NotesThis thesis examines marine mammals found dead on the Oregon Coast from 2006-2014: where they were found, when they were found, and how they died. The author correlates animal deaths with climate conditions and human activities. Human beings were shown to cause far more deaths than disease or other causes. “Spatial analysis shows that stranding hot spots occur near major coastal estuaries: the mouth of the Columbia River, Siletz Bay, Yaquina Bay, and Coos Bay (p.60).”
