SEARCHING THE WSPR BLOCK.
GROK:
Actionable Plan: Deploy AUV Magnetometer Swarm for MH370 Search – WSPR Block Only
Target Zone (the WSPR-proposed site per Richard Godfrey analysis, March 2026)
The dramatically smaller area (≈1/5th the size of the previous 15,000 km² proposal) plus wider line spacing and lighter payloads deliver 60–75% cost reduction vs. full-sonar campaigns.
This is the single defined target under the WSPR (Weak Signal Propagation Reporter) hypothesis promoted by Richard Godfrey. If the WSPR-derived flight path and endpoint are correct, detection probability is high:
the 777’s ferromagnetic components (engines, gear, steel) would produce clear magnetic anomalies detectable at 100–300 m laterally even if partially buried.
Immediate Next Steps
It leverages the identical magnetometer-swarm technology proven effective for ferrous wreckage detection.
Target Zone (the WSPR-proposed site per Richard Godfrey analysis, March 2026)
- Compact circular area, 30 km radius, centred on 29.128°S, 99.934°E (recent refinements to ≈29.17885°S 99.85352°E).
- Core area ≈2,827 km² (operational block 3,000–4,000 km² with buffer for edge effects).
- Located ≈1,560 km west of Perth, Australia; water depths 3,750–4,000 m.
- Completely outside (and ~450 km north of) the Inmarsat 7th-arc IG Hotspot / Ocean Infinity 2025–2026 search zone (33°S–36°S). Prior 2018 coverage in the wider region was partial and low-resolution; the core WSPR circle remains essentially unsearched.
- Swarm of 6 deep-rated AUVs (Kongsberg HUGIN 6000-class, Teledyne REMUS 6000, or Argeo SeaRaptor equivalents, 6,000 m rated).
- Primary payload: towed Overhauser magnetometer (Marine Magnetics Explorer or equivalent, 0.001 nT resolution) or 3-axis gradiometer array. Minimal secondary sensors only (INS/DVL, USBL, altimeter, CTD) — no side-scan sonar.
- Pattern: lawnmower or concentric tracks optimised for circular zone, 200–400 m line spacing (coarse first pass), 30–50 m altitude, 3–4 knots.
- Coverage: 240–480 km² per day (swarm total). Full 3,000–4,000 km² block: 7–18 operational days at sea (incl. 20–30% overlap, infill, weather downtime).
- Phased rollout unnecessary due to small size — one continuous sweep feasible; ROV follow-up on any >200 × 200 m magnetic contacts; onshore AI anomaly detection.
- Mothership: single 50–80 m mid-size survey/OSV vessel with LARS, based out of Fremantle/Perth (≈1,200–1,500 nm transit).
- Ocean Infinity — operates in the broader region, has vessels and HUGIN-style fleets already familiar with southern Indian Ocean logistics; could add this compact block under an extended no-find-no-fee contract. (Not likely as they are not WSPR 'followers')
- Deep Ocean Search (DOS) + Deep Sea Vision — HUGIN 6000 swarms with magnetometer capability, proven on aircraft debris searches.
- Argeo or Oceaneering — AUV contractors experienced in leased fleets and magnetometer surveys.
Approach Malaysian authorities for partnership; a smaller block makes a performance-based contract more attractive.
- Planning / contracting / data refinement / mobilisation: 2–4 months (Q2–Q3 2026).
- At-sea execution: next optimal weather window — Southern Hemisphere summer, November/December 2026 – February 2027.
- Total campaign duration: 6–10 weeks (incl. transit and contingency) — far shorter than the 15,000 km² arc block.
The dramatically smaller area (≈1/5th the size of the previous 15,000 km² proposal) plus wider line spacing and lighter payloads deliver 60–75% cost reduction vs. full-sonar campaigns.
- Estimated full 3,000–4,000 km² campaign: US$4–12 million (mid-size vessel + 6 leased AUVs + crew + processing).
- Breakdown: vessel ops ≈US$30–60k/day; swarm daily rates + logistics ≈US$15–25k total; mobilisation/transit lower due to shorter duration.
- Best structure: “no-find, no-fee” with success payment US$20–40 million.
- Phase-1 core circle could be completed for under US$3–6 million. Figures are realistic for commercial deep-ocean AUV magnetometer surveys in the region.
This is the single defined target under the WSPR (Weak Signal Propagation Reporter) hypothesis promoted by Richard Godfrey. If the WSPR-derived flight path and endpoint are correct, detection probability is high:
the 777’s ferromagnetic components (engines, gear, steel) would produce clear magnetic anomalies detectable at 100–300 m laterally even if partially buried.
Immediate Next Steps
- Contact Ocean Infinity (?) and Deep Ocean Search for quotes tailored to this compact block.
- Request latest refined polygons and WSPR data overlays from Richard Godfrey / mh370search.com team.
- Approach Malaysian Ministry of Transport with a low-cost, high-speed proposal under no-find-no-fee terms.
It leverages the identical magnetometer-swarm technology proven effective for ferrous wreckage detection.
