Average of parameters for the geographic clusters based on the environmental matrix.

Averaged values ± standard deviation of hydrographic/IOP parameters and geographic region for each of the clusters presented in Fig 4. Geographic regions acronyms: BG (Beaufort Gyre); EB (Eurasian Basin–Amundsen and Nansen basins); LS (Laptev Sea); LSS (Laptev Sea Shelf–Lena river influenced); TPD (Transpolar Drift).图4所示各聚类的水文参数/固有光学特性（Inherent Optical Properties，IOP）平均值±标准差，以及各聚类对应的地理区域。地理区域缩写说明：BG（波弗特海环流，Beaufort Gyre）；EB（欧亚海盆——阿蒙森海盆与南森海盆，Eurasian Basin–Amundsen and Nansen basins）；LS（拉普捷夫海，Laptev Sea）；LSS（受勒拿河影响的拉普捷夫海陆架，Laptev Sea Shelf–Lena river influenced）；TPD（跨极漂流，Transpolar Drift）。
