Abstract:

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.

Purpose:

For comparison with infaunal samples.

Data Parameters and Units:

Date (MM/HH/YYYY), Latitude (decimal degree), Longitude (decimal degree), Sample ID: station (A, B, C1, C2) and habitat (Open, Halodule, Thalassia, Marsh), Depth(cm, at the bottom of a slice. Slices are in 1 cm increments to 5 cm depth and 2 cm increments at 5-15 cm depth), Porosity (% water by weight), C:N: ratio of total Carbon to total Nitrogen (both in umol), Umol C (umol carbon), Umol N (umol nitrogen), %sand (% of sand by weight in total weight), %silt (% of silt by weight in total weight), %clay (% of clay by weight in total weight), %mud (% of mud, calculated as the sum of silt and clay)
