Growth rate of Peyssonnelid Algal Crusts at two sites and depths in Great Lameshur Bay, St. John, USVI as recorded in August 2019 and January 2020
收藏资源简介：
<p>Replicate: Replicate number (1 to 80) is the unique identification for each individual margin of PAC that was tagged between August 2019 and January 2020 in order to measure the growth rate of PAC.</p> <p>Site: The two sites within Lameshur Bay, St. John, USVI where margins of PAC were tagged to determine growth rate of PAC, and whether it varied between sites (Cabritte Horn, Tektite).</p> <p>Depth: Depth in meters (either 3 or 9 m) at the site where tags were used to determine growth rate of PAC, and whether it varied between depths (3 meters depth vs 9 meters depth)</p> <p>Growth Rate: Growth rate of PAC margin (micrometer/day) calculated using the number of days between when the tag was initially deployed to mark the margin of PAC to when the margin was re-measured again in January 2020.</p> <p dir=\"ltr\"><strong>Related datasets</strong> for Williams and Edmunds (2021) Coral Reefs manuscript:<br /> Figure 2a, <a href=\"https://www.bco-dmo.org/dataset/836071\">https://www.bco-dmo.org/dataset/836071</a><br /> Figure 3, <a href=\"https://www.bco-dmo.org/dataset/836164\">https://www.bco-dmo.org/dataset/836164</a><br /> Tables 1 and 2, <a href=\"https://www.bco-dmo.org/dataset/836304\">https://www.bco-dmo.org/dataset/836304</a></p> <div> </div>
<p><strong>重复编号（Replicate）</strong>：重复编号取值范围为1至80，为2019年8月至2020年1月间被标记的每一处太平洋柱珊瑚（PAC）生长边缘的唯一标识符，用于测定PAC的生长速率。</p> <p><strong>研究位点（Site）</strong>：位于美属维尔京群岛圣约翰岛拉穆尔湾（Lameshur Bay）的两处研究位点，在此处对PAC的生长边缘进行标记，以测定PAC的生长速率，并探究生长速率是否存在位点间差异，两个位点分别为卡布里特角（Cabritte Horn）与特基特礁（Tektite）。</p> <p><strong>水深（Depth）</strong>：标记位点处的水深，单位为米，取值为3米或9米，用于测定PAC的生长速率，并探究生长速率是否存在水深差异（3米水深组与9米水深组）。</p> <p><strong>生长速率（Growth Rate）</strong>：PAC生长边缘的生长速率，单位为微米/天（micrometer/day），计算依据为初始标记PAC生长边缘的日期，至2020年1月对该边缘再次测量的日期之间的天数。</p> <p dir="ltr"><strong>相关数据集</strong> 对应Williams与Edmunds（2021）发表于《Coral Reefs》的论文：<br /> 图2a：<a href="https://www.bco-dmo.org/dataset/836071">https://www.bco-dmo.org/dataset/836071</a><br /> 图3：<a href="https://www.bco-dmo.org/dataset/836164">https://www.bco-dmo.org/dataset/836164</a><br /> 表1与表2：<a href="https://www.bco-dmo.org/dataset/836304">https://www.bco-dmo.org/dataset/836304</a></p> <div> </div>
