Newly-設立する 深い Icelandic 現在の could 'save' North America and Europe from 気候 change
- The North Icelandic Jet 料金d a 巨大（な） pattern known as the '広大な／多数の／重要な ocean conveyor belt', which 規制するs North American and European 気候s
A newly-discovered 深い, 冷淡な 現在の flowing off アイスランド's coast may mean the North 大西洋 is いっそう少なく 極度の慎重さを要する to 気候 change than 以前 thought.
The North Icelandic Jet 料金d the 大西洋 Meridional Overturn ing 循環／発行部数 - or AMOC - a 巨大（な） pattern known as the '広大な／多数の／重要な ocean conveyor belt', which 規制するs North American and European 気候s.
Scientists had 以前 believed that most of the 冷淡な water that formed that 深い south-flowing stream （機の）カム from off the Greenland coast and was made up of fresh glacier-melt water.

However, the North Icelandic Jet appears to 与える／捧げる more to the deeper part of the AMOC than the Greenland 現在の does, によれば scientists.
The 'conveyor belt' 現在の was introduced in the Al 血の塊／突き刺す 環境の film An Inconvenient Truth, and carries warm surface water from the 熱帯の 大西洋 toward the 北極の.

In the 過程, the water warms the 空気／公表する in high latitudes, then 冷静な／正味のs, 沈むs and returns に向かって the 赤道, flowing as a 深い stream at lower ocean depths.
Because fresh water 凍結するs at a higher 気温 than salt water, these specialists 示唆するd that this fresh water from glaciers and other warming-関係のある phenomena would get into the North 大西洋, where it could 凍結する and 妨げる the water from 沈むing to （不足などを）補う the 底（に届く） of the conveyor belt.
If that happened, and the 大西洋 Meridional Overturning 循環／発行部数 was 混乱に陥れる／中断させるd or slowed at the place in the far north where the warm water at the surface 冷静な／正味のs and 沈むs - called the overturning - it could 結局 lead to a colder Northern 半球.
熟考する／考慮する co-author Robert Pickart, of the 支持を得ようと努めるd 持つ／拘留する 海洋学の 会・原則, said: '現在の thinking 競うs that 増加するd fresh water 配達するd to the North 大西洋, 予定 to melting ice and 増加するd precipitation under a warming 気候, will slow 負かす／撃墜する or 停止（させる） the overturning of the AMOC.'
This might not be the 事例／患者 if the overturning occurs in the 内部の of the アイスランド Sea, which 料金d the North Icelandic Jet, Dr Pickart 追加するd.
'It is not 信じられない that this open-ocean 過程 is いっそう少なく 極度の慎重さを要する to fresh water 軍隊ing than the presently 受託するd 機械装置 ... which might lead one to 推測する that the deepest part of the overturning may be いっそう少なく 極度の慎重さを要する to 気候 change,' he said.

The 存在 of the North Icelandic Jet was 嫌疑者，容疑者／疑うd for １０年間s but was only 確認するd recently by Icelandic 研究員s using underwater velocity 測定s taken from a ship.
The 現在の cannot be seen by 衛星s or （悪事，秘密などを）発見するd by its 気温 or salinity, but it does move a bit faster than the surrounding water, Pickart said.
Pickart and 研究員s from Norway and アイスランド don't know whether the North Icelandic Jet flows year 一連の会議、交渉／完成する or how it 変化させるs with time.
They are beginning a 研究 voyage this week to （軍隊を）展開する，配備する 海洋学の 器具s to 直接／まっすぐに 手段 the North Icelandic Jet over the course of a 十分な year to try to 人物／姿／数字 out where and how this 現在の forms.
The 研究 is published in the 定期刊行物 Nature Geoscience.
