Glacier Bay Murrelet Bird Survey Raw Observations for 2018

Raw field observations from the 2018 survey season in Glacier Bay, Alaska, collected by the Department of the Interior. Data include murrelet bird group observations, their relation to line transects, covariates, tracklogs, and GPS points. These data are stored in their original, unedited form after collection.

Use Cases

• Modeling murrelet habitat use based on GPS points and covariates mentioned in the description
• Analyzing bird observation density relative to line transects described in the survey
• Assessing survey effort and coverage using the tracklog data collected
• Conducting quality control comparisons with the separate corrected version (KM_D) referenced in the description

Strengths

• Data are stored in their original raw form and are never edited, preserving field integrity
• Includes multiple related data types: observations, covariates, tracklogs, and GPS points
• Survey is focused on a specific geographic area (Glacier Bay, Alaska) and year (2018)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
