Full Record - Samples and analyses of sediment cores from Moutonnee, Ablation and Citadel Bastion Lakes, Antarctic Peninsula, 2001-2002

Samples and analyses of sediment cores from Moutonnee, Ablation and Citadel Bastion Lakes, Antarctic Peninsula, 2001-2002

GB/NERC/BAS/PDC/00544

Abstract:
Sediment cores were collected from the 3 sites (approx. 6m from Moutonnee Valley, 2.5m from Ablation Valley and 5m from Citadel Bastion on Alexander Island). They were analysed for physical property data including: magnetic susceptibility, wet weight, loss on ignition, grain size, isotopic content, bulk carbon, CHN, diatom content, forams, Authigenic carbonate, radiocarbon ages, Strontium and Neodymium content, major, trace and rare earth elements of sediments and clasts and clast lithological analysis. Analyses were carried out at Durham and Edinburgh with isotopic analysis conducted at NIGL (NERC Isotopic Geoscience Laboratory).
