OPP-PRF: Remote Pathways of Ocean Heat Transport toward the Antarctic Ice Sheet is a NASA Earthdata project investigating mechanisms linking offshore ocean circulation to Antarctic ice melt. AMD_USAPDC researchers will use Lagrangian particle experiments in a Southern Ocean state estimate and autonomous float data from West Antarctica. The project aims to quantify pathways of Circumpolar Deep Water from the Antarctic Circumpolar Current to the continental slope.
Use Cases
- Analyze Lagrangian particle trajectories to quantify seasonal variability in Circumpolar Deep Water pathways.
- Validate model-derived heat transport mechanisms using autonomous profiling float data from West Antarctica.
- Statistically constrain interannual variability in remote ocean heat transport pathways toward the Antarctic Ice Sheet.
- Determine physical mechanisms governing variability in CDW pathways from the ACC to the continental slope.
- Investigate cascading effects of offshore ocean current changes on the heat supply to the ice sheet.
Strengths
- Analysis based on a data-assimilating state estimate of the Southern Ocean.
- Combines model experiments with observational data from autonomous profiling floats.
Limitations
- Dataset size, row count, and specific column structure are unknown.
- Geographic coverage may be focused on the West Antarctic region and Southern Ocean.
- Data completeness and availability are uncertain as the project is ongoing.
