Scientists Track 1,000-Pound Great White Shark On The East Coast 
As many vacationers prepare to pack the beaches along the East Coast this summer, a 12-foot, 1,000-pound great white shark is being tracked as it roams along the shore. NBC's Emilie Ikeda reports for TODAY.

    It was the end of April, about 10:30 at night when off the Jersey shore the tracker pinged a 12-foot long 1000 pound great white shark was on the move, cruising up the east coast on the hunt for seals.

    But normally the massive creatures don't swim that far north until June. - Sometimes they take a shot⁽¹⁾ at it, because maybe once out of every 10 years, it's warm enough up there where they can move in, and eat seals starting a month early.

  • 3

    But when he hit the cold water the great white thought twice and turned back south again to North Carolina, his name is Ironbound⁽²⁾ after the island in Nova Scotia where the research group Osearch⁽³⁾ first tagged him.

  • 4

    He is a determined, you know, young mature male trying to make his way in the white shark world, and he has the attitude to do so.

  • 5

    Since late 2019 Ironbound has traveled 13,000 miles from Canada down to the Florida keys, where just like the snowbirds great whites like to warm up in the winter and while 12 feet may sound gargantuan they can get a lot bigger.

    Check out this one, Deep blue, caught on camera in Hawaii, forget for a moment the fearlessness of that diver and look at the size of the shark, 20 feet long, weighing two and a half tons.

  • 7

    The great white population has been rebounding for the last two decades, Cape Cod Massachusetts⁽⁴⁾ has become a hot spot, lots of seals lots of whites, the backdrop for that Hollywood classic.

    At least 47 people were attacked by sharks in the United States last year, including a California surfer and a 12-year-old girl swimming off the Maryland coast. - It felt like something ran into my legs and I ran out and I find blood everywhere.

  • 9

    In 2020, a great white killed a woman off the coast of Maine, but oceanographers stress that shark attacks are rare, and this predator is vital.

  • 10

    Well they manage the ocean system and if the ocean system's not working, we die, and these guys are the system managers, so if they thrive we thrive⁽⁵⁾.

  • 11

    Okay so where is Ironbound right now? you can actually follow his movements on Osearch's tracking system.

  • 12

    It shows that he is off the coast of north Carolina, but keep in mind great whites return to their same summer feeding spots every year.

  • 13

    So Ironbound will be passing through these waters again, sometime in the next few weeks making his way back to Nova Scotia guys.

  • 14

    That's terrifying, I love sharks but it's it's the case of mistaken identity that worries me. when I'm boogie boarding and the Jersey shore, I look like a delicious seal. - That's what like a chubby look not like an appetizer.

    那是4月底,大约晚上10点半左右,追踪器在泽西海岸外发现了一条12英尺(约3.65米)长、1000磅(约454kg)重的大白鲨,它正在移动,沿着东海岸巡航,猎寻海豹。

  • 2

    但通常这些大家伙不会往北游这么远,直到6月才会来。 - 有时它们会尝试一下,因为可能每10年才有一次,那里足够温暖,它们可以搬家到那里,提前一个月开始吃海豹。

  • 3

    但当它向北遇到冰冷的海水时,大白鲨考虑了两遍,再次向南返回北卡罗莱纳州,他的名字是“Ironbound”,来自加拿大新斯科舍省的一个岛,Osearch研究小组在那里首次标记了它。

  • 4

    它是一条有决心的鲨鱼,一条年轻的成年雄鲨试图在大白鲨的世界中闯出一片天地,它有这样的态度。

  • 5

    自2019年底以来,“Ironbound”已经从加拿大到达佛罗里达群岛旅行了13000英里(约20900公里),就像雪候鸟一样,大白鲨喜欢在冬天找温暖,虽然12英尺(约3.65米)听起来很庞大,但它们可以长得更大。

  • 6

    来看看这条名叫“深蓝”的鲨鱼,在夏威夷被水下相机拍到,暂时忘掉潜水员的无畏,看看这条鲨鱼的大小,20英尺(约6.1米)长,两吨半重。

  • 7

    在过去的20年里,大白鲨的数量一直在反弹,马萨诸塞州的科德角已经成为一个热点,有很多海豹很多大白鲨,也是那部好莱坞经典电影(1974《大白鲨》)的取景地。

  • 8

    去年,美国至少有47人遭到鲨鱼袭击,其中包括一名加州冲浪者和一名在马里兰州海岸游泳的12岁女孩。 - 感觉好像有什么东西扎进了我的腿,我逃回岸上,发现到处都是血。

  • 9

    2020年,一条大白鲨在缅因州海岸杀死了一名女性游客,但海洋学家强调,鲨鱼袭击事件很罕见,这种捕食者(对于海洋生态)至关重要。

  • 10

    它们管理着海洋系统,如果海洋生态系统不能正常工作,我们人类就会被袭,而这些大白鲨是海洋生态系统管理者,如果它们繁荣,我们就繁荣。

  • 11

    好吧,想知道大白鲨"Ironbound"现在在哪儿?你可以通过Osearch的追踪系统追踪它的行踪。

  • 12

    现在从Osearch的APP上看,系统显示这只"Ironbound"现在在北卡罗莱纳的海岸,但请记住,大白鲨每年都会回到它们相同的夏季觅食地点。

  • 13

    所以在接下来的几周内,它会再次穿过这片水域回到加拿大新斯科舍省。

  • 14

    太可怕了,我喜欢鲨鱼,但我担心它弄错了身份,当我在泽西海岸冲浪时,我怕被鲨鱼看成一只美味的海豹。 - 你是个胖乎乎的人类,不是它的开胃菜。
