“…However, there are amounts of bioavailable elements Fe, Mn, and Ba in the freshwater‐seawater transition zone. Studies showed that Fe, Mn, and Ba with high concentrations are toxic to certain marine species (e.g., Polymesoda erosa ) (Cruz et al., 2020). Therefore, the potential ecological influences of SGD‐associated Fe, Mn, and Ba from the aquifer to the ocean on marine species need to be studied in the future.…”

Trace metals in the groundwater of coastal sandy aquifers significantly influence the coastal ecosystem, yet the spatiotemporal controls of these metals remain unclear. In this paper, we comprehensively revealed the distribution patterns, key controlling factors, potential ecological risks, and fluxes to the ocean of groundwater trace metals (As, Ba, Cr, Cd, Fe, Mn, Pb, and Zn) in a coastal deep sandy aquifer. The results showed a clear zonation of trace metals in the groundwater in relation to the mixing extent between seawater and terrestrial freshwater. The freshwater zone exhibited a relatively low concentration of trace metals, whereas the freshwater‐seawater transition zone showed a substantial quantity of dissolved Fe, Mn, As, and Ba. Seawater‐groundwater interactions significantly affected the Fe, Mn, As, and Ba concentrations through redox potential and pH gradients. The tide‐driven saline water zone was vulnerable to oceanic environments and anthropogenic activities, resulting in the enrichment of trace metals such as Zn and Cd. Driven by recirculated submarine groundwater discharge (SGD), the concentrations of trace metals in the density‐driven saline circulation zone were found to be higher than those in the surrounding areas. The ecological risk index suggested that the freshwater‐seawater transition zone posted the highest ecological risks. Trace metal fluxes (i.e., Fe, Mn, and As) via SGD significantly contributed to the total input into the sea, which may have potential impacts on the coastal environments. Our study highlighted the importance of seawater‐groundwater interactions on trace element cycling in coastal sandy aquifers.This article is protected by copyright. All rights reserved.

Desa Sungai Nibung, Kubu Raya Regency, has been designated as one of the conservation areas in West Kalimantan. The coastal area of this village has potential of natural resources with a high level of diversity, including bivalves. Local community catch and sell bivalves for consumption. It is due to their high nutritional content, so that they are used by the local community as food and a source of protein. Inventory of biota is the first step to manage biological resources and support the management plan for a conservation area in this village. The study aimed to determine the diversity of bivalves in the coast of Desa Sungai Nibung, West Kalimantan. The research was conducted in December 2022. Sample collection was done using an exploratory method. Bivalves were taken, then stored in the cooling box for further identification. The result showed three bivalve species, such as Polymesoda erosa, Anadara granosa, and A. antiquata.
