The purpose of this research is to model the condition seawater quality based on Government Regulation No. 22/2021 about «Implementation Protection and Environmental Management», results which can later be used as a basis for reference concept environmental conservation. was conducted at MV Boelongan Nederland shipwreck site, focusing measurements including physical, chemical, pollutant parameters. Sampling performed various locations near nearby estuaries using purposive sampling. Parameters such pH, temperature, turbidity, dissolved oxygen (DO), biological demand (BOD), salinity, concentrations pollutants like phenol, polyaromatic hydrocarbons (PAH), pesticides were measured analyzed geographic information system (GIS) tools. Data analysis revealed that despite some variations, parameters generally met regulatory standards, supporting marine life tourism activities. However, localized pollution observed, particularly estuary areas, emphasizing need targeted conservation efforts. indicate estuarine areas experience light due land-based runoff, could affect long-term sustainability site. overall location remains favorablefor findings suggest zoning beneficial managing underwater heritage sites, thereby both preservation economic development region.

A Physical Perspective of Recurrent Water Quality Degradation: A Case Study in the Jiangsu Coastal Waters, China

Journal of Geophysical Research Oceans, Journal Year: 2023, Volume and Issue: 128(8)

Published: July 28, 2023

Abstract Estuarine‐coastal systems receive pollutants from various sources at an alarming rate. Some are extremely susceptible to terrestrial input, as a relatively small amount of pollutant loading induces lasting water quality degradation. The Jiangsu coastal waters (JCWs), located in the southwestern Yellow Sea, such areas that lack large river discharge but suffer recurrent eutrophication recently. We hypothesize low flushing efficiency JCWs largely accounted for susceptibility pollution. To test it, transit time (TT) and rates were estimated under scenarios using validated three‐dimensional hydrodynamic model. Results show TT many inshore northern radial sand ridges is >240 days, which consistent with observed frequently eutrophic areas. better flushed thus less summer, consequence stronger tidal residual circulation. baroclinic pressure gradient, modulated by formation destruction thermal stratification offshore waters, poses dominant control on seasonal variations circulation rates, while wind effects secondary. River‐borne Yangtze local rivers shown primarily affect regions south north 32.5°N, respectively. Our study interprets vulnerability enrichment physical perspective finds be good indicator eutrophication, providing references environmental managers global estuarine‐coastal

Time-decay patterns and irregular disturbance: contrasting roles of abundant and rare microbial communities in dynamic coastal seawater

Applied and Environmental Microbiology, Journal Year: 2024, Volume and Issue: 91(1)

Published: Dec. 9, 2024

Microbial communities in coastal seas experience strong environmental disturbances, yet their response patterns, especially regarding differently abundant subcommunities, remain poorly understood. Here, through 16S rRNA gene amplicon sequencing, we investigated the diversity, time-decay pattern, and assembly process of abundant, conditionally rare taxa (CRT) microbial subcommunities temperate waters over 60 consecutive weeks. The (50.9%) CRT (46.1%) each comprised approximately half planktonic community, while contributed to extremely high species diversity. Distinct temporal heterogeneity was observed among three fractions associated with taxonomic level. subcommunity exhibited patterns at all levels, for CRT, pattern found only finer levels. In contrast, variations community loosely followed a rhythm were largely confined within specific range, likely raised from turnovers closely related taxa. Determinism dominated fraction, one more controlled by stochasticity that may be pulse terrigenous inputs anthropogenic disturbances. narrow niche widths represented stable repository offer episodic specialists, broader considered generalists fluctuating environments.

This expands current understanding revealing variation different abundances.
