High-resolution sea surface reconstructions off Cape Hatteras over the last 10 ka
[1] This study presents high-resolution foraminiferal-based sea surface temperature, sea surface salinity and upper water column stratification reconstructions off Cape Hatteras, a region sensitive to atmospheric and thermohaline circulation changes associated with the Gulf Stream. We focus on the last 10,000 years (10 ka) to study the surface hydrology changes under our current climate conditi...
متن کاملThe 8200 year B.P. event in the slope water system, western subpolar North Atlantic
[1] Stable isotope, trace metal, alkenone paleothermometry, and radiocarbon methods have been applied to sediment cores in the western subpolar North Atlantic between Hudson Strait and Cape Hatteras to reveal the history of climate in that region over the past 11 kyr. We focus on cores from the Laurentian Fan, which is known to have rapid and continuous accumulation of hemipelagic sediment. Alt...
متن کاملMesoscale Variability in the Labrador Sea
My immediate objective is to understand the interactions between convection and mesoscale circulation, in order to quantify the in uence of convective events on the large scale circulation. Such interactions include: (a) The lateral mixing generated by baroclinic instability and geostrophic eddy interactions. How e cient are lateral mixing processes in convective regions? Can these processes ac...
متن کاملRates and Mechanisms of Water Mass Transformation in the Labrador Sea as Inferred from Tracer Observations*
Time series of hydrographic and transient tracer (3H and 3He) observations from the central Labrador Sea collected between 1991 and 1996 are presented to document the complex changes in the tracer fields as a result of variations in convective activity during the 1990s. Between 1991 and 1993, as atmospheric forcing intensified, convection penetrated to progressively increasing depths, reaching ...
متن کاملSimultaneous mooring-based measurements of seawater CO, and 0, of’f Cape Hatteras, North Carolina
We deployed CO, and 0, sensors on the U.S. continental shelf off Cape Hatteras, North Carolina, during late summer 1994. A continuous 32-d gas record was obtained at 20 m in 25 m of water, below the thermocline for most of the period. Analysis of the correlation between CO, and 0, indicates that biological and advective processes dominated the gas variability, with small or insignificant fluxes...
