Here on Earth, we have more detailed maps of Mars than of our own ocean, and that’s a problem. A massive force for surviving climate change, the ocean absorbs 90% of the heat caused by emissions and generates 50% of the oxygen we breathe. “We have the ocean to thank for so many aspects of our safety and well-being,” says Dawn Wright, oceanographer and chief scientist at geographic information system (GIS) provider Esri, who notes the ocean also provides renewable energy, a major food source, and a transportation corridor for not only ships but submarine internet cables.
Now, the same type of smart maps and geospatial technology guiding outer space exploration support the quest to better understand and protect our ocean. “For the first time, our knowledge of the ocean can approach our knowledge of the land,” Wright says. “We can turn the unknown deep into the known deep.”
GIS—the location intelligence technology businesses and governments use for everything from risk mitigation to crisis response, market analysis to operational efficiency—also applies to the ocean. The logic is simple: the ocean supports a sustainable planet and economy, and data-rich maps can support a sustainable ocean.
‘Tons and tons of beautiful data’
More than 80% of the ocean floor remains unmapped, yet comprehensive ocean maps will be essential for stemming the problems of overfishing, habitat destruction, pollution, and biodiversity loss. It’s easy, and at this point cliché, to say “save our ocean,” but a data-driven map compels people to see why the ocean needs saving, where to start, and what needs to be done. “Seeing the ocean in its true depth and complexity is exactly what we need if we hope to reduce the risk of critically damaging or exhausting marine resources,” Wright says.
Since its release in 2017, the world’s first 3D ocean map spurred a revolution of innovation in ocean-related data and sustainability solutions. The 3D digital ocean map sorts global water masses into 37 distinct volumetric regions, known as ecological marine units, defined by factors in ecosystem health and recovery: temperature, salinity, oxygen, and nutrient levels. Scientists, environmental managers, fishers, and shippers, as well as citizen scientists can use the map to virtually navigate and explore the ocean.
What makes the 3D map of the world’s ocean possible is the enterprise technology capable of collecting and processing data that comes in massive volume and variety. And there’s more data on the way. “This whole idea of marine robotics is one of the big future visions for the ocean,” Wright says. “Robotics and sensors and other instruments are creating tons and tons and tons of beautiful data.”
Once collected, those volumes of data go into a GIS where they are managed and processed, using artificial intelligence (AI) to quickly identify and classify information. The output of GIS, often called location intelligence, comes through as smart maps, spatial analytics, and real-time dashboards—the same kind seen across the world this past year to track and analyze the coronavirus pandemic. These GIS-powered interactive data visualization tools bring clarity even to the most complex of issues and help steer policy and commercial decisions based on a solid grasp of what’s happening now and what will happen next.
“We can even make predictions in terms of what the data will be telling us in 2030,” Wright explains. “How warm will the coast of Florida be in 2050? Will those temperatures kill off the sea grass in that area? Will those temperatures result in a red tide around Tampa that will be so toxic it will kill all of the fisheries there?”
‘The ocean is vulnerable’
Growing up on the Hawaiian Islands and working in American Samoa, Wright understands the ocean as a sacred place. That sentiment guides her work now with fellow scientists, government leaders, and business executives. “I want people to understand that the ocean is vulnerable,” Wright says. “What we’re doing to the ocean right now is having huge consequences. Our day-to-day weather and our long-term climate fully depend on the ocean.”
For Wright, the establishment and enforcement of marine protected areas, such as Cook Islands Marine Park off of New Zealand and Papahānaumokuākea Marine National Monument in the US, represent a triumph in keeping the ocean protected. So far only 7% of the ocean has been marked as protected, compared to 15% of the land. “Even though we have about 7% of the ocean protected in these parks or reserves, less than half of that is an area where you’re not allowed to fish or take the corals or take the pretty rocks,” Wright explains. “So, we have a long, long, long way to go there.”
Protected areas, predictive maps, and pleas from scientists certainly make an impact on corporate and policy decisions. Add to that increasing climate risk and global pressure for social responsibility. These incentives, and the GIS tools needed to respond, are motivating leaders to implement new initiatives.
For example, shipping companies are working to decrease greenhouse gas emissions by designing more efficient vessels, a move that furthers the sustainability cause while reducing business expense. Industries such as retail and manufacturing are putting circular economy principles in place to reclaim or recycle materials after the product has completed its original use. Aquaculture companies are selecting prime locations for responsible fish farming to help reduce overfishing, encourage aquatic ecosystem restoration, and recover endangered species.
