SECOORA Partners Trace Flow of Currents from Rivers to Reefs

Gray’s Reef National Marine Sancutary staff joined researchers from Georgia Southern University to release 50 gallons of fluorescent red dye into the Altamaha River outflow on September 9, 2014. The plume of dye that results, will be monitored visually and with instrumentation as it flows from the release point along the Georgia coast and offshore. Tracking the path of the dye will provide estimates of the extent to which the Altamaha River delivers dissolved substances, including contaminants and nutrients, along the Georgia coast and to hard-bottom reefs, such as Gray’s Reef National Marine Sanctuary, occurring up to 20 miles offshore.
In addition to releasing the dye, 2 satellite-enabled drifters will be deployed to collect information on how larger materials, such as dead stalks of marsh grass, may disperse after being transported by ocean currents from the Altamaha River estuary.
Local teachers were engaged in building the drifters and data obtained from the drifter paths will be made available to the public and to local school teachers for use in the classroom. As with the buoys, these drifters will be clearly labeled so please do not remove them if spotted offshore. Alternatively, please contact the investigators if a drifter is found to have come ashore.
Drifters trajectory path will be coming soon on the SECOORA website! Check back for updates.
