Particulate Organic Matter composition in and around macroalgal beds in Kongsfjorden, Arctic

This dataset provides the composition and distribution of Particulate Organic Matter (POM) within Kongsfjorden, Arctic, focusing on the influence of macroalgal beds across twelve distinct sampling stations. These stations were categorized based on their proximity to macroalgal-dominated sites (MDS), and locations at distances of 500 m and 1500 m away. It includes hydrological parameters including salinity, temperature, turbidity, chlorophyll a, and nutrients like nitrate, phosphate, and nitrite. The dataset also contain detailed information of Particulate Organic Carbon (POC), Particulate Nitrogen (PN), and stable isotopes (δ¹³C and δ¹⁵N), alongwith particultae carbohydrates (PCHO), proteins (PPRT), and lipids (PLIP). This dataset also include specific monosaccharide and amino acid compositions (in both µg L⁻¹ and mol%), and assessed the nutritional quality of the organic matter by calculating biopolymeric carbon (BPC) and the percentage of labile versus refractory material.本数据集涵盖北极孔斯夫尔登峡湾（Kongsfjorden）内颗粒有机质（Particulate Organic Matter, POM）的组成与分布特征，重点聚焦大型藻床对其的影响，共设置12个独立采样站位。这些站位依据其与大型藻主导区域（macroalgal-dominated sites, MDS）的相对距离进行分类，分别位于大型藻主导区域、以及距离该区域500米和1500米的位置。数据集包含多项水文参数，如盐度、温度、浊度、叶绿素a，以及硝酸盐、磷酸盐、亚硝酸盐等营养盐指标。此外，数据集还包含颗粒有机碳（Particulate Organic Carbon, POC）、颗粒氮（Particulate Nitrogen, PN）、稳定同位素（δ¹³C与δ¹⁵N）的详细信息，以及颗粒态碳水化合物（particulate carbohydrates, PCHO）、蛋白质（proteins, PPRT）与脂类（lipids, PLIP）的相关数据。本数据集还涵盖了特定单糖与氨基酸组成数据（单位涵盖µg L⁻¹与mol%两种形式），并通过计算生物聚合物碳（biopolymeric carbon, BPC）以及易降解与难降解有机质占比，评估了该区域有机质的营养品质。
