The coal pillar dam of underground reservoirs and residual in goaves have a direct impact on the quality mine water. In this paper, an reservoir goaf water Daliuta are used as research objects. adsorption mechanism with respect to NO3− was analyzed by carrying out experiments. composition variation organic matter at different times were simulated using three-dimensional fluorescence spectrum analysis. influence microorganisms change contents explored. Moreover, changes body clarified. results showed that concentration first decreased then increased, showing downward trend whole. led decrease its concentration, which conformed pseudo-second-order kinetic model Freundlich isothermal model, indicating process is mainly carried via chemical multi-layer adsorption. increase caused hydrolysis tryptophan other protein-like substances into nitrate under action microorganisms.

Abstract Hadal trenches have recently been recognized as hotspots for organic carbon burial and degradation in the deep sea owing to its distinctive “funnel‐shaped” topography frequent tectonic activity. In this study, we analyzed dissolved (DOC) concentration, optical properties, molecular compositions of water‐extractable matter (WEOM) sediment samples collected along two transects spanning diverse marine environments New Britain Trench (NBT) area. A significant positive correlation between DOC concentrations total (TOC) contents sediments emphasizes crucial role (OM) supply production hadal environment. addition, parameters (e.g., fluorescence index, a 350 /DOC) suggest remarkable influences terrestrial OM on composition (DOM) NBT sediments. Indeed, correlations stable isotopes sedimentary TOC (δ 13 C) related (SUVA 254 , /DOC, S R humic‐like) indicate that microbial has an important impact DOM. Moreover, analysis DOM showed increased aromaticity double bond equivalents equivalent western landward core axis cores, also suggesting enhanced OM. The input into led aromatic, refractory, high weight Our findings implications understanding fate ocean.

Abstract Appendicularians are recognized as one of the most abundant mesozooplankton groups in numerous pelagic environments and they play a crucial role marine ecosystems bridge gap between primary producers higher trophic levels food webs. Zooplankton samples were collected during three spring oceanographic surveys conducted 2014, 2015, 2016, coastal zone (Staten Island) oceanic (Namuncurá-Banco Burdwood Marine Protected Area). Our study focuses on comparative analysis species composition, density, biomass, maturity stages appendicularia these regions, which marked by distinct physical biological attributes. Two appendicularians found area, Oikopleura fusiformis Fritillaria borealis, former being dominant. Their distribution was different because F. borealis mainly concentrated while O. consistently recorded both zones. Chlorophyll-a concentrations to be than zone. These accompanied densities that area. The surface current velocity seems reflect total phytoplankton biomass On other hand, temperature for protected area lower could related larger sizes Baseline data areas surrounding is essential contribute stakeholders advise future changes translate into regional global processes.
