How Artificial Intelligence is Transforming Ocean Conservation and Marine Research

One of the biggest challenges in marine biology is identifying and monitoring species, especially given the sheer scale and diversity of ocean ecosystems. AI has transformed this process by enabling the automatic identification of marine species using images, sonar data, and environmental DNA (eDNA).

For instance, machine learning algorithms trained on underwater images can accurately distinguish between species, even in cases where subtle differences make manual identification challenging. This approach is invaluable for tracking endangered species, assessing population sizes, and studying behavioural patterns.

Furthermore, AI-powered image recognition is being used in coral reef monitoring. By automatically analysing images of reefs taken by divers, drones, or underwater robots, AI can help track coral health over time. This is crucial in identifying stressed or bleaching corals early, which in turn aids conservationists in making timely interventions.

The effects of climate change are particularly evident in ocean environments, with warmer waters affecting marine life, altering currents, and increasing the frequency of extreme weather events. AI excels at predictive modelling and is proving instrumental in forecasting the impact of these changes on marine ecosystems. By analysing historical data on ocean temperatures, acidity levels, and current flows, machine learning models can predict changes to habitats and species distributions.

For instance, AI-driven models can anticipate the migration patterns of fish populations as they move in response to temperature shifts. These insights are essential for fisheries management, allowing for proactive strategies that protect both marine biodiversity and the livelihoods of communities dependent on fishing. In addition, AI models can forecast the occurrence of harmful algal blooms, which can devastate fish stocks and threaten human health. These predictions give authorities time to implement preventive measures, thereby minimising ecological and economic damage.

Despite advancements in oceanography, much of the ocean, especially the deep sea, remains unexplored. Autonomous Underwater Vehicles (AUVs) equipped with AI technology are filling this gap by venturing into previously inaccessible areas and collecting valuable data on deep-sea ecosystems. AUVs can be programmed to navigate challenging terrains, map the ocean floor, and capture high-resolution images of underwater habitats.

AI-powered AUVs have already discovered new species and ecosystems, expanded our understanding of deep-sea biodiversity, and monitored environments impacted by human activity, such as seabed mining and oil drilling. These data-collection missions help researchers form a clearer picture of how human activities are affecting ocean health on a broad scale and provide evidence for policymakers to develop responsible management practices for these areas.

Additionally, AI enhances the efficiency of AUV missions by processing vast amounts of data in real time. Advanced algorithms can analyse collected data onboard, identifying points of interest such as rare species or unusual formations, and alert researchers immediately. This reduces the time and cost associated with post-mission data analysis and allows for adaptive exploration in real time.

Overfishing poses a serious risk to ocean ecosystems, with certain fish populations declining at an alarming rate. AI is playing a key role in promoting sustainable fishing practices and supporting fisheries management. AI-powered tools can monitor fish populations, track fishing activities, and even identify illegal fishing practices.

Some AI systems use data from vessel tracking systems to detect suspicious behaviour indicative of illegal fishing, such as trawling in protected areas. This helps authorities take swift action against unsustainable practices and better protect marine resources. Additionally, AI models can predict the optimal harvest times for specific fish species based on population data, environmental conditions, and migration patterns. This helps prevent overfishing while ensuring a stable supply of fish for the industry and local communities.

AI is also being used to enhance aquaculture, or fish farming. Machine learning models can monitor water quality, optimise feeding schedules, and predict disease outbreaks, which increases the efficiency and sustainability of fish farms. By improving the management of these operations, AI contributes to the reduction of pressures on wild fish populations and promotes more sustainable seafood production.
