Scientists use geological records such as rock formations, ice cores, and ocean sediments to measure oxygen isotope ratios. Changes in these ratios over time can provide insights into past oxygen levels. Additionally, the presence of certain fossils and chemical markers in rocks can also indicate past variations in atmospheric oxygen.
What else can I help you with?
Scientists study small pockets of air trapped deep within frozen glaciers. What are scientists trying to understand about the climate of Earth by analyzing these ice samples?
By analyzing ice core samples, scientists can determine past levels of greenhouse gases, temperature changes, and atmospheric conditions. This helps to understand how the Earth's climate has changed over time and can provide valuable insights into current and future climate trends.
Which has more oxygen above or below sea level?
well.logically it just makes sense that since there is less oxygen above sea level (mt Everest roughly 1/3 of the oxygen at sea level) that there would be more oxygen below sea level. note: this is completely hypothetical and has no scientific backing whatsoever
Would you expect to find many organisms living at the bottom of a deep lake?
No, there would likely be fewer organisms at the bottom of a deep lake compared to the surface or shallower areas. This is because light levels decrease, oxygen levels may be lower, and food availability may be limited in deeper waters.
Where is chert formed and under what conditions does it typically occur?
Chert is formed in sedimentary rocks, often in limestone or dolomite. It typically occurs in environments with low oxygen levels, such as deep ocean basins or shallow marine settings.
Is there oxygen underground?
Yes, there can be oxygen underground depending on the conditions. In areas with good air circulation, such as caves or mines, there may be enough oxygen for certain plant and animal life to survive. However, in deep underground environments like certain caves or beneath the Earth's surface, oxygen levels may be very low or nonexistent.
Oxygen levels in the sea decrease with depth. how do deep sea divers get there oxygen?
plants

Why is oxygen less in caves?
Oxygen levels can be lower in caves due to factors such as limited air flow, vegetation, or microbial activity to produce oxygen. In closed-off or deep caves, oxygen may not be replenished as quickly as it is consumed by animals and microbial life, leading to lower oxygen levels.
How deep will future models of Deep Flight take scientists?
Future models of Deep Flight may be able to carry scientists to 11,000 meters below the ocean's surface.
What are the health benefits associated with deep breathing?
Deep breathing can help reduce stress, lower blood pressure, improve lung function, and increase oxygen levels in the body, leading to better overall health and relaxation.
How many scientists have seen the deep ocean through Alvin's windows?
4,502 scientists have seen the deep ocean through Alvin"s windows.

Why is oxygen a survival challenge in the deep ocean?
There is hardly any oxygen available at low depths, thus making oxygen a survival challenge in the deep.
Why is it that humans can't survive in deep water without oxygen tank?
because oxygen is needed for cellular respiration and deep waterdoesnot contain oxygen
How you can increase oxygen level?
To increase oxygen levels in the body, you can engage in deep breathing exercises, spend time in areas with fresh air and good ventilation, get regular exercise to improve lung function, and maintain a healthy lifestyle with a balanced diet and adequate hydration. If oxygen levels are persistently low, consult a healthcare professional for further evaluation and treatment.
What is blood containing little oxygen called?
Blood containing little oxygen is called deoxygenated blood. It is typically darker in color, such as a deep red or purplish hue, due to the lower levels of oxygen present. This type of blood is commonly found in veins, where it has already delivered oxygen to tissues and is returning to the heart to be reoxygenated.
Is there any oxygen in the deep sea?
As there is oxygen in water (H2o o=oxygen) , if there is water there is oxygen, so yes.
