Abstract:

In this study, we first use self-organising map (SOM) and medium-resolution imaging spectrometer (MERIS) full-resolution (FR) level-2 total suspended matter (TSM) product to identify spatial-distribution patterns of TSM concentration in the Pearl River estuary. Second, the spatial and temporal variation of TSM concentration in the Pearl River estuary was investigated using 9-year (2003–2011) MERIS FR level-2 TSM products. The spatial-distribution patterns of TSM concentration identified by SOM in the Pearl River estuary showed that there are high values in west and north and low values in east and south. On the basis of the analysis of the sample points randomly extracted from the Pearl River estuary, the results showed that the spatial variation of TSM in eight gates varied greatly, and the Lingdingyang Bay from Humen to offshore waters (i.e. Xitan, Zhongtan and Dongtan) presents a decreasing trend. Moreover, extreme climate events (e.g. EI Niño and La Niña) may have a great effect on spatial and temporal variation of TSM concentration in the Pearl River estuary. These results could provide a new insight for a better understanding of the dynamics of TSM concentration in the Pearl River estuary and the effect of soil- and water-conservation measures in the upstream of Pearl River.

Abstract:

The HZM(Hongkong-Zhuhai-Macao) bridge connects Hongkong, Zhuhai and Macao district, and it strctchs across the Pearl River estuary. A lot of piers and three large artifical islands would have some impact on the hydrodynamic environment in the Pear River estuary. In this paper, a 2D tidal current numerical model is introduced to simulate the hydrodynamic impact from the HZM brdige. The simulated results show that the Hydrodynamic influence is concentrated on the 5.0 km range from downstream to upstream nearby the navigation zone and the 1.0 km range of bridge site in not-navigation zone, and the tidal range reduction is limited 0.03m and the tidal prism reduction is not more than 1% in the Lingding Sea after the HZM bridge constructed. Therefore, the HZM bridge has little influence on the distribution of hydrodynamic environment in the Pearl River estuary.

Abstract:

Abstract. The niche differentiation of ammonia and nitrite oxidizers is controversial because they display disparate patterns in estuarine, coastal, and oceanic regimes. We analyzed diversity and abundance of ammonia-oxidizing archaea (AOA) and β-proteobacteria (AOB), nitrite-oxidizing bacteria (NOB), and nitrification rates to identify their niche differentiation along a salinity gradient from the Pearl River estuary to the South China Sea. AOA were generally more abundant than β-AOB; however, AOB more clearly attached to particles compared with AOA in the upper reaches of the Pearl River estuary. The NOB Nitrospira had higher abundances in the upper and middle reaches of the Pearl River estuary, while Nitrospina was dominant in the lower estuary. In addition, AOB and Nitrospira could be more active than AOA and Nitrospina since significantly positive correlations were observed between their gene abundance and the nitrification rate in the Pearl River estuary. There is a significant positive correlation between ammonia and nitrite oxidizer abundances in the hypoxic waters of the estuary, suggesting a possible coupling through metabolic interactions between them. Phylogenetic analysis further revealed that the AOA and NOB Nitrospina subgroups can be separated into different niches based on their adaptations to substrate levels. Water mass mixing is apparently crucial in regulating the distribution of nitrifiers from the estuary to open ocean. However, when eliminating water mass effect, the substrate availability and the nitrifiers' adaptations to substrate availability via their ecological strategies essentially determine their niche differentiation.

Abstract:

An investigation was conducted to characterize the trace element status of mangrove soils of Qi’ao Island in the Pearl River estuary. The results show that the spatial variation in the soil-borne trace elements in the investigated area was minor and most of the trace elements were at a level higher than those in other mangrove wetlands around the world, suggesting the mangrove soils of Qi’ao Island were heavily contaminated by trace elements transported from the Pearl River in the past two decades. Zn was closely related to Pb, Cu, Cd, and As, while some trace elements were not closely related to each other, indicating that they were derived from different sources. An integrated Nemerow pollution index of the surface soils at the 17 sampling locations ranged from 7.53 to 48.42, values which all fall within the highest pollution category. Among the 17 sampling locations, six locations had an ecological risk index (ERI) greater than 300, and 12 locations had an Ecological Risk Index (ERI) greater than 600, indicating that most of the investigated locations were at high or very high ecological risk. The findings obtained from this study have implications for understanding the terrestrial inputs of trace elements into part of the Pearl River estuary. This understanding can be used to guide the development of management strategies for controlling the discharges of trace elements from the catchment area and managing the aquatic ecosystems in the Pearl River Estuary.

