June 1990 onward observations of zooplankton species and abundance from Continuous Plankton Recorder surveys between Australia and Antarctica. Data includes species counts, developmental stages, and precise geospatial-temporal coordinates for each sampling segment. The dataset is maintained by the Australian Antarctic Data Centre.
Use Cases
- Analyze zooplankton species distribution based on latitude and longitude coordinates.
- Study temporal trends in total abundance and species counts based on observation dates spanning decades.
- Model plankton developmental stage dynamics based on separately counted copepodites, nauplii, calyptopis, and furcilia.
- Standardize and compare sampling volumes across voyages using recalculated segment_length field.
- Correlate phytoplankton color index visual estimations with zooplankton abundance data.
Strengths
- Observations span from June 1990 and are ongoing, providing a long-term time series.
- Zooplankton are identified to the lowest possible taxon, usually species, with detailed developmental stage counts.
- Includes recalculated true segment_length for accurate volume standardization.
- Geospatial coordinates (latitude, longitude) and precise UTC observation dates are provided for each segment.
Limitations
- Observations are not continuous over the region with time, as stated in the description.
- Row count, file formats, and license information are unknown.
