With reference to the arctic ice, consider the following statements:1....
According to a study published in the ‘Science’, the journal of the American Association for the Advancement of Science there is a changing chemistry of the western region of the Arctic Ocean after discovering acidity levels increasing three to four times faster than ocean waters elsewhere.
  • The team of researchers identified a strong correlation between the accelerated rate of melting ice and the rate of ocean acidification.
  • Scientists have predicted that by 2050, Arctic sea ice in this region will no longer survive the increasingly warm summers. 
  • As a result, the ocean’s chemistry will grow more acidic, creating life-threatening problems for the diverse population of sea creatures, plants and other living things that depend on a healthy ocean. Crabs, for example, live in a crusty shell built from the calcium carbonate prevalent in ocean water. 
  • Seawater is normally alkaline, with a pH value of around 8.1.
  • The researchers point to sea-ice melt as the key mechanism to explain this rapid pH decrease, because it changes surface water in three primary ways.
    • First, the water under the sea ice, which had a deficit of carbon dioxide, now is exposed to the atmospheric carbon dioxide and can take it up freely.
    • The seawater mixed with meltwater is light and can’t mix easily into deeper waters, which means the carbon dioxide is concentrated at the surface.
    • The meltwater dilutes the carbonate ion concentration in the seawater, weakening its ability to neutralise the carbon dioxide into bicarbonate and rapidly decreasing ocean pH.
Hence both statements are correct.
