title: Dissolved Fe in soil pore water, 2011

description: Soil pore water was collected from 16 drained thaw lake basins near Barrow, AK and analyzed colorimetrically for Fe(II) and Fe(III). Three to five basins of each age class (as determined by Hinkel and others) were chosen. Transects were established in each basin (most were 30 m long, except the plots established in 2010, which were up to 72 m long). Samples (generally five per transect) were collected into vacutainers from Rhizon soil water samplers, preserved with a drop of HCl, and analyzed using 1,10-phenanthroline, with and without ascorbate for total Fe and Fe(II), respectively. Fe(III) was determined by difference.

title: Ground Penetrating Radar of drained thaw lake basins

description: GPR surveys were conducted using a Pulse Ekko Pro system, manufactured by Sensors and Software, with 500 MHz antennae. Surface common-offset measurements were collected using a trace spacing of 0.05 m and 16 stacks per trace. Transects were run over frozen soil in early June, 2010. Snow was removed to improve signal penetration. Based on common midpoint soundings, the velocity was 0.12 m/ns for the Old transects and 0.10 to 0.05 m/ns for the Young transects.
