And Brendan took some analyses across this coral -- you can see the marks -- and he's been able to show that these are actual annual bands, so even at 500 meters deep in the ocean, corals can record seasonal changes, which is pretty spectacular.
布兰登对这个珊瑚做了横切分析， 你们可以看到横向的标记， 他由此证明了这其实是珊瑚的年轮， 所以说即使在 海平面以下500米深处， 珊瑚可以记录季节的更替， 这其实是挺惊人的。
