Mesozooplankton abundance data from the fjord branch Kapisigdlit located in the Godthaabsfjord system, West Greenland, 2010

Sampling was conducted from March 24 to August 5 2010, in the fjord branch Kapisigdlit located in the inner part of the Godthåbsfjord system, West Greenland. The vessel "Lille Masik" was used during all cruises except on June 17-18 where sampling was done from RV Dana (National Institute for Aquatic Resources, Denmark). A total of 15 cruises (of 1-2 days duration) 7-10 days apart was carried out along a transect composed of 6 stations (St.), spanning the length of the 26 km long fjord branch. St. 1 was located at the mouth of the fjord branch and St. 6 was located at the end of the fjord branch, in the middle of a shallower inner creek . St. 1-4 was covering deeper parts of the fjord, and St. 5 was located on the slope leading up to the shallow inner creek. Mesozooplankton was sampled by vertical net tows using a Hydrobios Multinet (type Mini) equipped with a flow meter and 50 µm mesh nets or a WP-2 net 50 µm mesh size equipped with a non-filtering cod-end. Sampling was conducted at various times of day at the different stations. The nets were hauled with a speed of 0.2-0.3 m s**-1 from 100, 75 and 50 m depth to the surface at St. 2 + 4, 5 and 6, respectively. The content was immediately preserved in buffered formalin (4% final concentration). All samples were analyzed in the Plankton sorting and identification center in Szczecin (www.nmfri.gdynia.pl). Samples containing high numbers of zooplankton were split into subsamples. All copepods and other zooplankton were identified down to lowest possible taxonomic level (approx. 400 per sample), length measured and counted. Copepods were sorted into development stages (nauplii stage 1 - copepodite stage 6) using morphological features and sizes, and up to 10 individuals of each stage was length measured.

采样工作于2010年3月24日至8月5日在西格陵兰戈特霍布峡湾（Godthåbsfjord）系统内部的卡皮西格利特峡湾支湾（Kapisigdlit）开展。所有航次均使用“利勒·马西克”号（Lille Masik）作业，仅2010年6月17日至18日航次除外，该次采样由丹麦国家水产资源研究所的“达纳”号科考船（RV Dana）完成。
本研究共开展15个航次，单个航次时长1至2天，航次间隔7至10天；采样断面由6个站位（St.）组成，覆盖这条26千米长的峡湾支湾全程。站位1位于峡湾支湾的入口处，站位6位于峡湾支湾末端的一处较浅内湾中部。站位1至4覆盖峡湾的较深水域，站位5位于通往浅内湾的斜坡区域。
中型浮游动物（Mesozooplankton）采用垂直拖网方式采集：使用配备流量计的Hydrobios多栏微型浮游生物网（Hydrobios Multinet Mini），网孔孔径为50 μm；或使用网孔孔径50 μm的WP-2浮游生物网（WP-2 net），搭配非过滤式网囊（non-filtering cod-end）。不同站位的采样时间覆盖全天各时段。
起网速度为0.2~0.3 m·s⁻¹，其中站位2和4的起网深度为100米、站位5为75米、站位6为50米，均拖至表层。采集的样品立即用缓冲福尔马林溶液固定（终浓度为4%）。
所有样品均在什切青的浮游生物分选与鉴定中心完成分析（网址：www.nmfri.gdynia.pl）。对于浮游动物个体数量较多的样品，会进行分样处理。
所有桡足类（copepods）与其他浮游动物均鉴定至尽可能低的分类阶元，每份样品约鉴定400个个体，并测量其体长、统计个体数量。桡足类将根据形态特征与体长划分为发育阶段（从无节幼体1期（nauplii stage 1）至桡足幼体6期（copepodite stage 6）），并对每个发育阶段的至多10个个体测量体长。
