Glacier Bay Murrelet Survey Raw Observations for 2016

Department of the Interior raw field observations from the 2016 Glacier Bay, Alaska murrelet survey. Data include murrelet bird group observations, their relation to line transects, covariates, tracklogs, and GPS points collected via a custom ArcGIS application. These data are stored in their original, unedited form as deliverable KM_C.

Use Cases

• Modeling murrelet population density based on line transect observations
• Analyzing seabird habitat use based on GPS point and tracklog data
• Studying the spatial distribution of Brachyramphus species based on group observation records
• Assessing survey methodology and data quality control processes for ecological monitoring

Strengths

• Data are stored in their original raw form, providing an unaltered record of field observations
• Includes multiple related data types: bird observations, covariates, tracklogs, and GPS points
• Collected via a standardized custom application for consistency

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
