Analysis of Nd isotope, REE and oxygen isotope ratios on water samples across Fram Strait@en

The water masses passing the Fram Strait are mainly responsible for the exchange of heat and freshwater between the Nordic Seas and the Arctic Ocean (the Arctic Mediterranean, AM). Disentangling their exact sources, distribution and mixing, however, is complex. This work provides new insights based on a detailed geochemical tracer inventory including dissolved Nd isotope (e-Nd), rare earth element (REE) and stable oxygen isotope (d18O) data along a full water depth section across Fram Strait. […]流经弗拉姆海峡（Fram Strait）的水团，主要负责挪威海（Nordic Seas）与北冰洋（Arctic Ocean，亦称北极地中海，AM）之间的热量与淡水交换。然而，厘清这些水团的确切来源、分布与混合过程却颇具挑战性。本研究基于一套涵盖溶解态钕同位素（dissolved Nd isotope, e-Nd）、稀土元素（rare earth element, REE）与稳定氧同位素（stable oxygen isotope, d18O）的详尽地球化学示踪剂数据集，获取了横跨弗拉姆海峡的全水深断面实测数据，据此获得了全新的研究见解……
