چکیده

A Data-Interpolating Variational Analysis in n-dimensions was used to describe a potential temperature distribution the bottom layer of fracture zones Mid-Atlantic Ridge at 7–8°N. This analysis based on new digital terrain model obtained by supplementing STRM15+ bathymetry data with multibeam echo sounding from 33rd cruise research vessel
 Akademik Nikolaj Strakhov (2016) and oceanological World Ocean Database, supplemented CTD profiles reversing thermometer measured scientific cruises Shirshov Institute Oceanology, Russian Academy Sciences 2014–2016. 2D near-bottom study area calculated analysis. The allows us propose Antarctic Bottom Water propagation pattern through Doldrums, Vernadsky, Pushcharovsky zones. It is shown that water warms up when passing 1.4°C Fracture Zone 1.6–1.7°C Vernadsky Zone. fractures propagates two directions. Northernly, it Doldrums Zone, where its reaches about 1.9–2.0°C. Easterly, flows along raising 1.8–2.0°C. We absence Water's overflow less than 1.8°C East Atlantic area.

The spreading of Antarctic bottom water in the tropical Atlantic

Hydrographic and tracer [chlorofluorocarbon (CFC), component F11] data in the tropical Atlantic off Brazil taken in spring 1994 are used to describe the development of the water mass characteristics of Antarctic Bottom Water (AABW) between 10°S and 11°N. To compute the AABW transports, geostrophic computations and directly measured velocity fields are combined. Velocity profiles were measured w...

Fracture zones in the Mid Atlantic Ridge lead to alterations in prokaryotic and viral parameters in deep-water masses

We hypothesized that mixing zones of deep-water masses act as ecotones leading to alterations in microbial diversity and activity due to changes in the biogeochemical characteristics of these boundary systems. We determined the changes in prokaryotic and viral abundance and production in the Vema Fracture Zone (VFZ) of the subtropical North Atlantic Ocean, where North Atlantic Deep Water (NADW)...

determination of maximal singularity free zones in the workspace of parallel manipulator

due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
