Sea floor ecosystem.

Around certain hydrothermal vents on the ocean floor there exists ecosystems which are completely independent of the sun. Distribute a copy of the worksheet deep sea ecosystem cards to each student. Explain that you are going to display pictures of six different deep sea ecosystems. They fix energy from toxic compounds such as hydrogen sulphide rather than from sulight sc 9.

Heip peter m. The census explored ocean life from top to bottom pole to pole microbes to whales. Sunlight does not penetrate to the sea floor making these deep dark ecosystems less productive than those along the continental shelf. Ask students to match ecosystem challenge and adaptation descriptions to photos.

Such chemicals have the same temperature as the surrounding water and therefore often remain suspended in water to create brine lakes within the ocean. But despite their name these plains are not uniformly flat. Seafloor systems has 20 years of experience delivering high performance hydrographic survey solutions to the marine industry. Geological survey researchers found the sea floor is eroding in all five places and the reefs cannot keep pace with sea level rise.

Cold seeps are another type of deep sea ecosystem in which chemicals from below the earth s crust leak through cracks and reach the ocean floor. At depths of over 10 000 feet and covering 70 of the ocean floor abyssal plains are the largest habitat on earth.

They also extend outwards from the coast to include offshore systems such as the surface ocean pelagic ocean waters the deep sea oceanic hydrothermal vents and the sea floor. In the first ecosystem wide study of changing sea depths at five large coral reef tracts in florida the caribbean and hawai i u s. Marine ecosystems include nearshore systems such as the salt marshes mudflats seagrass meadows mangroves rocky intertidal systems and coral reefs. In addition to providing hydrographic systems and service seafloor is a leading manufacturer of unmanned surface vessels usvs.

Herman and jack j. Despite this vast size our knowledge of the deep sea is poor relative to other marine ecosystems and future human threats are difficult to predict. Invite a volunteer to read aloud a description of an ecosystem from an ecosystem card.
