2006
Pay-walled Journal Article

Animal Conservation

Croll, D. A., Clark, C. W., Calambokidis, J., Ellison, W. T. and Tershy, B .R.

The human contribution to ambient noise in the ocean has increased over the past 50 years, and is dominated by low-frequency (LF) sound (frequencies <1000 Hz)...

Free-swimming northern elephant seals have low field metabolic rates that are sensitive to an increased cost of transport

2014
Open Access Peer Reviewed Publication

The Journal of Experimental Biology

Maresh, J., Simmons, S., Crocker, D., McDonald, B. et al.

Widely ranging marine predators often adopt stereotyped, energysaving behaviours to minimize the energetic cost of transport while maximizing energy gain. Environmental and anthropogenic disturbances can disrupt...
