IMIS

This dataset contains results from Continuous Plankton Recorder (CPR) surveys in the Southern Ocean. When the opportunity arises, zooplankton species, numbers and abundance data are recorded on a continuous basis as vessels steam through the area between Australia and Antarctica, including Heard and Macquarie Islands. Observations have been made since June 1990 and are ongoing. Obviously the observations are not continuous over the region with time. Many of the original CPR logbooks from the various voyages have also been scanned, and are available via the Australian Antarctic Data Centre's Reports Register. The fields in this dataset are:
