Macrobenthic data of Rijpfjorden, Svalbard

The aim of this study was to monitor the temporal changes of the macrobenthos in Rijpfjorden (Svalbard, Arctic Ocean). This dataset contains abundance data of benthic macrofauna collected during five cruises to Rijpfjorden between late July and early September in 2003, 2007, 2010, 2013 and 2017. During each cruise, the seafloor of four stations (‘Inner Rijpfjorden’ (IR), ‘Middle Rijpfjorden’ (MR), ‘Outer Rijpfjorden’ (OR) and ‘Rijpfjorden North’ (RN)) was sampled with three deployments of a Van Veen grab (0.1 m2). The sediment was sieved over a 0.5 mm mesh and fauna was preserved in 4% buffered formaldehyde solution. Identifcation was carried out to the lowest possible taxonomic level.This dataset is in a multi-sheet format and quality-controlled by CRITTERBASE (https://critterbase.awi.de/#qc).

本研究旨在监测北冰洋（Arctic Ocean）斯瓦尔巴群岛（Svalbard）赖普峡湾（Rijpfjorden）的大型底栖生物（macrobenthos）时间变化。本数据集包含2003、2007、2010、2013及2017年7月末至9月初五次赴赖普峡湾航次采集的大型底栖动物（benthic macrofauna）丰度数据。每次航次均对四个站位——“赖普峡湾内湾（Inner Rijpfjorden, IR）”、“赖普峡湾中湾（Middle Rijpfjorden, MR）”、“赖普峡湾外湾（Outer Rijpfjorden, OR）”与“赖普峡湾北部（Rijpfjorden North, RN）”的海底进行采样，采用范维恩采泥器（Van Veen grab）进行三次部署，单次采样面积为0.1平方米。沉积物经0.5毫米孔径筛网筛分后，将底栖动物标本保存于4%缓冲甲醛溶液中。所有标本均尽可能鉴定至最低分类阶元。本数据集采用多工作表格式，已由CRITTERBASE（https://critterbase.awi.de/#qc）完成质量控制。
