A preliminary thermohaline characterization and water mass distribution investigation were conducted to understand the region. Unlike previous studies relying on numerical modeling, remote sensing, or sporadic in situ data, this stage of the work used temperature and salinity data collected from 2018 to 2023 during 40 oceanographic cruises. These data allowed an unprecedented seasonal description of the thermohaline structure and water mass distribution in the region. The analysis revealed distinct regions on the shelf, with seasonal thermal stratification and the presence of SACW to the south of the Doce River mouth throughout the year, while homogeneity prevailed to the north. To evaluate the canyon’s influence on the observed patterns, semi-idealized numerical simulations were conducted. These simulations indicated that the canyon significantly affects SACW distribution on the ESCS, enhancing water transport onto the shelf and facilitating the intrusion of colder waters into areas adjacent to the canyon. The canyon’s orientation and dimensions were crucial to these interactions. A dimensional analysis of Rossby numbers and the canyon’s length-to-width ratio suggested that the current over the canyon tends to break geostrophic balance, generating an intense flow toward the canyon head. Although this dynamic occurs during coastal upwelling events, the opposing current directions at the edges relative to the surface flow resulted in an anticyclonic circulation pattern, observed from the shelf break depth up to 30 meters above the canyon head. The circulation intensified as the flow compressed while moving toward shallower isobaths, crossing the canyon head. These findings highlight the importance of submarine canyons in coastal dynamics and the need for models that incorporate detailed bathymetry to capture flow-bathymetry interactions, which have implications for protected area management and oceanic pattern prediction
- ItemAnálise espacial da distribuição da comunidade zooplanctônica, com ênfase nas larvas de braquiúros em dois estuários do norte do Espírito Santo(Universidade Federal do Espírito Santo, 2024-10-02) Morais, Luana Souza de; Tognella, Mônica Maria Pereira; https://orcid.org/0000-0002-1521-8251; Silva, Maurício Hostim; Belúcio, Lucinice FerreiraBrachyurans represent the most abundant group of meroplankton, exhibiting a variety of behavioral habits and playing a crucial ecological role as decomposers. Monitoring zooplankton communities is a valuable tool for detecting environmental changes and contributing to biodiversity conservation on a global scale, due to the trophic relevance of this group. Given their abundance, diversity, and short life cycle, zooplankton are considered excellent environmental bioindicators, capable of providing significant information about the health of marine ecosystems. The present study involves sampling zooplanktonic organisms through a 10-minute surface tow using a plankton net (250 µm mesh), in addition to collecting in situ abiotic data during each tow. Ecological indices of diversity, evenness, and richness were calculated, as well as the parameters: density, abundance, and frequency of occurrence by taxon. The results were statistically analyzed using the non-parametric Kruskal-Wallis tests and Spearman’s correlation to assess the significance among samples. The study of the São Mateus River Estuary revealed considerable variations in salinity and conductivity data, related to tidal patterns. Points closer to the estuary's mouth showed higher salinity levels, as expected for this type of estuary, indicating direct marine influence. In contrast, pH and temperature showed little variation. The zooplankton community, predominantly composed of Brachyura, exhibited coastal characteristics, with brachyuran larvae reaching higher diversity at specific points (M7 and F8). The analysis of ecological indices may be explained as a response to the impact of waste from the Fundão dam collapse that reached the mouth of the Doce River, affecting the zooplankton community in the northern coast, as corroborated by Principal Component Analysis coefficients. The study highlights the complexity and importance of considering multiple factors when assessing the environmental quality of the estuary.
- ItemEconomia azul integrada ao turismo no Espírito Santo: uma abordagem da oceanografia socioambiental(Universidade Federal do Espírito Santo, 2024-08-07) Costa, Ingrid Tavares; Zappes, Camilah Antunes; https://orcid.org/0000-0002-5486-6577; https://orcid.org/; http://lattes.cnpq.br/; Barroso, Gilberto Fonseca; Lira, Pablo SilvaThe Blue Economy is a concept to integrate economic development, sustainability and social inclusion in the conservation of marine and coastal resources, with emphasis on tourism as one of the main economic sectors. In this context is inserted the Socioenvironmental Oceanography (SO) to promove sustainability and integrated management of these resources. In this sense, the objective of this dissertation is to evaluate critical points, strengths and weaknesses that interfere in the Blue Economy integrated with tourism in the metropolitan region of the Espírito Santo state, southeastern Brazil, based on the perception of stakeholders. Data were obtained through 37 interviews with stakeholders from public and/or private management in the tourism sector. Semi-structured questionnaire was used, applied the participant observation methods, field diary and participatory mapping. The stakeholders’ perception about sun and beach tourism in the metropolitan region of the coast of ES reveals that is complex and interdisciplinary segment. Positive interference demonstrates the significant economic potential of the segment, as well as the need to minimize impacts and effective public policies are necessary to increase strengths and opportunities, and minimize weaknesses and threats. Furthermore, the identification of use, attractions and priority areas for the Blue Economy in the Metropolitan Region of ES highlighted the need to discuss gaps about the Ocean Decade, Agenda 2030 and its inclusion in official documents. With this, actions based on the Blue Economy perspective were proposed to strengthen sun and beach tourism.

- ItemMinerais pesados e morfodinâmica das praias da planície deltaica do Rio Doce(Universidade Federal do Espírito Santo, 2022-05-24) Castro, Lucas Bermudes de; Albino, Jacqueline; https://orcid.org/0000-0003-2890-9227; http://lattes.cnpq.br/1609264897582182; https://orcid.org/0000-0002-1992-7813; http://lattes.cnpq.br/5597242781564517; Souza, Maria Cristina de; https://orcid.org/0000-0002-8702-7550; http://lattes.cnpq.br/0361111251040214; Quaresma, Valeria da Silva; https://orcid.org/0000-0002-7470-6642; http://lattes.cnpq.br/9423011006200936In this study, the morphodynamic and sedimentary processes responsible for the distribution and selection of heavy minerals on the beaches of a wave-dominated delta are investigated. The evolution of the deltaic plain of the Doce River is associated with high volumes of river input, long-term geological fluctuations in sea level, and variations in long- and short-term oceanographic processes. The results indicate that the proximity to the river mouth and the redistribution of sediment along the coast by longitudinal currents are responsible for a gradation of the morphological parameters of the beach between the southern and northern ends of the plain, as well as in the textural parameters of the sediments. As for the assemblages of heavy minerals, the establishment of a relationship between morphodynamics and the deposition of mineral species is less evident, but conditioned by the predominant direction of the longshore drift from the mouth. Thus, the less dense and more unstable minerals, such as amphiboles, follow the direction resulting from the longitudinal current and are associated with dissipative beaches, with low slopes and composed of fine sands, to the north of the Doce River. On the other hand, the enrichment by denser and ultrastable minerals, such as monazites, zircon and opaque minerals rich in iron, were more commonly associated with beaches to the south of the mouth, with coarse sands and a sloping beach face. The analysis of the concentration of heavy minerals in different granulometric intervals allowed us to conclude that, in general, the minerals tend to follow the “law of hydraulic equivalence” proposed by Rubey (1933), given by the density and size of the grain. However, in addition to the sediment texture, the beach morphology and the wave spreading pattern, hydrodynamic processes of the beach, interfere in the selection of heavy minerals on the beach face, suggesting the occurrence of other processes acting in the distribution and selection of heavy minerals, among them, selective drag and selection by shear.
