Agulhas Bank Ocean Glider Data on Dissolved Oxygen Decline

New autonomous ocean glider data from the eastern Agulhas Bank reveals a two-stage deoxygenation mechanism driven by the Agulhas Current. The dataset likely contains measurements of dissolved oxygen, nutrients, turbulence, and stratification from a temperate shelf system off South Africa. It was authored by Juliane U Wihsgott and last updated on May 6, 2026.

Use Cases

• Modeling shelf sea deoxygenation processes based on described stratification and nutrient injection.
• Analyzing the impact of wind-driven coastal upwelling on primary production and oxygen decline.
• Studying western boundary current dynamics and their role in preconditioning shelf seas for oxygen depletion.
• Assessing vertical mixing and ventilation efficiency in subsurface layers based on turbulence measurements.

Strengths

• Includes the first turbulence measurements in the region, providing novel data.
• Focuses on a specific, influential marine system: the Agulhas Bank shelf influenced by the Agulhas Current.
• Released under a CC-BY-4.0 license, facilitating open reuse.

Limitations

• The dataset is described as a PDF file, which may not be a standard tabular format for direct analysis.
• Column-level documentation is absent; field semantics must be inferred from the paper.
• Row count is unknown, which may limit suitability assessment.
