Core-Based SCB Fracture of Aligned First-Year Sea Ice (Phase VI)

Abstract

In conjunction with Phase VI of the large-scale in-situ fracture test program undertaken during the Office of Naval Research (ONR) Sea Ice Mechanics Initiative (SIMI) project, three full-depth cores were collected from the first-year sea-ice sheet near Point Barrow, Alaska, and shipped back to Clarkson University for further analysis. A detailed study of the ice fabric at the site revealed that there was a very strong horizontal
