Mesozooplankton biomass data from the Kapisigdlit an inner fjord branch of 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（Kapisigdlit）峡湾支湾开展。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日的航次除外，当日采样由丹麦国家水生资源研究所的"达纳"号科考船（RV Dana）完成。本次研究共开展15个航次，每个航次持续1至2天，航次间隔7至10天，沿由6个站位（Stations，缩写St.）组成的断面开展作业，覆盖这条全长26千米的峡湾支湾。站位1位于峡湾支湾口，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覆盖峡湾的较深区域，站位5则位于通往该浅海内湾的斜坡处。中型浮游动物（Mesozooplankton）采用垂直拖网法采集，使用配备流量计与50微米网孔的Hydrobios微型多网（Hydrobios Multinet Mini型），或配备非过滤拖网网囊的50微米网孔WP-2型拖网。不同站位的采样在一天中的不同时段进行。拖网收网速度为0.2至0.3米每秒，其中站位2与4的收网深度为从100米至表层，站位5为从75米至表层，站位6为从50米至表层。采集的样品立即用缓冲福尔马林溶液固定，最终浓度为4%。所有样品均在什切青浮游生物分选与鉴定中心（www.nmfri.gdynia.pl）进行分析。对于浮游动物数量较多的样品，会进行分样处理。所有桡足类与其他浮游动物均鉴定至尽可能低的分类学阶元（每份样品约鉴定400个个体），并测量其体长、统计个体数量。桡足类依据形态特征与体长分为不同发育阶段（从无节幼体1期至桡足幼体6期），并对每个阶段的至多10个个体进行体长测量。
