The Study of Oceanography
What is oceanography?
5 areas of science:
1. Marine geology
2. Physical oceanography
3. Chemical oceanography
4. Marine engineering
5. Marine Biology
The study of the composition of the inner earth, sea floor sediments, the history of the ocean, continent movement, climates, earthquakes, resource distribution, and where resources come from
The study of waves/wave dynamics, currents, tides, atmospheric interactions
The study of what gases and solids are dissolved in the water, how they are dispersed, and their relationships to the geology and biology of the ocean as a whole
The study of the structures (oil platforms, ships, harbors) that help us use the ocean wisely
The study of life, nature, and distribution of marine organisms, the impact of oceanic and atmospheric pollutants on the organisms, the isolation of disease-fighting drugs from marine species, and the yields of fisheries.
The recording and description of the characteristics of the ocean. This term inadequately describes modern scientific ocean investigations
The scientific study of the sea by applying traditional science, such as physics, chemistry, mathematics, etc. to all aspects of the ocean
How to study the ocean
The Scientific Method
4 Steps of The Scientific Methods
1. Question something observed in nuture
2. Working hypothesis
4. Form theories or laws
A well-tested hypothesis that has not been disproven
Tells you what usually happens in nature; a summary of what happens in nature
The systematic process of asking questions about the observable world by gathering and then studying information (data), but the information itself is not science
The Scientific Method
The process oceanologists use to obtain and interpret data.
What is the first step in the Scientific Method?
Ask a question about something observed in nature
What is the second step in the Scientific Method?
Form a working hypothesis to explain that observation
What is the third step in the Scientific Method?
Conduct an experiment, and/or make additional observations to test the hypothesis
(try to prove the hypothesis correct or incorrect)
What is the forth step in the Scientific Method?
Form theories and laws
(General explanations of observations about nature)
Why study the Scientific Method?
Because it will be on the test! Also, scientists use it to understand the OBSERVABLE world.
Can I use the Scientific Method to understand the natural world that I can’t test with experiments or observations?
No! You must be able to do experiments or make observations to use the Scientific Method.
