Southern Ocean Diatom Photographs from Kerguelen Plateau Sediment

Kerguelen Plateau diatom photographs document over 50 species identified from seafloor sediment samples. The collection was compiled by Jessica Wilks for a Macquarie University honours project submitted in May 2012. Data originates from sediment samples collected at 7 locations during the 2011 KEOPS2 research expedition.

Use Cases

• Classify diatom species from light microscopy images for taxonomic studies.
• Analyze species assemblage patterns across 7 distinct sampling locations (A3-1, A3-2, etc.).
• Map the distribution of over 50 diatom species in relation to the Kerguelen Plateau geography.
• Use image data to train computer vision models for automated diatom identification.

Strengths

• Includes photographs for each diatom specimen encountered in the study.
• Covers over 50 identified diatom species from a focused research expedition.
• Spatially specific data from 7 sampled locations around the Kerguelen Plateau.

Limitations

• Sample size (number of images/rows) is unknown.
• Data is over a decade old, collected in 2011-2012.
• Limited to seafloor sediment samples, not capturing water column or living communities.
