Dispersion of produced water in a coastal environment and its biological implications
Produced water, a pollutant associated with offshore oil production, has been shown to have adverse effects on marine organisms. We conducted a study of the dispersion of a produced water plume from an outfall in the Santa Barbara Channel near Carpinteria, CA. Biological effects were studied previously in a series of experiments which examined the toxicity of ocean waters near the outfall. To d...
متن کاملMapping Ocean Outfall Plumes and their Mixing using Autonomous Underwater Vehicles
This paper reports on our experiences developing methods to survey an ocean outfall discharge plume using an Autonomous Underwater Vehicle (AUV). . The mobility of an AUV provides a significant advantage in surveying discharge plumes over traditional boat-based methods, and when combined with optical and oceanographic sensors, provides a capability for both detecting plumes and assessing their ...
متن کاملEffluent Mixing Modeling for Liquefied Natural Gas Outfalls in a Coastal Ecosystem
Liquid Natural Gas (LNG) processing facilities typically are located on ocean shores for easy transport of LNG by marine vessels. These plants use large quantities of water for various process streams. The combined wastewater effluents from the LNG plants are discharged to the coastal and marine environments typically through submarine outfalls. Proper disposal of effluents from an LNG plant is...
متن کاملGeostatistical Mapping of Outfall Plume Dispersion Data Gathered with an Autonomous Underwater Vehicle
The main purpose of this study was to examine the applicability of geostatistical modeling to obtain valuable information for assessing the environmental impact of sewage outfall discharges. The data set used was obtained in a monitoring campaign to S. Jacinto outfall, located off the Portuguese west coast near Aveiro region, using an AUV. The Matheron’s classical estimator was used the compute...
متن کاملThe dynamics of the Mississippi River plume: Impact of topography, wind and offshore forcing on the fate of plume waters
[1] High‐resolution numerical simulations of the northern Gulf of Mexico region using the Hybrid Coordinate Ocean Model (HYCOM) were employed to investigate the dynamical processes controlling the fate of the Mississippi River plume, in particular the conditions that favor cross‐marginal transport. The study focuses on the effects of topography, wind‐driven and eddy‐driven circulation on the of...
