Biofouling data from underwater surveys of commercial ships in Canada
收藏资源简介:
Ship biofouling is a major vector for the introduction and spread of harmful marine species globally. Comprehensive underwater sampling and video recording of ship hulls was conducted to assess biofouling extent (percent cover, total abundance and species richness) on a subset of ships arriving to Canadian waters. The dataset includes underwater biofouling assessments from 53 commercial ships arriving at Halifax, Nova Scotia (20 international ships), Vancouver, British Columbia (20 international ships) during 2007–2009, and Churchill, Manitoba (11 international and 2 domestic ships) in 2010–2011. Potential explanatory variables in the dataset include ship size, typical sailing speed, port residence time, age of antifouling coating system and travel history (number of biogeographic realms visisted, and average, minimum and maximum port latititude).
船舶生物污损是全球范围内有害海洋物种引入与扩散的主要传播媒介。本研究针对抵达加拿大水域的部分船舶开展全方位水下采样与船体视频录制,以评估其生物污损程度——包括覆盖占比、总丰度与物种丰富度。本数据集涵盖2007至2009年间抵达新斯科舍省哈利法克斯港(20艘国际船舶)、不列颠哥伦比亚省温哥华港(20艘国际船舶),以及2010至2011年间抵达马尼托巴省丘吉尔港(11艘国际船舶与2艘国内船舶)的53艘商业船舶的水下生物污损评估数据。数据集内的潜在解释变量包含船舶尺寸、常规航行速度、港口停留时长、防污涂层系统使用年限,以及航行历史:涵盖途经的生物地理分区数量,以及港口纬度的平均值、最小值与最大值。
