Intro
a science that deals with the oceans and includes their extent and depth, the physics and chemistry of their waters, marine biology, and the use of their resources
oceanography
catching too many fish at once, so the breeding population becomes too depleted to recover
overfishing
What is the Great Pacific Garbage Patch/Trash Island?
the largest accumulation of ocean plastic in the world, located in the northern Pacific Ocean
Why shouldn't you eat a lot of tuna?
Mercury pollution
Why are some penguins dying in Antarctica?
Melting sea ice
2 reasons to study oceanography
Food, transportation, minerals/oil, lots of people live there
extremely small pieces of plastic debris in the environment resulting from the disposal and breakdown of consumer products and industrial waste
microplastics
the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution
oil spill
Why do coastlines flood more now than they used to?
Rising sea level
Why are the polar bears dying off?
Melting sea ice/loss of habitat
the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
weather
the decrease in the pH value of the Earth's oceans, caused by the uptake of carbon dioxide from the atmosphere
ocean acidification
includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns
climate change
The big hurricane that recently hit New York City and caused massive flooding
Why are seals in the Artic dying?
Melting sea ice
the weather conditions prevailing in an area in general or over a long period
climate
an area of an ocean that has too little oxygen to support life
dead zones
aquaculture
fish farming in the ocean
How do pollutants created on land affect the ocean?
Runoff -- pollutants drain into rivers, which drain into oceans
Why are the coral reefs dying?
Ocean acidification
