Polycyclic aromatic hydrocarbons are present in all
environmental matrices. Polycyclic aromatic hydrocarbon-
rich wastewater from the oil industry is discharged into
natural water bodies. Detritivorous fish show the effects of
pollutants in water. Biomarkers of effect make it possible to
demonstrate exposure to xenobiotics such as polycyclic
aromatic hydrocarbons. The present study aimed to
evaluate the hepatic and erythrocyte response in
Aequidens metae, an etritivorous fish exposed to polycyclic
aromatic hydrocarbons in terms of morphological,
biochemical, and genotoxic changes.

Once fundamental difficulties such as active sites and
selectivity are fully resolved, metal-free catalysts such as 3D
graphene or carbon nanotubes (CNT) are very cost-
effective substitutes for the expensive noble metals used
for catalyzing CO2. A viable method for converting
environmental wastes into useful energy storage or
industrial wealth, and one which also addresses the
environmental and energy problems brought on by
emissions of CO2, is CO2 hydrogenation into
hydrocarbon compounds.

The bottom sediments were studied within the basins of
water bodies used for recreational purposes (e.g., bathing,
fishing, and diving) in the Silesian Upland and its periphery
in southern Poland. It was found that bottom sediments
were contaminated to varying degrees with toxic metals,
metalloids, and non-metals, as evidenced by the values of
geoecological indicators. It was concluded that the
presence of harmful elements (e.g., lead, zinc, cadmium,
chromium, strontium, and arsenic) in bottom sediments
should be considered when classifying water bodies as
suitable for recreational use.

Eucyclops are small crustaceans that are important
members of aquatic food webs. Examination of Eucyclops
populations coming from Algerian water bodies and
identified as Eucyclops cf. serrulatus showed three
morphotypes 1, 2 and 3, based on the morphometric
characters and the microcharacters. The morphotype 1
was the most abundant, collected in the East and the
West of Algeria. The morphotype 2 was sampled in the
south of the country, characterized by posterolaterally
elongated thoracic segments and the fourth thoracic
segment has cilia on its lateral angles. The morphotype 3
was found in a small temporary pond in the north and
was the smallest one.

The process of macroplastic fragmentation results in the
production of plastic particles, which threaten biota and
human health and are difficult to remove from the
environment. The global coverage and long retention
times of macroplastic waste in fluvial systems, ranging from
years to centuries, create long-lasting and widespread
potential for its fragmentation and the production of
secondary micro- and nanoplastics. However, the
pathways and rates of this process are mostly unknown,
and existing experimental data is not fully informative,
which constitutes a fundamental knowledge gap in our
understanding of macroplastic fate in rivers and the
transfer of produced microparticles throughout the
environment.

This paper explores and proposes ways to achieve robust
risk regulation in offshore drilling operations in China,
identify the factors that affect risk regulation's robustness,
and compare different regulatory regimes from various
countries (the United Kingdom, Norway, the United States,
and China). It discusses the theoretical debate between
command-and-control regulation and self-regulation,
suggesting that both modes are necessary for optimal
regulatory outcomes in China.

This paper discusses the problem of non-compliance with
fishing regulations among a segment of the Australian
fishing community. It highlights the challenges regulators
face due to limited resources and the resistance of some
fishers to educational initiatives. It also highlights the
importance of understanding the reasons for non-
compliance and fishermen's attitudes towards sanctions
and suggests that a better understanding of these factors,
informed by criminological theory, could help to promote
a culture of compliance through the effective use of
sanctions.

This study monitored the electroencephalographic activity
of northern elephant seals while diving in Monterey Bay,
California, to understand how they manage their sleep
requirements in a marine environment. The findings
revealed that the seals take short naps while diving and
average only 2 hours of sleep per day over a period of 7
months, which is comparable to the least sleep recorded
among all mammals.

This paper highlights the challenges faced by port states
during the COVID-19 pandemic when dealing with cruise
vessels carrying infected passengers. It discusses the legal
and humanitarian dilemmas, the financial burdens, and
the need for a new international legal framework to
address these issues. The text suggests that a compulsory
insurance system for medical care during pandemics
could help distribute the economic burden more fairly,
making port states more willing to accept such vessels.

This paper discusses the sustainability challenges facing
the Norwegian salmon farming industry and analyzes the
impact of a new innovation policy instrument, known as
development licenses, introduced by the Norwegian
authorities in 2015. Based on a mapping of technology
development projects and in-depth interviews, it is shown
how this policy has initiated a sustainable restructuring
process within the industry. The findings suggest that the
policy has been successful in the short term by
reconfiguring innovation networks for aquaculture
production technologies.

development of a comprehensive spatial database of man-
made structures (MMS) in the North Sea, such as oil and
gas platforms, pipelines, and wind turbines. It emphasizes
the importance of this database for informing effective
policy decisions, understanding the impact of MMS on the
ecosystem, and supporting various stakeholders, including
ecologists, engineers, policymakers, industry advisors, and
geoscientists. It also points out the current challenges due
to the lack of accurate and up-to-date metadata in existing
databases, which can lead to incorrect decisions.

