Antarctic Ice Collision
-
Large ice shelves such as the Ross Ice Shelf on the western Antarctica coastline undergo periodic episodes of large-scale iceberg calving. In 2000, several large pieces of the shelf broke off and wandered around in the Ross Sea, breaking into several smaller bergs over the next few years. Among the survivors of the initial calving event is piece C-16. In late March 2006, C-16 worked its way northward along the coastline and plowed into the tip of the Drygalski Ice Tongue. The collision knocked loose a chunk from the tip of the ice tongue.
These images show iceberg C-16 and the Drygalski Ice Tongue before and after the collision. On March 26, the table-like C-16 was poised at the southern edge of the ice tongue, but buffered from direct contact by a small wedge of sea ice. According to scientists at the Space Science and Engineering Center at University of Wisconsin, Madison, who monitor the activity, C-16 had to overcome strong winds, known as katabatic winds, that blow down the topographic incline from the top of David Glacier (the source of the ice tongue) toward the sea. The katabatic winds would have been driving the berg toward the east, but not strongly enough to completely clear the ice tongue. The image from March 31 shows that C-16 had clipped the tip of the ice tongue, breaking off a piece. By April 3, both pieces of ice had swung around to the other side of the ice tongue.
Scientists monitor ice conditions such as calving and sea ice formation in the Ross Sea for both scientific and practical reasons. Ice processes in polar regions are important indicators of climate change, and the movements of sea ice and icebergs affect shipping lanes to the research bases in AnarticaÂ’s McMurdo Sound. Satellite observations are critical for this monitoring task because of the remoteness and extreme harshness of the climate.

What is the implications? Sea level rises?
-
The same as one would expect, rising sea levels, probably a few species might just go extinct or endangered. Other countries might not be affected now, but sooner or later it will be. More species might be on the verge of extinction if those at the start of the food chain are affected.Originally posted by ~Science~:What is the implications? Sea level rises? -
Temperature likely to change colder for some places, sea level is going to rise, some island country slightly above sea level may be affected.
Cold places will need more fuel for heating and the more we do it, the faster and more ice will melt... Go for Green is the only way out.. -
Do you think this may cause another wave of Tsunami?Originally posted by ndmmxiaomayi:The same as one would expect, rising sea levels, probably a few species might just go extinct or endangered.

Unlikely. Tsunami was caused by movement of the platform. This only increase water level and lower down temperature (freezing type). My view.Originally posted by ~Science~:Do you think this may cause another wave of Tsunami?

There are underwater waves which are strong enough to cause tsunami, but it's unlikely that it will cause another wave of tsunami, unless a huge block just fall off right into the ocean. Even then, water can handle impact much more than hard ground, so a tsunami is unlikely.Originally posted by ~Science~:Do you think this may cause another wave of Tsunami? -
On the other hand, other countries get warmer. More water evaporating off, and we are going to get more deserts. More droughts to expect. Countries like Holland might just sink off Earth's surface.Originally posted by king108: Temperature likely to change colder for some places, sea level is going to rise, some island country slightly above sea level may be affected.

Well, American does not bother about it, still poluting the air, China also the same...only Europe waken up..Originally posted by ndmmxiaomayi:On the other hand, other countries get warmer.

That why I still insisted that we should go for "Green" and go for energy efficiency. Less polution, more efficiency, saving energy, save money, save life...etc.
Well have to kiss Holland goodbye and maybe Japan too. -
China is doing something, but well, greed is the key word. A lot of money gets pumped in, but money don't know go where liao.Originally posted by king108:Well, American does not bother about it, still poluting the air, China also the same...only Europe waken up..

"Green" energy is hard to implement, many still think it is expensive. From what I see, they do seem expensive on the surface, but lasts longer and thereby keeping costs low.
Well, Singapore might be the next to go if enough sea level is rised. -
c16 was asking for it lah. turn left nvr signal or check blind spot..

Chinese do alot on surface only.."Green" energy is no too expensive, the problem is the control like what you mentioned .- money flow.Originally posted by ndmmxiaomayi:China is doing something, but well, greed is the key word. A lot of money gets pumped in, but money don't know go where liao.

Please to jump ship then, singapore is flat. -
Not holland my Uncle live there if anything happen to him i am going to eat the ice like its icecream or take it make ice kachangOriginally posted by ndmmxiaomayi:On the other hand, other countries get warmer.

I can imagine another iceman was found before you finished half the amount of ice..Originally posted by NewAge:Not holland my Uncle live there if anything happen to him i am going to eat the ice like its icecream or take it make ice kachang
