Within the Northeastern United States, the Gulf of Maine represents some of the biologically numerous marine ecosystems on the planet — house to whales, sharks, jellyfish, herring, plankton, and tons of of different species. However at the same time as this ecosystem helps wealthy biodiversity, it’s present process speedy environmental change. The Gulf of Maine is warming sooner than 99 p.c of the world’s oceans, with penalties which can be nonetheless unfolding.
A brand new analysis initiative growing at MIT Sea Grant, known as LOBSTgER — brief for Studying Oceanic Bioecological Programs By way of Generative Representations — brings collectively synthetic intelligence and underwater pictures to doc the ocean life left susceptible to those adjustments and share them with the general public in new visible methods. Co-led by underwater photographer and visiting artist at MIT Sea Grant Keith Ellenbogen and MIT mechanical engineering PhD scholar Andreas Mentzelopoulos, the challenge explores how generative AI can increase scientific storytelling by constructing on field-based photographic information.
Simply because the Nineteenth-century digicam reworked our potential to doc and reveal the pure world — capturing life with unprecedented element and bringing distant or hidden environments into view — generative AI marks a brand new frontier in visible storytelling. Like early pictures, AI opens a inventive and conceptual house, difficult how we outline authenticity and the way we talk scientific and creative views.
Within the LOBSTgER challenge, generative fashions are educated completely on a curated library of Ellenbogen’s unique underwater pictures — every picture crafted with creative intent, technical precision, correct species identification, and clear geographic context. By constructing a high-quality dataset grounded in real-world observations, the challenge ensures that the ensuing imagery maintains each visible integrity and ecological relevance. As well as, LOBSTgER’s fashions are constructed utilizing customized code developed by Mentzelopoulos to guard the method and outputs from any potential biases from exterior information or fashions. LOBSTgER’s generative AI builds upon actual pictures, increasing the researchers’ visible vocabulary to deepen the general public’s connection to the pure world.

At its coronary heart, LOBSTgER operates on the intersection of artwork, science, and know-how. The challenge attracts from the visible language of pictures, the observational rigor of marine science, and the computational energy of generative AI. By uniting these disciplines, the group shouldn’t be solely growing new methods to visualise ocean life — they’re additionally reimagining how environmental tales may be instructed. This integrative strategy makes LOBSTgER each a analysis device and a inventive experiment — one which displays MIT’s long-standing custom of interdisciplinary innovation.
Underwater pictures in New England’s coastal waters is notoriously troublesome. Restricted visibility, swirling sediment, bubbles, and the unpredictable motion of marine life all pose fixed challenges. For the previous a number of years, Ellenbogen has navigated these challenges and is constructing a complete file of the area’s biodiversity by way of the challenge, Area to Sea: Visualizing New England’s Ocean Wilderness. This massive dataset of underwater photographs gives the inspiration for coaching LOBSTgER’s generative AI fashions. The pictures span numerous angles, lighting situations, and animal behaviors, leading to a visible archive that’s each artistically hanging and biologically correct.

LOBSTgER’s customized diffusion fashions are educated to duplicate not solely the biodiversity Ellenbogen paperwork, but in addition the creative type he makes use of to seize it. By studying from 1000’s of actual underwater photographs, the fashions internalize fine-grained particulars equivalent to pure lighting gradients, species-specific coloration, and even the atmospheric texture created by suspended particles and refracted daylight. The result’s imagery that not solely seems visually correct, but in addition feels immersive and shifting.
The fashions can each generate new, artificial, however scientifically correct photographs unconditionally (i.e., requiring no person enter/steering), and improve actual pictures conditionally (i.e., image-to-image era). By integrating AI into the photographic workflow, Ellenbogen will have the ability to use these instruments to get better element in turbid water, regulate lighting to emphasise key topics, and even simulate scenes that may be practically unimaginable to seize within the subject. The group additionally believes this strategy could profit different underwater photographers and picture editors going through related challenges. This hybrid technique is designed to speed up the curation course of and allow storytellers to assemble a extra full and coherent visible narrative of life beneath the floor.

In a single key sequence, Ellenbogen captured high-resolution photographs of lion’s mane jellyfish, blue sharks, American lobsters, and ocean sunfish (Mola mola) whereas free diving in coastal waters. “Getting a high-quality dataset shouldn’t be simple,” Ellenbogen says. “It requires a number of dives, missed alternatives, and unpredictable situations. However these challenges are a part of what makes underwater documentation each troublesome and rewarding.”
Mentzelopoulos has developed unique code to coach a household of latent diffusion fashions for LOBSTgER grounded on Ellenbogen’s photographs. Growing such fashions requires a excessive degree of technical experience, and coaching fashions from scratch is a fancy course of demanding tons of of hours of computation and meticulous hyperparameter tuning.
The challenge displays a parallel course of: subject documentation by way of pictures and mannequin improvement by way of iterative coaching. Ellenbogen works within the subject, capturing uncommon and fleeting encounters with marine animals; Mentzelopoulos works within the lab, translating these moments into machine-learning contexts that may lengthen and reinterpret the visible language of the ocean.
“The purpose isn’t to exchange pictures,” Mentzelopoulos says. “It’s to construct on and complement it — making the invisible seen, and serving to folks see environmental complexity in a means that resonates each emotionally and intellectually. Our fashions purpose to seize not simply organic realism, however the emotional cost that may drive real-world engagement and motion.”
LOBSTgER factors to a hybrid future that merges direct commentary with technological interpretation. The group’s long-term purpose is to develop a complete mannequin that may visualize a variety of species discovered within the Gulf of Maine and, ultimately, apply related strategies to marine ecosystems all over the world.
The researchers recommend that pictures and generative AI kind a continuum, quite than a battle. Pictures captures what’s — the feel, gentle, and animal habits throughout precise encounters — whereas AI extends that imaginative and prescient past what’s seen, towards what could possibly be understood, inferred, or imagined primarily based on scientific information and creative imaginative and prescient. Collectively, they provide a robust framework for speaking science by way of image-making.
In a area the place ecosystems are altering quickly, the act of visualizing turns into extra than simply documentation. It turns into a device for consciousness, engagement, and, finally, conservation. LOBSTgER continues to be in its infancy, and the group appears to be like ahead to sharing extra discoveries, photographs, and insights because the challenge evolves.
