Panacea, FL Coastal Erosion Rate
Shoreline change 7 miles south of Panacea, FL
Good news, and an honest one: USGS's data can't distinguish this stretch, 7 miles south of Panacea, FL, from a flat trend. Whatever small movement it measured here is statistical noise, not a reliable direction, so none is claimed.
What "Panacea" means on this page
USGS surveys the coast in transects spaced a few hundred feet apart; this page groups the nearest ones into a single ~3.5-mile reading for the stretch closest to Panacea, FL, rather than showing one arbitrary line. Segment center: 29.93, -84.41. The survey behind it runs to 2001, in USGS's Gulf of Mexico assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
How solid is this number
Averaging 41 separate transects produced this segment's rate, with 88% individually reading as erosion, rather than relying on any single survey line. The published margin on this reading runs ±0.78 ft/yr. The unadjusted figure here, -0.31 ft/yr, would place it 400 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2004-1089. For scale: Seaside, OR, 2389 miles away, ranks 1155 of 1211 nationally for growth, 1.99 ft/yr. Panacea, FL, 1.8 miles off, is the adjacent measured stretch, itself no significant trend.
Not this whole stretch, just Panacea itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
