Reduced female Steller sea lion reproductive rates and the Steller sea lion population.

High female mortality due to male aggression in Hawaiian monk seals led us to investigate the role of habitat use and social structure on sex ratios and aggression at Laysan Island, Hawaii.

In 1953, the Outer Continental Shelf Lands Act (OCSLA) (43 USC 1331-1356) charged the U.S. Secretary of the Interior with the responsibility for administering minerals exploration and development of the Outer Continental Shelf (OCS). The Act empowered the Secretary to formulate regulations so that its provisions might be met. The OCSLA Amendments of 1978 (43 USC 1802) established a policy for the management of oil and natural gas in the OCS and for protection of the marine and coastal environments. The amended OCSLA states that the Secretary of the Interior shall conduct studies in areas or regions of sales to ascertain the “environmental impacts on the marine and coastal environments of the outer Continental Shelf and the coastal areas which may be affected by oil and gas development” (43 USC 1346).

A study on the effects of ship disturbances on harbor seals in Alaska.

Beluga whale behavior before (2005–2006) and during (2008–2009) pile driving activity for the Port of Anchorage Marine Terminal Redevelopment Project.

Scientists analyzed beluga whale livers to look for temporal trends between PFC concentrations from two groups and to speculate on the different sources of PFCs. They examined geographical and gender differences, and possible bioaccumulation of PFCs.
