Humans have explored the far reaches of the globe, from the top of Mount Everest to Badwater Basin—a stretch of land 282 feet below sea level. But for most of our time on this planet, the ocean has been a huge mystery. It's only in the last 50 years that scientists have really started studying the ocean floor, with the help of one amazing creation: Alvin the submersible. A deep-sea vessel that can sink miles below the surface with three people inside, Alvin and its crew have uncovered a treasure trove of information in the last fifty years. From tracking down lost hydrogen bombs to exploring underwater volcanoes to capturing footage of storied shipwrecks, there's so much waiting to be discovered beneath the waves! Join award winning journalist Aly Brown as she dives into the wonders of Alvin’s world and see for yourself what lies in the last unexplored place on earth!","forthcoming":false,"isbn13":"9781250816702","publication_date":"20250408","publisher":"Square Fish","slug":"the-last-unexplored-place-on-earth-investigating-the-ocean-floor-with-alvin-the-submersible","subtitle":"","title":"The Last Unexplored Place on Earth: Investigating the Ocean Floor With Alvin the Submersible"},"discovery":{"categories":{"all":[{"bisac_code":"JNF037070","confidence_band":"medium","label":"Oceans, Lakes & Water","score":0.8081,"source":"bisac_hint_model"},{"bisac_code":"JNF003150","confidence_band":"medium","label":"Marine Life","score":0.7915,"source":"bisac_hint_model"},{"bisac_code":"JNF003090","confidence_band":"medium","label":"Fishes","score":0.7881,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"JNF037070","confidence_band":"medium","label":"Oceans, Lakes & Water","score":0.8081,"source":"bisac_hint_model"},{"bisac_code":"JNF003150","confidence_band":"medium","label":"Marine Life","score":0.7915,"source":"bisac_hint_model"},{"bisac_code":"JNF003090","confidence_band":"medium","label":"Fishes","score":0.7881,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"JNF037070","confidence_band":"high","label":"Oceans, Lakes & Water","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF057020","confidence_band":"high","label":"Boats & Ships","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Oceans, Lakes & Water","score":0.8081,"slug":"oceans-lakes-water"},{"label":"Marine Life","score":0.7915,"slug":"marine-life"},{"label":"Fishes","score":0.7881,"slug":"fishes"}],"reader_fit":["Good for readers interested in deep-sea exploration and ocean discoveries"],"related_lists":[],"series":null,"similar_books":[{"authors":["Mary Boone"],"book_id":"9780593904756","cover_image_url":"https://img.bookfrontier.com/9780593904756.jpg?v=6fb0ca78aa4819df","score":0.7663,"title":"Unfathomable: 20 Wild (but True) Stories About the Ocean","url":"https://bookfrontier.com/books/9780593904756"},{"authors":["Lucie Brunellière"],"book_id":"9781419733567","cover_image_url":"https://img.bookfrontier.com/9781419733567.jpg?v=370fb0cab12a0a33","score":0.7534,"title":"Deep in the Ocean","url":"https://bookfrontier.com/books/9781419733567"},{"authors":["Sam Hume"],"book_id":"9780744059823","cover_image_url":"https://img.bookfrontier.com/9780744059823.jpg?v=d4c80512f63759df","score":0.7514,"title":"An Anthology of Aquatic Life","url":"https://bookfrontier.com/books/9780744059823"},{"authors":["Rosie Colosi"],"book_id":"9781426337055","cover_image_url":"https://img.bookfrontier.com/9781426337055.jpg?v=cb7b6b0a85a79793","score":0.7412,"title":"Alien Ocean Animals (national Geographic Kids Readers, Level 3)","url":"https://bookfrontier.com/books/9781426337055"},{"authors":["Loveday Trinick"],"book_id":"9781536223811","cover_image_url":"https://img.bookfrontier.com/9781536223811.jpg?v=f5d92f15cbb405b1","score":0.7371,"title":"Oceanarium","url":"https://bookfrontier.com/books/9781536223811"},{"authors":["Stacy Alaimo"],"book_id":"9781517918736","cover_image_url":"https://img.bookfrontier.com/9781517918736.jpg?v=8992776bb1f82bf2","score":0.7321,"title":"The Abyss Stares Back","url":"https://bookfrontier.com/books/9781517918736"},{"authors":["SJ King"],"book_id":"9780744080384","cover_image_url":"https://img.bookfrontier.com/9780744080384.jpg?v=1f25d6bf5ba7207d","score":0.7299,"title":"The Secret Explorers and the Sunken Treasure","url":"https://bookfrontier.com/books/9780744080384"},{"authors":["Mike Lawrence"],"book_id":"9781250841285","cover_image_url":"https://img.bookfrontier.com/9781250841285.jpg?v=a3aecca1f330c405","score":0.7261,"title":"Science Comics: Deep-sea Creatures","url":"https://bookfrontier.com/books/9781250841285"}],"topics":[{"evidence_refs":["keyword:scientist books for kids"],"label":"Kids","score":1,"slug":"kids"},{"evidence_refs":["keyword:history of science"],"label":"History","score":0.4536,"slug":"history"},{"evidence_refs":["keyword:women scientists"],"label":"Women","score":0.1854,"slug":"women"},{"evidence_refs":["keyword:science books for kids"],"label":"Science","score":0.1776,"slug":"science"},{"evidence_refs":["keyword:exploring nature"],"label":"Nature","score":0.0486,"slug":"nature"}],"what_you_get":["Themes: Ocean-floor exploration, Deep-sea science, Marine discoveries.","Themes: Kids, History, Women.","Reading lane: Oceans, Lakes & Water and Marine Life."]},"llm_signals":{"confidence":0.91,"pacing":"unknown","reader_fit":["Readers interested in deep-sea exploration and ocean discoveries"],"themes":["Ocean-floor exploration","Deep-sea science","Marine discoveries"],"tropes":[]},"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":true,"similarity_seed":true},"stats":{"amazon_ratings_count":6,"goodreads_ratings_count":30,"goodreads_reviews_count":6,"quality_score":0.8545}}
