#Earth s wobble fixes food for ocean creatures Princeton university rightoriginal Studyposted by Catherine Zandonella-Princeton on September 16 2013the cyclic wobble of the Earth on its axis controls the production of ixednitrogen

which is essential to the health of the ocean according to a new study. The findings published in Nature give researchers insight into how the ocean regulates its own life-support system

which in turn affects the Earth s climate and the size of marine fisheries. Researchers report that during the past 160000 years nitrogen fixation rose

The finding that nitrogen fixation is determined by precession-driven upwelling appears to indicate that the ocean s fixed nitrogen reservoir is resilient

and that the ocean biosphere can recover from even the most dramatic ecological changes says second author Daniel Sigman professor of geological

and geophysical sciences at Princeton university. y studying the response of nitrogen fixation to different environmental changes in the Earth s past we have found connections that may ensure that the ocean s fixed nitrogen level will always reboundsigman says. his suggests that an ocean over time has a relatively stable nutrient reservoir

and the resulting ocean upwelling. The investigators also compared the fluctuations in nitrogen fixation to historical records of water temperature and levels of ironâ##another crucial nutrientâ##both

#New evidence suggests giant ocean on Mars CALTECH (US) esearchers have found signs of an ancient delta on Mars where a river might have emptied once into a vast ocean.

This ocean, if it existed, could have covered much of Mars northern hemispheretretching over as much as a third of the planet. cientists have hypothesized long that the northern lowlands of Mars are a dried-up ocean bottom,

Although the new findings are far from proof of the existence of an ancient ocean,

and thus appears similar to the ocean basins found On earth. The border between the lowlands and the highlands would have been the coastline for the hypothetical ocean.

Researchers used new high-resolution images from the Mars Reconnaissance Orbiter (MRO) to study a 100-square-kilometer area that sits right on this possible former coastline.

and so did not provide evidence for an ocean. But the newly discovered delta is not inside a crater

or other confining boundary, suggesting that the water likely emptied into a large body of water like an ocean. his is probably one of the most convincing pieces of evidence of a delta in an unconfined regionnd a delta points to the existence of a large body of water in the northern hemisphere

This large body of water could be the ocean that has been hypothesized to have covered a third of the planet.

The embedded fossils are likely planktonic autotrophs free-floating tiny ocean organisms that produce energy from their environment.

The existence of these microfossils in diverse locations as far back as 3. 4 billion years ago suggests that the oceans probably had life in them for a very extended period of time adds Oehler.

#Discovery of water-containing gem points to vast oceans beneath the Earth The Earth transition zone is the part of the Earth that exists between the upper and lower mantle.

there is water, possibly massive oceans of it, deep beneath the Earth surface. The tiny gem was an accidental find

but might also contain more water than every surface ocean combined. This would make this discovery one of the biggest geological finds in decades.

For that reason, the open ocean is the first place robots are firing on targets. In more cluttered environments like the cities where most recent wars have been fought,

But when they get eaten close to the seafloor by animals that never come to the surface all of the carbon these roving fish were packing gets locked down at the bottom of the ocean Trueman explained.

The paper may have more relevance for our understanding of biogeochemical cycles internal to the oceans.

Ocean scientists have warned that plankton and corals will produce less calcium carbonate as the amount of CO2 in the atmosphere rises,

If the amount of atmospheric CO2 goes up as expected leading to a CO2 increase in the oceans the fish may produce more carbonate ions and thus more calcium carbonate.

but it could also reduce the average size of fish in the oceans. Smaller fish,

In December astronomers announced hints of watery plumes spurting from Jupiter's large moon Europa potentially giving us a peek into a vast ocean likely to exist beneath its ice.

Saturn's moon Enceladus stole back the limelight last week when NASA reported firm evidence of an ocean linked to geysers at its south pole (see diagram below.

Europa meanwhile appears to be covered entirely by an ocean sandwiched between a rocky core and a thin ice crust.

which would let nutrients from the surface make their way into the liquid ocean. It looks promising

Sampling the ocean may require a probe to land and drill through the ice since we don't know for sure

Hosting an ocean in contact with rocks boosts the chances that Enceladus hosts life because the rocks could leach elements like potassium sulphur and phosphorus vital for life into the water.

because it wouldn't be in contact with the rock says team member Jonathan Lunine at Cornell University in Ithaca New york. This gravity map hinting at a much larger ocean is a more favourable model for having some sort of life in Enceladus's interior.

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.

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.

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.

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.

and the weather conditions at the ocean surface they can detect the density of plankton in the water listen for clicks

#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.

Ocean Landscapes Need Protectiononce the moters complete their mission, they can be recovered from the water

and eject it into the ocean waters off Northern ireland coast. Theye concerned that it will raise the salinity

Yet the scientists found the environmental benefits of such a massive technological campaign were surprisingly small, especially in terms of protecting the ocean from the impacts of climate change.
