Drillers Steve Cole, Justin Blouin, AJ Vecchiarelli, Beau Marshall and Matt Lyon hold the last core of the SUSTAIN drilling operation. At 10:30 am, September 4th, coring was completed. The drilling stopped at 354 m, corresponding to a vertical depth of 290 m. The feeder dike of the effusive vents of Surtur I was intersected at 343 m after drilling mostly through lapilli tuff. The final meter cored was again lapilli tuff, indicating that drilling traversed the dike. The drilling team deserves the highest praise for their dedication, enthusiasm and drive in bringing the drilling operation to such a grand finish. The efforts of the waterline workers, and the science team on Surtsey and Heimaey has been critical to the extraordinary success of the project.
