A number of reasons stand out:
# It is far from civilization, with its ozone-as-smog, # It has an annual "feature", an ozone "hole" that is larger and "deeper" than its northern counterpart, # It is now manned year-round, # It belongs to no nation, so there are no "diplomatic" issues involved in multi-national studies, and # It is largely based on a continent, with real land underneath.
There is more ozone depletion in the Antarctic region compared to other regions due to the presence of polar stratospheric clouds, which facilitate the chemical reactions that lead to ozone depletion. Additionally, the extreme cold temperatures in the Antarctic region create conditions that amplify the effects of ozone-depleting substances, such as chlorofluorocarbons (CFCs). The Antarctic ozone hole is also influenced by the polar vortex, which isolates the area and prevents ozone-rich air from entering the region.
As chlorine concentration rises, the concentration of ozone in the atmosphere decreases. This is because chlorine reacts with ozone, breaking it down into oxygen molecules, thereby depleting the ozone layer.
Ozone is more concentrated between 20-30 kilometers above earth's surface. Its concentration is 2-6 parts per million.
The ozone hole refers to a region in the Earth's stratosphere where the concentration of ozone is significantly depleted. This thinning of the ozone layer allows more ultraviolet (UV) radiation from the sun to reach the Earth's surface, which can be harmful to human health, ecosystems, and the environment.
This is a thinning (by about 2/3, of the ozone over the Antarctic during the spring time, towards the end of the long winter night in the south pole. There is no actual hole in the layer. This has occurred for centuries, in fact the thinnest we know the layer has ever been is in 1858, before man started using cfc's. A similar thinning occurs, to a much smaller extent in the Arctic during the end of it's winter night also. The thinning is much smaller in the Arctic and NASA even reffers to this thin area as the "Dimple" due to the small size.

Yes, it appears that it does. The Antarctic ozone hole has recently (2009) been near record size, and despite tiny increases in global temperatures, more area is covered with ice in/around the Antarctic.

The Antarctic is more stable and easier to access, but has the disadvantage of a large atmospheric ozone hole.

The largest ozone hole is above the Antarctic. It is almost as large as continental United States. Antarctic winters are very, very cold. When ice freezes in the air, the crystals are formed. This helps chlorine attack ozone molecules. Then, in the spring, the sun's ultra-violet rays break up the CFCs (ChloroFluoroCarbons) and making even more chlorine. Thus, the ozone is completely gone. But, the ozone levels are known to increase in the summertime.
The holes in the ozone layer are areas of depleted ozone concentration in Earth's stratosphere. These holes are primarily caused by human-made chemicals such as chlorofluorocarbons (CFCs) and halons, which release chlorine and bromine atoms that destroy ozone molecules. Ozone layer depletion can lead to increased exposure to harmful UV radiation from the sun, with potential impacts on human health and the environment.
I don't know what the 'roaring 40's' are but ozone reflects the light and heat of the sun so a lack of ozone over the antarctic means more heat get through which means the antarctic warms up and because ice reflects sunlight too and the increased heat in the antarctic means this ice melts, global temperatures increase by a lot.
diffuse towards area with more water . diffusion happens where it is from higher concentration to lower concentration . so more water of course higher concentration , less water of course lower concentration . this is what i think . but don guarantee correct answer .
