With funds from an NSF Field Stations and Marine Laboratories grant, we completed renovations of the systems supplying water to UGAMI’s seawater laboratories. These facilities allow us to maintain a large variety of tanks and aquaria for studying marine organisms in a controlled setting. The new system is far superior to the one it replaced. It can supply up to 75 gallons of seawater per minute; monitors the creek level and only runs the pumps when the intakes are submerged (preventing damage caused by the pumps running dry); incorporates five 3,000-gallon modular storage tanks to supply seawater at low tide (when the pumps are off); actively manages the pressure in the seawater line to maintain consistent flow; and provides several filter options, including bag filters, a radial flow settler, bead filter, and in-line UV sterilization, so we can supply seawater to suit the needs of any research user. In addition, we have just taken possession of three 1,000-gallon tanks for maintaining and studying larger fish and two 8’ sink trays for washing and processing samples of marsh plants.
