The MVP and the FFCPT have been successfully integrated to arrive at a novel and tremendously efficient system to provide water column profile data and grain size analysis of the seafloor in support of numerous marine activities including science, hydrographic and naval applications. The MVP with FFCPT can make these measurements while the vessel is underway at 4-8 knots. The ability to collect...

Description of a new species of Diaptomidae (Crustacea, Copepoda, Calanoida) Notodiaptomus oliveirai is given from the material obtained at a reservoir at Barra Bonita, SP in 1992. The new species is very similar to Notodiaptomus henseni Dahl 1894 although both species can be found in the same locality, constituting two distinct populations. Notodiaptomus oliveirai seems to be endowed with grea...

The objectives of this project are; to demonstrate that hydrographic variability in shelf waters can be hind-cast, to a quantifiable degree, using a simple 1 dimensional physical model. To demonstrate that the model can be used to interpret the regional variability of ocean colour in terms of the mechanisms of physical forcing on phytoplankton growth. The effects of tidal front dynamics and the...

Cytogenetic data are presented for Astyanax altiparanae populations from three Brazilian hydrographic systems. The chromosomal data obtained in A. altiparanae support the hypothesis of diploid number conservation. However, small differences in the karyotype formula and number of nucleolar organizer regions were observed in these populations. The apparent karyotypical similarity among the studie...

The Atlantic meridional overturning circulation (AMOC) is central to the climate of by redistributing mass, heat, and freshwater. Hydrographic sections help monitor its strength at different latitudes, inverse box models provide estimates AMOC, freshwater transports. We have used all available hydrographic zonal 24.5°N 30°S over last 30 years conclude that single section agree with monthly outp...
