The natural conservation of coastal lagoons is important not only for their ecological importance, but also because the valuable ecosystem services they provide human welfare and wellbeing. Coastal are shallow semi-enclosed systems that support habitats such as wetlands, mangroves, salt-marshes seagrass meadows, well a rich biodiversity. complex social-ecological with livelihoods, wellbeing to humans. This study assessed, quantified valued 32 lagoons. main findings are: (i) definitions still...
Abstract The high precipitation around Southeast Asia results in abundant freshwater outflow, which transports terrestrial dissolved and particulate material to the world's largest marginal sea, namely, South China Sea (SCS). To estimate riverine carbon flux SCS, carbonate data from 42 rivers were collected. These results, combined with literature for 13 rivers, indicate that concentrations of inorganic (DIC) are positively correlated cation exchange capacity bulk density, except Low...
The shallow-sea hydrothermal vent at Guishan Islet, located off the coast of Taiwan, serves as a remarkable natural site for studying microbial ecology in extreme environments. In April 2019, we investigated composition prokaryotic picoplankton communities, their gene expression profiles, and dissolved inorganic carbon uptake efficiency. Our results revealed that chemolithotrophs Thiomicrorhabdus spp. contributed to majority primary production waters affected by plume. metatranscriptomic...
Abstract Submarine groundwater discharge (SGD) is the submarine seepage of all fluids from coastal sediments into overlying seas. It has been well documented that SGD may contribute a great deal allochthonous nutrients to coastlines. is, however, less known how much carbon enters ocean via SGD. Nutrients (NO 3 , NO 2 NH 4 PO SiO ), alkalinity and dissolved inorganic (DIC) in were measured at 20 locations around Taiwan for first time. The total N/P/Si yields are respectively 3.28 ± 2.3 × 10...
The first data set of seasonal marine environment and euphotic zone integrated primary production (IP) variations in the Taiwan Strait was reported. measured annual IP 123±86 gC m-2 y-1 (338±235 mgC d-1), its can be described with a left-skewed normal distribution curve. average values from highest to lowest were summer (664±270 autumn (350±118 spring (202±110 d-1) winter (137±68 d-1). during nutrient-rich because it had short insolation duration, low incident photosynthetic active radiation...
In contrast to other seagrass meadows where seawater carbonate chemistry generally shows strong diel variations with higher pH but lower partial pressure of CO 2 ( p ) during the daytime and nighttime due alternation in photosynthesis respiration, inner lagoon (IL) on Dongsha Island had a unique pattern extremely high low across cycle. We suggest that this distinct could be associated enhancement total alkalinity (TA) production coupled sediment dissolution semienclosed lagoon. The...
For the first time, CH 4 concentrations in water column were measured during three cruises northern South China Sea.The abnormally high subsurface that found on continental slopes may have been released from sediments and/or originated gas hydrates.
Asia has been experiencing rapid industrialization, urbanization, and economic growth in recent decades. Taiwan was one of the 4 Asian dragons, regions that experienced industrialization exceptionally high rates between early 1960s 1990s, but at a cost to environment, thus, it heavily polluted. Estuaries are highly dynamic diverse ecosystems provide multiple ecosystem services maintain marine health benefit humankind. However, estuaries they rapidly degrading due increasing pressures...
The first investigations of seasonal N 2 O variations and water-to-air fluxes in the Tamsui River estuary its adjacent sea were carried out this study. In estuary, concentration decreased with increasing salinity. concentrations 46.8–148.5 nM autumn, 15.9–82.5 spring, 11.0–42.0 summer 13.1–120.6 winter. When salinity regressed to zero, was highest followed by winter, summer, which might be influenced DO NO 3 − as well temperature. Because mountains occlusion, wind speed not large estuary....
In this letter, the relation between thickness of SiO2 and behavior forming process has been investigated. During room temperature process, resistive switching (RS) was activated in thin (12 nm), but failed thick (23 nm). The activation failure is attributed to reformed SiOx layer due unexpected recombination excessive oxygen ions vacancies near TiN/SiO2 interface. However, RS can be presented successfully owing enhancement driving ability into TiN by employing high process.
The self-aligned formation of CoSi2 was achieved on the selective epitaxial growth (SEG) silicon layer (001)Si inside 0.1–0.6 μm oxide openings prepared by electron beam lithography. uniform, high quality SEG Si grown ultrahigh vacuum chemical vapor deposition at 560 °C with Si2H6. Self-aligned film without lateral silicide rapid thermal annealing 700 in N2 ambient. successful integration and processes promises to be a viable process technology for future deep submicron devices.
Methane (CH 4 ) is an important greenhouse gas, and its concentrations in aquatic areas are heavily influenced by anthropogenic activities, especially human-induced eutrophication, polluted river discharge wastewater treatment plant (WWTP) effluents. Although coastal estuaries contribute large amounts of global oceanic CH emissions, the relative contributions different sources have not been well determined. The Tamsui River located northern Taiwan urban flowing through populated cities thus...
Submarine groundwater discharge (SGD) is an important source of nutrients in many coastal regions, yet little information available on its carbonate chemistry and controlling factors. This study examined the processes factors hydrogeochemistry acidic property groundwaters SGD waters two isolated coral islands, Liuqiu Island (13 km off southwestern Taiwan) Dongsha (located northern South China Sea, 420 away from Island). Our results showed that total alkalinity dissolved inorganic carbon...

This study is a preliminary assessment of the greenhouse effect methane (CH4) emissions in South China Sea (SCS) on human welfare using driver-pressure-state-impact-response (DPSIR) framework and systems approach (SAF). The SCS surrounded by nations Asia-Pacific region that are currently experiencing rapid urbanization, industrialization, economic growth, one most contested maritime areas world. Climate change may aggravate regional tensions, promote natural disasters, create climate...

In this paper, we combine image segmentation techniques and face detection methods to extract the human from scenes. Firstly, skin regions are detected an ellipse fitting method is employed detect region consequently locate position. Then propose improved automatic seeded growing algorithm segment image. The initial seeds generated automatically, remaining pixels classified nearest region. After procedure, two neighboring with high similarity merged. body determined by confining semantic in...
Deposition of a boron-containing layer using B2H6 diluted with H2 on Si(001) surface has been carried out in an ultrahigh-vacuum chemical-vapor-deposition (UHV-CVD) system. The deposited layers were characterized by atomic force microscope and Auger electron spectroscopy (AES), the junction depth was determined secondary-ion-mass spectroscopy. Effective doping is accomplished before perceivable nucleation initiated. Islands are first formed substrate at small dose diborane, grains coalesce...
