Do US Joint Global Ocean Flux Study was aimed at understanding?
The U.S. launched the Joint Global Ocean Flux Study (JGOFS) in the late 1980s to study the ocean carbon cycle. An ambitious goal was set to understand the controls on the concentrations and fluxes of carbon and associated nutrients in the ocean.
Why is it important to study ocean microbes with regard to the biosphere?
Explain why it is important to study ocean microbes with regard to the biosphere. Microbes account for up to 90 percent of the ocean’s biomass and directly control all of the major biological and biogeochemical cycles responsible for balancing the different ecosystems of the biosphere.
Why autonomous underwater explorers AUEs will provide revolutionary new information on ocean processes?
Oceanographers are already very skilled at gathering information about large-scale ocean processes, but small-scale processes have largely been inaccessible. The AUEs will allow scientists to gather information about local and small-scale processes for the first time to study ocean phenomena in greater detail.
Which of the following is a possible application for discoveries made during ocean exploration?
Discoveries made from ocean exploration can be used to teach and inspire young people, expand scientific knowledge, and help with technological advancement.
How have submersibles benefited ocean exploration?
Autonomous underwater explorers will be used to gather large-scale ocean information. How have submersibles benefited ocean exploration? a. They allow exploration of arctic waters.
Why is it important to study ocean microbes?
Marine microbes play many important roles in the Earth system: they influence our climate, are the major primary producers in the ocean, dictate much of the flow of marine energy and nutrients, and provide us with a source of medicines and natural products.
What are the advantages of a piloted submersible vehicle for exploring the ocean and its inhabitants?
Because they can help us to predict the weather as generated by the ocean floor or currents, and therefore we can help to predict the up coming natural disasters and thus save lives.
What are 3 things scientists use to explore the ocean?
Answer. Technologies used to explore outer space and the ocean include submersibles, remotely operated vehicles (ROVs), satellites, rovers, diving/scuba gear, buoys, mega corers, water column samplers, and sonar for mapping.
Why do we not explore the ocean?
“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don’t notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth’s atmosphere, the pressure would decrease to zero.
What is the purpose of submersibles?
Submersibles are underwater robots that are deployed from the ship to the sea, where they record and collect information from the ocean’s water column and seafloor for scientific analysis.
What are submersibles used for?
Submersibles have many uses worldwide, such as oceanography, underwater archaeology, ocean exploration, adventure, equipment maintenance and recovery, and underwater videography.
How many microbes are in seawater?
one billion bacteria
What is a Microbe? Microbes are everywhere, including the ocean. A single liter of seawater has about one billion bacteria and 10 billion viruses.
How does a submersible help scientists study the ocean?
What is a submersible vehicle used to explore a sea bottom called?
A bathyscaphe is a self-propelled vehicle used for deep-sea dives. Bathyscaphes can dive deeper than a person with scuba gear, and even deeper than submarines.
Who was the first person to discover the ocean?
Some milestones include: 1521: Ferdinand Magellan attempts to measure the depth of the Pacific Ocean. He uses a 2,400-foot weighted line, but does not touch bottom. 1818: Sir John Ross catches worms and jellyfish at a depth of approximately 2,000 meters (6,550 feet), offering the first evidence of deep sea life.
Who discovered the ocean?
Explorer Ferdinand Magellan named the Pacific Ocean in the 16th Century. Covering approximately 59 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world’s ocean basins.
For what purpose were submersibles originally designed?
underwater exploration
The first documented submersible was constructed in 1620 by Cornelius Drebbel. It was powered by rowing oars underwater. Though this craft was originally designed for underwater exploration, it did not take long for inventors and makers of war to recognize the military potential of the submersible.
