Field Activity 2004-309-FA

Identifier 2004-309-FA
Purpose To collect vibracores
Location Delta National Wildlife Refuge, Louisiana
Summary During the summer of 2004, eight sediment vibracores were collected in the DNWR. Three of the vibracores were collected using the U.S.G.S. R/V G.K. Gilbert’s vibracoring system, which is capable of collecting cores up to 6.1 m in length. However, because of the shallow water over the delta, a shallow-draft aluminum boat was used to complete the vibracore field survey. Coring was accomplished using 9.1-m aluminum vibracore pipe and a modified Dreyer gasoline concrete vibrator.
Info derived photographed and sampled for grain-size analysis. Vibracores BBNWR-04 and 07 were subsampled within each sedimentary facies for cesium-isotope dating. Grain-size samples were collected within each sedimentary facies. Grain-size analyses were performed using a Coulter LS 200 particle-size analyzer that uses laser diffraction to measure the size distribution of particles from 0.4 µm to 2000 mm.
