Explain why autonomous underwater explorers (AUEs)
will provide entirely new kinds of information about ocean processes
. 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.
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?
It is crucial to study ocean microbes
because THEY CONTROL THE MAJOR BIOGEOCHEMICAL CYCLES THAT KEEP EARTH’S BIOSPHERE IN BALANCE
. The ocean is made up of many microbes, which play important role in the process of biogeochemical cycling of various elements.
What is the most abundant source of methane in the Globe?
In addition to the human sources, methane is also produced in natural settings. The greatest natural source of methane is
wetlands
, which contribute 30% of global methane emissions. Other natural sources of methane emissions include the oceans, termites, permafrost, vegetation and wildfires.
Which of the following goals is the US Integrated ocean Observing?
The goals of an Integrated Ocean Observing System (IOOS) aim to:
Improve the safety and efficiency of marine operations
. More effectively mitigate the effects of natural hazards. Improve predictions of climate change and its effects on coastal populations.
Which of the following best explains the role of deep sea coral reefs in the environment quizlet?
Deep sea corals can be hundreds or thousands of years old. Which of the following best explains the role of deep sea coral reefs in the environment?
a. They are responsible for fouling fishing lines.
Why will Autonomous Underwater Explorers AUEs will provide revolutionary new information on ocean processes?
Explain why autonomous underwater explorers (AUEs) will provide entirely new kinds of information about ocean processes. … 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
.
How can microbes play a biological role in the ocean?
A bacteria colony on the ocean floor illustrates the ubiquitous nature of microorganisms. Marine bacteria play a major role
in the ocean’s nutrient cycles
. sewage into the oceans releases huge numbers of bacteria and viruses into the water. … The water that is contaminated by these microbes can be the source of diseases.
Does sea water contain microbes?
Microbes are everywhere
, including the ocean. A single liter of seawater has about one billion bacteria and 10 billion viruses.
What does bacteria do in the ocean?
Bacteria are
the scavengers of the ocean
: they assimilate half of the organic carbon that comes from waste material in the food chain (from phytoplankton to fish). This gives them a key role in the global carbon balance because they’re the only organisms in the sea capable of transforming this kind of waste.
What is the biggest emitter of methane?
The largest source of anthropogenic methane emissions is
agriculture
, responsible for around a quarter of the total, closely followed by the energy sector, which includes emissions from coal, oil, natural gas and biofuels.
What are two natural sources of methane?
Natural sources of methane include
wetlands, gas hydrates, termites, oceans, freshwater bodies
and other sources such as wildfires.
What produces the most methane on Earth?
Plant agriculture, including both food and biomass production, constitutes a fourth group (15%), with
rice production
being the largest single contributor. The world’s wetlands contribute about three-quarters (75%) of the enduring natural sources of methane.
Why are coral reefs overexploited?
a. Why are coral reefs overexploited? …
Coral and its organisms are valuable commodities in the aquarium industry
.
What are some reasons for exploring the mid Cayman Ridge?
What are some reasons for exploring the mid Cayman Ridge? Answer:
Since life on Earth predates photosynthesis
, the exploration of this deep-water environment that lacks any source of light could provide information on what those life forms looked like.
What best explains the role of deep sea coral reefs in the environment?
Coral bleaching occurs when a colony of polyps are under stress. Which of the following best explains the role of deep sea coral reefs in the environment? a.
They are responsible for fouling fishing lines.
