我们展示了对西南极洲一条主要冰川（松岛冰川）及其邻近海洋的亚年观测结果（2009 - 2014年）。几十年前，可能是由于海洋导致的冰川变薄加剧引发了持续的冰川消退和加速的冰流，这可能已经引发了海洋冰盖的不稳定。在2012年初到2013年末海洋热含量随后下降60%之后，冰流减缓，但是……
We present subannual observations (2009-2014) of a major West Antarctic glacier (Pine Island Glacier) and the neighboring ocean. Ongoing glacier retreat and accelerated ice flow were likely triggered a few decades ago by increased ocean-induced thinning, which may have initiated marine ice sheet instability. Following a subsequent 60% drop in ocean heat content from early 2012 to late 2013, ice flow slowed, but by
