Quogue, NY Coastal Erosion Rate

What USGS measures 0.7 miles south of Quogue, NY

No significant trend

Good news, and an honest one: USGS's data can't distinguish this stretch, 0.7 miles south of Quogue, NY, from a flat trend. Whatever small movement it measured here is statistical noise, not a reliable direction, so none is claimed.

The grain of this number

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 Quogue, NY, rather than showing one arbitrary line. Segment center: 40.81, -72.60. Survey years: 2007-2009, method LRR, from USGS's New England / Mid-Atlantic shoreline-change assessment. That's how current the data is here, real, but not a live feed, since a shoreline survey is a major undertaking, not an annual check-in.

Where this fits nationally

Averaging 90 separate transects produced this segment's rate, with 94% individually reading as erosion, rather than relying on any single survey line. Uncertainty on this specific number: 0.31 ft/yr either side. The unadjusted figure here, -0.28 ft/yr, would place it 414 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 2010-1119. Ocean City, NJ sits at national rank 1110 for growth (1.02 ft/yr), one reference point among the 1211 scored segments, 151 miles from here. 2.1 miles away, East Quogue, NY is the nearest other measured stretch: slight erosion at 0.32 ft/yr.

Not this whole stretch, just Quogue itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
