Expertise
The PIXSEA group is involved at every stage of environmental studies, deploying its expertise and skills to conduct inventories for public authorities as well as monitoring and impact assessments of industrial projects for private companies.
Marine megafauna monitoring
A team of experts with strong naturalist and ecological skills:
Identification of marine megafauna species (seabirds, marine mammals, sea turtles, etc.)
Conducting aerial surveys using the SAMM protocol, aboard bubble-windowed aircraft for marine megafauna observation
Expertise in detecting and identifying marine megafauna from aerial imagery
High-resolution aerial image acquisition at sea
Expertise in aerial image acquisition at sea:
Design of aerial imaging systems specifically adapted for marine observation and its conditions
Implementation and continuous improvement of methods to reduce specular reflections and blur effects
Ongoing development of solutions to achieve optimal image resolution
Development of neural networks for image detection and classification
Artificial intelligence supporting environmental monitoring:
Regular updating of the neural network with high-resolution images from previous campaigns taken under similar conditions
Detection and identification of marine megafauna species or species groups, with a high recognition rate
Detection and identification of anthropogenic activities and pollution
Verification of a portion of the photographs and AI-generated results by naturalist experts
Data analysis and cartography
Data analyses conducted spatially and over various temporal scales (monthly, seasonal, yearly or over multiple years):
Spatial distribution of observations, abundance or density by species or species groups using distance sampling and kriging interpolation when necessary
Comparison of multi-species distributions
Species richness of marine megafauna
Spatial distribution of behaviors (feeding, resting, hunting, flying, etc.) and other information (carcasses, juveniles, etc.)
Spatial distribution of human activities (fishing, boating, transport, recreation) and pollution (oil spills, marine debris, etc.)
Biological interpretation of results and contextualization based on existing knowledge and literature
Drafting of detailed reports on the environmental impacts of human activities and marine biodiversity conservation issues:
Biodiversity inventories
Baseline environmental assessments prior to project implementation
Project impact assessments and mitigation measures
Monitoring reports during construction and post-implementation phases
Preparation of regulatory documents
Delivery of raw and processed data
Publication of scientific articles as part of R&D projects