Such efforts are moving us toward the vision of a sustainable ocean and thus a sustainable planet. Although Wright feels certain with so much advanced technology—“it’s a great time to be mapping”—what’s less certain is whether the work scientists, governments, and companies are doing will be enough or cede results soon enough.
‘The ocean isn’t too big to fail’
Concerned about mounting threats to the ocean, the United Nations has declared 2021 to 2030 the Decade of Ocean Science for Sustainable Development. “It’s like the Paris Climate Accord for the ocean,” Wright says. “To me, it’s the moonshot … to have something this focused for everybody—governments, universities, nonprofit organizations—this is a really big push.”
A number of important ocean mapping projects are already in various stages of development and execution. For example, Seabed 2030 has the ambitious goal to map the entire ocean floor by the year 2030. The Map of Biodiversity Importance shares habitat models for more than 2,200 at-risk species in the contiguous United States, featuring AI predictor layers for species viability based on development plans and environmental factors. And the Ocean Health Index annually assesses ocean health by looking at social, ecological, and economic benefits to speed progress on ocean policies.
Such projects will aid socially responsible companies (those building sustainability solutions to match business opportunities) in achieving profit while preserving the ocean. Their work often revolves around complex and real-time data, stored and processed with GIS, and presented on smart maps and data visualizations with GIS. Location intelligence helps companies—especially shipping, energy, logistics, and fishing industries—questions like the following:
- Where would offshore wind turbines have the least impact on commercial fishing?
- Where should a new transatlantic submarine communications cable go to avoid interference with scallop beds, rare deep-sea coral habitat, or sand mining areas needed for beach restoration?
- Where are appropriate areas for ships to transit in the Arctic (now that it’s no longer covered with ice year-round) to minimize the impact on sensitive ecosystems?
As the world slowly emerges from the pandemic and enters the United Nations’ Decade of Ocean Science for Sustainable Development, it can do so knowing companies, scientists, and policy makers have the power to make smarter choices for people and the planet.
Those choices will be guided by comprehensive data about the ocean, the technology to map crucial information, and the understanding how, when, and where to intervene. The linchpin will be making sustainability choices in time. “It turns out that the ocean is not too big to fail, unfortunately,” Wright says. “The good news is that it’s also not too big to fix.”

Your microbiome ages as you do—and that’s a problem
These ecosystems appear to change as we age—and these changes can potentially put us at increased risk of age-related diseases. So how can we best look after them as we get old? And could an A-grade ecosystem help fend off diseases and help us lead longer, healthier lives?
It’s a question I’ve been pondering this week, partly because I know a few people who have been put on antibiotics for winter infections. These drugs—lifesaving though they can be—can cause mass destruction of gut microbes, wiping out the good along with the bad. How might people who take them best restore a healthy ecosystem afterwards?
I also came across a recent study in which scientists looked at thousands of samples of people’s gut microbe populations to see how they change with age. The standard approach to working out what microbes are living in a person’s gut is to look at feces. The idea is that when we have a bowel movement, we shed plenty of gut bacteria. Scientists can find out which species and strains of bacteria are present to get an estimate of what’s in your intestines.
In this study, a team based at University College Cork in Ireland analyzed data that had already been collected from 21,000 samples of human feces. These had come from people all over the world, including Europe, North and South America, Asia, and Africa. Nineteen nationalities were represented. The samples were all from adults between 18 and 100.
The authors of this study wanted to get a better handle on what makes for a “good” microbiome, especially as we get older. It has been difficult for microbiologists to work this out. We do know that some bacteria can produce compounds that are good for our guts. Some seem to aid digestion, for example, while others lower inflammation.
But when it comes to the ecosystem as a whole, things get more complicated. At the moment, the accepted wisdom is that variety seems to be a good thing—the more microbial diversity, the better. Some scientists believe that unique microbiomes also have benefits, and that a collection of microbes that differs from the norm can keep you healthy.
The team looked at how the microbiomes of younger people compared with those of older people, and how they appeared to change with age. The scientists also looked at how the microbial ecosystems varied with signs of unhealthy aging, such as cognitive decline, frailty, and inflammation.
They found that the microbiome does seem to change with age, and that, on the whole, the ecosystems in our guts do tend to become more unique—it looks as though we lose aspects of a general “core” microbiome and stray toward a more individual one.
But this isn’t necessarily a good thing. In fact, this uniqueness seems to be linked to unhealthy aging and the development of those age-related symptoms listed above, which we’d all rather stave off for as long as possible. And measuring diversity alone doesn’t tell us much about whether the bugs in our guts are helpful or not in this regard.
The findings back up what these researchers and others have seen before, challenging the notion that uniqueness is a good thing. Another team has come up with a good analogy, which is known as the Anna Karenina principle of the microbiome: “All happy microbiomes look alike; each unhappy microbiome is unhappy in its own way.”
