November-December 2001 surface water samples along a transect between Australia and Antarctica recorded phytoplankton cell concentrations ranging from 300,000 to 1,800,000 cells per litre. The dataset likely contains species-level counts and carbon measurements from the CLIVAR-SR3 cruise, collected as part of ASAC project 1343.
Use Cases
- Analyze latitudinal variation in phytoplankton assemblages based on species counts across ocean zones.
- Model relationships between cell carbon content and primary production parameters.
- Study the role of diatoms versus nanoflagellates in particle export based on correlation data.
- Compare phytoplankton community structure between the Sub-Antarctic Zone and Seasonal Ice Zone.
Strengths
- Provides specific cell concentration ranges for different phytoplankton groups (e.g., diatoms 270,000-1,200,000 cells/litre).
- Includes detailed taxonomic information for dominant species like Pseudo-nitzschia spp. and Fragilariopsis spp.
- Links biological data to productivity parameters like nitrate uptake and particle export.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2001-12-14 23:59:59.999000; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
