Climate models for the Neogene suggest a permanent El Niño state with an enhanced variability. Proxy records of Neogene climate, however, usually resolve thousands of years only and little is known, therefore, with regard to real Neogene atmosphere dynamics. So far, only few multidecadal records from zooxanthellate corals (z-corals) of Neogene age are available to test climate model predictions (1, 2). With this new research, we produce seasonally resolved proxy records (δ18O, δ13C, Sr/Ca, Ba/Ca etc.) from Neogene z-corals and bivalves of the Caribbean region. In the present-day, this area is particularly sensitive to the AO/NAO/AMO and ENSO, and our data will allow tracking back in time the history of this type of atmospheric variability in relationship with the closure of the Panama strait. A second research application to be submitted in the near future will be designed to study the effects of sea strait closure on eastern Atlantic climate and neritic oceanography.

新近纪的气候模型表明，厄尔尼诺现象是一种永久性的状态，变异性增强。然而，新近纪气候的替代记录通常只能分辨数千年，因此，关于真正的新近纪大气动力学，人们知之甚少。到目前为止，只有很少的来自新近纪虫黄珊瑚(z珊瑚)的数十年记录可以用来检验气候模型的预测(1，2)。通过这项新的研究，我们产生了季节性解析的替代记录(δ18O，δ13C，锶/钙，巴/钙等)。来自加勒比海地区的新近纪Z珊瑚和双壳类。目前，这一地区对AO/NAO/AMO和ENSO特别敏感，我们的数据将使我们能够及时追踪与巴拿马海峡关闭有关的这类大气变化的历史。将在不久的将来提交的第二项研究申请将旨在研究关闭海峡对东大西洋气候和浅海海洋学的影响。
