What is charts, nautical? definition and meaning

Maps that have been specifically designed to meet the requirements of marine navigation are called nautical charts. These graphical portrayals of the marine environment depict elevations of selected topographic features, general configurations and characteristics of the coast, water depths obtained from hydrographic surveys, the nature or composition of the bottom from grab samplers, dangers and [...]

What is chemical oceanographers? definition and meaning

Chemical oceanogra-phers are scientists who study the chemistry of the sea to include the sediments below and the atmosphere above and their interrelationships. They investigate chemical processes, track the movement of chemicals in the ocean, and identify the effects of contaminants on marine ecosystems.

What is Chesapeake Bay? definition and meaning

Chesapeake Bay is a semi-enclosed body of water partially protected from the open sea, which is located in the mid-Atlantic along the U.S. East Coast. Marine scientists classify Chesapeake Bay as a drowned river valley estuary. It is the largest estuary in the United States, spanning nearly 200 miles (321.9 km) from the Susquehanna River [...]

What is Chesapeake Bay Observing System? definition and meaning

In 1989, the University of Maryland Center for Environmental Science, Horn Point Laboratory, launched the Chesapeake Bay Observing System (CBOS) with two realtime instrumented buoys placed in the upper and middle reaches of the bay. Like the tides, the number of CBOS stations has increased and decreased based on user requirements and funding. The system [...]

What is Chondrichthyes? definition and meaning

Sharks, skates, rays, and chimeras all belong to the class of living fishes called chon-drichthyes. Chondrichthyes comes from the Greek chondros for cartilage and ichthys for fish. What these fishes all have in common is the possession of a skeleton composed of cartilage rather than true bone. There are other differences as well, but this [...]

What is catadromous stocks? definition and meaning

Supplies of wild fish species that spend most of the life cycle in freshwater but migrate to salt water to breed are catadromous stocks. Freshwater eels (Anguillidae) are one of the most common families of catadromous fish. Anadromous fish, such as salmon and lamprey, live the majority of the life cycle in salt water and [...]

What is causeway? definition and meaning

A causeway is usually an unimproved road or a paved road constructed across marshy or periodically flooded terrain. Natural causeways may form when lava floes from volcanic eruptions near the coast comes into contact with the ocean whereas man-made causeways may also be fairly elaborate roads that cross broad water bodies or wetlands. During medieval [...]

What is cephalopods? definition and meaning

Squids, cuttlefishes, octopi, and nautili constitute a class of animals known as the cepha-lopods. The cephalopods, or head-footed animals as they are called (cephalo from Latin meaning head, and poda meaning foot ), are placed in the phylum Mollusca (soft-bodied animals), and are characterized by having a linearly chambered shell, which in some species has [...]
