The value of remote sensing techniques in supporting effective extrapolation across multiple marine spatial scales [PDF]

open access: yes, 2017
The reporting of ecological phenomena and environmental status routinely required point observations, collected with traditional sampling approaches to be extrapolated to larger reporting scales.

How man-made interference might cause gas bubble emboli in deep diving whales

open access: yesFrontiers in Physiology, 2014
Recent cetacean mass strandings in close temporal and spatial association with sonar activity has raised the concern that anthropogenic sound may harm breath-hold diving marine mammals.

Novel Bio-Logging Tool for Studying Fine-Scale Behaviors of Marine Turtles in Response to Sound

open access: yes, 2017
Increases in the spatial scale and intensity of activities that produce marine anthropogenic sound highlight the importance of understanding the impacts and effects of sound on threatened species such as marine turtles.

Decompression versus decomposition: distribution, quantity and gas composition of bubbles in stranded marine mammals

open access: yesFrontiers in Physiology, 2012
"Gas Bubble Disease" or Decompression-like Sickness" was described in stranded beaked whales linked to military sonar. Findings of gas bubble presence or associated lesions in marine mammals have been reported more and more often during ...

Male sperm whale acoustic behavior observed from multipaths at a single hydrophone [PDF]

open access: yes, 2005
Sperm whales generate transient sounds (clicks) when foraging. These clicks have been described as echolocation sounds, a result of having measured the source level and the directionality of these signals and having extrapolated results from biosonar ...

Facilitating macrosystem biology with organismal‐scale airborne remote sensing: Challenges and opportunities

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Emergent ecosystem properties, such as population and trait distributions, biodiversity and energy and water fluxes, occur because of the dynamic interactions of individuals in their environment.

Declining abundance of beaked whales (family Ziphiidae) in the California Current large marine ecosystem.

open access: yesPLoS ONE, 2013
Beaked whales are among the most diverse yet least understood groups of marine mammals. A diverse set of mostly anthropogenic threats necessitates improvement in our ability to assess population status for this cryptic group.
