Abstract Nine cruises were conducted on a seasonal basis from 2013 to 2015 investigate the spatial distribution and variability of δ 13 C 15 N in particulate organic matter (POM), its response flooding Pearl River Estuary (PRE), south China. Our study reveals highly variable isotope ratios between seasons this subtropical estuary, following climatic hydrological cycles. Wet had more isotopically depleted values, indicating dominance terrestrial freshwater algae POM, whereas contribution...
Abstract Nitrate (NO 3 − ) concentrations and the isotopic composition (δ 15 N δ 18 O) of water samples from Pearl River Estuary (PRE), south China, were measured to constrain sources processing in springtime. decreased at higher salinities, dual values correlated with 1/[NO ], both which suggest mixing eutrophic freshwater oligotrophic seawater. However, O did not closely follow expected lines. At low salinities (0–3.0), some exhibited high compared those riverine end‐member, indicating...
Abstract To investigate the sources and transformation processes of bulk marine dissolved organic matter (DOM), seasonally collected water samples from Pearl River Estuary (PRE), south China, were analyzed for concentration stable isotopic ratios (δ 13 C δ 15 N) DOM. The values clearly indicated a shift carbon (DOC) terrigenous material in river to predominantly plankton lower estuary. distribution during estuarine mixing, combination with notable deviation DOC concentration, provided strong...
Microplastics (MPs) (< 5 mm) are a growing environmental problem and have garnered significant global interest by scientists policy makers. Coastal ecosystems vulnerable to MP pollution, assessing their sources, fate, transport in the environment is imperative for marine ecosystem health. Data sediment still limited, particularly Pearl River Estuary (PRE) China. Here, we assessed abundance, characteristics, risks of MPs sediments from PRE. abundance ranged 2.05 × 103 items ·kg-1 7.75 (dry...
Abundance and distribution characteristics of three picophytoplankton groups (Synechococcus, Prochlorococcus picoeukaryotes), identified by flow cytometer, two types picocyanobacteria (phycoerythrin phycocyanin-rich strains), determined epifluorescence microscope, were assessed in contrasting periods the Pearl River Estuary, South China. The average abundance picophytoplankon was 104 cells mL–1 summer observations 103 winter. Low cell density cold season probably due to high turbidity low...
Abstract Understanding the geochemical behavior of Mo isotopes in estuarine systems is essential for determining isotopic composition riverine inputs to ocean and assessing historical oxidation state Earth’s ancient oceans. However, extent mechanisms isotope fractionation during processes are not yet fully understood. This study systematically investigated seasonal spatial variations aqueous particulate δ 98 values within Pearl River Estuary (PRE). Our research found that aque. both summer...
Abstract Millennial‐scale nitrogen (N) cycling processes in marginal seas and their response to climate change have not been well understood. Here, we present high‐resolution (ca. 110 years) organic isotope (δ 15 N org ) data since the last deglaciation (16.1 ka) derived from a highly resolved sediment core northern South China Sea, aiming explore millennial‐scale this area. Unlike most bulk records δ show clear well‐defined climatic episodes during early Holocene (EH, ∼11.7 9 ka), but...
High-resolution Holocene marine sediment records are limited, which hampers our understanding of paleomonsoon evolution. Continental shelf derived mainly from terrestrial weathering products and thus often sensitive to paleoclimate variations. In this study, the grain size magnetic mineral composition a well-dated core (YJ Core) northern inner South China Sea (SCS) were analyzed provide high-resolution record evolution East Asian summer monsoon (EASM). These indicate that EASM intensity...
The object of this study was to identify the accumulation patterns Cu, Pb, Zn and Cd in different consumers living Pearl River Estuary. Concentrations metals water, sediments tissues demersal fish, crustaceans molluscs were determined. Cluster analysis principal component used evaluate these four among species. Fish species clustered as a group which characterized by low Cd. By contrast, another high However, no significant difference Pb between two groups identified. In addition,...
