Barview, OR Coastal Erosion Rate
Is the coast eroding 1.4 miles west of Barview, OR?
Good news, and an honest one: USGS's data can't distinguish this stretch, 1.4 miles west of Barview, OR, 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 Barview, OR, rather than showing one arbitrary line. Segment center: 43.35, -124.33. 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.
What backs this reading up
33 transects feed this segment's number; 33% of them individually measured retreat. Uncertainty on this specific number: 1.88 ft/yr either side. The unadjusted figure here, 0.33 ft/yr, would place it 972 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: East Atlantic Beach, NY, 2568 miles away, ranks 1172 of 1211 nationally for growth, 2.39 ft/yr. 1.2 miles up the coast, Barview, OR shows 2.33 ft/yr of accreting.
