Chemical diversity and spatial variability in myriad lakes in Nhecolaˆndia in the Pantanal wetlands of Brazil
Chemical diversity spatial variability Pantanal wetlands
2014/4/2
Nearly 15,000 shallow, saline or freshwater lakes and ponds coexist in close proximity in the Nhecolaˆndia, a
24,000 km2
subregion of the Pantanal wetland in Brazil. This study aims to understa...
Asymptotic Analysis of the Agulhas and Brazil Current Systems
Asymptotic Analysis Agulhas Brazil Current Systems
2009/2/7
An asymptotic analysis is carried out of a linear and a nonlinear transport model of the large-scale wind-driven ocean circulation in the subtropical region of the Atlantic and Indian Oceans. The comp...
Tidal and Low-Frequency Currents Near the Shelf-Break：Northeastern Coast of Brazil
Low-Frequency Currents Shelf-Break Brazil
2009/2/6
Time series of a 40-day (13 March-23 April 1979) wind and current observational experiment are analyzed. The wind data originated from the Fortaleza Airport Weather Station (Ceará, Brazil), and the cu...
The Flow of Antarctic Bottom Water into the Brazil Basin
Antarctic Bottom Water Brazil Basin
2008/12/19
The total transport of Antarctic Bottom Water across the Rio Grande Rise, including the western boundary, the Vema Channel, and the Hunter Channel is estimated from hydrographic measurements across th...
On the Separation of the Brazil Current from the Coast
low transport Brazil Current Coast
2008/12/17
A series of numerical experiments, using analytical and numerical models, leads to the conclusion that the separation of the Brazil Current from the coast can be related to the northward momentum of t...
In late austral summer 1991 a cyclonic thermocline eddy was detected in the subtropical western South Atlantic off the Brazilian shelf near the city of Vitória. This Vitória eddy was tracked for 55 da...
Annual Cycle and Variability of the North Brazil Current
Annual Cycle North Brazil Current low-frequency variability
2008/11/6
Current meter observations from an array of three subsurface moorings located on the Brazil continental slope near 4°N are used to describe the annual cycle and low-frequency variability of the North ...
One of the major objectives of the Deep Basin Experiment, a component of the World Ocean Circulation Experiment, was to quantify the intensity and spatial distribution of deep vertical mixing within t...
Circulation and Variability at the Southern Boundary of the Brazil Basin
Southern Boundary Brazil Basin
2008/7/8
As a contribution to the WOCE Deep Basin Experiment, an array of current meters with individual record lengths exceeding 1½ years was set across the southern boundary of the Brazil Basin betwee...
Buoyancy Forcing by Turbulence above Rough Topography in the Abyssal Brazil Basin
Buoyancy Forcing Turbulence Rough Topography Abyssal Brazil Basin
2008/6/4
Observations of turbulent dissipation above rough bathymetry in the abyssal Brazil Basin are presented. Relative to regions with smooth bathymetry, dissipation is markedly enhanced above rough topogra...
Spatio-temporal geochemistry of mercury in waters of the Tapajo′s and Amazon rivers, Brazil
he Tapajo′s Amazon rivers
2014/6/9
Spatial and temporal variations of mercury (Hg) concentrations were monitored in the surface waters from the
lower portion of the Tapajo′s River, the Arapiuns River, its principal tributary, and the ...
