DecLakes will provide six well-dated high-resolution records of the oxygen-isotope composition of past precipitation derived from ostracods in the profundal lake sediments from the Northern, Western and Southern margin of the Alps and from North-eastern Poland. The wide spatial distribution will allow to decipher in particular regional variations of past climate variability. A network of highly experienced research gropus of which each will apply their specific knowledge in isotope analyses, sedimentology and palaeoecology to all sediment cores guarantees a high degree of comparability of the individual data sets in terms of dating, analytical standards and data quality. These data sets will be used for data-model-comparision applying a hierarchy of models equipped with the explicit modelling of water stable isotopes. The study concentrates on three time windows: (1) The last 1.000 years, (2) the period around the prominent cold phase at 8.200 BR, and, (3) the Lateglacial with a special focus on the rapid high-amplitude changes. The expected outcome of the project will be a spatial view of decadal to centennial climate variability in Europe which will be used to better understand prevailing forcing mechanisms.

DecLakes将提供六个日期明确的高分辨率记录，记录阿尔卑斯山北方、西部和南部边缘以及波兰东北部深湖沉积物中介形虫产生的过去降水的氧同位素组成。这种广泛的空间分布将使我们能够特别解读过去气候变异的区域变化。一个由经验丰富的研究小组组成的网络-每个小组将把其在同位素分析、沉积学和古生态学方面的专门知识应用于所有沉积物岩心-保证了各个数据集在测年、分析标准和数据质量方面的高度可比性。这些数据集将用于数据-模型-比较，采用配备有水稳定同位素明确建模的模型层次。研究集中在三个时间窗口：（1）过去1.000年，（2）在8.200 BR的显著冷相周围的时期，（3）晚冰期，特别关注快速的高振幅变化。该项目的预期成果将是欧洲十年至百年气候变率的空间视图，将用于更好地了解主要的强迫机制。
