Southern Ocean Underwater Optical and Biological Measurements from 2004-2005

2004/2005 Austral summer measurements of spectral radiation, absorption coefficients, volume scattering function, chlorophyll a concentration, phytoplankton pigments concentration (HPLC), and transparency in the Southern Ocean. The data were collected during the cruise of TR/V Umitaka-Maru. Seawater samples were obtained from several depths using a Niskin bottle on a CTD system.

Use Cases

• Modeling underwater light fields based on spectral radiation and volume scattering function data.
• Analyzing phytoplankton biomass and community structure based on chlorophyll a and HPLC pigment concentrations.
• Studying water clarity and optical properties based on absorption coefficients and transparency measurements.
• Calibrating satellite ocean color algorithms based on in-situ optical and biological profiles.

Strengths

• Data includes multiple co-located optical and biological parameters for the Southern Ocean.
• Samples were collected from several depths using a standardized CTD and Niskin bottle system.
• Temporal coverage is specified as the 2004/2005 Austral summer.

Limitations

• Last updated 2005-01-22 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
