  • A digital acoustic recording tag for measuring the response of wild marine mammals to sound 

    Johnson, Mark; Tyack, P L (2003-01) - Journal article
    Definitive studies on the response of marine mammals to anthropogenic sound are hampered by the short surface time and deep-diving lifestyle of many species. A novel archival tag, called the DTAG, has been developed to ...
  • Drag of suction cup tags on swimming animals : modeling and measurement 

    Shorter, K. Alex; Murray, Mark M.; Johnson, Mark; Moore, Michael; Howle, Laurens E. (2014-04) - Journal article
    Bio-logging tags are widely used to study the behavior and movements of marine mammals with the tacit assumption of little impact to the animal. However, tags on fast-swimming animals generate substantial hydrodynamic ...
  • Marine seismic surveys and ocean noise : time for coordinated and prudent planning 

    Nowacek, Douglas P.; Clark, Christopher W.; Mann, David; Miller, Patrick J. O.; Rosenbaum, Howard C.; Golden, Jay S.; Jasny, Michael; Kraska, James; Southall, Brandon L. (2015-09) - Journal item
    Marine seismic surveys use intense (eg >= 230 decibel [dB] root mean square [RMS]) sound impulses to explore the ocean bottom for hydrocarbon deposits, conduct geophysical research, and establish resource claims under the ...
  • Neutral buoyancy is optimal to minimize the cost of transport in horizontally swimming seals 

    Sato, Katsufumi; Aoki, Kagari; Watanabe, Yuuki Y.; Miller, Patrick J. O. (2013-07-16) - Journal article
    Flying and terrestrial animals should spend energy to move while supporting their weight against gravity. On the other hand, supported by buoyancy, aquatic animals can minimize the energy cost for supporting their body ...
