Currently, sea turtle habitats are being altered by climate change and human activities, with habitat loss posing an urgent threat to Indian sea turtles. Thus, the objective of this study is to analyze the dynamic shoreline alterations and their impacts on Olive Ridley Sea Turtle (ORT) nesting sites in Gahirmatha Marine Wildlife Sanctuary from 1990 to 2022. Landsat satellite images served as input datasets to assess dynamic shoreline changes. This study assessed shoreline alterations and their rates across 929 transects divided into four zones using the Digital Shoreline Analysis System (DSAS) software. The results revealed a significant 14-km northward shift in the nesting site due to substantial coastal erosion, threatening the turtles' Arribada. This study underscores the need for conservation efforts to preserve nesting environments amidst changing coastal landscapes, offering novel insights into the interaction between coastal processes and marine turtle nesting behaviors.

动态海岸线变化及其对奥里萨邦加希尔玛塔海洋野生动物保护区橄榄蠵龟 (Lepidochelys olivacea) 筑巢地的影响（印度）

目前，气候变化和人类活动正在改变海龟的栖息地，栖息地的丧失对印度海龟构成了紧迫的威胁。因此，本研究的目的是分析 1990 年至 2022 年期间动态海岸线变化及其对加希尔玛塔海洋野生动物保护区橄榄蠵龟 (ORT) 筑巢地的影响。陆地卫星图像作为输入数据集来评估动态海岸线变化。本研究使用数字海岸线分析系统 (DSAS) 软件评估了分为四个区域的 929 个断面的海岸线变化及其速率。结果显示，由于严重的海岸侵蚀，筑巢地点明显向北移动了 14 公里，威胁到了海龟的阿里巴达。这项研究强调了在不断变化的沿海景观中保护筑巢环境的必要性，为沿海过程与海龟筑巢行为之间的相互作用提供了新的见解。
