“…Marshall et al. (2021) found only subtle evidence of dissolution at the BIS location during Heinrich stadial 1 due to low sample resolution, however, the authors did not exclude the possibility of intense dissolution caused by an increased terrestrial organic carbon flux (Gibb et al., 2014). Enhanced carbonate dissolution during Heinrich Stadials in the Labrador Sea and the North Atlantic is also supported by model studies forced by the fresh water inflow in the North Atlantic region that suggest significant decrease in carbonate burial flux (Chikamoto et al., 2008).…”

The Atlantic Meridional Overturning Circulation (AMOC) plays an important role in regional and global climate variability. Driven by the heat exchange between the atmosphere and the ocean its surface branch transports heat from equatorial regions to high latitudes thereby affecting the climate in the entire Northern Hemisphere (cf., Dickson et al., 1988;Dommenget & Latif, 2002;Gulev et al., 2001). Many studies have focused on the processes controlling present and past Atlantic deep water convection and water mass formation to improve our understanding of the factors driving AMOC variability and to achieve more realistic climate predictions (

The high rate of biological productivity in the North Atlantic is stimulated by the advective supply of nutrients into the region via the Gulf Stream (nutrient stream). It has been proposed that the projected future decline in the Atlantic Meridional Overturning Circulation (AMOC) will cause a reduction in nutrient supply and resulting productivity. In this work, we examine how the nutrient stream changed over the Younger Dryas climate reversal that marked the transition out of the last ice age. Gulf Stream nutrient content decreased, and oxygen content increased at the Florida Straits during this time of weakened AMOC. The decreased nutrient stream was accompanied by a reduction in biological productivity at higher latitudes in the North Atlantic, which supports the link postulated in theoretical and modeling studies.
