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

Sponge abundances on the shallow coral reefs of St. John from 1992-2017. Data were extracted from legacy photoquadrats that are part of an ongoing time series, and sponge abundances were expressed as number per quadrat (“Abundance”). Data are presented by taxon, and support Table 1, Figure 4, 5 and S1 in the paper published in Marine Biology (Edumunds et al., 2020). Other datasets from Edmunds et al. (2020) are listed on the page https://www.bco-dmo.org/related-resource/819411.1992年至2017年圣约翰浅海珊瑚礁的海绵丰度数据。数据提取自隶属于某一正在进行的时间序列监测项目的遗留摄影样方（photoquadrats），海绵丰度以每样方的个体数为计量单位，指标记为‘丰度（Abundance）’。数据按分类群（taxon）进行整理呈现，支撑了发表于《海洋生物学（Marine Biology）》的Edmunds等人（2020）论文中的表1、图4、图5及补充材料图S1。 Edmunds等人（2020）的其他数据集可在以下页面查阅：https://www.bco-dmo.org/related-resource/819411
