NRCC 150 April 24, 2008 Hydrothermal Vents Hydrothermal vents are a tear in the planet’s crust where hot water is issued out. Life has been discovered at in this deep sea, super hot, high pressured environment. Although it seemed impossible to have life without the sun at one point, organisms are able to stay alive and thrive in these outstanding ecosystems. Organisms that live near hydrothermal vents depend on these vents for life because without them, there is no other sunlight or source of energy to live. There are over 300 known species that depend on hydrothermal vents for life. Marine animals that can live there include clams, fish, tubeworms, chemosynthetic bacteria, and anemones. Marine animals that live near these vents, which usually stay active for one to two years, are able to live in complete darkness and are able to withstand that extremely high temperatures and the extremely high water pressure that the hydrothermal vents create. (Office of Naval Research) Surviving at such high depths and under such extraneous circumstances probably seemed impossible to most marine scientists before these vent animals were discovered.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