Abstract:

This is a research on the change of nutrients and its structure in the Pearl River Estuary by the principal component analysis (PCA) according to the data and materials on water quality observation in the last 30 years around the Pearl River Estuary. Results showed that inorganic nitrogen (DIN) presented an obvious increase trend in the last 30 years, while phosphate and silicate presented an outstanding decrease trend in this area by the influence of human activities. The average N/P ratio increased by 1.44 times, the Si/N ratio decreased by 66.8%, the Si/P ratio decreased by 18.5%, and the structure of nutrients changed significantly. According to the results of PCA, the first two principal components (PC) were extracted. PC1 was associated with GDP, population, industrial output value and wastewater discharge, which explained 80.9% of the variance. PC2 was characterized by cultivated land area, which explained 14.6% of the variance. It indicates that the change of nutrients content and structure in the Pearl River Estuary was closely related to economic development and industrial pollution discharge, and the effect of the change of land use and land cover on the change of nutrients should not be ignored.

Abstract:

Abstract. We investigated the spatial distribution and seasonal variation of dissolved inorganic nitrogen in a large perturbed estuary, the Pearl River Estuary, based on three cruises conducted in winter (January 2005), summer (August 2005) and spring (March 2006). On-site incubation was also carried out for determining ammonium and nitrite oxidation rates (nitrification rates). We observed a year-round pattern of dramatic decrease in NH4+, increase in NO3−, but insignificant change in NO2− in the upper estuary at salinity ~0–5. However, species and concentrations of inorganic nitrogen at upper estuary significantly changed with season. In winter, with low runoff, the most upper reach of the Pearl River Estuary showed relatively low rates of ammonia oxidation (0–5.4 μmol N L−1 d−1) and nitrite oxidation (0–5.2 μmol N L−1 d−1), accompanied by extremely high concentrations of ammonia (up to >800 μmol L−1) and nitrate (up to >300 μmol L−1). In summer, the upper estuary showed higher nitrification rates (ammonia oxidation rate ~1.5–33.1 μmol N L−1 d−1, nitrite oxidation rate ~0.6–32.0 μmol N L−1 d−1) with lower concentrations of ammonia (<350 μmol L−1) and nitrate (<120 μmol L−1). The Most Probable Number test showed relatively lower nitrifier abundance in summer at most sampling stations, indicating a greater specific nitrification rate per cell in the warm season. Temperature appeared to control nitrification rates to a large degree in different seasons. Spatial variability of nitrification rates appeared to be controlled by a combination of many other factors such as nutrient concentrations, nitrifier abundance and dissolved oxygen (DO) concentrations. In addition to aerobic respiration, nitrification contributed significantly to the consumption of DO and production of free CO2 at upper estuary. Nitrification-induced consumption accounted for up to approximately one third of the total water column community DO consumption in the upper estuary during the surveyed periods, boosting environmental stress on this large estuarine ecosystem.

Abstract:

