Abstract:
Wind power plants are considered an ecologically-clean
source of energy. However, manufacturing processes
cannot be treated that way. Manufacturing processes
consume huge amounts of electrical and thermal energy
and a significant quantity of materials, e.g., steel, polymers,
oils, and lubricants. All of the above could be potentially
harmful to the environment. There are not many works
and publications regarding the life-cycle analysis of wind
power plants. This study’s objective is to use LCA (Life
Cycle Assessment) to the manufacturing and utilization of
a specific drag force-driven wind turbine.

Abstract:
The conversion of wind kinetic energy into electricity in
innovative wind power plants emits practically no harmful
substances into the environment. However, the
production stage of its components requires a lot of
energy and materials. The biggest problem during the
production planning process of an innovative wind power
plant is the selection of materials and technologies and,
consequently, the waste generated at this stage.
Therefore, this publication aimed to conduct an
environmental analysis of the life cycle of elements of a
wind turbine through the life cycle assessment (LCA)
method.

Abstract:
Underwater noise has been identified as relevant pollution
affecting marine ecosystems in different ways. Despite the
numerous studies performed over the last few decades
regarding the adverse effect of underwater noise on
marine life, a lack of knowledge and methodological
procedures still exists, and results are often tentative or
qualitative. A monitoring methodology for the behavioral
response of bluefin tuna (Thunnus thynnus) when
exposed to ship and wind turbine operational noises was
implemented and tested in a fixed commercial tuna
feeding cage in the Mediterranean sea.

Abstract:
The North Sea basin is one of the busiest maritime areas
globally, with a considerable number of anthropogenic
pressures impacting the functioning of the marine
ecosystem. Due to growing EU ambitions to deploy large
offshore Wind Farm Projects (OWF) as part of the 2050
renewable energy roadmap, there is a key need for a
holistic understanding of OWF's potential impacts on the
marine ecosystem. The authors propose a holistic
Cumulative Effect Assessment methodology, applied using
a geospatial open-source software, to assess impacts of
OWF related pressures on selected seabed habitats, fish,
seabird, and mammal species.

Abstract:
Some species of bats migrate over long distances
between their summer roosts and winter areas.
During migration, many man-made obstacles, such as
wind farms, can pose a collision risk for bats. As it is
known that bats can fly over the open sea during
migration, and offshore wind farms can also be
problematic. We studied the presence of bats during
migration at several North Sea locations with the aim
of understanding the weather conditions triggering
bat migration at sea.

Abstract:
Anthropogenic underwater noise is a major conservation
problem that severely impacts marine species in all oceans.
Noise comes from offshore construction, transport as well
as resource exploration and extraction and adds to the
cumulative environmental impacts from other
anthropogenic pressures. The EU Marine Strategy
Framework Directive requires anthropogenic noise to be
at levels that do not adversely affect the marine
environment.
However, the focus has been on monitoring with no yet
widely agreed ways to assess whether good
environmental status is being achieved with respect to
underwater noise.

Abstract:
The extent of intra-annual turnover in phytoplankton
communities is directly associated with the overall diversity.
However, the understanding of the underlying causes and
effects of intra- annual turnover remains limited.
The authors of this study performed a two-season
investigation of the phytoplankton composition in the
lakes of the Yangtze River catchment in China in spring
and summer 2012, which covered a regional spatial scale.

Recent advances in deep-sea exploration with underwater
vehicles have led to the discovery of vertical environments
inhabited by diverse sessile fauna. However, despite their
ecological importance, vertical habitats remain poorly
characterized by conventional downward-looking survey
techniques. The authors present a high-resolution 3-
dimensional habitat map of a vertical cliff hosting a
suspension-feeding community at the flank of an
underwater glacial trough in the Greenland waters of the
Labrador Sea. A Remotely Operated Vehicle (ROV) with a
high-resolution multibeam echosounder was used to map
out the topography of the
deep-sea terrain, including the backscatter intensity. The
navigational accuracy was improved by combining the
USBL and the DVL navigation of the ROV. Multi-scale
terrain descriptors were derived and assigned to the 3D
point cloud of the terrain.

