345P: YA book where kids get gills cut in their necks and go underwater

A group of kids, maybe a girl and her younger siblings, are surviving on their own. They meet a boy on the beach, who cuts gills into their necks somehow, and they go swim in the ocean and visit a deep and dangerous chasm at one point. Mermaids may or may not be involved. They leave the water in the end. The cover is blue with a picture of them swimming; the art wraps around the front and back, though it was probably a paperback. YA Pre-2000. Eerie feel.

342Q: Vintage Picture Book Featuring the Ocean

Vintage Picture Book (from 50s, 60’s, or 70s), not very thick, stapled, maybe 10 – 12 pages, not a lot of printed text. Watercolor, realistic illustrations

What I remember about the story: A boy spends a lot of time snorkeling, he sees all kinds of fish and turtles, and he finds a shipwreck and a shark shows up (scary) but he escapes and finds a treasure.

I remember the following illustrations:

  1. Sea stars on a sandy ocean floor, the sunlight is shining through the water onto the ocean floor
  2. A sea turtle swims and again the sunlight coming through the water
  3. A two page illustration showing the boy on the left top looking down on the shipwreck, again the light plays through the water

The illustrations were realistic and what stood out was the light portrayed underwater.

 

322G: Ocean Adventures in Octopus Town (Solved)

I want to help my wife find a book that her mom used to read to her. Mom says it was a paperback picture book and the pages had metallic highlights so they sparkled. The cover had the main character on it, a young girl who had long brown hair and eyeglasses and she was surrounded by seaweed.
In the story/poem the girl falls into the ocean and encounters a variety of sea creatures as a result.
Some lines and plot points from my wife and mother-in-law’s memories:
“…and arm in arm we danced way down, until we reached octopus town. And there we saw one hundred more, eight hundred legs, one hundred heads, dancing in their seaweed beds”.
A line toward the end of the story describes something involving a dense school of sardines or mackerel as “bits of silver hit like hail”
In the end, the main character is being chased by a shark and wakes up, falling out of her bed.
Thank you so much!

291X: A voyage aboard a research vessel

The book I am looking for is about the oceans. I read in in the late 1970s. It was written by a man who was participating in an ocean voyage aboard a research vessel. I think he may have been a Canadian, and the book may have been published via McGill University. He described the oceans as having four levels, each level’s current went counter to the level above or below it.

Thanks and good luck. I would love to read this book again.
