Barnacle Dynamics: Point Intercept Surveys - BC Central Coast - 2016-2018

The barnacle dynamics dataset is a component of the Hakai Institute’s Nearshore research and monitoring program, designed to capture change in rocky intertidal habitats. The overarching objective of Hakai Nearshore research is to investigate the role of habitats and their associated communities, in the face of stress and disturbances from global climate change and local coastal perturbations.

The barnacle community was assessed from 2016-2018 at three coastal sites along the northwest edge of Calvert Island on the Central Coast of British Columbia. All three sites were exposed rocky shorelines with contiguous zones of substrate dominated by species of barnacle. The abundance and diversity of the barnacle species within these zones was surveyed using point-intercepts within permanent plots. The sites were surveyed on an approximately monthly basis from May-September, and two winter surveys in November and February. Six surveys were conducted in 2018, 5 in 2017, and 3 in 2016.

This data package is freely available to everyone, following the principles of equitable access and benefit sharing. However, we expect all data users to give attribution to the data providers (read our data license) and the use of these data should happen in the light of fair use, i.e.: 1) respect the data providers, and provide helpful feedback on data quality, and 2) communicate and/or collaborate with the providers if you are considering using this dataset for manuscripts or other forms of reporting.

藤壶动态数据集（barnacle dynamics dataset）是哈科研究所（Hakai Institute）近岸研究与监测计划的组成部分，旨在记录岩相潮间带生境（rocky intertidal habitats）的变化。哈科研究所近岸研究的核心目标，是探究在全球气候变化与本地海岸扰动带来的压力和干扰下，各类生境及其伴生群落所发挥的作用。

2016至2018年间，研究团队在不列颠哥伦比亚省（British Columbia）中部海岸的卡尔弗特岛（Calvert Island）西北沿岸的三个沿海站点开展了藤壶群落评估。三个站点均为开阔暴露型岩质岸线，区域内底物连续分布且优势类群为藤壶物种。研究通过永久样地（permanent plots）内的点截样法（point-intercept），对该区域内藤壶物种的丰度与多样性进行调查。调查周期为每年5月至9月，约每月开展1次，另于每年11月与2月各开展1次冬季调查。2018年共完成6次调查，2017年5次，2016年3次。
