“…0.17-4.58 wt% Fe;Morisson et al, 2010;Magallanes-Ordóñez et al, 2015) and coastal sediments (i.e. 0.2-7 wt% Fe; Anbuselvan et al, 2018;Koukina et al, 2017) under tropical climate, this correlation suggests that TOC might be a limiting factor for Fe(III) microbial reduction (and in turn, pyritization) in the studied Fe-rich lagoon sediments of New Caledonia. This limiting character of the TOC available to fuel microbial reduction of Fe(III) associated with goethite and/or clay minerals has already been proposed to explain the low formation of pyrite in subsurface redox transition zone or sediments (Benzine et al, 2013;Sabadini-Santos et al, 2014;Wu et al, 2017).…”

Pyrite contribution to Ni and Fe speciation is low and restricted to the sediments close to the shore Clay minerals are the major host for Fe and Ni across the shore-to-reef gradient Fe-rich smectite, glauconite, chrysotile and greenalite/berthierine are the major Fe and Ni-bearing clay minerals identified Greenalite/berthierine is the most Ni-rich clay mineral identified and it is considered to have formed in-situ upon early diagenesis Green clay authigenesis might represent a major process for trace metals cycling in shallow lagoon sedimentary settings *Highlights (for review : 3 to 5 bullet points (maximum 85 characters including spaces per bullet point) Lagoon sediments, trace metals, speciation, green clays, TEM, XAS.

Dataset on the abundance, enrichment and partitioning of chemical elements between the filtered, particulate and sedimentary phases in the Cai River estuary (South China Sea)

This data article refers to the paper entitled “Multi-element signatures in solid and solution phases in a tropical mixing zone: A case study in the Cai River estuary, Vietnam” (Koukina et al., 2021), which considers the fate of major, trace, and rare-earth elements transported through the estuarine geochemical filter of the typical tropical estuary. The present work contributes to the local geochemical baselines as a background for long-term monitoring of potential hazardous elements. Therefore, the dataset covers the abundance, enrichment, and partitioning parameters of 53 chemical elements in the water, suspended particulate matter, and bottom sediment samples collected in the Cai River estuary and the adjacent part of the Nha Trang Bay (South China Sea) between July and August 2013. The total filtered, particulate, and sedimentary elements were determined by atomic emission and inductively coupled plasma mass spectrometry (ICP-AES; ICP-MS). The environmental indices (the enrichment factor and geoaccumulation index) and partition coefficients were calculated from the total element contents. The data provided is essential for the comprehensive environmental assessment of the anthropogenic impact on the coastal ecosystem as well as for the evaluation and modelling of element fractionation and mobility at the estuarine gradients.

“…riverine inputs; Sharley et al, 2016) and local anthropogenic activities via point and diffuse sources (Jeffries et al, 2016, Eggleton andThomas, 2004). Many of these contaminants accumulate in estuarine sediment (through binding with particulate matter and settling) and become part of the water-sediment system (Koukina et al, 2016). At high concentrations, these contaminants can have toxic or enriching effects on biota and interfere with important ecosystem functions (e.g.…”

This Special Issue of Estuarine, Coastal and Shelf Science presents contributions from ECSA 55; an international symposium organised by the Estuarine and Coastal Sciences Association (ECSA) and Elsevier on the broad theme of estuaries and coastal seas in times of intense change. The objectives of the SI are to synthesise, hypothesise and illustrate the impacts of global change on estuaries and coastal seas through learning lessons from the past, discussing the current and forecasting for the of combining cross-disciplinary palaeo, contemporary and future modelling studies and; (4) the importance of shifting baselines on ecosystem functioning and the future provision of ecosystem services.
