The Phytoplankton Time Series at Port Aransas is part of the Mission-Aransas National Estuarine Research Reserve (MANEER) program.



The Imaging FlowCytobot (IFCB) is deployed in the pier laboratory at the University of Texas-Marine Sciences Institute (, located on the Port Aransas ship channel at the entrance to the Mission-Aransas estuary on the Gulf of Mexico (27.84°N, 97.07°W).


There are very strong currents in the ship channel which makes submersible deployment difficult, so IFCB is installed in the laboratory at the seaward end of the pier and sea water is pulled up to the instrument by a peristaltic pump. The pump is located beyond the IFCB sampling point so sample water did not pass through the pump.
