Replication Data for: Subtidal and Intertidal Microplastics, Saint John Harbour, New Brunswick (CC BY 4.0)

In October 2018, subtidal and intertidal sediment samples were collected across the inner and outer Saint John Harbour and analyzed for microplastics by two University of New Brunswick researchers, Krista Beardy and Dr. Heather Hunt. The subtidal samples were collected using a 0.1〖 m〗^2 Smith McIntyre grab (SMG) sampler, while the intertidal samples were collected using a metal, paint-free trowel. Lab analysis was conducted as per the protocols developed by Krista Beardy and involved two extractions of microplastics; the first extraction used a 10% potassium hydroxide (KOH) solution and the second extraction used a concentrated zinc chloride (ZnCl2) solution. Environment and Climate Change Canada’s Atlantic Ecosystems Initiatives program provided funding to support this work; COINAtlantic (coinatlantic.ca) collaborated with research partners to make data publicly available under the FAIR data guiding principles.

2018年10月，研究者于圣约翰港（Saint John Harbour）内外区域采集潮下带与潮间带沉积物样本，并由新不伦瑞克大学（University of New Brunswick）的克里斯塔·比迪与希瑟·亨特博士两名科研人员针对样本中的微塑料（microplastics）开展分析。其中潮下带样本采用面积为0.1平方米的Smith McIntyre采泥器（Smith McIntyre grab, SMG）采集，潮间带样本则使用无漆金属抹刀采集。实验室分析遵循克里斯塔·比迪制定的实验规程，包含两步微塑料提取流程：第一步使用10%氢氧化钾（potassium hydroxide, KOH）溶液，第二步使用高浓度氯化锌（zinc chloride, ZnCl₂）溶液。加拿大环境与气候变化部大西洋生态系统倡议项目为本次研究提供经费支持；COINAtlantic（coinatlantic.ca）与各合作研究伙伴协作，依据FAIR数据（FAIR data）指导原则将研究数据对外公开。
