Smith, A. C., Leng, M. J., McGowan, S., Panizzo, V. N., Ngo, T. T. T., Luu, T. N. M., …Trinh, A. D. (2024). Identifying the controls on nitrate and metabolic state within the Red River delta (Vietnam) with the use of stable isotopes. Journal of Hydrology, 628, Article 130467. https://doi.org/10.1016/j.jhydrol.2023.130467

In many places around the world, anthropogenic activities have resulted in nitrate (NO3−) pollution and changes in the metabolic state of aquatic ecosystems. Here we combined stable isotope and physico-chemical monitoring to assess the sources of NO3...

Urbanization and seasonality strengthens the CO 2 capacity of the Red River Delta, Vietnam (2022)
Journal Article
Salgado, J., Duc, T. A., Nga, D. T., Panizzo, V. N., Bass, A. M., Zheng, Y., …McGowan, S. (2022). Urbanization and seasonality strengthens the CO 2 capacity of the Red River Delta, Vietnam. Environmental Research Letters, 17(10), Article 104052. https://doi.org/10.1088/1748-9326/ac9705

Tropical rivers are dynamic CO2 sources. Regional patterns in the partial pressure of CO2 (pCO2) and relationships with other a/biotic factors in densely populated and rapidly developing river delta regions of Southeast Asia are still poorly constrai...

In flux: Annual transport and deposition of suspended heavy metals and trace elements in the urbanised, tropical Red River Delta, Vietnam (2022)
Journal Article
Roberts, L. R., Do, N. T., Panizzo, V. N., Taylor, S., Watts, M., Hamilton, E., …Salgado, J. (2022). In flux: Annual transport and deposition of suspended heavy metals and trace elements in the urbanised, tropical Red River Delta, Vietnam. Water Research, 224, Article 119053. https://doi.org/10.1016/j.watres.2022.119053

Due to the depositional environment, river deltas are said to act as filters and sinks for pollutants. However, many deltas are also densely populated and rapidly urbanizing, creating new and increased sources of pollutants. These sources pose the ri...

Using stable isotopes to estimate young water fractions in a heavily regulated, tropical lowland river basin (2020)
Journal Article
Trinh, A. D., Do, T. N., Panizzo, V. N., McGowan, S., & Leng, M. J. (2020). Using stable isotopes to estimate young water fractions in a heavily regulated, tropical lowland river basin. Hydrological Processes, 34(22), 4239-4250. https://doi.org/10.1002/hyp.13878

© 2020 John Wiley & Sons Ltd The young water fraction of streamflow (Fyw), an important hydrological variable, has been calculated for the first time, for a monsoon-fed coastal catchment in northern Vietnam. Oxygen stable isotopes (δ18O) from six r... Read More about Using stable isotopes to estimate young water fractions in a heavily regulated, tropical lowland river basin.

Influence of the ratio of planktonic to benthic diatoms on lacustrine organic matter ? 13 C from Erlongwan maar lake, northeast China (2012)
Journal Article
Wang, L., Mackay, A. W., Leng, M. J., Rioual, P., Panizzo, V. N., Lu, H., …Kendrick, C. P. (2013). Influence of the ratio of planktonic to benthic diatoms on lacustrine organic matter δ 13 C from Erlongwan maar lake, northeast China. Organic Geochemistry, 54, 62-68. https://doi.org/10.1016/j.orggeochem.2012.09.010

Carbon isotope ratio (δ 13 C org ) values of organic matter in lake sediments are commonly used to reconstruct environmental change, but the factors which influence change are varied and complex. Here we report δ 13 C values for sediments from Erlong...

Geochemical analyses (x-ray fluorescence, δ13C and C/N ratios) were used to reconstruct early Holocene environments (between 10685 and 7260 cal. yr BP) at a small lake near Holebudalen, southern Norway. Results show a period of increasing stability,...

Journal Article
Mackay, A. W., Karabanov, E., Leng, M. J., Sloane, H. J., Morley, D. W., Panizzo, V. N., …Williams, D. (2008).

Journal of Quaternary Science, 23(4), 365-374. https://doi.org/10.1002/jqs.1174

In this paper we reconstruct hydrological variability in Lake Baikal during Marine Isotope Stage 11 (MIS 11) (427-362 ka BP) from oxygen isotope analysis of diatom silica. Highest δ18Odiatom values are found during MIS 11.3, highlighting the dominanc...
