Gulf Park Estates, MS Coastal Erosion Rate
Shoreline change 9 miles south of Gulf Park Estates, MS
Good news, and an honest one: USGS's data can't distinguish this stretch, 9 miles south of Gulf Park Estates, MS, from a flat trend. Whatever small movement it measured here is statistical noise, not a reliable direction, so none is claimed.
What this reading actually covers
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 Gulf Park Estates, MS, rather than showing one arbitrary line. Segment center: 30.25, -88.73. USGS's Gulf of Mexico assessment last surveyed this stretch through 2001, computing the rate with its LRR method. Other US regions were surveyed in different years, sometimes decades apart, so this page states its own rather than implying one national vintage.
What backs this reading up
2 transects feed this segment's number; 0% of them individually measured retreat. Uncertainty on this specific number: 1.16 ft/yr either side. The unadjusted figure here, 0.34 ft/yr, would place it 977 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. Dover Beaches South, NJ sits at national rank 994 for growth (0.4 ft/yr), one reference point among the 1211 scored segments, 1062 miles from here. 1.6 miles up the coast, Gulf Park Estates, MS shows the same lack of a significant trend.
