This study investigated the effect of aeration rate and light intensity on biomass production total fatty acids (TFA) accumulation by Porphyridium purpureum. The red microalgae is also known to accumulate considerable amount arachidonic acid (ARA). In artificial seawater medium, highest yield TFA (473.44 mg/L) was obtained with 3 L/min 165 µmol/m2s, whilst ARA (115.47 achieved 110 µmol/m2s. It found that higher led more TFA/ARA production. However, could contribute accumulation, but it...
Abstract Submarine groundwater discharge (SGD) dynamically links land‐ and ocean‐derived chemical constituents, such as metals, in the coastal ocean. While many metals are sediment‐bound, changing environmental conditions, particularly along coast, may lead to increased release of their dissolved more bioavailable form. Here, we review metal behavior, speciation, drivers mobilization environment under anthropogenic influence. We also model global contamination risk ocean via SGD considering...
Abstract As a significant source of nutrients and other components into the coastal ocean, submarine groundwater discharge (SGD) is combination multiple spatial‐temporal scale processes, including fresh terrestrial (FSGD), recirculating seawater (RSGD), porewater exchange (PEX). Quantifying different types SGD extremely important for understanding biogeochemical cycles various materials. The green tide bloom in southern Yellow Sea (China) has attracted increasing attention during past...
We present the synthesis of two-dimensional Au-PdAg hybrid electrocatalysts with two distinct morphologies through site-specific deposition in seeded growth. The co-reduction Pd and Ag precursors presence of...
The production of copious quantities waste palm oil mill effluent (POME) is an unavoidable consequence industries, and requires effective treatment before discharge into the environment. Microalgae possess a significant nutrient bio‐sorption capacity in addition to high photosynthetic carbon bio‐sequestration rates, hence can be exploited for sustainable POME operations. Bioprocess research on use microalgal cells remove specific chemical species from limited. This work investigated...
Abstract Ferromanganese nodules (Fe‐Mn nodules) are considered as potential sources of in‐demand metals (such manganese, cobalt, nickel, copper, and rare‐earth elements) that used in high‐technology industries. The resource Mn the world ocean remains uncertain due to technological financial challenges. Here we propose an effective tracer: natural radioactive radon isotope ( 222 Rn) assess abundance Fe‐Mn on sea floor. Significant linear relationships were observed between benthic excess Rn...
Abstract Foraminiferal taphocoenose characteristics, notably allochthonous tests in surface sediment samples from the Yangtze River Estuary and adjacent areas East China Sea, were examined during (July 2016) after typhoon Nepartak (February 2017) crossed this region. A comparison of transport indices five sample stations reveals that significantly strengthened transport, although predominate direction (TWC north branch) occurs all year. Moreover, findings a comprehensive impact currents,...
Abstract Submarine groundwater discharge (SGD) can have a profound influence on marine environments and elemental biogeochemical cycles in coastal waters. We explored the feasibility of using Ba/Ca ratios benthic foraminiferal shells as proxy SGD. Dissolved barium (DBa) displayed enrichment behavior bottom waters indicating that SGD is major DBa source Changjiang (Yangtze) Estuary. Foraminifera lived with elevated 222 Rn activities (high SGD) showed larger range than those under low water...
Abstract An appropriate proxy could help to better understand dissolved oxygen variations in the past, helping predict potential outcomes of future environmental changes. In Changjiang Estuary (China), foraminifer Cribrononion subincertum ( C. ) shows a distinct population maximum topmost sediment, an indication epifaunal species. Therefore, geochemical composition tests record changes region’s bottom water chemistry. Our results showed that Mn/Ca ratios living (Rose‐Bengal stained) analyzed...
Abstract The sediment mixed layer (SML) in the deep ocean is an important interface with a rich diversity of benthic organisms. With increasing mineral exploration, and eventual mining, effect mixing on ecosystems has raised considerable concern. We evaluate distribution patterns driving factors SML depth nodule fields using naturally occurring 210 Pb– 226 Ra isotopes. Results show that average increased Mn‐nodule since end last century. processes are associated significant desorption from...
