Marine Science and Oceanography
What is a scientist?
Someone who uses the processes of science to find answers about how and why things work in the world, in the observable universe.
What are two influences that the ocean make on the earth?
The two influences the ocean has on the earth is the weather and world climate patterns (how warm, cold, wet, or dry it will be.) It also determines where people live on earth.
Name three resources we get from the ocean.
Three resources that we get from the ocean is food, oxygen, and natural resources like oil.
Have humans seen most of the ocean?
What effect can human interactions have on the oceans?
The ocean is constantly changing because of human interactions—pollution, overfishing have caused damage and coral reefs are dying off & more.
Why does it benefit you to understand the marine environment?
It can change your choices because you know that they can have a consequence.
What is marine science?
Marine Science is the process of discovering the facts, processes, and unifying principles that explain the nature of the oceans their associated life forms.
What is oceanography?
Oceanography is the science of recording and describing the ocean’s contents and processes.
What are the four branches of oceanography?
– Biological oceanography—studies life in the ocean
– Chemical oceanography—studies chemistry of seawater
– Geological oceanography—studies the geology of the ocean
– Physical oceanography—studies the physics within the marine environment
What has made the exploration of the oceans possible?
What traditional science disciplines does marine science draw on?
– Physical Science – study of matter and energy and their interactions
– Life science—study of living things and their interactions with their environment
– Earth and space science—study of the physical earth, the solar system, the universe, and their interrelationships
Why do most marine scientists have training in traditional disciplines?
They draw on research from all three of the traditional sciences.
Beyond traditional science disciplines, what four study areas does marine science involve?
– Science of inquiry—apply science as a way of solving problems, answering questions.
– Science and technology—learning how science advances technology and vice-versa.
Science in personal and social perspectives – how science affects you and society.
Historical nature of science—understanding how science evolved as a discipline.
Why is the concept of situatedness important to marine scientist?
They may establish scientific concepts that they will never personally demonstrate or observe.
What disciplines apply basic marine science?
Sciences, professions, and careers
In what cross-discipline areas do marine scientists need education?
Math, history, technology, social sciences, literature, arts
What is science?
Science is a body of knowledge and an organized method used to gain knowledge about the observable universe.
What is technology?
A material system that produces intended results or in a general sense, knowledge of those systems.
What effects have science and technology had on humans and other organisms?
It has benefited life by health care, transportation, communication, agriculture, and exploration. It has burdened life by things such as oil spills, and global warming.
What three broad actions can society take with respect to the effects of science and technology of the Earth’s environment? Which is the most logical?
1. Consider the environment a lost cause and disregard the effects
2. Dismiss the effect as overstated by scientists and in consequential
3. Prioritize the consequences in developing and applying technologies
The last broad action is the most logical.
When do you apply scientific process skills?
When you apply the scientific method.
What are the five basic steps to the scientific method?
1. Identify the problem
2. Make a hypothesis
3. Test hypothesis
4. Analyze results
5. Report results + conclusion
What is a hypothesis?
An educated guess that you can test about the answer
How do inductive and deductive reasoning apply to forming a hypothesis?
Inductive is what you see, deductive is what you would see
What is a theory?
When the data supports your hypothesis
Why is reporting results crucial to the scientific process?
It allows other scientists of verify your work
How does science progress?
Through a revision of theories in the light of new evidence or better explanations of existing evidence
How does it benefit you to stay up to date with current trends, findings, and developments in science and technology?
1. You can anticipate changes
2. By being current, you can help society handle the effects of science
3. You can base your ethical evaluations, estimates, and other potential effects on current information
