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.

The Greek Seas are extensively exposed to the proliferation
of marine alien species. At least 242 alien species have
been reported while their introduction rate is increasing.
Some species severely impact native ecosystems. The
spatio-temporal proliferation of these species outside their
natural boundaries depends on several parameters,
including their biological characteristics, native distribution
range, introduction pathway, and time of initial
introduction. Knowing the current and potential alien
species distribution is essential for implementing effective
management actions.

Underwater sampling must balance time-efficient and
standardized data to compare areas and times. The roving
diver survey involves divers meandering and actively
searching for species and has been useful for producing
fish species lists but has seldom been implemented for
benthic taxa. In this study, the authors used this non-
destructive technique to register species associated with
kelp forests at the sub-Antarctic Bécasses Island (Beagle
Channel, Argentina), detecting numerous species while
providing the first multi-taxa inventory for the area.

Plastic entering the environment is a growing threat for
ecosystems. the authors estimate the annual mass of
known Dutch plastic waste generated and littered and
where it ends up. The author used two methods: a
material flow analysis of plastic waste separately collected
from 13 economic sectors, and estimate the amount sent
to processing plants or exported and a mismanagement
model from observations of litter plus estimates of
inadequately managed exported plastic scraps entering
the environment abroad.

Studies investigating different effects on the fragmentation
of plastics have mostly disregarded a sufficient mechanical
component for fragmentation, focusing on degradation
by UV radiation. Therefore, this study investigated the
impact of the mechanical fragmentation drivers, wave
impact, and sediment abrasion on the fragmentation of
expanded polystyrene (EPS), high-density polyethylene
(PE-HD), and polyethylene terephthalate (PET) particles

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.

Most underwater explosions show characteristics of a
bubble pulse and reverberation effects. To specifically
identify the cause of an underwater explosion, it is most
important to find a bubble pulse and reverberation effects
using spectral and cepstral analyses. For a very shallow
underwater explosion, spectral analysis is preferable to
cepstral analysis. Time-domain analyses show bubble
pulses as well as positive polarities of the first P-wave
arrivals on the vertical component, and frequency-
domain spectral analyses also clearly reveal the bubble
pulse and reverberation effects. This study includes
comparative studies including a Russian underwater
nuclear explosion and US Navy shock trials.

Although satellites are very accurate in monitoring the
melting glaciers, they provide scarce or no information
about under-ice water characteristics. However, mobile
platforms would represent a substantial integration of the
Ice Tethered Profilers, which move slowly with the sea ice
without possibility to select the specific area where the
data are collected. This paper givies an overview on how
capabilities provided by underwater Positioning,
Navigation and Timing (PNT) technologies can support
Climate Change Monitoring.

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.

Active restoration actions are becoming increasingly
common for the recovery of degraded ecosystems.
However, establishing when an ecosystem is fully restored
is rarely achieved, since the recovery of entire communities
requires long-term trajectories. The lack of evidence of
success is even more severe in marine ecosystems,
especially in the context of macroalgal forests, where,
beyond the vegetation structure and species diversity,
there is no approximation to determine the recovery of
the overall functionality.
The authors used a trait-based approach to assess the
recovery ten years after the initiation of a restoration
action in a marine macroalgal forest.

Deoxygenation of the ocean often results in the formation
of Oxygen Minimum Zones (OMZ): large domains where
the abundance of oxygen is much lower than that in the
surrounding oceanic environment. Factors and processes
resulting in OMZ formation remain controversial. The
authors propose a conceptual model of coupled plankton-
oxygen dynamics that, apart from the plankton growth
and oxygen production by phytoplankton, also considers
the difference in timescales between phyto- and
zooplankton.

Offshore wind energy is environmentally friendly for
humans, but it may not be so for aquatic life. Underwater
noise and seabed vibrations are generated during the
construction, maintenance, operation and
decommissioning of offshore wind farms. The potential
impact of the generated noise and the seabed vibrations
on aquatic species may hinder the further deployment of
offshore wind farms and marine ranching.

To ensure optimal feed intake, growth, and general fish
health in aquaculture sea cages, interactions between
drivers that affect oxygen conditions need to be
understood. The main drivers are oxygen consumption
and water exchange, caused by flow through the cage.
Swimming energetics in rainbow trout (Oncorhynchus
mykiss) in normoxia and hypoxia at 10, 15, and 20 C
degrees were determined. Using the determinations, a
conceptual model of oxygen conditions within sea cages
was created.

Many marine infrastructure projects increase
environmental impact during the construction and
operational phases due to excessive noise. The lack of
standardized methods for assessing and predicting
underwater noise increases the risk of adverse changes to
the marine environment. This study reviews methods for
modeling the impact of underwater noise as part of
marine project planning and identifies the need for noise
mitigation measures.

Since 2016, guidelines from the Danish Energy Agency
have addressed underwater noise from offshore wind
farm construction in Danish waters. The guidelines were
updated in 2022 to include technical methods for
numerical prognosis and on-site measurements.
Compliance is determined based on acoustic criteria such
as Permanent Threshold Shift (PTS) and behavioral impact.
Auditory frequency-weighted levels are used as the basis
for these criteria.

The expansion of offshore wind farms overlaps with
protected marine mammal habitats, and there are
concerns for small cetaceans, such as harbor porpoises,
due to the potential for injury from impulsive noise during
turbine foundation installation. Current risk assessment
methods compare predicted noise levels with estimates of
baseline animal density. However, pre-piling activities may
displace animals, potentially reducing the risk of injury.

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 study analyzes the current state of monitoring
practices for floating photovoltaic (FPV) plants,
highlighting the need for standardized guidelines and
criteria for water quality monitoring and management. It
discusses the challenges and environmental impacts
associated with FPV systems, the importance of
monitoring key physico-chemical parameters, and the
potential of autonomous solutions for environmental
impact monitoring to identify gaps in the existing literature
and propose the development of a cohesive framework
for effective monitoring of FPV systems.

The paper intends to describe and promote the features
and capabilities of the "plastic parcels" Python package to
inform about its functionalities for simulating the transport
and dispersion of plastics in the ocean, its integration with
the parcels framework, and its adaptability for various
computational environments. It also highlights the
package's modular design, user-friendly interface, and
potential applications in research and development
related to ocean plastic pollution modeling. Additionally, it
outlines future goals for the package, such as support for
macroplastics and cloud platform integration.
