SeaFlow is a novel underway flow cytometer created at UW by Jarred Swalwell that is designed to measure continuously the abundance and composition of microbial populations, making it possible to analyze the equivalent of one sample every three minutes. The instrument collects information about the size and pigment content of an individual cell and counts several thousands cells every second in real-time. The instrument utilizes light scattering and autofluorescence properties of individual cells to discriminate and quantify different cell populations that span 0.5-15 micrometer in size. The instrument is semi-autonomous and can be controlled remotely via Satellite connection.
SeaFlow data are processed at the Armbrust Lab by Francois Ribalet. Data are publicly accessible in SQLshare and abundance and optical properties of of the different microbial populations can be visualized using our web interface. Distribution of microbial population can also be visualized in Google Earth. Clic on the cruise track to download individual KML file.