The principal aim of this thesis is to reconstruct East Asian Monsoon (EAM) variability during the mid-Holocene, developing a relatively new proxy of bulk organic carbon isotopic signature (δ13C). C/N ratios and trace elements are also employed to conduct a multi-proxy case study from the Pearl River estuary, southern China. Sources of sediments within an estuary include river-derived terrestrial/freshwater input, in situ brackish-water suspended sediment and tide-derived marine input. This study assumes the three proxies can help differentiate sources of sediments relating to monsoon-driven freshwater flux and help reconstruct monsoonal precipitation history during the mid-Holocene when the sea level was relatively stable. To achieve the aims of this thesis a range of modern samples were collected from terrestrial areas, including plants and soil samples, through to estuarine areas, including seasonal estuarine suspended organic matter (SOM) and surface sediment. Results suggest that bulk organic δ13C and C/N ratios can successfully identify sources of the organic component of the estuarine sediment, and thus can be used to infer relative changes in monsoon-driven freshwater flux to the estuary. For example, more negative δ13C values reflect a greater level of contribution of freshwater organic carbon, i.e. stronger monsoonal freshwater discharge. Results also show that a combination of selected metals, such as the terrigenous metals (Fe, Mn, Co and As), can be useful for indicating sediment sources and sedimentary environment. Analysis of an estuarine core (UV1) shows that freshwater discharge from the Pearl River catchment gradually declined from 6400 to 2000 cal. years BP, suggesting a gradual weakening of summer monsoon precipitation, responding to the weakening insolation controlled by the orbital-driven precession cycle. Superimposed on this are wet/dry intervals, ranging from centennial- to millennial- scale, driven by solar activity. Changes in ENSO and high-latitude cooling events might be responsible for dry/wet events at centennial- to decadal- scale, identified during the mid-Holocene. This study also suggests that the coupling of thermal and moist conditions of the EAM might only have become stable after 4500 cal. yr BP. A sudden shift in the geochemical signature indicates agricultural activity in the Pearl River delta intensified from 2000 cal. yr BP.

Abstract:

The Asian Summer Monsoon (ASM) is an important climate system, affecting over half of the global population. Understanding past ASM changes is therefore crucial for assessing potential impacts of future climate change in Asia. However, previous reconstructions of ASM precipitation intensity generally rely on the local-scale catchments of lake, cave and vegetation-based records. There is significant disparity between these records, possibly attributable to local microclimate responses overprinting the regional signal. This thesis reconstructs precipitation-driven river flux to the Pearl River Estuary (PRE), a major river system in China, to record monsoon variability over a more regional scale. A suite of biornarker-based ratios indicative of terrestrial organic matter (TOM) flux (the concentration ratio of terrestrial to marine n-fatty acids, n-alcohols and sterols, and the BIT Index), are analysed in contemporary grab samples and a sediment core from 6.5 ka to present. Additionally, carbon isotope (813C) values of leaf wax n-fatty acids are analysed from 6.5 ka to present to assess potential vegetation change. TOM input to the modem PRE generally decreases from river to ocean. Superimposed on this decrease, the biomarker distributions record a rapid decrease across the delta toe, indicating that organic matter (OM) burial is largely dictated by the sedimentary regime. From 6.5 ka to present, BIT indices show strong covariance with a precipitation record within the drainage basin, indicating that soil OM input to the PRE covaried with paleoprecipitation 6.5 ka to present. The other three biomarker ratios also record a general decrease in TOM. However, these ratios record some disparity at 5.5 ka, suggesting a change in vegetation OM input to the core. Leaf wax 813C values record a significant enrichment at 2 ka, consistent with a previously published bulk 813C record, suggesting an anthropogenically-driven shift to a greater C4 plant component with the onset of agriculture. 111.

Abstract:

The thesis is a study of the subsistence of the Pearl River Estuary (abbreviated as PRE) area in the southernmost Mainland China during the Neolithic (6,000-3,500 BP). Despite poor preservation of organic subsistence material in this (sub) tropical and coastal area, important Neolithic sites, artifacts and faunal remains have been unearthed in recent years. Some new methods such as isotopic analysis have been employed. To make good use of the data and make up for the geographic disadvantage in preservation, it is attempted in this thesis to summarize and interpret available archaeological material, coupled with site catchment analysis, to address the subsistence. First, the subsistence of the Early Neolithic of Lingnan is discussed, and used as a fore-scene to suggest the PRE subsistence appearing later in the Middle Neolithic. Second, ecofact, artifact and site data of the PRE (Middle/Late Neolithic) are synthesized, serving as a solid but limited factual foundation for assessing the subsistence. Finally, site catchment analysis is used to enhance or mutually verify with the empirical material, or to provide new lines of reference. Ecological data are integrated wherever possible. The conclusion is that the Neolithic subsistence of the PRE would have been generally foraging based, particularly fishing and mollusk collecting. However, farming would have been playing more and more important role, especially during the Late Phase of the Late Neolithic (4,300-3,500 BP), with probable economic and political interactions with rice farming cultures, increase of sedentism, exchange and population, and of social competition with other groups in South China. The PRE case tends to confirm to the understanding that even though farming skill was mastered, if foraging resources were rich and handy, foraging would have prevailed and farming might have been maintained to the minimum just as a supplement.

