Environment Sea

In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water. This healthy seagrass baffled marine biologist Brent Hughes. The scientist expected this estuary to be overrun with algae, causing the seagrass to die. Why was the seagrass thriving? As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain?

This is a fascinating book filled with stories about shipwrecks and various disasters at sea, retold in an easy to comprehend and story-like fashion.

On October 29, 1991, the 70-foot longliner Andrea Gail, on day 40 of an extended commercial swordfishing trip, was lost in a convergence of three powerful storms off Canada’s Grand Banks. Data buoys measured waves as high as 100 feet, and the boat was hit with winds measuring 80 knots (92 miles per hour). The Andrea Gail’s emergency beacon washed ashore that November on Sable Island, off the coast of Nova Scotia, but the boat and 6-man crew were never found. The crew left behind five children among them, and the entire small town mourned the loss.

Rising sea level is the most profound long-term aspect of climate change. Yet, the public is almost completely unaware of the magnitude of the problem. For three million years sea level regularly moved up and down almost 400 feet with the ice age cycles. Now, after 6,000 years of minimal change, we are entering a new era of rapid sea level rise. In clear, easy-to-understand language, this book explains how, why, and what will happen.

There is a village that sits at the edge of lush rainforest, its stilted huts face the ocean, its children plunge below the water's surface with spears to learn the ways of their elders. This is the Surin Islands, on Thailand's Andaman coast, and home to the Moken, the world's last sea nomads. For centuries, the Moken roamed Burma's Mergui archipelago, diving for shellfish to trade for rice, taking shelter on land only during the monsoon season.

You might know that green sea turtles have incredible shells, but there’s so much more to learn about these underwater marvels! Find out how green sea turtles keep seagrass beds healthy by “mowing” them, and how some species of fish like to hitch a ride on their shells. You’ll also witness the amazing egg hatching frenzy that occurs—when baby turtles have to make a mad dash from the beach to the safety of the sea. Filled with simple science and plenty of animal facts, this book also looks at the conservation challenges these endangered animals face.

There are more than 200,000 known species in the ocean, but there is thought to be more than two million more that remain undiscovered. Humans have only explored five percent of Earth’s oceans, so what else could be lurking deep beneath the surface? In this bite-sized, curated collection, Seeker dives in to explore the deepest parts of the oceans, how they get polluted, and how scientists discovered a hidden ocean in the most unusual place.

Follow a hatchling's treacherous journey from nest to sea. Longtime science writer Stephen Swinburne creates an engaging first-person narrative from the sea turtle's perspective.

Slurp! A boy finishes his drink and tosses it in the trash, straw and all. He moves on without another thought. In the waters off of Costa Rica, scientists spot an endangered sea turtle and pull him aboard to study him. But he has something stuck in his nose. A barnacle? A stick? No...it's a plastic straw! This heroic story of one turtle's rescue reminds us that even the smallest straw can hurt our ocean life—and that the smallest demand for change can grow into something big!
