Epipelagic Zone

The upper zone, also known as the high tide zone, does not have enough water to sustain large amounts of vegetation.[8] The predominant organisms are anemones, barnacles, hermit crabs and limpets. The rock pools in this area are inhabited by large seaweed and small fish.

9. Oceanward of the oceanic trench, the ocean bottom first rises and then levels off to a depth of approximately 3900 m, making the deepest part of the ocean trench about [(1400)(2400)(3500)] m below the bottom of the abyssal plain ocean bottom west of the trench.

The Tidal zones consist of splash zone, high water neap tide, low water neap tide, high water spring tide, low water spring tide, mid tide level and the splash zone and sub littoral zone. All of these tidal zones can be determined by which indicator organisms/animals are living there. For an example the splash zone is the highest of all zones and the organisms that are generally living there are noddiwinkles. If you spot a lot of honeycomb barnacles and blue-grey periwinkle’s then you are most likely in the high water tide zone and water only covers this zone at high tide. White tube worms are indictor organism the mid tide level zone and is covered by water for half of the day. There’s also the low tide zone which is engulfed in water for the majority of the day expect at low tide, you can determine this zone by finding indicator organisms such as sea squirts. The final tidal zone is the sub literal zone and this is always under water the indictor organism’s living here are brown tubeworms and striped girdled chiton.

Have you ever seen Finding Dory and wondered about all those creatures living under the sea? The ocean is the largest out of all of the ecosystems it is a stretch of sea which is divided geographically into four sections called the Atlantic, Indian, Antarctic, and Arctic Ocean the elements found in the ocean is H2O which makes water and NaCl making sodium chloride but there are main chemicals in sea salt as well such as sulfate magnesium potassium and calcium the ocean gets its saltiness because of when it rains on land the rain water dissolves the minerals from the rock then that rainwater flows into rivers and then to the sea when the water undergoes evaporation it leaves the minerals hence why the ocean is salty. In different parts of

They move into deeper water during the colder months. Depths about 32 to 262 ft, and in the warmer months they can be found 10 to 25m underwater. The biogeographic regions are in the Atlantic ocean(native) and Pacific ocean(native). The Aquatic

An entire new world, different from our own exists beneath the surface of our oceans. This life is full of color, shapes, sizes, wonder, and even darkness. Much of this life has yet to be explored but we still know that beneath the waves exist the most beautiful creatures and the most bizarre. Magical areas such as the coral reef and mysterious areas such as the depths of the ocean are homes to over 700,000 species that live in the ocean. This includes the eighty percent of the ocean that has yet to be explored. Even though there may be separate oceans on this planet, they are still interconnected by a body of salt water. No area of the ocean is the same, which brings us to the wonderful fact that so many different species are able to flourish

In ocean studies, the neritic zone, also called coastal waters, the coastal ocean or the sublittoral zone, refers to that zone of the ocean where sunlight reaches the ocean floor, that is, where the water is never so deep as to take it out of the photic zone.

The difference between the littoral zone and the profundal zone is that the profundal zone does not have light that reaches it and it is under the limnetic zone, but both have a bottom sediment benthic zone where decomposition is common.

2. What are the three major layers (zones) found in the ocean? Describe each layer briefly. The three layers of the ocean are the surface layer, the thermocline, and the deep zone. The

If we are in deep waters we stay near the surface. We live in warm tropical waters in the Atlantic, Indian, and Pacific oceans. We mostly eat sponges, anemones, squid, shrimp, and of course, jellyfish!

There are many different creatures in the ocean. They are categorized into 3 different groups that are Zooplankton, Nekton, and Benthos. In the ocean the zooplankton eat phytoplanktons. Zooplankton are eaten by all of the larger animals. Phytoplankton self reproduce so they don’t need to eat other things. They create their own food. The Nekton eat the zooplankton because it is a smaller species than the rest.

Deep ocean trenches are environments that have historically been shrouded in mystery, their inaccessibility rendering such limited explorations as net dragging and dredging for samples (Lee, 2012). While potential for chemosynthesis had been proposed as long ago as 1890, it was nearly a century later before such systems were demonstrated to be active on the ocean floor (German, 2011). Further investigation has shown that ecosystems are surviving and thriving along the ocean floor within these trenches. Studies have shown that deep ocean trenches contain ecosystems that are biologically and geologically active, producing a high diversity of organisms that must withstand a variety of environmental changes (Anderson et al., 2014). Recent explorations have confirmed new forms of life in deep ocean trenches. Life discovered in such an extreme environment is call for investigation.

Life in the Hadal Zone is quite intriguing. In the Hadal Zone, which at 11,000m is deeper than Mount Everest is high, the pressure rises to about one ton per square centimeter. There is almost no light at all, plants cannot grow, and there is very little food. Somehow, the ocean, and the sea life in it, still has the ability to manage a diverse environment of fish. "There are more species of animals in the deep sea than beetles in the rainforest," says Dr Copley, a deep-sea biologist from Southampton National Oceanography Centre.

Scientists learned Agricultural Fertilizers to be the reason for the Dead Zone however now the focus is on trying to shrink the zone. Dave Whithall claims the dead Zone forms each April and lasts through summer at its highest point in July. In July water can span from 5,000 to 8,000 square miles which is 13,000 to 21,000 square kilometers almost the size of New Jersey. Nutrients allow Phytoplankton’s called Algae to bloom. When they die they sink to the bottom and are eaten by

The intertidal zone is a severe environment that has various stressors and forces which act on organisms that are not found in strictly marine or terrestrial environments. This environment is unique due to the constant fluctuating water levels which exposes organisms to air and the forces of crashing surf that only animals and plants with special adaptations are able to withstand. Despite all of these environmental conditions, these species are able to survive and reproduce within extreme environments.
