Underwater Optical Data from the Southern Ocean, 2002-2003 Austral Summer

2002-2003 Austral summer data from the TR/V Umitaka-Maru cruise in the Southern Ocean. It contains spectral radiation, absorption coefficients, volume scattering function, chlorophyll a concentration, phytoplankton pigments concentration (HPLC), and transparency measurements. The data were collected by SCIOPS using seawater samples from several depths via Niskin bottles on a CTD system.

Use Cases

• Modeling phytoplankton biomass distribution based on chlorophyll a concentration and pigment data
• Analyzing light penetration and scattering in polar waters based on spectral radiation and volume scattering function
• Studying seasonal biogeochemical processes in the Antarctic Ocean based on multi-parameter optical measurements

Strengths

• Data includes multiple related optical and biological parameters for a coherent analysis.
• Measurements are from a specific, documented research cruise (TR/V Umitaka-Maru, UM0203).
• Samples were collected from several depths using a standardized CTD and Niskin bottle system.

Limitations

• Last updated 2003-02-10 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
