Entrainment and bending in a major hydrothermal plume, Main Endeavour Field, Juan de Fuca Ridge
[1] We measure expansion rate and bending in a 23-hour time series of acoustic images of the lower 25 m section of a buoyant hydrothermal plume rising from Grotto vent in the Main Endeavour Field, Juan de Fuca Ridge. We then calculate entrainment coefficient, the constant of proportionality relating mean inflow velocity at the plume edge to maximum mean upward velocity within the plume. The plu...
متن کاملAcoustic Instrumentation for Imaging and Quantifying Hydrothermal Flow in the NEPTUNE Canada Regional Cabled Observatory at Main Endeavour Field
The National Science Foundation Oceanographic Technology and Interdisciplinary Coordination (OTIC) program funded the engineering development and connection of the sonar instrument package to the Endeavor node of the NEPTUNE Canada Stage 1 component of the Regional Cabled Observatory (RCO) in the Main Endeavour Field (MEF) on the northern Juan de Fuca Ridge as part of the Ocean Observatories In...
متن کاملRhythms and Community Dynamics of a Hydrothermal Tubeworm Assemblage at Main Endeavour Field – A Multidisciplinary Deep-Sea Observatory Approach
The NEPTUNE cabled observatory network hosts an ecological module called TEMPO-mini that focuses on hydrothermal vent ecology and time series, granting us real-time access to data originating from the deep sea. In 2011-2012, during TEMPO-mini's first deployment on the NEPTUNE network, the module recorded high-resolution imagery, temperature, iron (Fe) and oxygen on a hydrothermal assemblage at ...
متن کاملFree-living bacterial communities associated with tubeworm (Ridgeia piscesae) aggregations in contrasting diffuse flow hydrothermal vent habitats at the Main Endeavour Field, Juan de Fuca Ridge
We systematically studied free-living bacterial diversity within aggregations of the vestimentiferan tubeworm Ridgeia piscesae sampled from two contrasting flow regimes (High Flow and Low Flow) in the Endeavour Hydrothermal Vents Marine Protected Area (MPA) on the Juan de Fuca Ridge (Northeast Pacific). Eight samples of particulate detritus were recovered from paired tubeworm grabs from four ve...
متن کاملKinetics of Fluid Phase Separation
We review understanding of kinetics of fluid phase separation in various space dimensions. Morphological differences, percolating or disconnected, based on overall composition in a binary liquid or density in a vapor-liquid system, have been pointed out. Depending upon the morphology, various possible mechanisms and corresponding theoretical predictions for domain growth are discussed. On compu...
