Collaborative Research data from a 2017 oceanographic cruise to the Ross Sea polynyas, led by institutions including UT-San Antonio and Columbia University. The project deployed UASs, AUVs, and ROVs to measure atmospheric, oceanic, and sea ice properties during the austral fall. Its main goal is to improve estimates of sea ice production and water mass transformation in a region showing consistent sea ice increases.
Use Cases
- Modeling air-sea-ice interaction processes based on concurrent atmospheric, oceanic, and sea ice measurements.
- Validating remote sensing algorithms for sea ice detection based on in-situ measurements of ice thickness and snow depth.
- Analyzing polynya dynamics and their role in sea ice production based on data from Terra Nova Bay and Ross Ice Shelf polynyas.
- Studying the impact of seasonal sea ice changes on global ocean circulation patterns based on water mass transformation data.
Strengths
- Data collection involved a multi-institutional collaborative effort, including UT-San Antonio, Columbia University, and Woods Hole Oceanographic Institute.
- Field campaign deployed multiple advanced research tools including unmanned airborne systems (UASs), autonomous underwater vehicles (AUVs), and remotely operated underwater vehicles (ROVs).
- Measurements were designed to capture concurrent atmospheric, oceanic, and sea ice properties and processes.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
