“…Os EUA, Brasil, Reino Unido, França e a Itália são os países que mais investem em pesquisas científicas subaquáticas. Abrangem estudos relacionados à ambientes marinhos estuarinos e apresentam resultados que envolvem áreas tais como biologia, oceanografia, geologia e outras (Lorance & Trenkel, 2006, Linley et al, 2013, Cánovas-Molinaet al, 2016, Carminatto et al, 2020, Hartill al., 2020, Johansen et al, 2020. Todos esses ambientes são constantemente afetados pelo aumento da influência antrópica, principalmente no ambiente marítimo e estuarino com a exploração dos recursos naturais (Hughes et al, 2010, Manoukian et al, 2011.…”

“…O investimento nesta tecnologia pode vir através de órgãos governamentais (Chadwick Jr et al, 2019, Carminatto et al, 2020 ou privados (Vásquez et al, 2015, Aristizábal et al, 2016 sendo o ROV adquirido no mercado comercial internacional (Pereira-Filho et al, 2011, Carminatto et al, 2020 ou até mesmo sendo desenvolvido para fins específicos e dedicados (Wahab et al, 2020, Zhou & Zhao, 2020. Tal investimento pode trazer benefícios não somente para as entidades e colaboradores diretamente envolvidos como pode favorecer a sociedade como um todo (NUTECMAR, 2020).…”

Veículos subaquáticos operados remotamente (ROVs) fazem parte de um grupo de tecnologias que vem sendo cada vez mais utilizados como ferramenta em pesquisas científicas. As aplicações para esses veículos são vastas e o trabalho tem por objetivo apresentar análises de âmbito socioeconômico e ambiental trazendo um panorama mundial sobre as pesquisas científicas que incluem os ROVs. Foi criada uma matriz de dados com pesquisa literária sendo incluídos 78 documentos publicados. As principais informações avaliadas foram continentes e países que publicam trabalhos, parcerias realizadas entre os países, se houve ou não financiamento para a realização do projeto, qual a área de estudo e aplicação e quais as características do ROV utilizado, especialmente se ele foi desenvolvido exclusivamente para o projeto ou se houve aquisição de equipamento já existente. Notamos que os países mais desenvolvidos são os que mais investem na tecnologia, tanto em número de publicações quanto em financiamentos, fato esse que pode ser justificado pelo compromisso de as entidades governamentais fazerem aportes constantes na pesquisa científica. Em contrapartida, países em desenvolvimento como Brasil e China vem apresentando ótimos resultados e crescimento na aplicação de recursos em ciência e tecnologia. Os benefícios do investimento nesta tecnologia refletem em toda a sociedade, gerando empregos, contribuindo para a economia nacional e incentivando a pesquisa, o conhecimento e a ciência.

“…Although the quantification of human activities being exerted on the shallow marine realm globally are not fully realized, the most pronounced anthropogenic impacts are occurring in coastal and shelf environment, where the close proximity of coastal populations, infrastructure and marine resources coalesce (Harris, 2020). Increasingly, studies show that population growth and anthropogenic activities near the coast are resulting in major changes to the seafloor geomorphology and patterns of sedimentation (Paradis et al, 2017(Paradis et al, , 2018Madricardo et al, 2019), destruction of shallow marine habitats (Courrat et al, 2009;Lastras et al, 2016;Carminatto et al, 2020) and introduction of foreign materials into the shallow marine environment, including pollution, sediments and excess nutrients (Yasuhara and Yamazaki, 2005;Milliman and Farnsworth, 2013;Alomar et al, 2016;Buhl-Mortensen and Buhl-Mortensen, 2017).…”

The shallow marine environment represents a region of high biological productivity, ecological diversity, and complex oceanographic conditions, and often supports various human activities and industries. Mapping of the seafloor in shallow marine environments reveals seafloor features in detail, shedding light on a range of natural and anthropogenic processes. We present a high-resolution (2-m) multibeam dataset, combined with geologic samples that reveals a complete map of the seafloor from the land-water interface to ∼350 m water depth within Queen Charlotte Sound/Tōtaranui (QCS) and Tory Channel/Kura Te Au (TC), Marlborough Sounds, New Zealand. These data reveal that the seafloor geomorphology and distribution of natural and anthropogenic features varies spatially from the inner QCS to the Cook Strait. Tidal currents play a large role in the erosion, transport, and deposition of sediments in QCS and TC. The distribution and depth of seafloor scouring suggests that tidal flow is locally intensified by coastal geometry and bathymetric barriers, resulting in concentrated scouring where tidal flow is restricted or redirected. In addition, superimposed bedforms reflect localized variations in flow direction that have likely developed across a range of spatial and temporal scales. Evidence for extensive seafloor fluid expulsion is preserved in > 8500 pockmarks mainly located within the inner and central QCS. The size and spatial distribution of pockmarks suggest multiple fluid sources in the region. The cumulative anthropogenic footprint on the seafloor within QCS represents 6.4 km 2 (∼1.5%) of the total seafloor area and is predominantly related to maritime activities including anchor dragging (47.5%) and mooring blocks (24%). This study provides a unique example of the information that can be revealed by a comprehensive survey programme that mapped from the landwater interface to the subtidal zone. Results presented in this study form a robust basis upon which to develop improved hydrodynamic models and benthic habitat maps and to assess the full extent of anthropogenic activities in the shallow marine realm.

“…In aquatic ecosystems, anthropic activities cause changes in the structure of local vegetation, compromising the quality of water resources and the collapse of the aquatic biota (Carminatto et al 2020). The reduction of riparian vegetation cover directly affects water quality, because, among several functions, riparian vegetation acts as a natural lter that dampens the transport of pollutants through the river and regulates limnological parameters (Ribeiro Junior et al 2018).…”

The aim of this study was to (i) evaluate water quality using limnological parameters in three streams belonging to the Ivinhema River basin, (ii) investigate the composition and structure of the landscape around the locations sampled and their possible contribution to changes in water quality, (iii) investigate genotoxicity in fish in situ as environmental bioindicators, and (iv) evaluate the cytotoxic and genotoxic potential of water through bioassays in animal and plant models. A total of seven fish species were sampled in situ as bioindicators of environmental toxicogenetic damage: Astyanax fasciatus, Astyanax lacustris, Cyphocharax modestus, Moenkhausia forestii, Piabina argentea, Psellogrammus kennedyi, and Hypostomus ancistroides. Four types of nuclear and one cytoplasmic alteration were observed, with nuclear invagination being the most frequent. Animal bioassays showed five types of nuclear and one cytoplasmic alteration. In the plant bioassay, a reduction in germination and cell division was observed, indicating the cytotoxic and genotoxic effects of the water for Allium cepa cells. Thus, genotoxic alterations in fish and plant bioassays may reflect the different types of land use and cover around streams and the conversion of forest fragments into agricultural areas, mainly due to the expansion of sugarcane crops. The evaluation of the toxicogenetic status of the three streams is essential to emphasize the need to create projects to recover the native vegetation cover, which would improve the quality of the habitat and ensure the permanence of native species.
