    This database is from series of laboratory experiments designed to explore the effect of hydrate cementaion on some sands. This dataset is part of NERC Arctic Landslide-Tsunami Project (http://arp.arctic.ac.uk/projects/landslide-tsunami/) and has been presented in International conference and Journal article (under review) namely, 1) Madhusudhan, B.N. and Clayton, C.R.I. (2016) Influence particle size on strength of gas hydrate cemented granular materials. Wuttke, F., Bauer, S. and Sanchez, M. (eds.) In Energy Geotechnics. CRC Press. 742 pp, pp. 445-449. (doi:10.1201/b21938-71). 2) Madhusudhan,B.N, Clayton, C.R.I. and Priest, J.A ‘1 The Effects of Hydrate on the Strength and Stiffness of some Sands’. Under-review in Journal of Geophysical Research – Solid Earth.

    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.
