Integrated step selection analysis of turtle tracking data in the Florida Keys National Marine Sanctuary, 2008-2019

This dataset contains all input parameters required to perform integrated step selection analysis (iSSA) to quantify marine turtle habitat selection relative to marine protected areas throughout coastal Florida and the Gulf of Mexico. The iSSA is a flexible approach to compare the environmental attributes of observed steps (the linear segment connecting two consecutive observed positions of an animal) against a group of alternative steps taken from the same starting location. Information contained in the dataset includes original PIT (passively induced transponder, a unique identifier for each turtle), step ID, step length and log of the step length, turning angle and cosine of turning angle, start and end date time of each step, protected status of location of each step ID (unprotected, multi-use or no-take, water depth (in meters), and chlorophyll concentration (in mg/m3).

本数据集包含开展整合步选择分析（integrated step selection analysis, iSSA）所需的全部输入参数，用于量化佛罗里达沿海及墨西哥湾全域范围内海龟相对于海洋保护区的栖息地选择偏好。整合步选择分析是一种灵活的研究方法，可将观测步——即连接动物连续两个观测位置的线性段——的环境属性与同一起始位置生成的一组备选步进行对比。本数据集涵盖的信息包括：每只海龟唯一标识符的被动集成应答器（passively induced transponder, PIT）编号、步编号、步长及步长对数、转向角及转向角余弦值、每个步的起止日期时间、各步对应位置的保护状态（分为未保护、多用途或禁捕）、水深（单位：米）以及叶绿素浓度（单位：mg/m³）。
