First autonomous recording of in situ dissolved oxygen from free-ranging fish

摘要: Biologging technology has enhanced our understanding of the ecology marine animals and been central to identifying how oceanographic conditions drive patterns in their distribution behavior. Among these environmental influences, there is increasing recognition impact dissolved oxygen on animals. Understanding vertical horizontal movements would be advanced by contemporaneous situ measurements from animal-borne sensors instead relying data that may not have appropriate spatial or temporal resolution. Here, we demonstrate capabilities pop-up satellite archival tags (DO-PATs) presenting results calibration experiments trial deployments two prototype bluntnose sixgill sharks (Hexanchus griseus). The DO-PATs provided fast, accurate, stable trials demonstrated high correlation with profiles obtained via traditional ship-borne instruments. Deployments recorded saturations as low 9.4 % effectively captured oceanography region when compared World Ocean Atlas 2013 values. This first study use an device autonomously measure record saturation non-air-breathing maintained consistency over time yielded equivalent industry standards for sampling. Acquiring alongside temperature depth will greatly improve ability investigate make informed predictions impacts global climate change. information returned relevant only but also become a useful new tool investigating physical structure oceans.
