UAV/UGV System for meso-macro pollutants identification in the beach environment

Suites of heavy minerals of an Argentine continental shelf sector and San Matías Gulf were studied. The preponderance of the mafic suite was characterized by the abundance of clinopiroxenes (green augites) and ortopiroxenes (hyperstenes). In scarce proportion green hornblende, brown hornblende, lamprobolite and olivine are present. The suite derived from metamorphic rocks is always in percentages lower than 10% and is represented by epidote and garnet. The suite derived from metamorphic-granitic complex appears in form of traces, integrated by zircon, tourmaline, sillimanite and andalousite. Based on heavy minerals suites it was established that the sands correspond to a volcaniclastic paragenesis. They would come from active margins related to volcanic arches. The origin of the sediment would be related to the Tertiary volcanism of the “Andes”. The sediment resting area corresponds to a passive margin. The compositional differences between the continental shelf (platform) and continental sands respond to the proximity to different sources of contribution. The different etching grain surface that heavy minerals present could be attributed to several causes, among them intrastratal solution and action of sorting and mechanical abrasion in beach environment bring out.

Abstract The complexity of human-environment interactions in coastal areas represent management challenges, especially in the beach environment, important for its ecosystem services and contribution to human well-being. To overcome these challenges, ecosystem-based management proposes a more holistic and integrated approach, with a great contribution from scientific knowledge. We present here a review of Brazilian scientific production related to beach management, focusing on the Macrometrópole Paulista. The review showed that research on beach management is in an embryonic stage, being focused on biophysical information and without presenting indications for the application of the knowledge generated in decision-making processes. We conclude that it is imperative to invest in studies with an interdisciplinary, integrated and applied approach in order to promote the ecosystem approach. This is a worldwide challenge, and has been tackled by international initiatives such as the promotion of the United Nations Decade of Ocean Science for Sustainable Development.

Biohydrogen produced from thermophilic hydrogenases is an ideal and clean energy sources. As the biggest tectonic area in the world, Indonesia is potential for thermophile isolation. The aims of this study were to analyze the bacterial diversity of a microbial mat from hot spring at Wartawan beach, Lampung and to analyze the potency of microbial mat for hydrogenases, using clone library method. The diversity of 16S rRNA showed that the microbial mat sample contained 9 phyla of bacteria, and dominated by Cyanobacteria and Proteobacteria. These phyla indicate that the bacterial community of the microbial mat consisted of phototrophic and heterotrophic groups. In addition, a microbial mat of Wartawan beach environment might be influenced by marine environment and hydrothermal vent which was indicated by detection of both associated bacteria. The diversity of hydrogenase genes using NiFe hydrogenase (NiFe) and FeFe hydrogenase (FeFe) genes showed that Cyanobacteria was specifically related to NiFe, while Firmicutes was associated with FeFe. Proteobacteria and Bacteroidetes, however, were detected for both genes. The detected hydrogenase genes indicate that the microbial mat from hot spring at Wartawan beach is a promising source for hydrogenases isolation and further applications for biohydrogen production as a renewable energy.
