| 00:0-1 | all right . Mhm . Wow . It sure was | |
| 00:11 | cold on our hike today . It was definitely cold | |
| 00:16 | squeaks , but I doubt it was the coldest place | |
| 00:18 | on Earth . I can think of a few places | |
| 00:20 | that are even colder , like Antarctica down there . | |
| 00:25 | It's super cold all the time . Oh , and | |
| 00:29 | that reminds me I haven't had a chance to watch | |
| 00:32 | the video message from my friend Ariel Waldman . She | |
| 00:36 | actually went to Antarctica and sent me a message all | |
| 00:39 | about it . Do you want to watch it with | |
| 00:41 | me ? Squeaks . Awesome . Let's check it out | |
| 00:45 | . Hi , Mr Brown . I'm so excited to | |
| 00:47 | tell you about my trip to Antarctica . It's such | |
| 00:50 | a special place , and not just because the South | |
| 00:52 | Pole is there . It's the coldest , driest and | |
| 00:54 | highest up continent on earth . In fact , most | |
| 00:56 | of it's actually a desert because it gets so little | |
| 00:59 | rain . Now , when you think of a desert | |
| 01:00 | , you probably think of a place that's really hot | |
| 01:02 | and sandy . But scientists actually consider anywhere that super | |
| 01:05 | dry to be a desert . And with Antarctica . | |
| 01:07 | The lack of water is because it's so cold . | |
| 01:10 | In winter , the average temperature is around negative 60 | |
| 01:13 | degrees Celsius , It's why it's covered with snow and | |
| 01:17 | ice year round . You might be wondering why I | |
| 01:19 | wanted to go to such a cold and dry place | |
| 01:22 | . Well , I wanted to check out what lives | |
| 01:24 | there . Sure , there are penguins , but there's | |
| 01:26 | a lot of other life in Antarctica life that most | |
| 01:29 | people don't know about because it's super small . Living | |
| 01:32 | in and below the ice are tons of teeny living | |
| 01:34 | things that we call extremophiles an extreme a file is | |
| 01:37 | a critter that thrives in a really extreme environment , | |
| 01:40 | like one that's really dry or really , really cold | |
| 01:43 | . What's really neat about extremophiles to me is that | |
| 01:45 | they could give us clues to what life might look | |
| 01:48 | like on other worlds , since most of the other | |
| 01:50 | planets we know about also are known to have extreme | |
| 01:53 | environments . So I wanted to see what actually living | |
| 01:56 | below Antarctica's ice and show off these amazing critters to | |
| 01:59 | everyone else . I spent a little while getting really | |
| 02:01 | good at using microscopes and video cameras , plan my | |
| 02:04 | trip and then headed southwards . The nearest airport to | |
| 02:07 | the part of Antarctica that I was going to was | |
| 02:09 | at least a five hour flight away and they don't | |
| 02:12 | exactly have shopping malls in Antarctica , So I needed | |
| 02:15 | to make sure I had everything I needed with me | |
| 02:17 | . I packed lots of warm socks and the type | |
| 02:19 | of clothes that help you stay dry when you sweat | |
| 02:22 | . Because , yeah , even though it's really cold | |
| 02:24 | in Antarctica , you can still work up a sweat | |
| 02:26 | hiking across the ice and snow . There , I | |
| 02:28 | made sure to also bring some moisturizer with me so | |
| 02:30 | that my skin didn't dry out in my first couple | |
| 02:32 | of days there , I got to do some really | |
| 02:34 | cool things , like I got to actually go in | |
| 02:36 | the ocean underneath the ice that surrounds the land . | |
| 02:39 | I didn't go for a swim . Of course , | |
| 02:41 | the water is way too cold there , so I | |
| 02:43 | actually climbed into this metal structure called the OB tube | |
| 02:47 | . When you're inside is kind of like being in | |
| 02:49 | a submarine . You're surrounded by all these windows that | |
| 02:52 | allow you to actually be able to see out and | |
