Submerged Tide Gauge Records from Zhong Shan, Antarctic (2000-2011)

2000-2011 tidal records from a submerged pressure gauge in Nella Fjord, Larsemann Hills, near the Zhong Shan station in the Australian Antarctic Territory. The gauge was designed by Platypus Engineering and deployed in 1991/2, with data retrieved via an inductive loop through the ice. Records are managed by the Australian Antarctic Data Centre (AU_AADC) and were last updated in 2011.

Use Cases

• Modeling tidal patterns in Antarctic fjords based on the continuous pressure measurements.
• Analyzing long-term sea-level variability based on the 2000-2011 time series.
• Calibrating satellite altimetry data using the high-accuracy (+/- 3 mm) in-situ ground truth.
• Studying the deployment and performance of submerged sensor technology in extreme polar environments.

Strengths

• High measurement accuracy, with the system reported to be better than +/- 3 mm for a known water density.
• Records are described as complete since the gauge's deployment.
• Gauge was secured in a concrete mooring and undisturbed, suggesting consistent measurement conditions.

Limitations

• Last updated 2011-07 26 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description mentions the battery was probably exhausted by 2008, which may affect later data continuity.
