弹出式卫星档案标签植入68大西洋蓝鳍金枪鱼（Thunnus thynnus Linnaeus），从91至295公斤的大小，在南部的海湾缅因州（n=67）和外海的北卡罗来纳州（n=1）之间的2002年7月和2003年1月。在缅因州湾被标记的个体在晚秋离开该地区，在弗吉尼亚州和北卡罗来纳州海岸外的北方陆架沃茨或西北大西洋的近海沃茨越冬。在春天，这些鱼要么向北移动到缅因州海湾，要么离岸。没有一条鱼越过西经45°管理线（分隔东西管理单位），也没有一条鱼游向墨西哥湾或佛罗里达海峡（已知的西大西洋产卵场）。记录的最大深度为672米，鱼经历的温度范围为3.4至28.7°C。游泳深度与地点、季节、大小类、一天中的时间和月相显著相关。也有证据表明，与海洋学特征有关的垂直行为和深度分布的变化是同步的。
Pop-up satellite archival tags were implanted into 68 Atlantic bluefin tuna (Thunnus thynnus Linnaeus), ranging in size from 91 to 295 kg, in the southern Gulf of Maine (n=67) and off the coast of North Carolina (n=1) between July 2002 and January 2003. Individuals tagged in the Gulf of Maine left that area in late fall and overwintered in northern shelf waters, off the coasts of Virginia and North Carolina, or in offshore waters of the northwestern Atlantic Ocean. In spring, the fish moved either northwards towards the Gulf of Maine or offshore. None of the fish crossed the 45°W management line (separating eastern and western management units) and none traveled towards the Gulf of Mexico or the Straits of Florida (known western Atlantic spawning grounds). The greatest depth recorded was 672 m and the fish experienced temperatures ranging from 3.4 to 28.7°C. Swimming depth was significantly correlated with location, season, size class, time of day, and moon phase. There was also evidence of synchronous vertical behavior and changes in depth distribution in relation to oceanographic features.
