Even in today’s world the ocean is largely unexplored, we are learning new…

The top layer is called the sunlight, or euphotic, zone which is the top of the ocean, what we see without having any special submarine gear, to about 200 meters. In many situations, sunlight does not go beyond this level. Below that is the twilight, or dystophic, zone, which travels from…

Calving is also a result of the “formation of large crevasses” which occur as a result of the warming ocean thinning the ice shelves (Scripps Institution of Oceanography, 2016). While they play an important role in calving, melt ponds have also been linked to the ‘disintegration’ mode of ice shelf breakups, with studies observing that ice shelves with melt ponds…
