Polycyclic aromatic hydrocarbons (PAHs) are complex mixtures that form when organic matter is burned. Humans are primarily exposed to PAHs via air pollution from incomplete combustion of fossil fuels and biomass, such a motor vehicle exhaust, cigarette smoke, wood smoke, or industrial emissions; or via ingestion of PAHs bound to...

In 2014, Oregon State University (OSU) initiated a multi-year project to study humpback whale (Megaptera novaeangliae) migrations in the North Pacific Ocean using satellite tracking technology in combination with genetic and photo-identification (photo-ID) analyses. The study is highly relevant to management, given the need for new information arising from the...
During their migrations, marine predators experience varying levels of protection and face many threats as they travel through multiple countries' jurisdictions and across ocean basins. Some populations are declining rapidly. Contributing to such declines is a failure of some international agreements to ensure effective cooperation by the stakeholders responsible for...
Stressors associated with human activities interact in complex ways to affect marine ecosystems,
yet we lack spatially explicit assessments of cumulative impacts on ecologically and
economically key components such as marine predators. Here we develop a metric of
cumulative utilization and impact (CUI) on marine predators by combining electronic tracking...

The last deglaciation of the Scandinavian Ice Sheet (SIS) from ∼21,000 to 13,000 yr ago is well-constrained by several hundred ¹⁰Be and ¹⁴C ages. The subsequent retreat history, however, is established primarily from minimum-limiting ¹⁴C ages and incomplete Baltic-Sea varve records, leaving a substantial fraction of final SIS retreat history...
