Sea Floor Ecosystem

Marine ecosystems include nearshore systems such as the salt marshes mudflats seagrass meadows mangroves rocky intertidal systems and coral reefs.

Sea floor ecosystem.

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. Seafloor systems has 20 years of experience delivering high performance hydrographic survey solutions to the marine industry. Explain that you are going to display pictures of six different deep sea ecosystems. 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.

Geological survey researchers found the sea floor is eroding in all five places and the reefs cannot keep pace with sea level rise. The importance of organic matter priming paul van nugteren leon moodley geert jan brummer carlo h. Hawaii was formed by huge underwater volcanoes located on the ocean floor. Sunlight does not penetrate to the sea floor making these deep dark ecosystems less productive than those along the continental shelf.

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. Project results continue to play a critical role in deciding how to manage this valuable global resource. They fix energy from toxic compounds such as hydrogen sulphide rather than from sulight sc 9.

At depths of over 10 000 feet and covering 70 of the ocean floor abyssal plains are the largest habitat on earth. Herman and jack j. 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. Such chemicals have the same temperature as the surrounding water and therefore often remain suspended in water to create brine lakes within the ocean.

The deep sea floor ecosystem is one of the largest on the planet covering roughly 60 of the earth s solid surface. Invite a volunteer to read aloud a description of an ecosystem from an ecosystem card. But despite their name these plains are not uniformly flat. Heip peter m.

Distribute a copy of the worksheet deep sea ecosystem cards to each student. Ask students to match ecosystem challenge and adaptation descriptions to photos. In addition to providing hydrographic systems and service seafloor is a leading manufacturer of unmanned surface vessels usvs.
