Summary sponge abundance by species and site on the coral reefs of St. John USVI from photoquadrats taken between 1992 and 2017

<p>Abundance of sponges (on both density scale – number per quadrat – and volume scale – estimated volume per quadrat) for three sites over time on the shallow coral reefs of St. John from 1992-2017. Data support Figure S2 in the paper published in&nbsp;Marine Biology (Edumunds et al., 2020).&nbsp;</p> <p>Other datasets from Edmunds et al. (2020) are listed on the page https://www.bco-dmo.org/related-resource/819411.</p>本数据集收录了1992年至2017年间圣约翰岛浅海珊瑚礁上三个采样点的海绵丰度数据，涵盖两种度量尺度：密度尺度（每样方（quadrat）个体数）与体积尺度（每样方估算体积）。本数据支撑发表于《海洋生物学（Marine Biology）》（Edumunds等人，2020）的论文中的补充图S2。 Edmunds等人（2020）的其他相关数据集可在以下页面查阅：https://www.bco-dmo.org/related-resource/819411。
