Scaling Sound Surveys Across Multi-Kilometer Phreatic Systems

When a phreatic system runs past 10 kilometers, single-dive mapping breaks down. EchoQuilt's patch-based quilt stitches multi-kilometer surveys without forcing any single diver to carry the whole map.

Leon Sinks opens into Wakulla, and the mapped phreatic exceeds 58,444 feet — over 11 miles of connected passage on one system alone. The Woodville Karst Plain Project's Chip's Hole–Wakulla connection now extends past 236,723 feet of surveyed conduit. In Quintana Roo, Sistema Ox Bel Ha holds 541.7 km of surveyed passage. No solo diver maps a system at that scale. Bottom time runs out at 90 minutes on a CCR push; DPV penetration caps at 8000 feet before turn pressure; decompression obligation grows faster than swim distance on the far end.
