Overturning circulation, nutrient limitation, and warming in the Glacial North Pacific

https://advances.sciencemag.org/content/6/50/eabd1654

Abstract

Although the Pacific Ocean is a major reservoir of heat and CO₂, and thus an important component of the global climate system, its circulation under different climatic conditions is poorly understood. 

Here, we present evidence that during the Last Glacial Maximum (LGM), the North Pacific was better ventilated at intermediate depths and had surface waters with lower nutrients, higher salinity, and warmer temperatures compared to today.

评论：A和B比，B=today，A呢？Maybe we can use “compared to today’s”?

Modeling shows that this pattern is well explained by enhanced Pacific meridional overturning circulation (PMOC), which brings warm, salty, and nutrient-poor subtropical waters to high latitudes. 

Enhanced PMOC at the LGM would have lowered atmospheric CO₂—in part through synergy with the Southern Ocean—and supported an equable regional climate, which may have aided human habitability in Beringia, and migration from Asia to North America.