This study investigated the concentration distribution of perfluorinated compounds (PFCs) in the Pearl River estuary of China. Collects samples of seawater and core sediments at different depths to understand the transport behavior of PFCs in the environment. Seawater and core sediment samples were collected from the Pearl River estuary of China at different depths to understand the transport behavior and contribution of PFCs in the area. The results showed that the total concentration of PFCs in seawater ranged from n.d. to 15.10 ng/L, and the predominant compounds of PFCs in seawater samples were perfluorobutyl sulfonate (PFBS) is different from other regions, suggesting that the Pearl River Delta region may have specific sources of PFBS pollution. The results also showed that the total concentration range of PFCs in sediment was n.d. to 2.68 ng/g, and the major compounds of PFCs in the seawater samples were perfluorooctanoic acid (PFOA), which is similar to that of PFCs from other studies. In addition, the total concentration of PFCs in seawater and sediment samples decrease with the depth increasing, similar to global emission trends for total PFCs. Compared with other literatures, although the highest polluted area was not found in the sampling region of this study, but the concentration distribution is affected by high industrialization, urbanization, and humam activities. Total organic carbon content (TOC) was significantly negatively correlated with mean particle size (r = -0.438, p = 0.01); and TOC was significantly positively correlated with total concentration of PFCs (r = 0.323, p = 0.01). The data are consistent with other previous. The sediment samples were analyzed by principal component analysis (PCA) and hierarchical cluster analysis (HCA) to identify their compositions. The results can be divided into two clusters, the one cluster included PFOA, Perfluorooctane sulfonate (PFOS); another cluster was predominated by PFBS, Perfluorohexyl sulfonate (PFHxS) and Perfluorodecanoic acid (PFDA).

Abstract:

The hydrology of the Pearl River Estuary is controlled both by river discharge and tide, where water and sediment move through eight outlets (mouths) into the sea. Using numerical modeling, this paper examines the characteristics of tidal movement in Pearl River Estuary. Results showed an amphidromic point near Modaomen mouth, and river runoff flows down. From marine dynamics point of view, Modaomen mouth is the main channel for water and sediment transportation of Pearl River. Using the tidal energy, we discuss the change of the sediment near the several entrances during the flood and dry seasons.

Abstract:

The increase of saltwater intrusion in recent years in the Pearl River Delta, has threatened the freshwater supply in the surrounding regions, especially the cities of Zhongshan, Zhuhai, Guangzhou in Guangdong Province and Macau. A numerical modeling system using nested grids was developed to simulate the salinity distribution in the Pearl River delta, and then to investigate the salt transport process and calculate the salt flux for each outlet in the Pearl River estuary. The model forcing functions consist of tidal elevations along the open boundaries and freshwater inflows from the major tributaries in the Pearl River system. The model simulation results are in qualitative agreement with the available field data. The salt flux of the Pearl River delta during the spring tide in dry season is up to 19.5×106ton/ tidal period, while the salt flux during neap tide is only 5.1×106ton/ tidal period, 26.18% of that during the spring tide. The salt flux in Dahu and Guanchong stations are the highest among the stations of the eight outlets, indicating that Humen and Yamen are the most important entries for saltwater intrusion in the Pearl River delta. The most important reason is that the ratio of stream flow to tide flow is different for each outlet. The ratios at Humen and Yamen are the smallest among the eight outlets (<1 for each month), while the ratio at Modaomen is the biggest (>1 for each month), which leads to the lowest salt flux at Modaomen. Salinity distribution in different time periods shows that saltwater intrusion during the spring tide is much more serious than neap tide, and water in many cities during this time period will be unavailable for drinking, irrigation or for ecological purpose.
