Animal-borne tags are effective instruments for collecting ocean data and can be used to fill spatial gaps in the observing network. We deployed the first conductivity, temperature, and depth (CTD) satellite tags on the dorsal fin of salmon sharks (Lamna ditropis) to demonstrate the potential of sharks to monitor essential ocean variables and oceanographic features in the Gulf of Alaska. Over 1360 km and 36 days in the summer of 2015, the salmon shark collected 56 geolocated, temperature-salinity profiles. The shark swam through a plume of anomalously salty water that originated from the "Blob" and encountered several mesoscale eddies, whose subsurface properties were altered by the marine heatwave. We demonstrate that salmon sharks have the potential to serve as submesoscale-resolving oceanographic platforms and substantially increase the spatial coverage of observations in the Gulf of Alaska.
动物背负的标签是收集海洋数据的有效工具，可用于填补观测网络中的空间空白。我们在鲑鱼鲨（Lamna ditropis）的背鳍上部署了第一批电导率、温度和深度（CTD）卫星标签，以展示鲨鱼监测阿拉斯加湾基本海洋变量和海洋特征的潜力。在 2015 年夏天的 36 天里，鲑鱼鲨游过了 1360 多公里，采集了 56 个地理位置、温度-盐度剖面。鲨鱼游过了一股起源于“Blob”的异常咸水羽流，并遇到了几个中尺度涡流，海洋热浪改变了它们的次表层特性。我们证明了鲑鱼鲨有潜力成为亚中尺度海洋学平台，并大大增加了阿拉斯加湾的观测空间覆盖范围。
