Pensacola Station, FL Coastal Erosion Rate
What USGS measures 4.9 miles west of Pensacola Station, FL
Nothing alarming measured 4.9 miles west of Pensacola Station, FL: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
The grain of this number
Pensacola Station, FL is the nearest named place, 4.9 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 30.33, -87.39. 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.
What backs this reading up
This reading comes from 77 individual transects averaged together, 100% of which measured erosion rather than growth. USGS's confidence interval here is ±0.48 ft/yr. The unadjusted figure here, -0.43 ft/yr, would place it 333 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. Rank 1129 nationally for growth belongs to Provincetown, MA, 1250 miles from this stretch, measured at 1.26 ft/yr. 1.5 miles up the coast, Pensacola Station, FL shows the same lack of a significant trend.
