, 2017 Much has been written, literally for centuries, on the origins of Natives in the Americas and still there is no consensus on the date or even the embarkation point of the people who first populated this continent. In this collection of essays from Indian Country Today Media, Historian Alexander Ewen (Purepecha) explores not only the ever-controversial ...

Variability, trends and predictability of seasonal sea ice retreat and advance in the Chukchi Sea [PDF]
, 2016 As assessed over the period 1979–2014, the date that sea ice retreats to the shelf break (150 m contour) of the Chukchi Sea has a linear trend of −0.7 days per year. The date of seasonal ice advance back to the shelf break has a steeper trend of about +1.

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract Global ocean circulation regulates climate and has undergone significant changes over the Cenozoic. Today, the Atlantic Meridional Overturning Circulation (AMOC) is driven by North Atlantic Deep Water (NADW) formation and Southern Ocean upwelling.

Bering Strait throughflow and the thermohaline circulation [PDF]
Geophysical Research Letters, 2005 In this study, we employ a global coupled climate model to show that the Bering Strait is important to the variations of the thermohaline circulation. Three experiments are analyzed, a present day control run, and two freshwater hosing runs. Results show that as the thermohaline circulation weakens due to freshwater forcing in the northern North ...

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract In this study, we investigate the impacts of the eastern Arctic water mass properties on the Atlantic Meridional Overturning Circulation (AMOC) and the Beaufort Sea thermal structure by constraining the eastern Arctic in a coupled model using the observed hydrographic climatology.

The Pacific‐Atlantic seesaw and the Bering Strait [PDF]
Geophysical Research Letters, 2012 Paleo proxy data and previous modeling studies both indicate that the massive discharge of icebergs into the North Atlantic may have led to a (nearly) collapsed Atlantic meridional overturning circulation (AMOC), resulting in a seesaw‐like climate change between the North Pacific and North Atlantic, with a warming in the former and a cooling in the ...
