Yakuta South Alaska Coastal Wildlife Surveys 2004-2005

This data set contains coastal survey data for summer and winter for the
Yakutat, southern Alaska, region. It covers basic transects for marine
wildlife, e.g. waterbirds, seabirds and sea mammals, along the coast. Data were
collected with unlimited width surveys (index of relative abundance) from a
jetboat (1.5m eye height) on both sides of the boat, throughout the years
2004-2005. In addition, encountered Marbled and Kittlitz's Murrelets were
surveyed from one side of the boat with DISTANCE Sampling protocol to obtain
compatability, e.g. densities corrected for detectability. This data set
contributes to a coastal inventory of coastal wildlife of the U.S. Forest
Service Yakutat region, and can be used to assess murrelet abundances in the
Northern Pacific waters.

本数据集涵盖阿拉斯加南部亚库塔特（Yakutat）地区夏冬两季的海岸调查数据。其包含沿海区域海洋野生动物（如水鸟、海鸟及海洋哺乳类）的基础样带调查内容。调查于2004至2005年间开展，采用无宽度限制的相对丰度指数调查法，以眼高1.5米的喷射快艇为作业平台，在船身两侧同步采集数据。此外，针对偶遇的斑海雀（Marbled Murrelet）与基特利茨小海雀（Kittlitz's Murrelet），本数据集采用距离取样（DISTANCE Sampling）规范，仅在船的一侧开展专项调查，以获取具有可比性的种群密度数据——即经可检测性校正后的种群密度。本数据集可为美国林务局（U.S. Forest Service）亚库塔特地区的海岸野生动物普查提供数据支撑，同时可用于评估北太平洋水域内小海雀的种群丰度。
