Sediment properties in shallow waters around Chandeleur Islands in 2015

Sediments were collected in conjunction with infauna sampling at the Chandeleur Islands in 2015 and analyzed for porosity of depth slices of 1 cm increments for the top 5 cm and 2 cm increments for 5-15 cm depth. C and N were measured using a Costech 4010 elemental combustion system, and data are given as total N (umol), total C (umol) and C:N ratio. Sediment grain size analysis was done using standard gravitational methods and is presented as % sand, silt, and clay. Samples were collected in shallow water (0.25-1 m depth) in Haledule beds and adjacent bare sediments.
