The process slightly, but measurably, lubricates and accelerates the grinding passage of ice towards the sea.

虽然效果并不显著，但此过程实实在在地加速了冰川融化流向大海。
参考
整个过程对冰划入海洋起着润滑和加速的作用，虽然过程缓慢，但作用明显。
问题

  • 漏译lubricate
  • lubricate/accelerate 对…起着润滑的加速的作用
  • slightly/measurably 判断表态放后

Most important,many glaciologists say, is the break-up of huge semi-submerged clots of ice where some large Greenland glaciers, particularly along the west coast, squeeze through fiords as they meet the warming ocean. As these passages have cleared, this has sharply accelerated the flow of many of these creeping, corrugated and frozen rivers.

格林兰岛（特别是沿西海岸）的大型冰川一遇到暖洋就挤压变形，附近半显露的巨型冰川块也随之断裂，冰川学家表示这种情况才是最值得关注的。虽然碎冰清理干净了，原本冻住的几条河却因此流速大幅变快。

在格陵兰岛的一些大型冰川特别是西海岸的冰川在进入逐渐变暖的海洋时勉强穿过峡湾，这时一些大型的半浸没水中的巨大冰体会断裂开来，许多冰川学家认为这是最重要的一环。当冰川通过峡湾后，这些缓慢流动、泛着波纹的融冰河流动速度将大大加快。

  • 漏译：squeeze through fiords (manage to get into or through (a restricted space)/currugated (formed into folds or furrows : having a ridged or furrowed surface)
  • fiord: a long narrow strip of sea between high cliffs, especially in Norway （尤指挪威两岸峭壁间的）峡湾
  • clots of ice 冰体
  • frozen rivers 融冰河
