Santa Catalina Island Seastar Monitoring Data from 1984 to 2007

Data were collected annually in spring from 1984 to 2007 at WMSC seawater intake pipes and Bird Rock along fixed band transects (3m by 60m) at 3 depths (5m, 10m, 15m). Seastars Pisaster giganteus and Patiria miniata were counted and measured in each transect. The purpose of the data is to evaluate long-term abundance trends, particularly with relation to seastar wasting disease outbreaks.

本数据集于1984年至2007年每年春季采集完成，采样点位设置于WMSC海水取水管及鸟岩（Bird Rock）区域。采样采用固定带状样带（fixed band transects）设计，样带规格为3米×60米，分别在5米、10米、15米三个水深处布设。研究人员在每条样带内对巨海盘车（Pisaster giganteus）与迷你海燕（Patiria miniata）两种海星进行计数及形态测量。本数据集的核心研究目标为评估海星种群丰度的长期变化趋势，尤其聚焦于与海星消瘦病（seastar wasting disease）暴发相关的种群动态变化。
