Space4SDG14: Life Below Water
Published by- Joy Agrawal on 23/07/2021
Preservation of life all around is quintessential, even a centipede is as important as a lion because all this maintains the ecological balance. Life below water also helps maintain that very balance and more importantly has social and economic benefits for the human civilisation. Life below water serves as food for major proportion of people it serves a source of sustenance for others. Most of our fresh water comes from the oceans and life below it helps ensure the quality of water through various methods. More importantly its a moral duty towards preservation of marine ecosystem because we have been sharing the Earth with them and we have been polluting oceans and hence for continuity of not only humans but also the marine ecosystem. Space technology can aid in a number of ways to contribute towards this goal.
How exactly does this work?
One major man made marine disaster that severely affects all life is oil spills. Oil spills have negative health effects on the marine life. Surface marine life faces obvious dangers due to toxic liquid. So how can such oil spills be detected?
Another major application of space tech is sea surface temperature, because this can be used to identify the weather patterns and more importantly the migration pattern of animals and develop models that will help decide the migration of aquatic life using surface temperature, regions found, tolerable temperature and oceanic currents.
Finally, plastics are the major pollutants affecting marine life. Ingestion of plastic can cause tremendous problems for the aquatic life. Suffocation due it is the major reason for the ill omen for the marine ecosystem. Majorly physical entanglement leads to a major problem. Imagine we have polluted the ocean so much that all needed to detect plastic from satellites is the colours of the ocean. Our litter is visible from space. Detection can aid in cleaning efforts which is crucial in this stage to preserve our marine ecosystem.
As discussed above, satellite imagery is key to helping keep the marine ecosystem free from the effects of industrialisation.
