#Satellite data Maps Sea floor's Hidden Depths While many detailed maps exist of Earth s continents
what lies beneath our planet s waters has remained somewhat of a mystery. So far only 10 percent of the seafloor has been mapped at high resolution leaving researchers pretty eager to know what s going on in that other 90 percent.
Well now researchers at Scripps institution of oceanography at UC San diego are painting in the rest of the picture.
Harnessing never-before-used satellite altimeter data from the European space agency s (ESA) Cryosat-2 and NASA s Jason-1 the scientists have created stunning maps of Earth s entire seafloor bringing to light mountains
and ridges that have never before been charted. The maps give the researchers a new understanding of deep ocean plate tectonics and little-studied ocean basins.
The vibrant images of these underwater landscapes were crafted by measuring gravity at various parts of the ocean.
According to lead researcher David Sandwell both the satellites are tasked with capturing the Earth s gravity field over the oceans.
The satellites orbit the earth and sends out thousands of radar pulses a second Sandwell a#geophysics professor#at Scripps.#
So we use that data to generate a topography of the ocean s surface. That topography highlights subtle variations and bumps in the oceans waters telling a lot about the surface underneath.
For example if the ocean is raised slightly at one point it serves as an indication of a larger object below.
Let s say you have a volcano on the ocean floor that is 2000 meters tall Sandwell explains.
It has associated extra mass with it and it will perturb the gravity field locally. That perturbation is expressed in the sea surface as a bump.
By mapping out all the bumps and indentions in the water the researchers had a pretty good snapshot of the variations in the Earth s crust.
In order to determine how much underwater mass was associated with a surface bump the researchers developed a scientific model using the laws of gravity calibrated by actual measurements taken by survey ships.
These ships which are responsible for mapping the 10 percent of the ocean s floor that s been mapped so far use specialized sonar systems called multibeam echo sounders to acquire detailed depth information of the seafloor.
Sandwell notes that their maps improve upon seafloor images from the 1990s which were created using older satellite imagery.
and fracture zones that had never been seen before they only captured areas of the seafloor that were relatively young
Along with providing the researchers with a better understanding of the waters uncharted depths Sandwell says these maps will be useful tools for the military
#But most significantly Sandwell says it s important for us to know in detail what lies beneath our oceans surfaces.
His dream is for the entire seafloor to be mapped at high resolution. That 10 percent of high resolution that s been mapped#it s about the same resolution of
We know more about these other planets than we know about the sea floor. We need to try to make high resolution maps everywhere.#

#Earth's Water Is Older Than The Sun Since water is one of the vital ingredients for life On earth scientists want to know how it got here.
One theory is that the water in our solar system was created in the chemical afterbirth of the Sun
. If that were the case it would suggest that water might only be common around certain stars that form in certain ways.#
#But a new study published today in Science suggests that at least some of Earth s water actually existed before the Sun was born
--and that it came from interstellar space.##That s certainly something to ponder the next time you drink a glass of water.#
#But the discovery is also cool because it means water --and maybe life#--may be ubiquitous throughout the galaxy.#
#If water in the early Solar system was inherited primarily as ice from interstellar space then it is likely that similar ices
along with the prebiotic organic matter that they contain are abundant in most or all protoplanetary disks around forming stars study author Conel Alexander explained in a press release.#
#The researchers concluded that a significant portion of Earth s water came from interstellar space by looking at the relative abundance of hydrogen and deuterium.#
Earthly water contains some deuterium too but in low quantities--up to 30 times less than interstellar water.
Looking at a water sample s ratio of hydrogen to deuterium can tell you about what conditions were like when the water formed.
and deuterium that scientists observe in Earth s oceans and on comets. Because of that the researchers estimate that anywhere between 7 and 50 percent of Earth s water had to have come from the interstellar medium in
which the solar system was born. And since other solar systems would have formed in the same interstellar medium the findings suggest that the origins of water On earth were not unique

The latest project to take advantage of the benefits of marine drones theâ Robotic Exploration of Ocean Fronts by The british National Oceanographic Centreâ (NOC) is one of largest and most ambitious unmanned
ocean exploration missions to date. At the beginning of October a fleet of seven marine drones were launched from the Isles of Scilly for a three-week journey across the ocean.
The target area for exploration is an area of ocean marking the boundary between Atlantic waters and English channel.
These boundaries are called fronts and they separate water masses of different properties. The targeted fronts off southwest UK provide ideal conditions for abundant plankton growth which in turn can attract large numbers of fish seabirds dolphins and basking sharks.
As well as measuring the temperature of the water and the weather conditions at the ocean surface they can detect the density of plankton in the water listen for clicks
and whistles of dolphins and porpoises and image seabirds using surface cameras. This data will help scientists map the distribution of the fronts and their associated fauna.
It is fitted with surface and subsurface sensors to gather information such as water temperature and the atmospheric conditions above.
The Robotic Exploration of Ocean Frontsâ project is divided into two phases. Phase one sees a fleet of seven marine drones being launched from a beach on the Isles of Scilly to travel up to 300 miles to the shelf edge and back.

The chemicals allow the water to remain liquid at lower temperatures but also help keep it from boiling off in the thin atmosphere of Mars,

#Micromotors Could Help Reduce Ocean Pollution The buildup of carbon dioxide, a major greenhouse gas, is increasingly impacting oceans around the world, making waters more acidic and threatening sea life.
Nanoengineers at the University of California, San diego have made a splash in trying to overcome this obstacle.
Theye developed tiny motors smaller than the width of a human hair that can autonomously travel through oceans to remove CO2 and convert it to a usable solid form.
the micromotors removed up to 90 percent of the carbon dioxide from a solution of deionized water.
In a seawater solution the micromotors removed 88 percent of the carbon dioxide in the same timespan. n the future, we could potentially use these micromotors as part of a water treatment system,
like a water decarbonation plant, said Kevin Kaufmann, an undergraduate researcher and a co-author of the study.
The motors are six-micrometer-long tubes with an outer polymer surface that holds a chemical enzyme carbonic anhydrase designed to speed up the reaction between carbon dioxide and water and form bicarbonate.
generating oxygen bubbles that propel the motors through the water. However, scientists are currently exploring ways to cut back on the two to four percent of hydrogen peroxide used as they focus on alternatives to use water itself to fuel the motors.
Going Blue: Ocean Landscapes Need Protectiononce the moters complete their mission, they can be recovered from the water
and reused for future applications. f the micromotors can use the environment as fuel, they will be more scalable, environmentally friendly and less expensive, Kevin Kaufmann,
