This water — believed to be seven to 12 miles down in the Martian crust — most likely would have seeped from the surface billions of years ago when Mars harbored rivers, lakes and possibly oceans, according to the lead scientist, Vashan Wright of UC...
90% of the ocean is in the midnight zone.It is (47)entirely(entire) dark.The water pressure is extreme and the temperature is near freezing.The living things found here live close (48)to cracks in the Earth's crust (地壳) and rely on the bacteria that live near the crusts for food...
Marine heatwaves are extreme warm water events that can cause devastating impacts on ecosystems and have complex socio-economic ramifications. Surface signals and drivers of marine heatwaves have been extensively investigated based on satellite observations, whereas their vertical structure in the global ...
1b). Finally, wind can increase the short-period noise levels of any surface station. Here, we overcome the aforementioned challenges by the deployment of an ocean-bottom seismometer (OBS) near or under the calving front of Bowdoin Glacier (Fig. 1b–d). This glacier is one of ~242 ...
Huge groups of Arctic and Antarctic animals were also found living in water that is close to or below freezing . Giant squid ,Antarctic cod , and the lion's mane jellyfishare some species that live under solid ice that is 700 meters ( 2 , 296 ft...
scientists have already found ways to build muscle and increase strength through gene therapy.If gene therapy were used now, it would be almost impossible to find out.In the future, genetically-modified athletes might be able to run the 100 metres in 8 seconds or the marathon in under two ...
They found that in areas where there were no sea otters, populations of sea urchins, their natural prey, had exploded. The urchins had then eaten all the sea kelp, a large seaweed, in the area.In contrast, in areas where lots of sea otters lived, the kelp forests were thick and ...
This echogram illustrates the depth, or distance, under water from the sonar’s returned pulses, and shows a pre-spawning gathering of Atlantic herring on the northern edge of Georges Bank. Georges Bank is to the left, with due North to the right. The ocean surface is at the top and ...
(1988) found that barotropic instability is the mechanism that generates the 50-day oscillations from the results of a numerical shallow-water model. Sengupta et al. (2001) concluded that the oceanic internal instabilities of the background current produce the surface zonal current ISV (u ISV) ...
The researchers from the Institute of Oceanology under the Chinese Academy of Sciences found frequent turbulent mixing in the barrier layer by observing the equatorial Pacific Ocean. The observed barrier layer mixing is as strong as in the mixed layer, yielding effective heat transfers across the iso...
