New Underwater Tracking Method Helps Save Critically Endangered Skates
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Scientists have developed a new statistical method to track underwater animals like the critically endangered flapper skate, enabling more accurate conservation efforts by combining acoustic detection data with depth measurements.
📈 One key stat: Flapper skate can grow over two meters long and weigh more than 100kg, potentially living for over 40 years, making their successful tracking crucial for preserving this ancient species.
💬 One key quote: “We treat animals as ‘particles’ that can swim around and reproduce or dwindle. Particles that move in ways that align with the data we collected are more prolific breeders and come to dominate the (digital) population.”
1️⃣ The big picture: Scientists have created a breakthrough method to track marine animals underwater where satellite technology doesn’t work. The new approach uses a powerful statistical technique that treats animals as ‘particles’ that can be tracked in three dimensions by combining data from acoustic transmitters and depth sensors. This innovation specifically helps monitor the critically endangered flapper skate, the world’s largest skate species found in Scotland’s waters. By integrating multiple data sources, researchers can now create detailed maps of animal movements in areas where traditional tracking methods fail, giving conservation efforts much-needed precision.
2️⃣ Why is this good news: This tracking breakthrough enables scientists to verify that flapper skates spend significant time within protected marine areas, confirming the effectiveness of existing conservation measures. The technology reveals specific hotspots beyond protected zones where additional conservation efforts might benefit these critically endangered creatures. Marine biologists can now build more comprehensive pictures of underwater animal behaviors, habitat preferences, and movement patterns to inform targeted conservation actions. The statistical approach borrows techniques from military and aerospace applications, demonstrating how cross-disciplinary methods can solve complex ecological challenges in marine environments.
3️⃣ What’s next: Researchers are refining their methods to reduce computing time while making the software more accessible. The team plans to use this technology to identify egg nurseries crucial for flapper skate reproduction. They’re also developing immersive virtual reality experiences to help people understand the lives of deep-sea animals.
