Statement

The cores were extracted on board the JOIDES Resolution in April and May 2014. Dr E John selected a 2x2 cm sample over selected intervals spanning both mafic and felsic tephra layers in cores U1437B and U1436A. At Cardiff University, selected samples were subjected to the following procedure: 1. Samples were soaked in distilled water overnight and gently disaggregated using fingertips. All samples were easy to disaggregate and did not require the use of detergent. 2. Samples were then wet-sieved through a 63-µm mesh and the coarse fraction was dried in an oven at 60°C, and weighed. 3. The sample was then dry-sieved to extract the 250-355 µm size fraction, which was used for foraminifera picking. 4. In each examined split, specimens of G. ruber, O. umbonatus, Uvigerina spp., and Cibicidoides spp. were picked using a fine paintbrush and then stored in micropalaeontological slides. 5. Those required for analysis were ultrasonically-cleaned and split open using a cleaned glass slide. Any adhering organic matter or silicate was removed using a fine paintbrush. The samples were then ultrasonically cleaned in 18ΩM water and left to dry in polypropylene microcentrifuge tubes. 6. Samples were then weighed into tin cups and placed into acid-cleaned tubes for stable isotope analysis which was performed on a Thermo MAT 253 with Kiel IV carbonate preparation device.
