Spatiotemporal variability, partitioning and mixing behavior of dissolved
and particulate phosphorus in a typical subtropical river-estuary-bay continuumaccounting for 75–94 % (Benitez-Nelson, 2000). Refractory P from riverine sources is primarily removed from the oceanic P cycle through burial in coastal sediments (Goll et al., 2023), while reactive P is mainly taken up by algae and then lost from t...

A deep learning-based method for marine oil spill detection and its application in UAV imagery☆
stability (Dong et al., 2022; Zhou et al., 2018; Taleghani and Tyagi, 2017; Fingas, 2016). Oil dispersion in marine environments not only leads to large-scale surface slicks, which inhibit photosynthesis and reduce dissolved oxygen levels, but also c...

Spatiotemporal variations of halogenated polycyclic aromatic
hydrocarbons in sediments of Pearl River Estuary: Occurrence, sources, and potential ecological risksHPAHs to in situ produce in the environment (Ohura et al., 2013). Due to high lipophilicity, HPAHs can be readily accumulated in organisms and amplified through the food chain (Myers et al., 2014; Wickrama- Arachchige et al., 2020). HPAHs are recogni...

Denitrification in Hangzhou Bay: The role of nutrient dynamics in a tidal and human-impacted estuarine system
1.Introduction Present in most living organisms, nitrogen is essential for the biosynthesis of nucleic acids and proteins, thereby playing a funda- mental role in cellular processes (Mikhail and Sverjensky, 2014). It is a vital nutrient for ecosystem...

Combined effects of marine heatwaves and nano-titanium dioxide
(nano-TiO:) on the physiological fitness in the mussel Mytilus coruscus1.Introduction: Modern industrial technology,s progress has boosted nanomaterial usage in various industries due to their varied sizes and unique physi- cochemical properties (Kumar et al., 2024). For example, nano-Titanium Dioxide (nano-TiO:) is wid...

Impact of coastal deoxygenation on antibiotic resistance gene profiles in size-fractionated bacterial communities
Oxygen loss disrupts marine ecosystems, threatening biodiversity and causing mass mortality of marine life. Antibiotic resistance genes (ARGs) pose a significant threat to human health by promoting the spread of resistant pathogens, making infections...

Assessing pesticide transport and export dynamics from watersheds to Laizhou Bay, China
Pesticide residues from watersheds are increasingly exported into seawater, negatively impacting marine ecosystem health. However, existing watershed and flux models for pesticides are limited and insufficient. This study developed a Pesticides Expor...

Shifts in microbial metabolism for algal-derived organic matter utilization under dynamic oxygen conditions
1.Introduction: As human activities intensify, declining ocean oxygen has resulted in widespread hypoxia in coastal and open-ocean regions. Hypoxia is typically defined as dissolved oxygen (DO) concentrations below 63 μM (2 mg/L)(Diaz and Rosenberg, ...