| 02:54 | see what's happening in the water all around you . | |
| 02:56 | Basically , you get to experience the world below the | |
| 02:59 | ice like all the creatures in the water do . | |
| 03:01 | There was so much life wiggling about and I heard | |
| 03:04 | these weird sounds that sounded like they belonged in a | |
| 03:06 | movie . Turns out they were actually the calls of | |
| 03:08 | seals . It was one of the most memorable experiences | |
| 03:12 | of my life . But what I really wanted to | |
| 03:14 | see was what was living in and under the ice | |
| 03:17 | on land . So I hiked out to one of | |
| 03:18 | Antarctica's glaciers to collect samples . Glaciers are these huge | |
| 03:22 | blocks of ice and snow and rocks that don't melt | |
| 03:25 | in the summer , so I was able to collect | |
| 03:27 | chunks of one and bring it back into the lab | |
| 03:29 | to look and see what was inside it . And | |
| 03:31 | there were so many amazing living creatures . One of | |
| 03:34 | my favorites were the tar degrades . These are tiny | |
| 03:36 | animals , also called water bears or moss piglets , | |
| 03:39 | because you can find them anywhere . It's wet , | |
| 03:41 | including in the water trapped by Mosses . They basically | |
| 03:44 | look like tiny little gummy bears with claws . What's | |
| 03:47 | really cool about them , though , is that they're | |
| 03:49 | practically indestructible . They can survive in extreme conditions that | |
| 03:53 | other critters wouldn't be able to like tons of sun | |
| 03:56 | or very little water . I think the thing that | |
| 03:58 | surprised me the most where the diatoms . They're related | |
| 04:01 | to plants , but they're technically algae , so they're | |
| 04:04 | closer to the seaweed that wraps around your favorite sushi | |
| 04:07 | instead of being perhaps your favorite vegetable . And they | |
| 04:10 | live inside these beautiful glass houses that they make for | |
| 04:12 | themselves , and you can find them in water all | |
| 04:15 | over the world . But the ones I found had | |
| 04:17 | really neat shapes . The ones I saw looked like | |
| 04:20 | perfect little triangles . I had never seen diatoms like | |
| 04:23 | that before . And I can't forget about the spiraling | |
| 04:26 | a their type of bacteria , but not the type | |
| 04:28 | of bacteria that makes you sick . They're what's called | |
| 04:30 | cyanobacteria . That's because they often look blue to us | |
| 04:33 | , and scion means blue . They were so cool | |
| 04:36 | because they looked like moving confetti , kind of like | |
| 04:38 | a party underneath the ice . Sadly , I couldn't | |
| 04:41 | stay at this party forever . After five weeks in | |
| 04:43 | Antarctica , I had to pack up and go home | |
| 04:46 | , but I made a fun website with all the | |
| 04:47 | amazing creatures that I found you can check it out | |
| 04:50 | to at life under the ice dot org . I'm | |
| 04:52 | really hoping I can come visit you all at the | |
| 04:54 | fort , sometimes soon . Until then , farewell and | |
| 04:57 | stay warm . Wow , What an amazing adventure . | |
| 05:04 | Me too . Squeaks . It would be awesome to | |
| 05:06 | visit Antarctica someday . You're right . Squeaks . We | |
| 05:11 | don't need to go to Antarctica to find snow and | |
| 05:13 | ice . We trudged through a whole bunch of it | |
| 05:16 | earlier today so we could collect some and see what's | |
| 05:19 | living in it with our microscope squeaks . And I | |
| 05:22 | are going to go look for amazing extremophiles living in | |
| 05:24 | our wintry world . Then we'll probably watch more videos | |
| 05:28 | of aerials . Antarctic trip . You can find the | |
| 05:31 | link to her Antarctica YouTube playlist in the description if | |
| 05:34 | you in a grown up want to check them out | |
| 05:36 | to We hope to see you next time here at | |
| 05:39 | the fort . Yeah . |