Of course, the big question is: What can we do to maintain a happy microbiome? And will it actually help us stave off age-related diseases?
There’s plenty of evidence to suggest that, on the whole, a diet with plenty of fruit, vegetables, and fiber is good for the gut. A couple of years ago, researchers found that after 12 months on a Mediterranean diet—one rich in olive oil, nuts, legumes, and fish, as well as fruit and veg—older people saw changes in their microbiomes that might benefit their health. These changes have been linked to a lowered risk of developing frailty and cognitive decline.
But at the individual level, we can’t really be sure of the impact that changes to our diets will have. Probiotics are a good example; you can chug down millions of microbes, but that doesn’t mean that they’ll survive the journey to your gut. Even if they do get there, we don’t know if they’ll be able to form niches in the existing ecosystem, or if they might cause some kind of unwelcome disruption. Some microbial ecosystems might respond really well to fermented foods like sauerkraut and kimchi, while others might not.
I personally love kimchi and sauerkraut. If they do turn out to support my microbiome in a way that protects me against age-related diseases, then that’s just the icing on the less-microbiome-friendly cake.

The Download: circumventing China’s firewall, and using AI to invent new drugs
As protests against rigid covid control measures in China engulfed social media in the past week, one Twitter account has emerged as the central source of information: @李老师不是你老师 (“Teacher Li Is Not Your Teacher”).
People everywhere in China have sent protest footage and real-time updates to the account through private messages, and it has posted them, with the sender’s identity hidden, on their behalf.
The man behind the account, Li, is a Chinese painter based in Italy, who requested to be identified only by his last name in light of the security risks. He’s been tirelessly posting footage around the clock to help people within China get information, and also to inform the wider world.
The work has been taking its toll—he’s received death threats, and police have visited his family back in China. But it also comes with a sense of liberation, Li told Zeyi Yang, our China reporter. Read the full story.
Biotech labs are using AI inspired by DALL-E to invent new drugs
The news: Text-to-image AI models like OpenAI’s DALL-E 2—programs trained to generate pictures of almost anything you ask for—have sent ripples through the creative industries. Now, two biotech labs are using this type of generative AI, known as a diffusion model, to conjure up designs for new types of protein never seen in nature.
Why it matters: Proteins are the fundamental building blocks of living systems. These protein generators can be directed to produce designs for proteins with specific properties, such as shape or size or function. In effect, this makes it possible to come up with new proteins to do particular jobs on demand. Researchers hope that this will eventually lead to the development of new and more effective drugs.

Methodology: The Blue Technology Barometer 2022/23
Now in its second year, the Blue Technology Barometer assesses and ranks how each of the world’s largest
maritime economies promotes and develops blue (marine-centered) technologies that help reverse the impact of
climate change on ocean ecosystems, and how they leverage ocean-based resources to reduce greenhouse gases and
other effects of climate change.
To build the index, MIT Technology Review Insights compiled 20 quantitative and qualitative data indicators
for 66 countries and territories with coastlines and maritime economies. This included analysis of select
datasets and primary research interviews with global blue technology innovators, policymakers, and
international ocean sustainability organizations. Through trend analysis, research, and a consultative
peer-review process with several subject matter experts, weighting assumptions were assigned to determine the
relative importance of each indicator’s influence on a country’s blue technology leadership.
These indicators measure how each country or territory’s economic and maritime industries have affected its
marine environment and how quickly they have developed and deployed technologies that help improve ocean
health outcomes. Policy and regulatory adherence factors were considered, particularly the observance of
international treaties on fishing and marine protection laws.
The indicators are organized into four pillars, which evaluate metrics around a sustainability theme. Each
indicator is scored from 1 to 10 (10 being the best performance) and is weighted for its contribution to its
respective pillar. Each pillar is weighted to determine its importance in the overall score. As these research
efforts center on countries developing blue technology to promote ocean health, the technology pillar is
ranked highest, at 50% of the overall score.
The four pillars of the Blue Technology Barometer are:
Carbon emissions resulting from maritime activities and their relative growth. Metrics in this pillar also
assess each country’s efforts to mitigate ocean pollution and enhance ocean ecosystem health.
Efforts to promote sustainable fishing activities and increase and maintain marine protected areas.
Progress in fostering the development of sustainable ocean technologies across several relevant fields:
- Clean innovation scores from MIT Technology Review Insights’ Green Future Index 2022.
- A tally of maritime-relevant patents and technology startups.
- An assessment of each economy’s use of technologies and tech-enabled processes that facilitate ocean
