Glacier Bay Murrelet Survey Raw Observations for 2011

2011 raw field observations of murrelet bird groups collected during surveys in Glacier Bay, Alaska. The data, produced by the Department of the Interior, includes observations relative to line transects, covariates, tracklogs, and GPS points. Data are stored in their original, unedited form as recorded via a custom ArcGIS application on laptops and iPads.

Use Cases

• Modeling murrelet habitat use based on GPS point and transect relation data
• Analyzing survey effort and coverage based on recorded tracklogs
• Studying bird group distribution patterns from the raw observation records
• Assessing data collection protocols by comparing raw and corrected data versions

Strengths

• Data are stored in their original, unedited raw form after field collection.
• Observations include multiple data types: bird groups, transect relations, covariates, tracklogs, and GPS points.
• Collected using a standardized method via a custom ArcGIS application.

Limitations

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