Additive Manufacturing in Underwater Applications

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(4), P. 1346 - 1346

Published: Feb. 6, 2024

Additive manufacturing (AM), commonly named 3D printing, is a promising technology for many applications. It the most viable option widespread use in automated construction processes, especially harsh environments such as underwater. Some contemporary applications of this have been tested underwater environments, but there are still number problems to be solved. This study focuses on current development printing applications, including required improvements itself, well new materials. Information about involving part fabrication via AM also provided. The article based literature review that supplemented by case studies practical main findings show usage additive can bring advantages—for instance, increasing work safety, limiting environmental burden, and high efficiency. Currently, only few prototype developed. However, tool develop new, effective larger scale. materials used, require optimization.

Published: April 25, 2024

Purpose The purpose of this paper is to review cases artificial reefs built through additive manufacturing (AM) technologies and analyse their ecological goals, fabrication process, materials, structural design features implementation location determine predominant parameters, environmental impacts, advantages, limitations. Design/methodology/approach analysed 16 from both temperate tropical regions. These were categorised based on the AM process used, mortar material used (crucial for biological applications), implementation. parameters are assessed how effectively designs meet stipulated demonstrate potential in comparison conventional methods preference locations these implementations. Findings overview revealed that dominant reef occurs Mediterranean Atlantic Seas, accounting 24%. remaining Australian Sea (20%), South Asia (12%), Persian Gulf Pacific Ocean, with 8%, Indian 4% all studied. It was concluded fused filament fabrication, binder jetting extrusion represent main processes build reefs. Cementitious ceramics, polymers geopolymer formulations incorporating aggregates mineral residues, wastes pozzolan reduce promote circular economy be more beneficial marine ecosystems. evaluation ranking well materials align demonstrating five ranked high effectiveness, ten projects moderate effectiveness one case low effectiveness. Originality/value represents an innovative method restoration management. offers a rapid prototyping technique validation enables creation highly complex shapes habitat diversification while diverse range benefit species’ habitats.

eDNA Metabarcoding Reveals the Depth-Structured Variation of Coral Reef Fish

Fishes, Journal Year: 2025, Volume and Issue: 10(5), P. 209 - 209

Published: May 2, 2025

Global coral reef ecosystems face various levels of disturbance pressure. Understanding the depth-structured variation in fish communities can help us to better grasp and predict adaptive changes ecosystem under different stressors. This study applied eDNA metabarcoding technology analyze spatial distribution at depths (0 m, 5 10 15 20 30 40 50 60 m) within Xisha Islands China. The results indicated that detected a total 213 amplicon sequence variants (ASVs), including 33 species were not identified using traditional methods. Herbivorous generally dominated relative abundance across depths. Moreover, similarity among depth groups was largely absent, significant differences existed assemblages gradients, consistent with unique preferences microhabitats. Importantly, our findings revealed distinct functional fish. Large carnivorous initially increased then decreased along gradient from 0 turning point around while large herbivorous displayed opposite trend. Small small consistently declined same gradient. Additionally, Margalef index (D) Function richness (FRic) both downward trend increasing depth, Shannon–Wiener (H′), Pielou (J′), Quadratic entropy (RaoQ), Functional dispersion (FDis), evenness (FEve) decreased, peaking m. is an effective tool for evaluating biodiversity, community composition, distribution. It enhances understanding dynamics offers valuable insights conservation restoration efforts.

Environmental assessment (EA) evaluates the environmental impacts of proposed projects, plans or policies to inform decision making. While several studies have highlighted potential and opportunities digitalisation for EA, few explored practitioners' perceptions using a mixed methods approach in order discover concerns risks identified by EA novel technological approaches. In addition, this initial exploratory study examines perception benefits contributions quality effectiveness advanced digital approaches, such as introduction artificial intelligence, practice. The research process was based on focus group discussions interviews with consultants, authorities, researchers, associations NGOs.

North Atlantic deep-sea benthic biodiversity unveiled through sponge natural sampler DNA

Communications Biology, Journal Year: 2024, Volume and Issue: 7(1)

Published: Aug. 19, 2024

The deep-sea remains the biggest challenge to biodiversity exploration, and anthropogenic disturbances extend well into this realm, calling for urgent management strategies. One of most diverse, productive, vulnerable ecosystems in deep sea are sponge grounds. Currently, environmental DNA (eDNA) metabarcoding is revolutionising field monitoring, yet complex benthic remain challenging assess even with these novel technologies. Here, we evaluate effectiveness whole-community characterise metazoan diversity grounds across North Atlantic by leveraging natural eDNA sampling properties sponges themselves. We sampled 97 tissues from four species North-Atlantic biogeographic regions screened them using universal COI barcode region. recovered unprecedented levels taxonomic per unit effort, especially phyla Chordata, Cnidaria, Echinodermata Porifera, at least 406 found our study area. These assemblages identify strong spatial patterns relation both latitude depth, detect emblematic currently employed as indicators habitats. remarkable performance approach different sponges, whole animal kingdom, illustrates vast potential samplers high-resolution biomonitoring solutions highly diverse ecosystems.
