Distribution and Circulation of Labrador Sea Water
Labrador Sea Water Distribution Circulation
2009/2/8
Labrador Sea Water is the final product of the cyclonic circulation of Subpolar Mode Water in the open northern North Atlantic (McCartney and Talley, 1982). The temperature and salinity of the convect...
The Formation of Labrador Sea Water. Part II. Mesoscale and Smaller-Scale Processes
Labrador Sea Water Mesoscale Smaller-Scale Processes
2009/2/6
In a previous paper, Clarke and Gascard argued that the formation of Labrador Sea Water was taking place in a cyclonic gyre set up each winter in the western Labrador Sea.
Within the gyre and at it...
The Formation of Labrador Sea Water. Part I：Large-Scale Processes
Labrador Sea Water Large-Scale Processes
2009/2/6
Data obtained in the western Labrador Sea during March 1976 by Hudson are analysed to show that new Labrador Sea Water was being formed at this time. On the basis of hydrographic and moored current-me...
A Buoyancy Flux-Driven Cyclonic Gyre in the Labrador Sea
geostrophic equilibrium Buoyancy Flux-Driven Cyclonic Gyre Labrador Sea
2009/1/6
The generation mechanism for a wintertime cyclonic gyre in the western Labrador Sea, first observed by Clarke and Gascard, is studied by using simple theoretical models. It is shown that atmospheric c...
The Formation of Labrador Sea Water. Part III：The Evolution of Oxygen and Nutrient Concentration
Labrador Sea Water Oxygen Concentration Nutrient Concentration
2009/1/5
Oxygen, nutrient, and tritium concentrations observed in the western Labrador Sea in March 1976 during deep convective renewal of Labrador Sea water are analyzed to show how a newly formed water mass ...
Labrador Sea Water in the Eastern North Atlantic. Part II：Mixing Dynamics and the Advective–Diffusive Balance
Labrador Sea Water Mixing Dynamics Advective–Diffusive Balance
2008/12/11
Deep wintertime convection in the Labrador Basin produces Labrador Sea Water (LSW), which spreads throughout the North Atlantic. The LSW is not formed with constant characteristics but varies on decad...
Labrador Sea Water in the Eastern North Atlantic. Part I：A Synoptic Circulation Inferred from a Minimum in Potential Vorticity
Labrador Sea Water Potential Vorticity Synoptic Circulation
2008/12/11
A synoptic distribution of Labrador Sea Water (LSW) in the eastern North Atlantic is determined from a regularly sampled, but sparse (3° resolution), survey covering 39° to 54°N, 11° to 34°W during sp...
Modeling the Mean Circulation of the Labrador Sea and the Adjacent Shelves
Mean Circulation Adjacent Shelves Labrador Sea
2008/12/10
A linear three-dimensional diagnostic model is used to study several aspects of the mean circulation of the Labrador Sea and the adjacent shelves: volume transport, three-dimensional structure of curr...
Observing Deep Convection in the Labrador Sea during Winter 1994/95
Observing Deep Convection Labrador Sea Winter
2008/7/17
A 12-month mooring record (May 1994–June 1995), together with accompanying PALACE float data, is used to describe an annual cycle of deep convection and restratification in the Labrador Sea. The moori...
Experiments with a suite of North Atlantic general circulation models are used to examine the sources of eddy kinetic energy (EKE) in the Labrador Sea. A high-resolution model version (112°) quantitat...
Effects of Wind on Convection in Strongly and Weakly Baroclinic Flows with Application to the Labrador Sea
Baroclinic Flows Labrador Sea
2008/6/13
Large buoyancy loss driving deep convection is often associated with a large wind stress that is typically omitted in simulations of convection. Here it is shown that this omission is not justified wh...
How Does Labrador Sea Water Enter the Deep Western Boundary Current
Labrador Sea Water Enter Western Boundary Current
2008/6/9
Labrador Sea Water (LSW), a dense water mass formed by convection in the subpolar North Atlantic, is an important constituent of the meridional overturning circulation. Understanding how the water mas...

Labrador Sea Boundary Currents Irminger Sea Water
2008/6/4
The general circulation of the Labrador Sea is studied with a dataset of 53 surface drifters drogued at 15 m and several hydrographic sections done in May 1997. Surface drifters indicate three distinc...
Labrador Sea Water: Pathways, CFC Inventory, and Formation Rates
Labrador Sea Pathways CFC Inventory Formation Rates
2008/6/4
In 1997, a unique hydrographic and chlorofluorocarbon (CFC: component CFC-11) dataset was obtained in the subpolar North Atlantic. To estimate the synopticity of the 1997 data, the recent temporal evo...
Rates and Mechanisms of Water Mass Transformation in the Labrador Sea as Inferred from Tracer Observations

2008/6/4
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 fie...
