SAS code for extracting dive profile information from archival geolocator tags

Attributes of dives (i.e., proportion of time underwater, depth of dive, ascent and descent rates, duration of dive, time within 2 m of maximum depth, post dive surface interval) are extracted from pressure data, where depth (m) = pressure (dbars) * 1.019716 using the SAS software code provided. Dives were considered to be submergence below the water surface, which are define as recorded depth of >0.8 m (typical body length of adult common loons in this study). Because pressure data were collected at 20-sec intervals, we interpolated the times of both dive initiation and surfacing. Average ascent and descent rates were estimated individually for each loon and used to interpolate these times, where rates were based...

Distribution and foraging patterns of common loons on Lake Michigan with implications for exposure to type E avian botulism: Data

Common loons (Gavia immer) staging on the Great Lakes during fall migration are at risk to episodic outbreaks of type E botulism. Information on distribution, foraging patterns, and exposure routes of loons are needed for understanding the physical and ecological factors that contribute to avian botulism outbreaks. Aerial surveys were conducted to document the spatiotemporal distribution of common loons on Lake Michigan during falls 2011–2013. In addition, satellite telemetry and archival geolocator tags were used to determine the distribution and foraging patterns of individual common loons while using Lake Michigan during fall migration. Common loon distribution observed during aerial surveys and movements of...
