but not counted” and are not quantified or incorporated into summary statistics. The data available for download from the web interface include phytoplankton cell densities and biovolumes, and zooplankton densities, grouped by major taxonomic category. Counts by individual taxa will eventually be added to the web page, but are currently available only by request. Multiprobe data were made available for download via the website in 2014. Additional tables store tributary flow data, wastewater treatment facility data, plankton taxonomic information, and station location coordinates. These data are not available through the web page but can be obtained by request. Mysid and spiny waterflea data are housed with the NY DEC and also available upon request. Table 4.
