00:00:06.879 --> 00:00:10.240
Welcome to the Educational Passages Podcast.
00:00:10.480 --> 00:00:20.320
Educational Passages is a nonprofit organization that seeks to connect people around the world to the ocean and each other through unique global experiences.
00:00:20.559 --> 00:00:22.800
I'm your host, Cassie Stymist.
00:00:23.440 --> 00:00:25.600
Welcome everybody to Season 4.
00:00:25.760 --> 00:00:37.200
Get ready to set sail on a brand new adventure as we launch our Imagine This series, where the magic of mini boats come alive through the voices and visions of those who make it all possible.
00:00:37.439 --> 00:00:48.799
In this series, each episode will paint a vivid picture of discovery, connection, and curiosity, not just tracking the voyages, but exploring the challenges and unexpected outcomes behind them.
00:00:49.119 --> 00:00:52.799
Now press play, close your eyes, and imagine this.
00:00:53.759 --> 00:00:56.000
It's late fall on Cape Cod.
00:00:56.159 --> 00:00:57.679
The wind is shifting.
00:00:57.920 --> 00:00:59.840
The water is getting colder.
00:01:00.079 --> 00:01:03.920
And out in the bay, sea turtles are becoming cold stunned.
00:01:04.239 --> 00:01:06.719
Wait, did you even know they were here?
00:01:06.959 --> 00:01:11.120
There are actually four species of sea turtles that come here during the summer.
00:01:11.439 --> 00:01:13.680
All are threatened or endangered.
00:01:13.920 --> 00:01:24.879
They come here to eat, but when water temperatures drop below fifty five degrees Fahrenheit, they get too cold to move, so they drift, carried by currents they can't control.
00:01:25.359 --> 00:01:29.439
They're unable to swim out of the bay and back home to warmer water.
00:01:29.599 --> 00:01:37.200
So they wash up on the beaches where volunteers are walking, scanning the shoreline, hoping to find them in time to save them.
00:01:37.519 --> 00:01:46.319
Mass Audubon volunteers have been patrolling these beaches since 1979, day and night during the stranding season.
00:01:46.640 --> 00:01:51.840
Most of the turtles are juvenile campsridlies, the smallest and rarest.
00:01:52.159 --> 00:02:03.040
You are sitting in a classroom and learning about this, but instead of just being told about it, the teacher helps you see it, not on a PowerPoint slide, but in the water.
00:02:03.280 --> 00:02:05.760
That's where the mini boats and drifters come in.
00:02:05.920 --> 00:02:08.479
The Cape Cod Sea Turtle Project.
00:02:08.800 --> 00:02:22.159
Small, drifters about the same size as a sea turtle, and six foot long uncrewed sailboats, launched into the ocean with only GPS transmitters that report back their locations as they move.
00:02:22.479 --> 00:02:25.280
Designed to move perfectly with the wind and currents.
00:02:25.520 --> 00:02:28.240
Think of it as sail up and sail down.
00:02:28.479 --> 00:02:32.319
A sail above the water catches wind, like a mini boat.
00:02:32.560 --> 00:02:36.479
A sail below the surface follows currents, like a drifter.
00:02:36.960 --> 00:02:40.639
It's kind of like a message in a bottle, but way better.
00:02:40.960 --> 00:02:45.520
Student built from a kit, customized by each classroom.
00:02:45.759 --> 00:02:51.039
Most mini boats are launched into the Big Blue to connect classrooms across the globe.
00:02:51.360 --> 00:02:59.360
Educational passages mini boats have actually landed in over thirty six countries so far, thanks to hundreds of schools over the years.
00:02:59.599 --> 00:03:07.759
But boats like the Riptide and Rockstar are built with a special purpose to investigate those sea turtle strandings.
00:03:08.080 --> 00:03:08.719
Why?
00:03:09.039 --> 00:03:11.919
Because, well, they move just like the turtles.
00:03:12.159 --> 00:03:17.199
Wind affects their movement, and more information is needed to help them survive.
00:03:17.439 --> 00:03:24.639
So you work with the Mass Audubon, NOAA, the Gulf of Mean Lobster Foundation, and others to help them with their research.
00:03:24.879 --> 00:03:29.120
This is not learning from a textbook, it's learning by doing.
00:03:29.439 --> 00:03:32.560
And link to the standards in a very unique way.
00:03:32.800 --> 00:03:36.800
You get to see firsthand just how the ocean moves.
00:03:37.199 --> 00:03:47.599
You build the tools, guided by the best teachers who bring ocean science to life, and supported by researchers, engineers, and community partners.
00:03:47.840 --> 00:03:52.719
It started back in 2016 with launching the Rockstar Miniboat.
00:03:52.879 --> 00:03:56.719
Not just to get location, which is great, but temperature too.
00:03:56.960 --> 00:03:59.840
What's happening in the water and at the surface?
