Beware: measuring beach erosion with 2-D profiles can yield spurious results

Why is Ethan so happy?  Well, he just published a new paper in Earth Surface Processes and Landforms entitled, “Evaluating proxies for estimating subaerial beach volume change across increasing time scales and various morphologies“.  In the paper, Ethan critically evaluates … Continue reading

Using a Quadcopter/GoPro combo to measure morphologic change from above

In the past we have relied on aerial photography when measuring the morphology of washover fans. These fans are constantly changing shape, but we aren’t able to document these changes because images taken from a plane are only collected every couple … Continue reading

Where do coastlines stabilize following rapid retreat?

Bayhead deltas are located where rivers flow into estuaries.  They have broad low-elevation plains that are sensitive to small increases in the rate of sea-level rise.  In the past, when sea level was rising at a rate of 1 m … Continue reading

Coring backbarrier marshes to measure carbon storage

Island overwash forms new intertidal substrate (washover fans) for saltmarsh colonization.  As a barrier island moves landward in response to sea-level rise, that marsh sediment will eventually be eroded on the shoreface.  To develop coastal carbon budgets, it is important … Continue reading

IE class verifies Walther’s Law in the field

The Institute for the Environment (IE) class is learning about coastal geology this week by experiencing it first hand.  Walther’s Law tells us that the vertical succession of facies reflects lateral changes in environment.  That concept is an important part of … Continue reading
