POPS: Polar Ocean Profiling System Buoy Observations from the Arctic

Development of the JAMSTEC Compact Arctic Drifter (J-CAD) began in 1999 in collaboration with METOCEAN. The Polar Ocean Profiling System (POPS) is a new buoy system, developed from J-CAD, that tethers an Argo float to sample oceanographic and atmospheric data from the Arctic multiyear ice region. Deployments have occurred once or twice a year since 2000 to understand Arctic Ocean change.

Use Cases

• Analyze interannual variability of oceanographic conditions based on long-term buoy observations.
• Study atmospheric forcing on sea ice and ice-albedo feedback based on concurrent atmospheric data.
• Model Arctic Ocean changes based on time-series data from the multiyear ice region.

Strengths

• Observations span over two decades, with deployments beginning in 2000.
• Data collection includes a broad suite of concurrent oceanographic and atmospheric variables.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
