Hi MARMAM community, My colleagues and I are pleased to announce the publication of a literature review focusing on the known impacts of unmanned aerial systems on marine mammals. This review is one of a special series of invited papers on the use of unmanned vehicle systems in wildlife studies. Assessment of known impacts of unmanned aerial systems (UAS) on marine mammals: data gaps and recommendations for researchers in the United StatesCourtney E. Smith, Seth T. Sykora-Bodie, Brian Bloodworth, Shalynn M. Pack, Trevor R. Spradlin, Nicole R. LeBoeuf. Journal of Unmanned Vehicle Systems, Published on the web 22 January 2016, 10.1139/juvs-2015-001. Abstract: The development of advanced technologies to enhance conservation science often outpaces the abilities of wildlife managers to assess and ensure such new tools are safely used in proximity to wild animals. Recently, unmanned aerial systems (UAS) have become more accessible to civilian operators and are quickly being integrated into existing research paradigms to replace manned aircraft. Several federal statutes require scientists to obtain research permits to closely approach protected species of wildlife, such as marine mammals, but the lack of available information on the effects of UAS operations on these species has made it difficult to evaluate and mitigate potential impacts. Here, we present a synthesis of the current state of scientific understanding of the impacts of UAS usage near marine mammals. We also identify key data gaps that are currently limiting the ability of marine resource managers to develop appropriate guidelines, policies, or regulations for safe and responsible operation of UAS near marine mammals. We recommend researchers prioritize collecting, analyzing, and disseminating data on marine mammal responses to UAS when using the devices to better inform the scientific community, regulators, and hobbyists about potential effects and assist with the development of appropriate mitigation measures.
