As espécies de peixes que ocorrem no estuário da Lagoa dos Patos (ELP) apresentam diferentes estratégias de desova que procuram otimizar um balanço entre condições ambientais locais e remotas, e seu ciclo de vida. O presente ...

Local expressions of climate change are threatening the capacity of coastal ecosystems to support goods and services valued by society on a global scale. As articulated in many international and national ocean policies, ...

Bathymetric, sedimentological and seabed acoustic backscatter data were integrated into a 3D GIS (Geographic Information System). 38 kHz echo sounders were used to collect data over 14,596 nautical miles during six fish ...

Some processes related to hydrodynamics, geomorphology and sediment movement represent coastal hazards and risks along the littoral of Rio Grande do Sul (RS) state in southern Brazil. The hazards imply in coastal erosion, ...

Whitemouth croaker (Micropogonias furnieri) single echoes, which represent single fishes, as well as entangling nets were recorded with a 200 kHz Hidrotrac echo sounder in the shallow waters of the Lagoa dos Patos, Rio ...

This paper characterizes major ion distributions and investigates whether groundwater exerts a major control on the chemical functioning of Mangueira Lagoon, a large (90 km long), shallow (*4–5 m deep), and fresh coastal ...

The distribution of mercury in sediments of the Patos Lagoon estuary and nearby coastal marine deposits has been investigated for the period 1998–2008. Polluted urban soils and coastal reclamation fills are the principal ...

In this study, we measured the mercury concentration in 27 different fish species with high commercial value. Samples were taken from a region characterized by the diversity of aquatic environments. Mercury concentration ...

We studied the distribution, bioavailability and speciation of copper in subtropical sandy soils exposed to long-term applications of copper-based fungicide. In the surface horizon of the contaminated soils, bioavailable ...

The present study aimed to demonstrate the effectiveness of the 5s rDNA gene for the identification of commercially-valuable species of cephalopod belonging to the families Loliginidae and Ommastrephidae. Our results ...

Arsenic levels (up to 130 mg kg−1) substantially exceeding the official threshold have recently been documented in beach and nearshore sediments along more than 50 km of coastline in the Brazilian state of Espírito Santo ...

The TRAIN-SEA-COAST Programme (TSC) was created in 1993 by the United Nations Division of Ocean Affairs and the Law of the Sea. The overall goal of the Programme is capacity building at the local level. The Programme is ...

A concentração de fluoreto foi determinada, através do método potenciométrico, com eletrodo íon seletivo, na água da chuva e na água subterrânea, no município de Rio Grande. Os teores de fluoreto na água da chuva variaram ...

O presente trabalho pretende analisar alguns aspectos conjunturais na perspectiva histórica e política da gestão pública ambiental, apontando sua evolução no quadro legal do Estado brasileiro, e o espaço da participação ...

Ionic contents (Na+,K+and Cl-) of plasma and gallbladder bile (GB) of juveniles silver catfish, Rhamdia quelen (156.1±0.2g, 28.2±0.3cm), were determined in three different times(0,6 and 24h)after exposureto: a)control ...

In this study we verified data of water temperatures collected by CORSAN-RS from 1996 to 2004 in several cities of the state of Rio Grande do Sul, southern Brazil, and analyzed the possibility of raising the most cultivated ...

Strontium and barium incorporation into otoliths was compared between whitemouth croaker, Micropogonias furnieri, collected from an entrapped freshwater population (Mirim Lagoon) and a normal marine/estuarine population ...

Global ocean colour algorithms, used to extract chlorophyll concentration in the ocean surface, normally overestimate pigment values in coastal regions, due to optical interference of water components. The objective of ...

The shelf-break front formed between Argentinean shelf waters and the Malvinas Current(MC)flow shows a conspicuous band of high phytoplankton biomass throughout spring and summer, detected by ocean color sensors. That ...

We examine Weddell Sea deep water mass distributions with respect to the results from three different model runs using the oceanic component of the National Center for Atmospheric Research Community Climate System Model ...