00:04:00.080 --> 00:04:03.759
The Rockstar was deployed off Corporation Beach in Dennis.
00:04:03.919 --> 00:04:09.599
It crossed the bay in just 10 hours and landed in Truro and collected data.
00:04:09.919 --> 00:04:10.719
Success.
00:04:11.039 --> 00:04:13.680
The very first mini boat with sensors.
00:04:14.479 --> 00:04:19.439
The season continued with a few dozen deployments of drifters from the student drifter program.
00:04:20.079 --> 00:04:23.680
More were launched in 2017 and 2018.
00:04:24.240 --> 00:04:27.120
In 2019, the project had grown.
00:04:27.439 --> 00:04:35.920
Student drifters, wind turtles, and the miniboat Riptide were all launched into the bay multiple times to help with this research.
00:04:36.160 --> 00:04:38.560
And they all had interesting results.
00:04:38.879 --> 00:04:45.920
The Miniboat crossed the bay in just four hours before the deployers even got home that day.
00:04:46.160 --> 00:04:49.040
That showed how powerful the wind really is.
00:04:49.360 --> 00:04:53.680
The drifters and miniboat were relaunched multiple times during November that year.
00:04:53.920 --> 00:04:57.600
The work was even published later in a scientific paper.
00:04:58.079 --> 00:05:02.800
In the fall of 2022, Falmouth High School students expanded the project.
00:05:03.040 --> 00:05:10.160
While building the drifters, students also repaired the mini boat along with two more that were donated to the project.
00:05:10.399 --> 00:05:20.879
They added sensor packs to all three mini boats, not just location, but now heading, pitch, and of course temperature, both air and sea surface.
00:05:21.120 --> 00:05:22.399
Every hour.
00:05:22.720 --> 00:05:27.360
Students are no longer just building tools, they're building data platforms.
00:05:27.680 --> 00:05:31.920
But it didn't go as we thought it would, and that became part of the learning.
00:05:32.240 --> 00:05:35.759
Two of the boats are launched by the Coast Guard on December twenty first.
00:05:36.160 --> 00:05:43.199
The boats travel northeast overnight, heading towards Race Point the next day, but the wind shifts and they loop.
00:05:43.439 --> 00:05:46.560
Just hours later, they land in situate.
00:05:46.720 --> 00:05:52.000
One of them even lands right near the office of Noah Stalwagen Bank National Marine Sanctuary.
00:05:52.399 --> 00:05:55.839
The next morning staff go out and find Riptide right away.
00:05:56.000 --> 00:05:59.279
Then they walk a little further down and find Rockstar.
00:05:59.439 --> 00:06:02.319
Both are recovered before the tide came back in.
00:06:02.800 --> 00:06:10.000
In February, the students present about the project at the Falmouth Education Foundation's Funds and Action Showcase.
00:06:10.240 --> 00:06:17.839
Then in March, a third mini boat was launched by the Coast Guard, the Scarborough Sailor, along with another Falmouth Drifter.
00:06:18.319 --> 00:06:27.279
Overnight, the boat made its way to Plymouth right before the students presented about this very project at the annual Falmouth Steam Fair.
00:06:27.519 --> 00:06:33.920
The tide and waves made it too difficult to recover that afternoon, though, so it spent the night on the seawall.
00:06:34.079 --> 00:06:39.279
And unfortunately by the next day, the boat was heavily damaged and unable to sail again.
00:06:39.439 --> 00:06:43.519
It became a good lesson on what the weather and the ocean can do.
00:06:43.920 --> 00:06:56.879
More drifters are launched in April, May, June, and in the fall of 2023, a new class in Falmouth built more drifters and tested a new design, this one with no sails at all.
00:06:57.120 --> 00:07:00.160
Students also repair the riptide in Rockstar.
00:07:00.720 --> 00:07:07.120
Two mini boats and two mini drifters are deployed by Captain Dave, a fisherman on December 2nd.
00:07:07.360 --> 00:07:09.839
The mini boats head quickly to the northeast.
00:07:09.920 --> 00:07:13.600
The riptide was even spotted at sea a few hours after launch.
00:07:13.759 --> 00:07:17.439
The mini drifters stay behind, much slower than the boats.
00:07:17.680 --> 00:07:22.639
One boat crossed the bay in hours, the other went south and landed on the other side.
00:07:22.879 --> 00:07:28.319
On december fifteenth, they're launched again, this time with two student drifters.
00:07:28.720 --> 00:07:41.519
The boats go northeast again, almost following the same path as the previous launch, even though they were launched in different places, but this time they both land on the other side of the bay by the afternoon.
00:07:42.000 --> 00:07:47.600
As for the drifters, one stayed for weeks, but another didn't stay in the bay very long at all.
00:07:47.839 --> 00:07:48.879
It escaped.
