The Ocean Study

biodiversity2Marine scientists are using all kinds of sciences to help them understand and study the ocean world. Learning about marine organisms required biology,  knowing the chemical properties in the ocean involve chemistry and climatology relates to the study of the  climate affecting the water are some examples.   Oceanography covers wide range of topics, from marine organisms to plate tectonics and the geology of the ocean floor.

Both biotic and abiotic factors influence each other.  If one factor in an ecosystem change, perhaps by pollution or natural phenomenon, the whole system can be alter or disrupt.  Health of the oceans are more important than we think.  They cover 71% of the world and  is home for almost all living matters.  The effects of climate changing on ocean animals are more visible everyday.  The increase in average temperature of the atmosphere and the ocean cause from humans’ actions – greenhouse gases – or from the nature itself, such as Earth’s orbit around the Sun, solar activity, and volcanic emissions.image_gallery

One of the most dramatic change in the ocean from climate changing is coral bleaching. Coral reefs can only tolerate a narrow temperature, high temperature water lead to their death. They provide a home for at least 25% of the marine organisms.
However, it is found that Eilat’s corals have better chance of survival than other sites.


Many fish can change sex during their lifetime! Especially rare deep-sea fish, have both male and female sex organs.
