Marine debris‚ commonly known as marine litter‚ is man-made waste that is deliberately or accidently released into oceans‚ lakes‚ seas or any other type of waterway. 6.4 million Tonnes of garbage are found in the world’s oceans every year and it just keeps increasing. 90% of this garbage is found to be plastic. Marine debris comes in many different forms. One form is ghost nets‚ these are fishing nets that fish and other creatures get caught in. The ghost nets restrict movement which means that

As we know leading Marines is the most important part of the Marine Corp. There are eleven leadership principles‚ and fourteen leadership traits a great leader demonstrates.

The name comes from the Greek words φυτόν (phyton)‚ meaning "plant"‚ and πλαγκτός (planktos)‚ meaning "wanderer" or "drifter".[1] Most phytoplankton are too small to be individually seen with the unaided eye. However‚ when present in high enough numbers‚ they may appear as a green discoloration

Marine Biology is the scientific study of organisms that are dependent on water. Marine Biology is an interesting topic to many people because of the exotic animals you get to work with. A career in Marine Biology can be dangerous because of the wild animals‚ but at the same time it can be fun. It takes time‚ training‚ and intelligence to succeed in the career. In order to make it in this Biology field you must complete a college work in oceanography‚ marine biology‚ or conservation. You will

Marine Ecosystems are the largest systems on the planet‚ covering over 70 percent of the Earth’s surface and constituting over 99 percent of the living space on the planet (area x depth). These vast ecosystems are composed of many different habitats which extend from the near shore regions to continental shelves and the deep ocean. They are home to millions of species and provide food‚ income‚ protection‚ and many other vital ecosystem services to billions of people around the world. ECOLOGICAL

Research Paper The ocean is one of‚ if not‚ the largest biome on earth. There are more than one million species of marine life. Covering over 70 percent of the Earth’s surface‚ the ocean is our planet’s largest habitat‚ containing 99 percent of the living space on the planet. This area holds the life of nearly 50 percent of all species on Earth. Like lakes‚ oceans are subdivided into separate zones: intertidal‚ pelagic‚ abyssal‚ and benthic. All four zones have a great diversity of species. The

We know very little about the effect that pollution has on the oceans‚ but we continue to dispose off chemicals‚ sewage and garbage into it at an unprecedented rate. Most people likely do not even know what types of pollutants reach the oceans. There may be billions of people unconcerned about ocean pollution and hence this

The major biomes are the tundra‚ taiga‚ tropical rain forest‚ temperate forests‚ desert‚ grassland‚ savanna‚ chaparral‚ and marine. Each biome has it’s own characteristics such as the tundra. The tundra is a biome that is located in the Northern Hemisphere of the world. It circles the North Pole and reaches down to the taiga. The tundra has a very cold and harsh climate‚ especially

activity in the entire world is having a very serious effect on the health of the oceans as a whole. When commercially valuable species are overexploited‚ other species and habitat that share the same ecosystem are affected. According to many marine scientists and marine ecologists‚ unsustainable (overfishing) fishing is the greatest threat to the ocean ecosystems. For example‚ recent scientific studies suggest that overfishing of large shark species has had a ripple effect in the shark’s food chain‚ increasing
