Chapter 2 / Lesson 16. xref Throughout the tides, the days, and the years, an estuary is cradled between outreaching headlands and is buttressed on its Adaptations – Designs for Survival From shoreline tidepools to its deep dark bottom, the Hudson River is a wild place. A brief introduction on estuaries 2. An estuary is a partly enclosed body of water where fresh water coming down the rivers meets with salt water from the sea.Estuaries are fascinating places. Because the soil is so rich, lots of different plants grow in estuaries. Consequently, the salinity levels of the water change over the tidal cycle. An estuary is formed. Marine animals aren't the only ones to benefit from the marsh's bounty. In the Hudson estuary, oysters and seahorses live near New York City, where the water is almost as salty as ocean water. Because bottom waters are rich in nutrients derived from decomposing plant and animal remains, this circulation has the effect of pumping nutrients into the estuary and stimulating biological production. The estuary supports lots of fish due to having both the salt water (of the ocean) and the flow of fresh water (from the river). The estuary is a hostile environment for most plants because salt dominates. Every animal on this planet has had to grow and change over the course of millennia to become what it is today. 0 0.
