Carbon and nitrogen content and stable isotope composition from sediment organic matter from lagoon sites along the Alaska Beaufort Sea coast, 2018-ongoing

Multiple sediment samples from lagoons along the nearshore Beaufort Sea are sampled seasonally by the Beaufort Lagoon Ecosystems LTER (BLE LTER) Core Program to investigate biogeochemical linkages between terrestrial, lagoon, and open ocean ecosystems. Sediment samples are collected during full ice cover (April), ice break-up (mid-June to early July), and open water (late July and August) periods, and analyzed for carbon and nitrogen content and stable isotopic composition.

波弗特海近岸泻湖的多份沉积物样品，由波弗特泻湖生态系统长期生态研究（Beaufort Lagoon Ecosystems LTER, BLE LTER）核心项目开展季节性采样，以探究陆地、泻湖与开阔海洋生态系统之间的生物地球化学联系。该项目会在海冰完全封冻期（4月）、冰消期（6月中旬至7月初）以及开阔水域期（7月下旬至8月）采集沉积物样品，并对样品的碳、氮含量及稳定同位素组成进行分析。
