Title: Yearly survey of barnacle settlement in mid-marsh and creekbank plots at GCE LTER study sites in October 2013
Abstract: To characterize spatial variation in barnacle recruitment within two zones in the salt marsh, the mid-marsh and creekbank, and across a gradient in salinity and distance to ocean, we deployed PVC poles to passive sample barnacle settlement. Eight poles were deployed between 4-5m apart in each marsh zone at each GCE LTER permanent monitoring site each Fall beginning in 2012. These poles were then collected the following Fall and all barnacle that settled on the poles were identified and counted on 50cm-long sections of the 8, 3/4" diameter PVC poles. Although a few other barnacle species are occur within this estuary, only Chlathamus fragilis settled on the poles.
