The Pará River estuary is a complex and special system in amazon continental shelf, with micro mesoscale physical processes generated by forces of different sources (e.g., astronomical tides river discharge). In this study, the main semidiurnal (M2) overtide (M4) components were analyzed quantifying distortions degrees identifying tidal asymmetries estuary. Two submersible gauges moored to measure water level. One on right margin (point #RG) another left (#LF) recorded measurements 6 months...

Abstract Despite the importance of jellyfish in marine ecosystems, many basic biological and ecological aspects remain understudied, especially tropical regions. Here, we report on scyphozoan distribution ecology to Amazon coast for first time, adding records Chrysaora lactea, Lychnorhiza lucerna Stomolophus fritillarius. We also review three species whole Brazilian coastline, describe temporal variability within an estuary length–weight relationships. The displayed a widespread coast. In...

A análise de variações na linha costa através imagens multitemporais permite a identificação processos erosivos e acrecionais em uma escala evolutiva. O objetivo desse trabalho foi avaliar as mudanças praias estuarinas do litoral amazônico (município Marapanim), entre os anos 1988 2016, por meio satélite Landsat. partir da digitalização linhas das Santa Maria, Marudá Crispim, nos referentes e, utilizado extensão Digital Shoreline Analysis (DSAS) no software ArcGis, possível realizar cálculos...
This paper describes the influence of tidal currents on sediment transport Amazonian equatorial beaches during extreme events. The study area (Salinópolis city) was divided into two sectors: western (Sampaio channel) and eastern (Atalaia Island). Field surveys were conducted in 2013 periods highest tides: April (the rainy season) October less season Spring Equinox). optical backscatter sensors (tide, turbidity, wave data) current meter (velocity field programmed to collect data every 0.1 60...
The research area of this paper is located at the estuary Amazon River (Brazil), more precisely river mouth (parallels 00° 30'N and 1° meridians 049° 00' W 050° 00'W). This presents results air movement analysis on surface atmospheric circulation over Mouth Amazonas River, salinity temperature measures as well measurements currents, carried out along a longitudinal section in navigation canal region Northern Bar (Barra Norte do Rio Amazonas) June 2006, during flood season quadrature tide....

The main objective of this article is to quantify the erosion and accretion rates on eastern margin middle Pará Estuary within 32 years (1987, 1993, 1999, 2004, 2008, 2013, 2019) with use remote sensing data Digital Shoreline Analysis System (DSAS) extension. These methodological procedures recently applied in Amazon region are effective search for intended results.
