OverviewObserving plankton growth and decline by species in real time has long been a dream of those who study plankton ecology. Such measurements provide great insights into how primary productivity is related to ecological parameters.
TechnologyThe invention is a system that uses a combination of video and flow cytometric technology to both capture images of organisms for identification and measure chlorophyll fluorescence associated with each image. Images can be automatically classified with software based on a support vector machine, while the measurements of chlorophyll fluorescence make it possible to more efficiently analyze phytoplankton cells by triggering on chlorophyll-containing particles. Quantitation of chlorophyll fluorescence in large phytoplankton cells enables the interpretation of patterns in bulk chlorophyll data, and the discrimination of heterotrophic and phototrophic cells.
