Brunswick, ME Coastal Erosion Rate
What USGS measures 12.9 miles south of Brunswick, ME
12.9 miles south of Brunswick, ME: USGS's transects didn't pick up a trend here that beats the survey's own uncertainty. That's the majority case nationally, and for this stretch specifically it means the coast is holding, not that the data failed to find anything.
What "Brunswick" means on this page
This is a roughly 3.5-mile stretch of coast, not one address or parcel - USGS's own transects run every few hundred feet, but that's finer than any one property needs, so this page reports the stretch nearest Brunswick, ME. Centered near 43.72°N, 69.84°W. 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.
What backs this reading up
Averaging 13 separate transects produced this segment's rate, with 62% individually reading as erosion, rather than relying on any single survey line. Uncertainty on this specific number: 0.08 ft/yr either side. Taken at face value, this segment's raw -0.03 ft/yr reading would land it 741 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2010-1119. West Sayville, NY sits at national rank 1057 for growth (0.66 ft/yr), one reference point among the 1211 scored segments, 267 miles from here. Brunswick, ME, 1.2 miles off, is the adjacent measured stretch, itself no significant trend.
