Phytoplankton Colour Index (PCI)

After the silk has been marked into 5 nautical mile samples but prior to cutting, each sample is visually assigned a greenness index by comparison with standard colour charts: viz. no colour, very pale green, pale green, and green. These four levels of the phytoplankton colour index (PCI) represent the amount of phytoplankton pigment on the silk and have been assigned numerical values on a ratio scale based on acetone extracts using spectrophotometric methods.

Results from the AusCPR survey are available through the AODN portal: https://portal.aodn.org.au This data is freely available but please acknowledgment all relevant parties, as detailed in acknowledgement section.
