Sylvia Earle first lost her heart to the ocean as a young girl when she discovered the wonders of the Gulf of Mexico in her backyard. As an adult, she dives even deeper. Whether she's designing submersibles, swimming with the whales, or taking deep-water walks, Sylvia Earle has dedicated her life to learning more about what she calls "the blue heart of the planet." Life in the Ocean tells the story of Sylvia's growing passion and how her ocean exploration...

Explore the layers of the ocean! Students will learn about the animals and plants that live in the various zones: the sunlit zone, the twilight zone, the midnight zone, and the abyss zone. Along the way, students will learn about different units of measurement including meters, yards, feet, pounds, and ounces. With vibrant photos, math charts and diagrams, grade-appropriate text, and informational text features to help navigate the text, students...

The vast majority of animals on our planet are the gloriously diverse invertebrates. From microscopic organisms to the crab with a three-meter leg span, marine invertebrates exhibit enormous variety in form and function. They include sessile and mobile organisms, free-living and parasitic. They live at the surface and within the ocean floor sediments.

An introduction to the many living things, from microscopic plants to huge sharks, that live in the ocean and discusses the importance of oceans to life on earth.

Sound travels much better in water than in air. In fact, low-frequency waves, such as those produced by certain whales, can travel through water uninterrupted for hundreds or even thousands of kilometers, allowing the animals to be "in touch" with their group over vast distances. But what happens when human-generated sound gets in the way?

Our high-tech use of the ocean for food, transportation, and energy has far-reaching effects, particularly on certain species. Focusing on issues from noise pollution to microplastics, we can mitigate our impact to provide better futures for ourselves as well as for marine life. The work begins with understanding the extent of our true impacts.

Semi-aquatic marine mammals exhibit behaviors quite different than those who live fully in the water. In the former, an entire female community in one geographic area can come into estrus simultaneously and needs relatively few males to reproduce. In the latter, reproduction appears to be one of the driving forces of whale songs that can be heard over thousands of kilometers.

If you've ever jumped into frigid water, you quickly realize humans are definitely not adapted to life in the sea. What are we missing? In a word, it's blubber. In fact, blubber is such a successful insulator that marine mammals have evolved internal and external means for getting rid of all that heat, possibly even including planetary migrations.

Orphaned at five, nothing held Whidden back from embarking on sea life seven years later. Serving as an apprentice, he quickly proved his worth, and earned himself a mate's position by his early twenties. Graduating to third, second, and first office, he ended his career in command of, and having part-ownership of his own vessel. This memoir, Ocean Life in the Old Sailing Ship Days, records a series of real events, from his childhood impressions of...
