- 3. Pollution The degradation of water quality by any process that changes ambient water temperature. A common cause is the use of water as a coolant by power plants; the returned warmer water lowers dissolved oxygen levels, which can kill aquatic life.
- 7. Pollution The introduction of harmful substances (chemicals, particles, industrial/agricultural waste) or invasive organisms into the ocean.
- 9. A process where a body of water becomes overly enriched with nutrients (usually nitrogen and phosphorus). This triggers excessive algae growth, which eventually dies and decomposes, stripping the water of oxygen and creating
- 10. Strategies, he specific methods, tools, and locations used by fishers to maximize their catch. This includes techniques like trawling (dragging nets), longlining (using thousands of baited hooks), and purse seining.
- 11. Insoluble materials or mixtures used to recover liquids through absorption (soaking up like a sponge) or adsorption (sticking to the surface). In oil spills, these are used to "suck up" the oil from the water.
- 12. The practice of catching fish from a body of water at a rate faster than the species can replenish its population, leading to a depletion of the stock and potential ecosystem collapse.
Down
- 1. Agents A broad category of substances used to treat oil spills. This includes dispersants (which break up oil), gelling agents (which turn oil into a solid or semi-solid for easier removal), and bioremediation agents (which speed up natural breakdown).
- 2. Chemicals used in oil spill response to break the surface tension of the oil, helping it to break into smaller droplets that can be more easily dispersed or degraded by bacteria.
- 4. Temporary floating barriers used to contain an oil spill. They are designed to "corral" the oil on the surface to prevent it from spreading to sensitive shorelines.
- 5. Protected Area, A clearly defined geographic space in the ocean that is managed and protected through legal means to achieve the long-term conservation of nature. It often restricts human activities like fishing or oil drilling.
- 6. Any form of sea life regarded as food by humans, prominently including fish, mollusks (clams, oysters), crustaceans (shrimp, crabs), and even some edible
- 8. Source A single, identifiable source of pollution from which pollutants are discharged, such as a specific pipe, ditch, or factory chimney.
- 10. Water Pollutants Contaminants that enter rivers, lakes, and aquifers. Common examples include pesticides, heavy metals, and pathogens from sewage.
- 12. Spills The release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity (e.g., tanker accidents or drilling rig blowouts).
