Glacier Bay Murrelet Survey Raw Observations for 2017

Raw field observations of murrelet bird groups collected during 2017 surveys in Glacier Bay, Alaska. Data were recorded directly into an ArcGIS geodatabase via a custom application on laptops and iPads, capturing observations, transect relations, covariates, tracklogs, and GPS points. The dataset is maintained by the Department of the Interior and is stored in its original, unedited form.

Use Cases

• Modeling murrelet habitat use based on GPS points and covariates collected during transects.
• Analyzing bird group distribution patterns in relation to line transects.
• Assessing survey effort and coverage using recorded tracklogs.
• Conducting quality control comparisons against the separate corrected version (KM_D).

Strengths

• Data are stored in their original raw form, providing an unaltered record of field observations.
• Collection method used a custom application for direct entry into an ArcGIS geodatabase, which likely reduces transcription errors.
• Dataset includes multiple related data types: observations, covariates, tracklogs, and GPS points.

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.
