Some glaciers on the perimeter of West Antarctica are receiving increased heat from deep, warm ocean currents, which melt ice from the grounding line, releasing the brake and causing the glaciers to flow and shed icebergs into the ocean more quickly.

When floating ice shelves disintegrate, they reduce the resistance to glacial flow and thus allow the grounded glaciers they were buttressing to significantly dump more ice into the ocean, raising sea levels.

Since ice shelves act like plugs, removing them lets inland glaciers flow faster into the ocean, and that will raise sea levels.

At the grounding line, the ice detaches from the bedrock and juts out into the water as a kind of floating ledge, or ice shelf, which helps to stabilize the glacier and hold back the flow of ice behind it.

In recent years, the flow of these glaciers into the ocean has largely accelerated (red), which exacerbates melting.

Now, warming seawater intruding underneath has loosened the glaciers» grip on bedrock, speeding their flow toward the sea and causing increasing amounts of ice to break off into the ocean.

Glaciers around the world are melting and contributing to sea level rise, but scientists still don't quite understand how exactly glaciers give birth to icebergs as they flow into the ocean and lGlaciers around the world are melting and contributing to sea level rise, but scientists still don't quite understand how exactly glaciers give birth to icebergs as they flow into the ocean and lglaciers give birth to icebergs as they flow into the ocean and lose ice.

All told, if the eastern and western Antarctic ice shelves were to melt completely, they would raise sea levels by as much as 230 feet (70 meters); the collapse of smaller shelves like Larsen B has sped up the flow of glaciers behind them into the sea, contributing to the creeping up of high tide levels around the world.

Most Antarctic glaciers flow straight into the ocean in deep submarine troughs, the grounding line is the place where their base leaves the sea floor and begins to float.

CLIMATE CALAMITIES As ice shelves on the Southern Antarctic Peninsula weaken, glaciers flow faster into the sea.

A glaciologist rather than a biologist, he wanted to investigate a question critical to climate change: Do subglacial rivers and lakes lubricate the movement of ice over land — and might they somehow accelerate a glacier's flow into the ocean, triggering rapid sea level rise?

Snow on the glaciers is melting, causing more water to flow into valley, and this means more water for irrigation.

Two new reports have traced the effects of the collapse on the continent's remaining glaciers and found that they are flowing ever faster into the surrounding Weddell Sea.

As a result, the ice shelf is likely to both thin and flow faster, the researchers note — and eventually, that could allow the glacier to slide into the sea.

That glacier is a coastal system that flows into the Gulf of Alaska.

«As the glacier's calving front retreats into deeper regions, it loses ice — the ice in front that is holding back the flow — causing it to speed up,» Joughin clarifies.

This means that, even though the glacier is flowing towards the coast and carrying more ice into the ocean, its calving front is actually retreating.

«If that happens, the glacier's flow could be significantly destabilized, causing it to discharge even more ice into the ocean,» he said.
