The global climate models do a good job of simulating the process of sea ice formation over large areas in the open ocean.

Coastal sea ice formation takes place on relatively small scales, however, and is not captured well in global climate models, according to scientists at the University of California, Santa Cruz, who conducted the study.

What the climate models were missing, she said, was the strong brine production from sea ice formation in the Bering Sea.

However, the geologist goes on to explain, «That being said, a chronological sequence of extremely extended thick ice sheets (similar to what Jakobsson et al. have postulated) followed by sea ice formation with polynyas seems to be possible, as the initial results of our own investigations on the southern Lomonosov Ridge have shown.

The upper part of the modern Arctic Ocean is flushed by North Atlantic currents while the Arctic's deep basins are flushed by salty currents formed during sea ice formation at the surface.

The increasing size of the Sahara Desert, reduced arctic sea ice formation in winter and summer, desertification of temperate lands, droughts and more frequent extreme weather events have all been linked to anthropogenic climate change.

A recent study investigates the drivers of changes in deep ocean circulation across a range of modern and Last Glacial Maximum (~ 21000 years ago) climate modeling simulations, revealing biases in Antarctic sea ice formation.

«As the climate gets warmer, we could see reduced sea ice formation in the Sea of Okhotsk and the Arctic.

The Bering Sea is less important during warm periods like today, when wintertime sea ice formation in the Sea of Okhotsk generates most of the North Pacific Intermediate Water.

Arctic sea ice formation feeds global ocean circulation.

«There must have been significant melt - back of sea ice each summer even at the height of the last ice age to have sea ice formation on the shelves each year.

Understanding such processes, though, is «critically important to understanding the climate of the earth» because of the way sea ice formation works as the initial driver of the global ocean «conveyor belts», Dr Lieser said.

The researchers show that models simulating strong LGM sea ice formation also exhibit enhanced stratification and a shallower Atlantic Meridional Overturning Circulation (AMOC), largely consistent with the geological evidence.

The extremely anomalous sea ice formations along the polar shoreline shown above are a harbinger of aggressive chemical ice nucleation programs being carried out by the climate engineers.

Coastal sea ice formation may be important to future climate change because the arctic and subarctic regions are warming at twice the rate of other parts of the world,» said first author Karla Knudson, a graduate student in Earth and planetary sciences at UC Santa Cruz.

In contrast, once the Antarctic refrigerator was established, cold salty brine was now extruded during sea ice formation.

This analysis indicates that most of the apparent inconsistencies between different models can be reconciled and attributed to differing (and likely insufficient) Antarctic sea ice formation.

But the same process of sea ice formation and brine production along coastal shelves plays a critical role wherever it occurs.

Top panels: 50 % annual sea ice concentration (dashed blue line) and buoyancy fluxes, where negative values (blue shading) are associated with sea ice formation; note that these areas expand equatorward in the LGM simulation.

An unprecedented analysis of North Pacific ocean circulation over the past 1.2 million years has found that sea ice formation in coastal regions is a key driver of deep ocean circulation, influencing climate on regional and global scales.

However, I am not optimistic — the specifics of the small scale physics (aerosol indirect effects on clouds, sea ice formation, soil hydrology etc.) are so heterogeneous that I don't see how you can do without calculating the details.

The study, published in the journal Nature Geosciences, suggests that the change of phase of the Interdecadal Pacific Oscillation (IPO) from positive to negative, or vice versa, could initiate chain reaction of climate impact that may affect the sea ice formation in the Antarctic region.

This sea ice formation creates cold, dense, salty water that sinks to the seafloor and forms very dense Antarctic bottom water.

Extremely cold (katabatic) winds blowing off the Antarctic Ice Sheet, push water and sea ice offshore, contributing to high rates of sea ice formation.

This year's sea ice formation is what Neven calls a «deat cat bounce»; usually the years of most severe melt have been followed by a recovery because there is more fresh water floating on the surface, enhancing freezing.

However, the exact timing and extent of sea ice formation and continental glaciation in the Arctic during the Pliocene remains uncertain (Zachos et al., 2008).
