In summer 2017, the ICDP SUSTAIN project (Surtsey Underwater volcanic System for Thermophiles, Alteration processes and INnovative concretes), drilled three cored boreholes through Surtsey next to a 1979 cored borehole.\u00a0 An Atlas Copco CS1000 drill rig, whose components were transported by helicopter to Surtsey and re-assembled on site, acheived the drilling through the still hot volcano. A first vertical borehole, SE-02a, was cored in HQ diameter to 152 meters below surface (m b.s.) August 7-16. It was terminated due to borehole collapse. A second vertical (SE-02b) cored borehole was then drilled in HQ diameter to 192 m August 19-26. A geophysical borehole log of SE-02b was performed August 26. The anodized NQ-sized aluminum tubing of the Surtsey Subsurface Observatory was installed in SE-02b to 181 m depth on August 27. A third borehole, SE-03, angled 35\u00b0 from vertical and directed 264\u00b0, was drilled from August 28 to September 4 and reached a measured depth of 354 m (~290 m vertical depth) under the eastern crater. The core is HQ diameter to a measured depth of 213 m and NQ diameter from 213-354 m measured depth. The core traverses the deep conduit and intrusions of the volcano to a total vertical depth of 290 m b.s. Seawater drilling fluid for boreholes SE-02a and SE-02b was filtered and doubly UV-sterilized at the drill site. No mud products were employed while coring SE-02a, while small amounts of attapulgite mud were used in SE-02b and SE-03. Core samples for geochemical analyses of pore water and microbiological investigations were collected\u00a0 from all three boreholes. About 650 m of core was transported by helicopter to Heimaey, 18 km northeast of Surtsey, to a processing laboratory where the core was scanned, documented, and described. Additional core processing has taken place at the N\u00e1tt\u00farufraedistofnun \u00cdslands, the Icelandic Institute of Natural History in Gardabaer, where both the 1979 and 2017 cores are stored.<\/p>\n
