We must reach the Seafloor.
The Seafloor has been well mapped and picked over by now.
The mission of Seafloor survey remains a core application for this technology.
About half the oceans' Seafloor, mostly at deeper depths, became completely oxygen-free.

What happens when
inexorable geological forces shove a giant Seafloor mountain beneath a continent?
Several multinationals are
developing systems to provide electric power across the Seafloor- think subsea power sockets.
ASV BEN has a state-of-the art Seafloor mapping system that can map depths
reaching 650 feet.
It crawls over the Seafloor like a robotic vacuum cleaner, munching on everything in its path.
BEN is
a robotic vessel designed to aid the ship's crew in the colossal task of Seafloor survey.
The company needed to use DVL technology that customers
would trust to assess velocity and altitude above the Seafloor.
Seafloor depth
and submerged obstructions will dictate where the ship can go and where towed equipment can be deployed.
The Shell Ocean Discovery XPRIZE challenged us to develop effective, efficient, and better ways of mapping the Seafloor.
However, due to technical difficulties, the divers were only able to screw one helix anchor to the Seafloor.
Only 15% of the Seafloor has been mapped by modern methods,
and perhaps 5% has ever been seen by human eyes.
In fact, sonar data showing layers of Seafloor sediments suggest that these pockmarks have been
inactive for the last 50,000 years.
There are two main types: floating(suspended in the water column above the Seafloor) and fixed(located near or on the Seafloor).
Only 15% of the Seafloor has been mapped with modern methods,
and less than 5% has ever been seen by human eyes.
About a large portion of the ocean's Seafloor, for the most part at more profound profundities,
turned out to be totally without oxygen.
The result of the SDB
mapping is a 3D elevation model of the Seafloor- one of the cornerstone data layers for the entire project.
Seafloor pockmarks have been found elsewhere around the world,
and have been associated with releases of methane gas or other fluids from the Seafloor.
Fugro has won a contract to collect Seafloor data for the Office of Environment and Heritage(OEH),
on behalf of the New South Wales Government, Australia.
In 1925, Scripps began taking Seafloor water temperature measurements,
and the daily collection is still completed by hand and maintained by the institution's Shore Stations program.
The cluster is 20 km
long and six km wide and the Seafloor 4890 metres deep, with
the highest point in the cluster rising up to 3998 metres.
Fugro said it has won a contract to collect Seafloor data for the Office of Environment and Heritage(OEH),
on behalf of the New South Wales Government, Australia.
You can see how the naturally deep harbor has made Portland ideal for large tankers and ships,
and where the Seafloor has been dredged to facilitate this.
In the current SDB process,
we use manual stereo photogrammetry methods to measure Seafloor ground control points in digital satellite imagery,
but this is extremely time consuming,” said Goodrich.
What we know is that long after these experiments were conducted, the Seafloor is still scarred,
and devoid of the hard nodule substrate required to support the Seafloor communities.
In completing this mission, the Healy crew deployed specialized instruments on ice floes and
placed subsurface moorings on the Seafloor, which will remain in the Arctic until next year.
Additional ships added a sonar device called a towfish
that's towed at depth of 100 meters above the Seafloor, and a self-propelled autonomous underwater vehicle(AUV)
which can travel even deeper.
