RV Investigator IN2023_V06: Plankton Images from the East Australian Current

High-resolution plankton images were collected from the East Australian Current system between October 9 and November 2, 2023. The dataset is a dynamic, 'living' collection hosted on EcoTaxa, undergoing ongoing validation and expansion by researchers Dr. Alice Della Penna and Dr. Alexandre Lheriau-Nice. This research was supported by a grant of sea time on the CSIRO Marine National Facility's RV Investigator.

Use Cases

• Automated taxonomic classification of planktonic organisms based on high-resolution images.
• Assessing biodiversity and ecological patterns in the East Australian Current system based on plankton samples.
• Training and validating machine learning models for plankton image recognition based on the EcoTaxa-hosted dataset.
• Studying the impact of ocean eddies on plankton communities based on samples collected during the specific voyage.

Strengths

• Images are high-resolution, captured with a dedicated PlanktoScope imaging system.
• Data collection is tied to a specific, well-documented research voyage (IN2023_V06) with known dates and location.
• The dataset is described as dynamic, with ongoing validation efforts to improve classification accuracy.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes inconsistencies in classification, particularly within the Radiozoa group.