This paper discusses the debate on whether focusing on
small lifestyle changes, such as reducing plastic use, can
distract from broader sustainability goals like mitigating
climate change or whether such small actions can lead to
"behavioral spillover," encouraging more significant
climate-related actions. The research findings indicate that
while messages about plastic pollution can increase
climate-related behaviors, this effect is more pronounced
when past behaviors are highlighted and is less effective
for already engaged audiences. The authors advise
caution in using plastic messaging strategies if the primary
goal is to achieve behavioral spillover for reef conservation.

This document highlights the need for a comprehensive
marine spatial planning framework in the North Sea,
particularly in light of the competing objectives of
renewable energy production (offshore wind farms) and
marine conservation (marine protected areas). It
emphasizes the importance of assessing trade-offs
between stakeholders and ecosystem health using a
spatially explicit trophic model. It also suggests that
closures to fisheries need to be carefully managed and
accompanied by additional measures to avoid negative
impacts.

This paper discusses the challenges and advancements in
modeling the noise and seabed vibrations caused by
vibratory pile driving in offshore wind farm construction. It
highlights the limitations of current models, particularly in
accurately predicting noise due to the interaction
between the pile and the sediment. It describes a study
that introduces a new model allowing for slip conditions
at the pile-soil interface, which is then verified and
analyzed to understand its impact on noise generation. It
also concludes that existing models for impact pile driving
are unsuitable for vibratory pile driving due to the critical
role of pile-soil interaction in noise generation.

02 - Residents' acceptability and response to the water-pricing policy
to reduce marine pollution caused by domestic sewage
Authors: Zhihua Xu, Chuwei Wang, Shuqin Li, and
Jingzhu Shan
This paper examines residents' acceptance of a water-
pricing policy in Qingdao, China, aimed at improving
sewage treatment technologies to reduce marine
pollution. Results show that residents can accept an
average increase of 0.90 CNY/m3 in water price, with
low-income individuals showing low acceptability. This
policy also positively influences water-saving behavior,
suggesting the need for a water-pricing policy to mitigate
sewage's negative impacts.
12 - Identification of marine oil spill pollution using hyperspectral
combined with thermal infrared remote sensing
Author: Junfang Yang, Yabin Hu, Jie Zhang, Yi Ma,
Zhongwei Li, and Zongchen Jiang
This paper investigates marine oil spill pollution types and
their impact on source tracing and disposal, using
hyperspectral and thermal infrared remote sensing data to
develop a hyperspectral recognition algorithm that,
combined with thermal infrared, can improve oil
recognition accuracy, but cannot distinguish crude oil and
high-concentration water-in-oil emulsions. This
combination can support emergency response and oil
spill monitoring in relevant departments.

The Hong Kong-Zhuhai-Macao Bridge's underwater noise
pollution may affect the distribution of local humpback
dolphins in the Pearl River Estuary. This study, which used
static passive acoustic monitoring, found that dolphin
biosonar signals were detected on 88.5% of days, with
higher activity at night and higher underwater noise
during the day. The negative correlation between
elevated underwater noise and dolphin sonar activity
suggests dolphins may avoid noisy waters for short
periods, possibly due to auditory stress.

chinensis ) near the tunnel section of the world’s longest cross-
sea bridge — the Hong Kong-Zhuhai-Macao Bridge — is
negatively correlated with underwater noise
30 - Editorial: Plastic pollution in a changing marine environment:
effects and risk
Authors: Ana Isabel Catarino, Jana Asselman, Farhan R.
Khan, and Gert Everaert
Plastic litter in marine environments accumulates and has
potential effects on biota. Estimating the risk of plastic
particles requires high-quality data on exposure and
effects. Current data gaps are crucial for identifying litter
hotspots and developing mitigation strategies.
Understanding microplastic formation mechanisms is
essential for estimating particle sizes and their potential for
ingestion. This research aims to provide high-quality data
collection, report plastic litter accumulation, investigate UV
exposure, and discuss potential interactions with climate
change
31 - High concentrations of floating neustonic life in the plastic-rich
North Pacific Garbage Patch
Authors: Fiona Chong, Matthew Spencer, Nikolai
Maximenko, Jan Hafner, , Andrew C.
McWhirter, Rebecca R. Helm
Floating life, a crucial part of the ocean's food web, is only
found in the Sargasso Sea in the Subtropical North
Atlantic gyre. This study's authors hypothesize that it is also
concentrated in other gyres with converging surface
currents. They collected samples from the eastern North
Pacific Subtropical Gyre, specifically the North Pacific
"Garbage Patch" (NPGP), and found higher densities of
floating life inside the central NPGP. This has implications
for the ecology of subtropical oceanic gyre ecosystems.
