Sentences with phrase «increases calving»

Increased basal melting also increases calving of the floating ice shelf and the loss of buttressing power that inhibits the glaciers» seaward flow.

These were selected for their positive traits for the dairy cow, such as fertility, shorter gestation and increased calving ease, and their positive traits for producing an efficient beef animal, such as health, growth rate, feed efficiency and carcase merit.

Releasing a huge iceberg, by itself, is a normal process, unrelated to warming, but increased calving may occur in the future if the ice shelf continues to thin, which would make it susceptible to plate bending and hydrofracture processes21.

Thicker ice in deeper water drives increased calving, increased ice discharge, and further grounding - line recession in a positive feedback loop2, 3.

This will produce a vertical torque, especially at times of high tides (see my # 3), resulting in increased calving.

The end result is the glaciers accelerate seaward, causing dynamic thinning, increased calving, and a large loss of ice mass that continues until a new equilibrium is established.

So for land ice, more snow falls on Antarctica, but the land ice mass is dropping due to increased calving rates.

Not exact matches

Warnings for shipping Molnia said a system for such tracking of glaciers could provide important warning for shipping in the region as calving, and the formation of icebergs, increases.

A new study shows how huge influxes of fresh water into the North Atlantic Ocean from icebergs calving off North America during the last ice age had an unexpected effect — they increased the production of methane in the tropical wetlands.

Antarctica holds about 60 percent of the world's fresh water, so any pattern of increased melting and calving has profound implications for cities and countries across the world.

Around that time, a string of especially warm summers triggered increased melting and calving events, which have continued to the present day.

Kevin, the real reason that sea ice volume will likely not reach zero any time soon is that calving from Greenland and from the Canadian archipelago will continue and will likely increase.

So a 3-fold increase in output glacier velocity does not count as «extensive sustained calving»?

There has also been an alarming increase in the number of photographs of meltwater draining into a moulin somewhere on the GIS, often near Swiss Camp (35 km inland from the calving front).

If there were truly an increase in glacier calving events (due to warming or any other cause), the best evidence would be an increase in iceberg numbers starting in 1900 for example.

If snowfall increases (as in some models), the mass of ice in Greenland and Antarctica may increase, even if there is more melting and calving of icebergs at the edges.

Though it is unclear how much the Glacier could speed up following the most recent calving, researchers expect another increase, possibly greater than that brought on by the 2010 event.

The article claimed that earthquakes were caused by icebergs calving off the Helheim Glacier, and that these were increasing because of increased outflow from this glacier.

The glacier is still quite thick and should slow its retreat once the bedrock slope begins to increase, and the minor lake calving ceases.

Detecting glacialquakes is important because glaciers appear to accelerate after large calving events.2 The frequency of glacialquakes — which has been rising since the late 1990s — has increased particularly since 2002.3 In fact, the number of quakes in 2005 was twice that of 2001.1 In late summer of 2005, glacial seismic activity was almost five times greater than in the winter months — most likely owing to seasonal changes in temperature.1, 3

The slope of the glacier, its upglacier velocity and the height of the calving face strive to increase flow.

Although glaciers calving into the ocean cause much of the ice loss in Greenland, other research cited in the study shows that the majority of ice loss in recent years is from increased surface melt and runoff.

-- First we increase the greenhouse gases — then that causes warming in the atmosphere and oceans — as the oceans warm up, they evaporate more H2O — more moisture in the air means more precipitation (rain, snow)-- the southern hemisphere is essentially lots of water and a really big ice cube in the middle called Antarctica — land ice is different than sea ice — climate models indicated that more snowfall would cause increases in the frozen H2O — climate models indicated that there would be initial increases in sea ice extent — observations confirm the indications and expectations that precipitation is increasing, calving rates are accelerating and sea ice extent is increasing.

Kevin, the real reason that sea ice volume will likely not reach zero any time soon is that calving from Greenland and from the Canadian archipelago will continue and will likely increase.

Or what if stronger tides increased glacial flow or calving at the coasts, or tidal currents openned up gaps in sea ice covering by piling sea ice against islands, thus affecting albedo and surface heat fluxes?

Before we had GRACE satellite measurements, the consensus was that the Antarctic would be in mass balance for a long time, with increased iceberg calving offset by increased snowfall in the interior.

Two decades ago, the Greenland ice sheet was in approximate balance - ice loss at the edges as glaciers calved into the ocean was balanced by ice gain in the interior from increased snowfall.
