Gulf Stream density structure and transport during the past millennium

  title={Gulf Stream density structure and transport during the past millennium},
  author={David C. Lund and Jean Lynch‐Stieglitz and William B. Curry},
The Gulf Stream transports approximately 31 Sv (1 Sv = 106 m3 s-1) of water and 1.3 × 1015 W of heat into the North Atlantic ocean. The possibility of abrupt changes in Gulf Stream heat transport is one of the key uncertainties in predictions of climate change for the coming centuries. Given the limited length of the instrumental record, our knowledge of Gulf Stream behaviour on long timescales must rely heavily on information from geologic archives. Here we use foraminifera from a suite of…

Recent changes to the Gulf Stream causing widespread gas hydrate destabilization
This analysis suggests that changes in Gulf Stream flow or temperature within the past 5,000 years or so are warming the western North Atlantic margin by up to eight degrees Celsius and are now triggering the destabilization of 2.5 gigatonnes of methane hydrate (about 0.2 per cent of that required to cause the PETM).
Florida Straits density structure and transport over the last 8000 years
[1] The density structure across the Florida Straits is reconstructed for the last 8000 years from oxygen isotope measurements on foraminifera in sediment cores. The oxygen isotope measurements
Evidence from the Florida Straits for Younger Dryas ocean circulation changes
[1] The waters passing through the Florida Straits today reflect both the western portion of the wind‐driven subtropical gyre and the northward flow of the upper waters which cross the equator,
Decadal variability of sea surface temperatures off North Iceland over the last 2000 years
Annually resolved North Atlantic marine climate over the last millennium
It is demonstrated that solar and volcanic forcing coupled with ocean circulation dynamics are key drivers of climate variability over the last millennium and variability in the sub-polar North Atlantic leads changes in Northern Hemisphere surface air temperatures at multi-decadal timescales.

Solar forcing of Florida Straits surface salinity during the early Holocene
[1] Previous studies showed that sea surface salinity (SSS) in the Florida Straits as well as Florida Current transport covaried with changes in North Atlantic climate over the past two millennia.
Tropical cyclone activity and western North Atlantic stratification over the last millennium: a comparative review with viable connections
Tropical cyclones (TC) are recognized to modify the thermal structure of the upper ocean through the process of vertical mixing. Assessing the role this mixing plays in the overall stratification of

Weaker Gulf Stream in the Florida Straits during the Last Glacial Maximum
As it passes through the Florida Straits, the Gulf Stream consists of two main components: the western boundary flow of the wind-driven subtropical gyre and the northward-flowing surface and
Florida Current surface temperature and salinity variability during the last millennium
surface water (d 18 Ow) near Dry Tortugas increased 0.4% during the course of the Little Ice Age (LIA) (� 1200– 1850 A.D.), equivalent to a salinity increase of 0.8–1.5. On the Great Bahama Bank,
Late Holocene variability in Florida Current surface density: Patterns and possible causes
[1] Planktonic foraminiferal δ18O time series from three well-dated, high sedimentation rate cores near the Florida Keys (24.4°N, 83.3°W) exhibit repeated centennial to millennial-scale oscillations
Late Holocene variability of upper North Atlantic Deep Water temperature and salinity

The Cariaco Basin record exhibits strong correlations with climate records from distant regions, including the high-latitude Northern Hemisphere, providing evidence for global teleconnections among regional climates.

Sea surface temperature (SST), salinity, and flux of terrigenous material oscillated on millennial time scales in the Pleistocene North Atlantic, but there are few records of Holocene variability.
