在冰川覆盖的南开普峡湾中发现的硝酸盐和硅酸盐浓度明显高于加拿大北极地区未冰川覆盖的格里斯峡湾或邻近的琼斯海峡。未发现磷酸盐浓度存在显着差异。冰川活动显然增加了那些对北极浮游植物需求最关键限制的营养物质的浓度。
Significantly higher concentrations of nitrate and silicate were found in glaciated South Cape Fiord than in unglaciated Grise Fiord, in the Canadian Arctic, or in adjacent Jones Sound. No significant differences in phosphate concentrations were found. Glacial activity apparently enriches the concentrations of those nutrients most critically limiting for arctic phytoplankton requirements.
