Operational Object-Detection Models For Detection and Monitoring with OCIANA™

On March 3, 2023, the United Nations Intergovernmental Conference on Marine Biodiversity of Areas Beyond National Jurisdiction reached agreement on a historic new maritime biodiversity treaty. The so-called “High Seas Treaty” focuses on marine conservation, and is integral to achieving conservation outcomes with the Global Biodiversity Framework, an international agreement signed in Montreal in 2022 to protect a third of the entire planet’s biodiversity.

International agreements go a long way to providing direction and resources to achieve broad societal goals, but operationalizing these agreements requires much more detailed and concrete work. In the maritime sector, conservation can mean a variety of things: from increased monitoring of vessel operations and impacts in port waters, optimizing vessel performance and port resources, to adjusting routes to mitigate impacts on protected marine species and ecosystems. Each of these approaches can gain considerably from digitalization and the leveraging of available data and AI-based models. At GSTS, we have developed solutions to aid in the understanding of environmental impacts, and more importantly, how vessel operators and ports can take action within the scope of their day-to-day activities to protect marine wildlife.

On the eastern seaboard of North America, one marine conservation issue has been of critical importance to all vessels operating in navigable waters: the plight of the North Atlantic Right Whale (NARW). Since a critical event where 12 whales died entangled in fishing nets in the Gulf of St. Lawrence in 2017, efforts have been stepped up to provide extensive protection measures in order to give the species the best chance at recovery. Government authorities, seafarers and the fishing industry have all been highly involved in these efforts to avoid collisions and net entanglements. A key missing piece of data is knowing where whales are at any given time and notifying nearby vessel operators quickly enough to adjust speed and course to prevent collisions.

GSTS brings unique expertise to this problem, with significant experience using high resolution satellite imaging for vessel detection, and a world-class vessel tracking and analytics platform OCIANA™. The idea was struck –

“Can we adapt our vessel detection AI models to instead identify whales at surface, and bring this data into an operational vessel tracking system?”

Unlike many studies, which classify satellite data for conservation tasks, which end up as published papers with limited real-world utility, GSTS developed an operational model to detect, validate, and integrate space-based whale detections into its maritime AI platform.

Working as a team as part of the Canadian Space Agency’s SmartWhales programme, GSTS has created a novel whale detection and monitoring system. Data sources from a variety of satellite providers can be used to screen and detect whales if they exist at or just below the ocean surface. Data are ingested into OCIANA™ and processed into a form suitable for ‘object detection’ models (i.e., the same technology that can automatically identify people in your mobile phone’s photos). Here the task of detecting and labelling objects in an image is made significantly more difficult because of the sparsity of samples for model training: whales spend most of their time below the surface, and for NARW with a population estimated at below 350 individuals, even spotting one is rare. This issue was solved by increasing the number of samples using two different methods. Firstly, an exhaustive search

and through partnerships in the whale monitoring and research community within and outside of the SmartWhales programme, a wide array of samples were obtained to provide a representative suite of whales as seen from space, in a variety of conditions. Concurrently, image augmentation methods were used to artificially increase the sample size available for model training. Through the combined effect of these strategies, a model could be trained with high accuracy for detection of NARW from satellite imagery.

OCIANA™: Making space-based detections useful for achieving conservation outcomes 

A model is only useful if the information generated from the model is used to enhance decision-making or achieve a desired outcome. This is especially true in a context such as endangered species conservation, where all efforts must be made to act quickly and consistently. Deploying AI models as operational tools is an extremely challenging task: data ingestion pipelines need to be developed, models deployed, data orchestration pipelines created, parameter files created, UI elements built and configured, and results need to be continually monitored and issues that arise fixed. Moving from a theoretical model to an operational model makes all the difference for achieving concrete conservation goals, and in this case, having the best chance to detect, monitor, and conserve NARW.

Of secondary importance to making models useful, is to bring model results into a format that a decision-maker can use. Here, we deployed our whale detection model into OCIANA™, GSTS’ unique maritime AI platform. Several additional capabilities were developed including the implementation of a dynamic whale risk model which incorporated environmental data on predicted location and abundance of its primary food source (copepods of the genus Calanus), as well as historical vessel traffic. For detections that occurred we could use vessel path prediction tools to look for potential collision risks. Such data provides unprecedented intelligence to seafarers and navigators operating in NARW habitat. Through the integration of several key data sources with AI-based models and our maritime AI platform, concrete outcomes can be achieved in terms of enhanced operational decision-making to reduce risks to NARW. 

Artificial intelligence provides a brand new set of tools to generate insights into some of the world’s most pressing problems. However, the tools themselves are not enough: the information generated from AI models must be integrated with other models and data sources and delivered with intuitive user interfaces. GSTS has developed world-leading capabilities in maritime AI, and can bring these tools together into bespoke solutions – to reduce GHG emissions, to reduce maritime risks, and even to help save the whales.
