Carbon and nitrogen content and stable isotope compositions from particulate organic matter samples from lagoon, river, and open ocean sites along the Alaska Beaufort Sea coast, 2018-ongoing

Multiple water types (river, lagoon, ocean) from the North Slope of Alaska and 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. Water 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 particulate organic carbon (POC) and particulate organic nitrogen (PON) content and stable isotopic composition.

博福特泻湖生态系统长期生态研究（Beaufort Lagoon Ecosystems LTER，简称BLE LTER）核心项目对取自阿拉斯加北坡及波弗特海近岸区域的多种水体类型（河流、泻湖、海洋）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。该项目在全面封冻期（4月）、融冰期（6月中旬至7月初）以及开阔水域期（7月下旬至8月）采集水样，并对水样的颗粒有机碳（particulate organic carbon, POC）、颗粒有机氮（particulate organic nitrogen, PON）含量与稳定同位素组成开展分析。
