QEMSCAN(R) analyses on sediments recovered during the IODP Expeditions 372 and 375, Hikurangi Margin (New Zealand) (NERC grant NE/R016615/1)
The data include: 1. Excell spreadsheets from Sites U1517-C; U1518-f; U1519-C. Each spreadsheet contains detailed mineralogical information aquired with QEMSCAN®. 2. QEMSCAN-50 and QEMSCAN-4 images of the analysed samples. 3. Images (png files) of the sediment cores acquired during the IODP Expeditions. 4. A report on the characterisation of gas hydrate bearing sediments at site U1517, by integrating QEMSCAN, core, LWD, and seismic observations.

Data Quality
The bottom-hole assembly for LWD data was composed of 5 Schlumberger tools (NeoScope, SonicScope, TeleScope, proVISION, and geoVISION). The cores used in this study were recovered along hole U1517-C, U1518-F, and U1519-C. Chlorinity measurements were carried out on 75 whole-round samples. The interstitial water samples were carefully squeezed and filtered onboard, and analysed, following standard IODP protocols . Twenty 10 cm3 cylinder samples (7-U1517; 3-U1518; 4-U1519) have been acquired onboard for post-cruise QEMSCAN® analyses. The samples were prepared for QEMSCAN® analysis by mixing the material with Struers Epofix resin to create an SEM puck, curing under pressure, and grinding and polishing to 3?m grade to reveal grain centres. Finally, the pucks were carbon coated, and analysed by Rocktype Ltd on a Thermo Fisher Scientific QEMSCAN® Extreme at 15kV.
