Loss of Ice in Antarctica Leads to a Change in Ocean Ecology

The recent developments across the globe have led to various changes in the global climate. Besides the climatic changes, the submarine world has faced one of the grave consequences. In the last two decades the region around the Antarctica peninsula has seen the emergence of glass sponges also known as Hexactinellida. This formation has been due to tempestuous break-up of the Larsen Ice Shelf.

It was in the year 1995 when this floating glacier got collapsed in the Antarctic region. This did not result in changes in the temperature beneath the ocean but has restricted the reach of light deep inside the ocean. Over the centuries, the ocean has been maintaining a steady water flow and a temperature of about -2°C. However, the difference has been that the ocean is now exposed to sunlight for over 6 months in a year which once used to be covered by ice. As per the reports by the German researches, a filter feeding animal which grew in small numbers in the ocean is now seen in vast numbers and is believed to have grown rapidly in the region.

Latest developments and observations indicate that the glass sponges might undergo a boom and bring a change in the normal cycles. This would lead to colonisation of newer habitats that too at a very fast speed.
