Parent Layer: Density by species - April to July

Name: Common Tern - Density by species - April to July

Display Field: Group_Spec

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The atlas provides maps and datasets representing seabirds at-sea densities in eastern Canada. Data were collected using ships of opportunity surveys and therefore spatial and seasonal coverage varies considerably. Densities are computed using distance sampling to adjust for variation in detection rates among observers and survey conditions. Depending on conditions, seabirds can be difficult to identify at the species level.</SPAN></P><P><SPAN>The density maps present average seabird densities and their percent coefficient of variation per 100km hexagonal cells.</SPAN></P><P><SPAN>One map was created for each species by periods. Seabird densities were classified using a k-means scheme to ensure areas with the highest densities always clearly standup on each map. </SPAN></P></DIV></DIV></DIV>
