Oceanography- branch of earth science that studies the ocean Topics covered include Organisms that inhabit the ocean Ecosystems present in the ocean Ocean currents, waves, tides Plate tectonics and geology of sea floor Chemical and physical parameters of ocean Environmental issues that affect the ocean

4 branches of marine science Geological oceanography (marine geology)- study of geology of the ocean floor including plate tectonics

Chemical oceanography (marine chemistry)- study of chemistry of the ocean and its chemical interaction with the atmosphere CTD- conductivity, temp, density

Physical oceanography (marine physics)- studies the oceans physical attributes including temp., salinity, mixing, waves, tides, and currents

Biological oceanography (marine biology)- study of plants, animals, and microbes of the oceans and their ecological interactions
