Navy

There are many careers in the navy. One of them is a Nuclear Technician. Nuclear Technicians are the people who work in submarines and aircraft carriers that keep the nuclear power working and stable. The thing I found most interesting about the navy is the many places it allows you to travel to during your enlistment.The presentation affected my understanding of the ocean by showing me how important it is to keep our waters safe because most of our trade is through the ocean. The thing I will always remember about this presentation is the fact that the navy's science programs greatly affected how we study and understand the ocean.

Whales

Flukes are used to ID whales because each fluke is different, like a person's fingerprint.
Scientists need this data because it helps them track how  and where whales travel through the ocean.
The most difficult part of the whale fluke lab was finding matching marks on the flukes. A change you could make to this lab to make it better would be to let us match more than four whale flukes.

Overfishing

Over fishing is a major concern because it rapidly depletes the population of fish in the ocean.Over fishing affects my daily life because it puts a strain on the ecosystems in which the fish belong by making the predators that hunt the fish struggle to find a food source. Choices you can make to help stop over fishing is to eat fish that are not caught by over fishing and to write to congress and ask to make over fishing laws.

Coral Bleaching

 Coral Bleaching is the bleaching of coral by the dying of a corals zooxanthellae. The dying of zooxanthellae can be caused by overfishing and increased water temperature. Coral Bleaching affects organisms living in the coral reef by reducing the availability of zooxanthellae to its inhabitants, causing a decline in the population of everything that lives in the ecosystem.

4 Problems Caused By Marine Debris

6 Pack Rings- can catch animals, killing them or horribly disfigure them.

Plastic Bags- look like jellyfish and are eaten by animals. Ingesting plastic bags poisons the animals and can suffocate them.

Oil- Coats animals, making them unable to feed and breath effectively

Bottle Caps- Bottle caps are eaten by birds because they mistake them for food. Since the plastic is hard to digest, the bottle caps stay in the stomach, leaving less space for normal food.

To help reduce problems caused by marine debris, we can reduce, reuse and recycle our plastics.

Little Stinger of the Sea

Common Name: Lion Fish
Scientific Name:Pterois
Adaptations: Have poisonous spines used for defense against predators
Hunting Strategies: They do not use their spines for hunting, only for defense. They hunt just like any other fish.
Reproduction:Females release two mucus-filled egg clusters frequently, which can contain as many as 15,000 eggs.
Interesting facts: Bigger Lion Fish may be cannibalistic
Why I chose it: I chose the Lion Fish because it looks cool

Sea Grass

Sea grass provides food for many organisms in the through its detritus and leaves. Residents of sea grass ecosystems live in the sea grass while migrants and travelers only visit sea grass ecosystems occasionally.
