From the killer shark of "Jaws" to the tornado-tossed predators of the "Sharknado" movies, films long have portrayed sharks as objects of summer fear. But when a shark cuts through the waters off the U.S. East Coast, it now may be doing more than hunting. It may also be gathering data that helps scientists understand the potential intensity of a hurricane before it makes landfall.
University of Delaware researchers are testing whether sharks can serve as mobile near-real-time ocean-data observers, carrying sensors that measure ocean conditions to inform oceanographic, atmospheric and climate models.
从《大白鲨》里的杀人鲨到《鲨卷风》电影中被龙卷风卷起的掠食者，电影长期以来都把鲨鱼描绘成夏日的恐惧之源。但当一条鲨鱼划过美国东海岸附近的水域时，它现在所做的可能不仅仅是捕猎，还可能在收集数据，帮助科学家在飓风登陆前了解其潜在强度。
特拉华大学的研究人员正在测试鲨鱼能否充当移动的近乎实时的海洋数据观测者——它们携带传感器测量海洋状况，为海洋学、大气和气候模型提供数据。
