1. 1.1 Defining marine science
What is marine science?
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

2. 4 branches of marine science
Geological oceanography (marine geology)- study of geology of the ocean floor including plate tectonics

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

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

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