Gardiner, OR Coastal Erosion Rate
What USGS measures 5.5 miles northwest of Gardiner, OR
Good news, and an honest one: USGS's data can't distinguish this stretch, 5.5 miles northwest of Gardiner, OR, from a flat trend. Whatever small movement it measured here is statistical noise, not a reliable direction, so none is claimed.
What "Gardiner" 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 Gardiner, OR, rather than showing one arbitrary line. Segment center: 43.80, -124.17. The survey behind it runs to 2002-2011, in USGS's Pacific Northwest 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.
Where this fits nationally
Averaging 108 separate transects produced this segment's rate, with 0% individually reading as erosion, rather than relying on any single survey line. Uncertainty on this specific number: 0.51 ft/yr either side. The unadjusted figure here, 0.35 ft/yr, would place it 982 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 2012-1008. For scale: Long Beach, CA, 764 miles away, ranks 1135 of 1211 nationally for growth, 1.31 ft/yr. 2.3 miles away, Gardiner, OR is the nearest other measured stretch: slight accretion (beach growing) at 0.82 ft/yr.
Not this whole stretch, just Gardiner itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
