Sea otter foraging data, visual observations from Prince of Wales, Alaska

Sea otter diets were assessed during summertime 2018 (May-August) visual observations from land. Data were collected on western Prince of Wales Island Alaska, at various sites where sea otter densities are high. These data were collected as a part of an NSF-funded project: Apex Predators, Ecosystems, and Community Sustainability (APECS, http://apecs-ak.org/). Other datasets to support this work are also archived with KNB.

2018年夏季（5月至8月），本研究通过陆地目视观测对海獭食性进行了评估。数据采集于美国阿拉斯加州威尔士王子岛西部海獭密度较高的多个观测点位。这些数据隶属于美国国家科学基金会（National Science Foundation, NSF）资助的研究项目——顶级捕食者、生态系统与群落可持续性（Apex Predators, Ecosystems, and Community Sustainability，APECS，http://apecs-ak.org/）。本研究配套的其他数据集亦存档于KNB。