Abstract:
The intelligent underwater laboratory is designed to study
the properties of water, polluting factors with the
determination of the source of pollution. The laboratory
consists of a self-propelled autonomous vehicle with a
three-propulsion system and a static immersion and ascent
system. The multi-propulsion control system enables
maneuverability of the device. The solution of the
positioning problem by adjusting the coefficients and
obtaining new maneuverable capabilities of the device
provides performing the inspection on the bottom of the
vessel, the screw part, and taking water samples.

Echolocation signals of wild beluga whales
(Delphinapterus leucas) were recorded in 2013 using a
vertical, linear 16-hydrophone array at two locations in the
pack ice of Baffin Bay, West Greenland. Individual whales
were localized for 4:42 minutes of 1:04 hours of
recordings. Clicks centered on the recording equipment
(i.e. on-axis clicks) were isolated to calculate sonar
parameters.

Belugas (Delphinapterus leucas) and narwhals (Monodon
monoceros) are highly social Arctic toothed whales with
large vocal repertoires and similar acoustic profiles. Passive
Acoustic Monitoring (PAM), which uses multiple
hydrophones over large spatiotemporal scales, has been a
primary method to study their populations, particularly in
response to rapid climate change and increasing
underwater noise.

This document is a thesis that discusses the undulatory
swimming of aquatic animals at high Reynolds numbers,
where the inertial forces predominate. Aquatic
locomotion involves an intricate interaction between a
swimmer and its environment. Therefore, understanding
this process requires considering the fluid-structure
interaction of the swimmer moving within a fluid and the
sensory perception that feeds back its motile activity.

Shipping is a primary contributor to anthropogenic noises,
which have increased faster than the size of the world
fleet. Despite their potentially harmful impacts on marine
fauna, the subject currently has a low priority over other
concerns, such as greenhouse gas (GHG) emissions.
Moreover, the absence of (international) policy and noise
limits is slowing progress on mitigation. Nevertheless,
efforts are being made to increase attention to the subject,
exemplified by the recent agreement at the International
Maritime Organisation (IMO) to review existing guidelines
and propose future work.

Solar panels have a maximum life of 20 to 25 years and
can release toxic substances that can be dangerous and
pollute the environment beyond these limits. For this
reason, they must be appropriately recycled after their end
of life. In this paper, the authors focus on the various
approach for recycling solar panel and their effectiveness.

Chemical pollution, i.e. the release of anthropogenic
chemical substances into the environment, is a driver of
biodiversity loss. Although this issue has been widely
investigated in high-income countries of temperate
regions, there is a lack of data for tropical areas of middle-
or low-income countries, such as those in Eastern Africa.
A contribution in systemising the scientific literature related
to this topic is, therefore, urgently needed.

The increasing underwater noise generated by
anthropogenic activities has been recognized as a
significant and pervasive pollution in the marine
environment. Marine mussels are a family of sessile bivalves
that attach to solid surfaces via the abyssal threads. They
are widely distributed along worldwide coastal areas and
are of great ecological and socio-economic importance.
Studies found that anthropogenic noise negatively
affected many biological processes of marine organisms.
However, the potential impacts of anthropogenic noise
on mussel byssal attachment remain unknown.

This paper highlights the current state of research on
decommissioning oil and gas installations, identifies gaps
in ecological knowledge, and proposes areas for further
research. It emphasizes the need for a more
comprehensive understanding of the ecological impacts
of decommissioning, beyond just biodiversity, to include
aspects such as eco-toxicology, structural integrity, and
connectivity. This broader research focus is suggested to
better inform sustainable and equitable development
choices in the transition from offshore oil and gas to
marine renewable energy sectors.
