A novel Amazonian reef biome was discovered, encompassing large rhodolith and sponge beds under low light, oxygen, high POC.
This paper provides a description of the wave climate off Brazilian coast based on an eleven-year time series (Jan/1997-Dec/2007) obtained from NWW3 operational model hindcast reanalysis. Information about in waters is very scarce and mainly occasional short-term observations, present analysis being first covering such temporal spatial scales. To define climate, six sectors were defined analyzed along shelf-break: South (W1), Southeast (W2), Central (W3), East (W4), Northeast (W5) North...
Here we provide a broad overview of the Great Amazon Reef System (GARS) based on first-ever video surveys region. This footage supports four major hypotheses: 1) GARS area may be six times larger than previously suggested (up to 56,000 km2); 2) extend deeper 220 m); 3) is composed greater complexity and diversity habitats recognized (e.g. reef platforms, walls, rhodolith beds, sponge bottoms); 4) represents useful system test whether deep corridor connects Caribbean Sea Southwest Atlantic...
Abstract The present work characterizes the time‐space scales of variability and forcing dependencies a unique 26 year record daily to hourly shoreline data from steep beach at Duck, North Carolina. Shoreline positions over 1500 m alongshore span were estimated using new algorithm called ASLIM based on fitting band high light intensity in time exposure images local Gaussian fit, with subsequent Kalman filter reduce noise uncertainty. Our findings revealed that change long times dominates...
Microplastics (MPs) are polymeric particles, mainly fossil-based, widely found in marine ecosystems, linked to environmental and public health impacts due their persistence ability carry pollutants. In São Paulo’s northern coast, geomorphological factors anthropogenic activities intensify the deposition of these Through multivariate techniques, this study aims investigate role morphometrical parameters as independent variables quantifying distribution MPs on region’s sandy beaches. Using...
Climate change is predicted to lead more extreme weather events, including changes storm frequency, intensity and location. Yet the ecological responses storms are incompletely understood for sandy shorelines, globe’s longest land-ocean interface. Here we document how of different magnitude impacted invertebrate assemblages on a tidal flat in Brazil. We specifically tested relationships between wave energy spatial heterogeneity, both habitat properties (habitat heterogeneity) fauna...
Based on the wave climate for southern Brazilian coast, refraction has been modelled in order to obtain refracted heights and directions along Santa Catarina providing needed information potential longshore drift estimates. According its coastline orientation, different sectors of coast present varying patterns. Estimates have made yearly-averaged as well each season, showing thereby patterns year. results intensities shoreline outline plan, it possible identify a strongly drift-dominated...
The hydrodynamics, morphology and sedimentology of the Taperaçu estuary were investigated. This is one several estuaries located within largest mangrove fringe in world, bordering Amazon region, subject to a macrotidal regime regionally atypical negligible fresh water supply. results reveal widespread sand banks that occupy central portion estuarine cross-section. Well-sorted very fine sandy sediments marine origin prevail. Shorter flood phases, with substantially higher current velocities,...
Abstract Large parts of tropical coastlines are influenced by the presence reefs that shape its coastline. Wave attenuation crossing as they approach coast results in accretionary coastal features developed shadow zones. With aim assessing level wave exposure coastline under different sea‐level rise scenarios, numerical modeling experiments have been designed considering a segment approximately 450 km northeast Brazil. Results show distribution power along area interest, with higher values...
The Great Amazon Reef (GARS) is an extensive mesophotic reef ecosystem between Brazil and the Caribbean. Despite being considered as one of most important ecosystems South Atlantic, recent criticism on existence a living in River mouth was raised by some scientists politicians. region coveted for large-scale projects oil gas exploration. Here, we add to increasing knowledge about GARS exploring evolutionary aspects using primary secondary information radiocarbon dating from carbonate...
This study focuses on the deposition of microplastics (MPs) urban beaches along central São Paulo coastline, utilizing advanced methodologies such as remote sensing, GNSS altimetric surveys, µ-Raman spectroscopy, and machine learning (ML) models. MP concentrations ranged from 6 to 35 MPs/m2, with highest densities observed near Port Santos, attributed industrial port activities. The predominant types identified were foams (48.7%), fragments (27.7%), pellets (23.2%), while fibers rare (0.4%)....
In contrast to traditional beach profiling methods like topographic surveys and GNSS, which pose significant challenges in terms of cost time, this research underscores the efficiency, cost-effectiveness, simplicity terrestrial photogrammetry employing Structure from Motion-Multi View Stereo (SfM-MVS) method. Notably, approach enables utilization commonplace devices such as smartphones for data capture. The methodology integrates a 12-megapixel camera image acquisition, processed through...
