This study was designed to describe the occurrence and distribution of Stomiidae along the Brazilian central coast. Three oceanographic cruises were made in the Brazilian central coast during the spring/1998, winter/1999 and autumn/2000. Stomiid larvae were very rare in the samples, occurring in 13% of the sampled stations. A total of 102 stomiid larvae were collected representing 11 species, some of which could only be identified to genus: Aristostomias sp., Astronesthes sp., Bathophilus sp., Eustomias sp., Melanostomias sp., Stomias sp., Chauliodus sloani, Flagellostomias boureei, Photonectes mirabilis, Photostomias guernei and Stomias affinis. All species identified have already been recorded from the Brazilian coast as adults, except for P. guernei, first recorded in this study. Most taxa were distributed both in the northern and southern regions of the study area, including the banks of the Vitória-Trindade Ridge. Stomias sp. was the most abundant taxon among all groups and was widely distributed along the study area. The species C. sloani and F. boureei were only collected in the south and north regions, respectively.

Set Up

Results of the basic model configuration of the REMO project, a Brazilian approach towards operational oceanography, are discussed. This configuration consists basically of a high-resolution eddy-resolving, 1/12 degree model for the Metarea V, nested in a medium-resolution eddy-permitting, 1/4 degree model of the Atlantic Ocean. These simulations performed with HYCOM model, aim for: a) creating a basic set-up for implementation of assimilation techniques leading to ocean prediction; b) the development of hydrodynamics bases for environmental studies; c) providing boundary conditions for regional domains with increased resolution. The 1/4 degree simulation was able to simulate realistic equatorial and south Atlantic large scale circulation, both the wind-driven and the thermohaline components. The high resolution simulation was able to generate mesoscale and represent well the variability pattern within the Metarea V domain. The BC mean transport values were well represented in the southwestern region (between Vitória-Trinidade sea mount and 29S), in contrast to higher latitudes (higher than 30S) where it was slightly underestimated. Important issues for the simulation of the South Atlantic with high resolution are discussed, like the ideal place for boundaries, improvements in the bathymetric representation and the control of bias SST, by the introducing of a small surface relaxation. In order to make a preliminary assessment of the model behavior when submitted to data assimilation, the Cooper & Haines (1996) method was used to extrapolate SSH anomalies fields to deeper layers every 7 days, with encouraging results.
