WebJun 24, 2024 · Here we use a new technique, GPS interferometric reflectometry, to estimate the rate of this process in the Mississippi Delta and the eastern margin of the North Sea. We show that the rate of shallow compaction is comparable to or larger than the rate of global SLR, adding 35% and 65%, respectively, to the rate of relative SLR by 2100. Key … WebJul 1, 2016 · GPS interferometric reflectometry is a new environmental sensing technique that can be used to measure near-surface soil moisture, snow depth, and vegetation water content variations. The spatial scale of this technique, ~1000 m 2, is intermediate to that of other in situ sensors (<1 m 2) and satellites (>100 km 2 ).
