Climate and contamination of the western arctic: monitoring change with the Black Guillemot, an apex marine predator

Updated 2001-06-29

Examine temporal and spatial variation in trace metal concentrations in the western Arctic through the analysis of Black Guillemot feathers. Temporal trends being examined using study skins collected as early as 1897. Spatial variation examined in conjunction with carbon isotope signatures in feathers and by sampling both winter and summer plumages. Regional climate change monitored through examination of annual variation in breeding chronology and success in relation to snow and ice melt.

This is not a National Implementation Plan (NIP) project

Methods & Procedures

Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.

Feathers are being obtained from historical museum specimens and from living birds in the field. Analysis of methyl mercury, cadmium and lead being done by Frontier Geosciences in Seattle, Washington.
