NBP1405: Underway Multibeam Sonar Data from Antarctic Research Vessel Transit

R/V Nathaniel B. Palmer, an NSF-supported research icebreaker, collected this underway data during leg NBP1405. The leg started at Punta Arenas, Chile and ended at Talcahuano, Chile, supporting global change studies in biological, chemical, physical, and oceanographic disciplines. The dataset is provided by the organization SCIOPS via the NASA Earthdata platform.

Use Cases

• Map seafloor bathymetry and features based on multibeam sonar data mentioned in the title and platform tags
• Analyze vessel transit patterns and environmental conditions based on the underway data collection method
• Study oceanographic properties in the Antarctic region based on the vessel's mission for global change studies
• Calibrate or validate other remote sensing or sonar systems using the collected sea trial data

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, indicating a scientific collection context
• Platform tags specify multibeam sonar and geospatial data, suggesting specific sensor outputs

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count, file formats, and sample data are unknown, which may limit suitability assessment
