Glacier Bay Alaska Murrelet Survey Raw Observations for 2015

Raw, unedited field observations of murrelet bird groups collected during 2015 surveys in Glacier Bay, Alaska. Data were recorded directly into a geodatabase via a custom application on laptops and iPads, capturing observations, transect relations, covariates, tracklogs, and GPS points. The Department of the Interior maintains this original data version, which precedes a separate quality-controlled deliverable.

Use Cases

• Modeling murrelet distribution based on GPS points and tracklogs mentioned in the description
• Analyzing bird group behavior in relation to line transects described in the data collection
• Assessing environmental covariates recorded during the field survey
• Validating automated data collection methods for ecological fieldwork

Strengths

• Data are stored in their original raw form and are never edited, preserving field accuracy
