Electron Probe Microanalyzer (EPMA) data from a selection of tephra occurrences drilled at IODP Sites 350-U1436 and 350-U1437. (NERC grant NE/M005240/1)
Many tephra layers were identified in sediment cores drilled during IODP Expedition 350. Here, 1092 glass shards from 76 tephra occurrences (layer or patch) were analysed using electron prob ...

Foraminifera-based data spanning several tephra horizons in cores from IODP Leg 350, sites U1436 and U1437 (NERC grant NE/M005232/1)
The dataset worksheet contains a list of core samples taken during IODP Exp 350 and foraminifera-based data for selected samples. The work was started with the aim of reconstructing palaeopr ...

Glass geochemical data of Late Quaternary tephra from Main Ethiopian Rift (NERC grant NE/L013533/1)
Glass major element geochemical data on Late Quaternary tephra deposits from the Main Ethiopian Rift volcanoes. These data were acquired using Electron Microprobe Analysis, and secondary sta ...

Grain Size data from a selection of tephra occurrences drilled at IODP Sites 350-U1436 and 350-U1437. (NERC grant NE/M005240/1)
120 samples of 57 tephra layers identified at IODP Expedition 350 sites (U1436 and U1437) were used in grain size analysis. Some layers have one grain size measurement, others have multiple ...

Tephra occurrences offshore Japan, collected from shipboard records of IODP, ODP and DSDP sediment cores. (NERC grant NE/I006125/1)
This MS Excel dataset contains tephra depth and age data from ocean drilling expeditions around Japan. IODP, ODP and DSDP shipboard core description records were examined for mentions of vol ...
