Answer:
The primary aim of ice patrol flights is to monitor icebergs near important shipping lanes to ensure maritime safety. Ice on the ocean already displaces water, so its melting does not significantly raise sea levels, whereas melting glaciers on land do contribute to sea level rise. Scientific studies, like tracking ice in the Antarctic, deepen our understanding of climate change.
Step-by-step explanation:
The primary objective of ice patrol flights is to observe ice floating in the vicinity of major shipping routes and maritime operations, most notably near the North Atlantic where dangers from icebergs are prevalent. These patrols play a critical role in ensuring maritime safety by tracking the movement and potential hazards posed by icebergs to sea vessels. When considering the impact of ice melting on sea levels, it's important to note that ice floating on the ocean, such as icebergs, is already displacing water, so its melting does not have a significant impact on sea level. However, when glaciers on land, which are not displacing water, melt and contribute to the ocean, it results in an increase in sea level.
Relating to polar research missions, spacecraft like the Phoenix, which landed near the north polar cap of Mars, have made valuable contributions in understanding the characteristics of polar regions in other planets. The discovery of frozen water or ice beneath the surface on Mars suggests parallels between Earth's polar regions and those of other planetary bodies.
Scientific cruises, such as the one carried out by South African scientists who placed trackers on ice in the Marginal Ice Zone of Antarctica, further our knowledge of ice dynamics and contribute to the global understanding of climate change and its effects on Earth's polar environments.
