Whales, turtles and seabirds are in critical danger with 8 million tons of plastic dumped into our oceans every year, marine life is swallowing more plastic than ever and it’s killing them fast. Today I am here to discuss the types of marine pollution and how it affects marine life. Sewage is a common pollution, it consists mostly of greywater,...

Although there are already several laws and regulations in place that benefit the global goal, “Life Below Water”, there is still a tremendous desideratum for more to be put into place. For centuries people have regarded the oceans, rivers, lakes, and coasts as an infinite supply of food, a convenient transport route, and an appropriate ground for dumping. These actions...

Bioluminescence is the term used to define the chemical that produces light energy within the body of an organism. For the reaction to take place organism must contain a molecule called luciferin, which then reacts with oxygen to produce light. According to scientists, there are different types of luciferin, and they vary depending on the animal hosting the reaction. Most...

Echinoderms are a phylum of marine organisms. They are generally characterized as invertebrates that have hard, internal calcium based skeletons, a water vascular system, and a five-rayed radial symmetry. Some examples of echinoderms are starfish, sand dollars, sea urchins, sea cucumbers, and brittle stars. The importance of echinoderms goes past the aesthetics that they bring to marine ecosystems. Echinoderms also...

A marine ecosystem is an ecosystem defined by an aquatic environment with higher salinity compared to freshwater ecosystems. These ecosystems are teeming with flora and fauna, providing one of earth’s major food sources. Covering over 70% of the Earth’s surface, marine ecosystems are divided into several broader types of ecosystem, such as estuaries, salt marshes, mangrove forests, coral reefs and...

Our Earth’s oceans contain some of the most valuable resources on the planet, taking up nearly 70 percent of Earth’s surface. Our seas dictate the weather, clean the air, employ millions, and feed even more. As the use of fossil fuels and greenhouse gas emissions began to rise in popularity, the polluting of the Earth’s oceans did as well, leaving...

Plastic is ubiquitous! From water bottles, bags, clothing, straws and coffee cups to toys, DVDs, Styrofoam, plumbing materials, and furniture; inevitably, it is in our everyday lives. The mix of positive and negative aspects makes this material so controversial. It can save human lives; knee and hip joints to plastic heart valves, however, at the same time it can also...

Rhetoric and the art of persuasion are generally associated with spoken language and oratory. However, a visual image can also make a convincing point, and this is particularly applicable to social and environmental advertising. Its efficiency largely depends on the performance of all possible persuasive means, which Aristotle previously divided into logos, pathos, and ethos (Vu 31). Researchers note that...

Did you know that our oceans sustain human and animal life? Oceans will feed a billion, individuals a healthy meal, every day, forever . However, now the oceans are being filled and killed by throwaway plastics. Did you know that the equivalent of one garbage truck of plastic is dumped in the sea every minute. This works out to be...

How is business contributing to the issue? About 33% of the plastic that contaminates our territory and seas are from food coverings. Today almost every aspect of our food coverings has plastic whether the potato chips packet or ice cream cup whether our favourite refreshment beverage or filtered water bottle, whether expresso coffee or carbonated drink not to forget those...

The issues of marine environment have always become a hot topic among the marine people. Ocean, seas, estuaries, coastal, mangrove forest and all other major water bodies environment is considered as marine environment and have their important towards other life. So, whenever problems occur at these environments can be an issue as it will affect the ecosystem in the marine...

What’s the first thing that comes into your mind when you’re told that a species has been identified as immortal? It’s understood that immortality means having the ability to live forever or last forever. Along with that, it’s also perceived that immortality has always thought to be impossible, but not anymore because the jellyfish “Turttiopsis Dohrnii” is now familiarized as...

A marine theme park, sometimes called an aquarium, is where marine animals are kept and open for public viewing for both entertainment and educational purposes. Marine theme parks have grown extremely popular over the years, and according to Gusset (2011), there are more than 700 million visits to aquariums per annum. Thus, it is obvious that the potential of marine...

What is ocean warming? Ocean warming is induced by rising levels of greenhouse gases preventing heat radiated from the Earth's surface from escaping as freely as it once did. The majority of the excess heat in the atmosphere is returned to the ocean. Since the 1970s, the oceans have absorbed over 93 per cent of the excess heat dispersed from...

Ocean mapping consists of different techniques and resolutions of quality all of which have benefits. 100% of the ocean seafloor has been mapped with a horizonal resolution of 1 to 12 kilometres by the Geosat and ERS-1 spacecraft (Smith and Sandwell 1997). However less than 10% of the global ocean has been mapped by sonar technology (NOAA 2018). Although the...

Since the surface of the Earth is far from being even, the distribution of oceans is not quite equal between the two hemispheres. Taking a closer look at the map, one will see that the Southern Hemisphere (206 x 106 km2) has more water resources than the North one (154 x 106 km2) (Distribution of Water and Land Between Parallels...

We live on a blue planet, with oceans and seas covering more than 70 per cent of the Earth’s surface. Oceans feed us, regulate our climate, and generate most of the oxygen we breathe. We can make a long list of how the oceans and marine life are important to us. Oceans cover more than 70 per cent of the...

The underwater environment consists of both biotic and abiotic sounds that closely related to reproduction and survival of marine organisms (Slabbekoorn et al., 2010).Biotic sounds are produced by living, non-human sources such marine mammals, fish and invertebrates, as for odontocetes (toothed whaled, dolphins and porpoises) where the sound generated by high-pressure air being blown over a bone structure called as...

Ocean acidification is the biggest problem facing the planet with impacts so severe it affects almost all aspects of life. From tiny, microscopic phytoplankton, to Australia’s breathtaking Great Barrier Reef, ocean acidification has the power to wipe out great deals of life here on this Pale Blue Dot we call home. Of course, it is no surprise that at the...

Let's talk about the continental shelf, slope, and rise! The continental slope is the seaward edge of the continental rise, which we will talk about later. Now, let's talk about the continental shelf! The continental shelf is a broad, comparatively shallow submarine deck of continental crust setting up the edge of a continental landmass. And lastly of the “continentals’, as...

Oceans are large expanses of water that expand across more of the Earth’s surface than land. In recent decades, a surplus of harmful human activities has adversely affected marine ecosystems by increasing ocean pollution. Ocean pollution is the spread of harmful toxins and debris throughout ocean waters, which negatively affects surrounding ecosystems. Increasing ocean pollution influences the formation of dead...

Plate tectonics is the driving force for most volcanic activities. At plate boundaries, the crust is either created or destroyed. Divergent plate boundaries, create new crust material from the rising of magma. This new crust slowly pushes the old crust until it gets destroyed by subduction. The sinking of this crust also causes volcanic activities above it. On earth, they...

Sharks are a crucial part of the marine ecosystem. They help maintain the balance and health of the ocean. Shark culling has occurred in Australia in both Queensland and NSW as a response to shark attacks, it also appeared in Western Australia. Shark cull is implemented through shark nets and drumlines. Hundreds of sharks are caught each year in each...

Turritopsis dohrnii is a species of jellyfish with significant ability and is part of the class of Hydrozoa. Large bodies of research on the unique survival strategy and cellular mechanisms of this jellyfish concluded in the 1990s that it is able to revert to its immature form when needed, ultimately hitting a 'reset button'. Turritopsis is the only known genus...
