The view of a generally warm-equable Early Cretaceous greenhouse world is questioned by a rather differentiated climatic scenario with cold snaps, possibly even causing polar ice caps. These contradictory interpretations are partly caused by a lack of data from the high latitudes which should be more sensitive to climatic changes. We therefore propose a multi-proxy approach based in the high latitudes (NE Greenland) to better understand the biotic, palaeoclimatic and palaeoceanographic evolution of the Early Cretaceous (Ryazanian – Barremian). Based on a biostratigraphic zonation (ammonites) we intend to a) establish a detailed multistratigraphic scheme for the Boreal-Arctic based on calcareous nannofossils, ammonites and strontium isotopy, which can be tied into the Tethyan succession, b) reconstruct changes of surface water conditions by evaluating calcareous nannofossil assemblages ecologically, c) use microfloras (calcareous nannofossils) and macrofaunas (ammonites, belemnites) to test the hypothesis of a proto-Golf stream, d) interpret the Ryazanian – Barremian interval of NE Greenland with respect to the enigma of high latitudinal carbonates.

一个相当差异化的杂种场景和冷a子，甚至可能导致极地冰盖，对普遍耐热的早白垩纪温室世界的看法受到了质疑。这些矛盾的解释部分是由于缺乏高纬度的数据引起的，这些数据应该对杂种变化更敏感。因此，我们提出了一种基于高纬度（NE Greenland）的多种方法，以更好地了解早期白垩纪早期（Ryazanian - Barremian）的生物，古气候和古生物学演变。 Based on a biostratographic zone (ammonites) we intend to a) establish a detailed multistratigraphic scheme for the Boreal-Arctic based on calcareous nannofossils, ammonites and strontium isotopy, which can be tied into the Tethyan success, b) reconstruct changes of surface water conditions by evaluating calcareous nannofossil assemblages ecologically, c) use microfloras (calcareous Nannannosils）和Macrofaunas（Ammonites，belemnites）测试原始高尔夫流的假设，d）解释NE Greenland的Ryazanian-Barremian间隔相对于高纬度碳酸盐的谜团。
