Meroplankton in Isfjorden 2016 to 2017

## Methods ### Study area This dataset is the result of a sampling program in Isfjorden on the west coast of Spitsbergen, Svalbard. ### Time coverage The sampling was conducted in 2016 and 2017, with one sampling per season; summer and autumn in 2016 and winter and spring in 2017. ### Sampling 50 sea water samples were collected at two stations named "n1" and "s2". On each sampling date three sampling protocols were used: - a fine net deployed horizontally by a diver (100 µm mesh) - a specialized water pump (hoover/vacuum, 100 µm) deployed at a certain depth - vertical plankton net tows (WP2-net, 65 µm). Both the diver's net and vacuum pump sampled from 6 and 12 meters depth at each station, while the WP2-net sampled from 50 to 0 meters and from 12 to 0 meters depth. For station "s2", the sampling at 6 meters with a diver's net and vacuum pump was carried out in the autumn of 2017 and not together with the other sampling that occurred in the autumn of 2016. ## Taxonomy The dataset was analysed using image analysis software (Ecotaxa) with subsequent expert validation. ## Data ## This dataset is built using a [fully automated processing pipeline](https://github.com/akvaplan-niva/gbif-no-darwin-core/blob/main/bin/ecotaxa-pipeline), using the [ecotaxa-occurrences](https://github.com/akvaplan-niva/ecotaxa-darwin-core#ecotaxa-occurrences) ## Processing https://doi.org/10.5281/zenodo.4700253 This dataset contains two Darwin Core distributions - dwc-ndjson: Newline separated JSON (NDJSON) - dwc-a: Darwin Core archive (TSV/XML) command line tool.

### 方法
#### 研究区域
本数据集为斯瓦尔巴群岛斯匹次卑尔根岛西海岸伊萨福德湾（Isfjorden）海域采样项目的成果。
#### 时间覆盖范围
采样工作于2016年与2017年开展，每季采样一次：2016年完成夏季与秋季采样，2017年完成冬季与春季采样。
#### 采样方案
在编号为"n1"与"s2"的两个站位共采集50份海水样本。每次采样均采用三种采样流程：
- 潜水员水平布设的细网（孔径100 µm）
- 特定深度布设的专用水泵（抽吸式/真空式，孔径100 µm）
- 垂直浮游生物网拖网（WP2-net，孔径65 µm）
潜水员布设的细网与真空水泵均在每个站位的6米与12米深度处采样，而WP2型网的采样深度范围分别为50米至表层（0米）以及12米至表层。
针对站位"s2"，采用潜水员细网与真空水泵在6米深度的采样仅于2017年秋季开展，未与2016年秋季开展的其他采样同步进行。
#### 分类学分析
本数据集通过图像分析软件（Ecotaxa）完成分析，并经专家后续验证。
#### 数据说明
本数据集基于[全自动处理流水线](https://github.com/akvaplan-niva/gbif-no-darwin-core/blob/main/bin/ecotaxa-pipeline)构建，采用了[ecotaxa-occurrences](https://github.com/akvaplan-niva/ecotaxa-darwin-core#ecotaxa-occurrences)工具。
