Tara Nutrient and Flow Cytometry Data

"Tara Oceans systematically collected ~35,000 samples for morphological, genetic, and environmental analyses using standardized protocols across multiple depths at global scale, aiming to facilitate a holistic study on how environmental factors and biogeochemical cycles affect oceanic life. ... Tara Oceans collected seawater samples within the epipelagic layer, both from the surface water and the deep chlorophyll maximum (DCM) layers, as well as the mesopelagic zone." (1)<br> Data provided for time, lat, and lon are mean values based on CTD casts that matched closest in location and depth of the actual sampling locations. This dataset includes environmental, nutrient, diversity, and flow cytometry data associated with samples found in the Tara Eukaryote Annotated 18s OTU Counts and Tara Prokaryote Annotated 16s OTU Counts datasets.
