes within and surrounding Barkley Submarine Canyon. Examples of physical process are internal tide focusing and propagation, vertical mixing and upwelling triggering. Geological processes include sediment transport, slope instability triggering turbidity events and nepheloid layers. Biological processes include the trapping and concentrating zooplankton layers, dynamic of organic matter pulses to the seafloor affecting benthic community structure and ecosystem functioning. The working group helps the user community to plan for multidisciplinary experiments, share and collaborate in new project ideas, discuss potential publications and prepare for the yearly ONC cruise planning season. The working group is also a virtual space for ONC staff scientists to provide updates on issues with instruments and sensors and quality control of data streams.
