A strategic review and research roadmap for offshore seaweed aquaculture—A case study from southern Australia

Reviews in Aquaculture, Journal Year: 2023, Volume and Issue: 15(4), P. 1467 - 1479

Published: Jan. 22, 2023

Abstract Global seaweed aquaculture production has more than tripled since 2002 and is dominated by Asian countries with farming operations that typically occur in relatively wave‐protected, nearshore areas. To meet future demand, must move to “non‐traditional” regions into less contested waters offshore. However, the technological complexities uncertainties performance of cultivated high‐energy offshore environments are substantial be overcome. Here, we identify knowledge gaps suggest a research roadmap inform advancement commercial industry using southern Australian species as case studies: (1) Durvillaea spp. (order Fucales); (2) four kelps Laminariales); (3) rhodophyte Asparagopsis . These groups lie along spectrum viability readiness for aquaculture, key cultivation technology suitability conditions. Cultivation restricted low level biological technical understanding, but there high market potential readiness. For laminarian kelps, conditions already occurring elsewhere, which make them most likely candidate medium term. least suited conditions, general knowledge, its land‐based systems or sheltered waters.

Using Robotics to Achieve Ocean Sustainability During the Exploration Phase of Deep Seabed Mining

Marine Technology Society Journal, Journal Year: 2023, Volume and Issue: 57(1), P. 130 - 150

Published: Feb. 27, 2023

Abstract Oceans have been a source of food and resources for life on Earth even before the advent civilization. In recent years, reliance oceans has increased due to an increasing population land, which resulted in unabated unsustainable ocean exploitation. While resilient so far allowed numerous misadventures humanity, they reached tipping point their resilience extensive use means. One such area exploitation is “deep seabed mining,” studies shown expected impact environment be catastrophic. It that resulting can substantially reduced by avoiding direct interaction humans with environment. This understanding led development technologies field robotics autonomous vehicles.This technical note thus assesses current future underwater vehicles achieve sustainability during exploration phase deep mining.

Farms and forests: evaluating the biodiversity benefits of kelp aquaculture

Journal of Applied Phycology, Journal Year: 2022, Volume and Issue: 34(6), P. 3059 - 3067

Published: Sept. 1, 2022

Abstract The biodiversity benefits of kelp aquaculture and afforestation are increasingly acclaimed as the industry continues to grow develop globally, however, whether farmed can provide this ecosystem service remains unclear. Using peer-reviewed literature, we evaluated farms benefits, identified only 23 studies that discussed effects on biodiversity, half which were broad reviews assessed concept ‘biodiversity’ peripherally (e.g. did not focus specific responses or taxa). There is also a general lack experimental research topic. Based evidence, it seems create habitat via changes local environment, particularly through provision structure changed nutrient cycling.

90-m/660-Mbps Underwater Wireless Optical Communication Enabled by Interleaved Single-Carrier FDM Scheme Combined With Sparse Weight-Initiated DNN Equalizer

Journal of Lightwave Technology, Journal Year: 2023, Volume and Issue: 41(16), P. 5310 - 5320

Published: March 27, 2023

In this paper, we first utilize the interleaved single-carrier frequency division multiplexing (I-SC-FDM) scheme with a novel sparse weight-initiated deep neural network (SWI-DNN) equalizer for underwater optical communication (UWOC) systems. addition to superior characteristics of I-SC-FDM over original OFDM and localized SC-FDM (L-SC-FDM), such as lower peak-to-average power ratio (PAPR) computational complexity, implementation special (SWI) structure can significantly reduce necessary training epochs up 10.3%, which enables proposed SWI-DNN outperform traditional random DNN equalizer. Besides, further pruning operation dramatically enhance final sparsity 96.88% at expense an inappreciable performance penalty, thereby effectively saving occupied computing resources. Following this, data rate 660 Mbps 90-m transmission be achieved in standard 50-m swimming pool, relatively low received −31.12 dBm (at BER 3.8 × 10 ⁻³ ). Such is 17.9% higher than that obtained common hybrid time-frequency domain (TFD) Moreover, complexity after only 11.83% TFD still support 625-Mbps transmission. This time employ combined long-distance high-speed UWOC transmission, it highly beneficial cost-sensitive power-sensitive systems future deployment.
