Photoquadrant of Benthic monitoring in Comau Fjord@en

In the year 2023, a comprehensive measurement campaign was conducted across various seasons at multiple sites, including Lilihuapi, Caleta Soledad, XhuinayN, Muelle, and Punta Huinay, with the aim of evaluating the abundance and diversity of sessile and mobile benthic macrofauna species. The results of this study are presented in this report. Building upon the methodology refined by Villalobos et al. (2021), this research was carried out by the scientific diving team at the Huinay Scientific Station. The methodology primarily relies on the use of photo-quadrants for underwater image capture, facilitating precise species identification and estimation of relative abundance. Monitoring was conducted across different seasons to capture potential seasonal variations in the composition and abundance of benthic species, providing a comprehensive and detailed view of ecosystem dynamics.

2023年，研究团队于Lilihuapi、Caleta Soledad、XhuinayN、Muelle及Punta Huinay等多个站点的不同季节开展综合性测量工作，旨在评估固着型与移动型底栖大型动物物种的丰度与多样性。本报告呈现了该研究的全部结果。本研究依托Villalobos等人（2021）优化完善的研究方法，由惠奈科学站（Huinay Scientific Station）的科学潜水团队实施。研究方法核心为采用照片样方（photo-quadrants）进行水下图像采集，以实现精准的物种识别与相对丰度估算。本次监测覆盖多季节，以捕捉底栖物种种群组成与丰度的潜在季节变化，从而全面细致地展现该区域的生态系统动态。
