This dissertation improvement grant project will test hypotheses regarding the effects of the Little Ice Age cold period on Icelandic settlements using archaeological data, animal and fish bones, as well as marine molluscs. A baseline study will be made of stable carbon and oxygen isotopes and cadmium/calcium ratios in shells reflective of changes in local water temperatures and salinity in the North Atlantic. These studies are expected to provide climatic data of direct relevance to questions of economic change on Iceland and contribute to current research on global climate change.

这篇论文的改善赠款项目将使用考古数据、动物和鱼的骨骼以及海洋软体动物来检验关于小冰期冷期对冰岛定居点的影响的假说。将对贝壳中稳定的碳和氧同位素以及反映北大西洋当地水温和盐度变化的镉/钙比进行基线研究。预计这些研究将提供与冰岛经济变化问题直接相关的气候数据，并有助于目前对全球气候变化的研究。
