A global compilation of diatom silica oxygen isotope records from lake sediment – trends and implications for climate reconstruction (2024)
Journal Article

Oxygen isotopes in biogenic silica (δ18OBSi) from lake sediments allow for quantitative reconstruction of past hydroclimate and proxy-model comparison in terrestrial environments. The signals of individual records have been attributed to different fa...

Identifying the controls on nitrate and metabolic state within the Red River delta (Vietnam) with the use of stable isotopes (2023)
Journal Article

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...

Indian Ocean glacial deoxygenation and respired carbon accumulation during mid-late Quaternary ice ages (2023)
Journal Article

Reconstructions of ocean oxygenation are critical for understanding the role of respired carbon storage in regulating atmospheric CO2. Independent sediment redox proxies are essential to assess such reconstructions. Here, we present a long magnetofos...

Ecosystem deterioration in the middle Yangtze floodplain lakes over the last two centuries: Evidence from sedimentary pigments (2023)
Journal Article

Water quality of floodplain lakes in the Yangtze region which supports ca. 450 million people is being severely compromised by nutrient pollution, climate change and dam installation resulting from intensive socio-economic development. However, due t... Read More about Ecosystem deterioration in the middle Yangtze floodplain lakes over the last two centuries: Evidence from sedimentary pigments.

Eutrophication has a greater influence on floodplain lake carbon cycling than dam installation across the middle Yangtze region (2022)
Journal Article

Carbon cycling in shallow floodplain lakes is complex due to variability in delivery of flood-derived allochthonous organic matter (OM). Human activities have potential to significantly modify the carbon balance of lakes by damming which restricts ex...

Urbanization and seasonality strengthens the CO 2 capacity of the Red River Delta, Vietnam (2022)
Journal Article

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

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...

Reconstruction of short-term storm surge-driven increases in shallow coastal lake salinity using ostracod shell chemistry (2022)
Journal Article

Climate change threatens the current protection provided by coastal defences in low-lying mid-latitude regions and increases the risk to coastal lakes from future frequent and intense storms. Quantifying and understanding the impacts of past storm su...

Stalagmite evidence for Early Holocene multidecadal hydroclimate variability in Ethiopia (2022)
Journal Article

A multiproxy oxygen and carbon isotope (δ13C and δ18O), growth rate, and trace element stalagmite paleoenvironmental record is presented for the Early Holocene from Ethiopia. The annually laminated stalagmite grew from 10.6 to 10.4 ka and from 9.7 to... Read More about Stalagmite evidence for Early Holocene multidecadal hydroclimate variability in Ethiopia.

Nutrient availability in the North Pacific region not primarily driven by climate through the Quaternary (2022)
Journal Article

The subarctic North Pacific Ocean is a relatively understudied region in terms of palaeoclimate, limiting our understanding of how the region has both driven and responded to palaeoenvironmental events. Today, the subarctic North Pacific Ocean is mar... Read More about Nutrient availability in the North Pacific region not primarily driven by climate through the Quaternary.

Climate and human exploitation have regulated Atlantic salmon populations in the River Spey, Scotland, over the last 2000 years (2022)
Journal Article

Historical salmon catch records suggest that climatic variability, and more recently human exploitation, control patterns of abundance in Atlantic salmon populations. We present the first long-term (2000-year) reconstruction of Atlantic Salmon popula...

Micromilling vs hand drilling in stable isotope analyses of incremental carbonates: The potential for δ 13C contamination by embedding resin (2022)
Journal Article

Rationale: Embedding resins are commonly used to facilitate high-resolution sampling for stable isotope analysis but anomalous δ13C values have been observed in some cases. Here we compare the results of microsampling strategies for hand-drilled vers...
