Phytoplankton Bloom Analysis from Satellite and Ship Measurements

Stanford University and AMD_USAPDC research investigates massive phytoplankton blooms along the Australian-Antarctic Ridge, focusing on hydrothermal iron sources. The project combines satellite remote sensing with ship-based measurements and numerical modeling (CROCO) to study biological activity and carbon cycling. Data collection supports doctoral dissertations and was last updated in August 2025.

Use Cases

• Analyze satellite-derived chlorophyll-a concentrations to map the spatial extent of the AAR bloom.
• Correlate ship-based dissolved iron (DFe) measurements with phytoplankton biomass to identify hydrothermal sources.
• Model physical oceanographic processes linking deep DFe reservoirs to surface blooms using CROCO simulation outputs.
• Assess interannual variability in bloom timing and intensity from time-series satellite data.
• Estimate carbon sequestration potential by linking bloom productivity metrics to deep ocean carbon flux.

Strengths

• Interdisciplinary data combining satellite remote sensing with in-situ ship measurements.
• Focus on a large, poorly understood phytoplankton bloom in a critical polar region.
• Research program designed to produce at least two Ph.D. dissertations, indicating depth.

Limitations

• Specific row counts, column names, and dataset size are unknown.
• Geographic coverage is limited to the northwestern Ross Sea sector of the Southern Ocean.
• Data freshness is uncertain beyond the platform's August 2025 metadata update.