00:07:49.120 --> 00:07:57.839
It traveled out into the open ocean, looping through major ocean currents, riding along the continental shelf, and eventually reaching the Gulf Stream.
00:07:58.079 --> 00:08:01.199
Another successful season, to say the least.
00:08:01.600 --> 00:08:10.079
In the fall of 2024, the fleet was complete, two sails up, one sail down, and two no sails at all.
00:08:10.240 --> 00:08:19.920
They're all launched from the research vessel the Tioga on April 8, 2025 by Captain Pete and the crew from the Woods Hole Oceanographic Institution.
00:08:20.160 --> 00:08:22.639
They were heading out to do some sampling.
00:08:22.959 --> 00:08:26.639
Same launch, different designs, different results.
00:08:26.879 --> 00:08:29.839
The mini boats land to the west just hours later.
00:08:30.000 --> 00:08:38.080
The mini drifters landed next, and the student drifter ended up where a large pot of right whales were sighted a few days later.
00:08:38.320 --> 00:08:39.840
And you learn something new.
00:08:40.159 --> 00:08:42.399
Whale food drifts too.
00:08:42.879 --> 00:08:50.960
With each year of this project, a new group of students took part and added something, a drawing, a layer of epoxy or two.
00:08:51.279 --> 00:08:57.600
Every launch revealed something new, but always to answer the same question, how does the water move?
00:08:57.840 --> 00:09:02.320
When you check the data, you're not just looking at dots, you're noticing patterns.
00:09:02.559 --> 00:09:04.799
The drifters move differently than the boats.
00:09:05.039 --> 00:09:06.799
The weather conditions matter.
00:09:07.039 --> 00:09:14.080
This connects what you learn in the classroom with what's happening out there in the little blue bay and the big blue ocean.
00:09:14.399 --> 00:09:24.639
You start thinking about everything that moves the same way your mini boats and drifters move, the sea turtle, the whale food, an oil spill, a search and rescue team.
00:09:24.879 --> 00:09:34.000
You're watching pathways, and maybe you start to see your own pathway too, because while you're tracking your fleet, you're also seeing the bigger picture.
00:09:34.320 --> 00:09:38.159
You look at the other ones at sea, each is out there for a purpose.
00:09:38.399 --> 00:09:40.399
Sometimes it's for connection.
00:09:40.639 --> 00:10:05.200
Like a mini drifter that was gifted to Falmouth's sister school in Cabo Verde by a group that traveled there in 2024, a small island nation off West Africa, another cape on the other side of the Atlantic, three thousand three hundred nautical miles between them, one formed by glaciers, one by volcanoes, but both connected by people and sea turtles.
00:10:05.519 --> 00:10:12.960
After the visit, a group of senior students there walked down to where the land meets the sea and tossed the drifter into the surf.
00:10:13.200 --> 00:10:14.799
It traveled west.
00:10:15.039 --> 00:10:17.919
Students tracked it together from both capes.
00:10:18.320 --> 00:10:21.039
Over time, it moved toward the Caribbean.
00:10:21.279 --> 00:10:26.799
For exactly one year and two days it drifted all the way to the Bahamas.
00:10:27.600 --> 00:10:40.320
This is science and it's real research that has real impact, because the same currents that carry the mini boats and drifters inside the bay and out are the ones that power our global and local economies.
00:10:40.799 --> 00:10:43.440
Cape to Cape, it all connects.
00:10:43.679 --> 00:10:55.279
And once you know how the water moves, you can search more effectively, rescue faster, improve navigation, and strengthen coastal resilience while also protecting marine life.
00:10:55.600 --> 00:11:02.639
This is what people mean when they talk about the blue economy, and this project is the blue economy in action.
00:11:03.120 --> 00:11:16.159
And none of it happens without people, champions like Jim Manning, Cheryl Milliken, Carmela Majewski, and the many students whose hands have built, repaired, and relaunched all of these tools over the years.
00:11:16.480 --> 00:11:29.440
And the network of support behind every launch, educators, researchers, community partners, every fisherman and volunteer beachwalker, and of course funders like the Falmouth Education Foundation.
00:11:29.679 --> 00:11:37.600
They are in many ways the wind in our sails, powering the work of educational passages and our public schools forward.
00:11:37.919 --> 00:11:40.879
And now it's time to write the next chapter.
00:11:41.120 --> 00:11:53.039
We are looking for your support and sponsorship to help fund the next part of this story, to help another group of students repair these boats and drifters, get them online, and send them back out again.
00:11:53.440 --> 00:11:59.120
But this time we want to send them all together into the big blue ocean.
00:11:59.440 --> 00:12:00.960
What will happen next?
00:12:01.200 --> 00:12:08.559
Well, the truth is that we don't fully know yet, and that's the point, but it's something we can discover together.
00:12:08.799 --> 00:12:12.240
So the question is, do you want to be a part of it?
00:12:14.320 --> 00:12:17.919
