  • Interesting fact: In order to mate, a male deep sea anglerfish will bite a female when he finds her. The male will never let go and will eventually merge his body into the female and spend the rest of his life inside the female mate. The males internal organs will disappear apart from the testes that are needed to for breeding
    • Deep-sea at some distance from the shore; as, deep-sea fishing.
    • a Deep-sea Of or pertaining to the deeper parts of the sea; as, a deep-sea line (i. e., a line to take soundings at a great depth); deep-sea lead; deep-sea soundings, explorations, etc.
    • Deep-sea taking place in the deeper parts of the sea; as, deep-sea exploration.

  • Interesting fact: Jellyfish can sense a storm 10 to 15 hrs. before it actually occurs and leaves the shore and go into the deep sea.
    • deep-sea Of or pertaining to the deeper parts of the ocean: as, deep-sea dredging.
    • deep-sea the line, made of steel wire, weighing about 14½, pounds to the nautical mile;
    • deep-sea machinery for regulating the lowering of the sinker and for reeling in the wire with the cylinder attached in such a manner that the irregular strain due to the motion of the ship may be guarded against and the danger of breakage thus reduced to a minimum. In the deepest accurate sounding yet made the bottom was reached at the depth of 4,655 fathoms, but owing to the breaking of the wire no specimen was obtained. This sounding was made on the “Tuscarora” by Commander G. E. Belknap, U.S. N., in north latitude 44° 55′ , east longitude 152° 26′ . The deepest sounding yet made in which a specimen of the bottom was brought up was that of the United States Coast Survey steamer “Blake,” off Porto Rico, the depth there reached being 4,561 fathoms.

    “Usually the greatest boasters are the smallest workers. The deep rivers pay a larger tribute to the sea than shallow brooks, and yet empty themselves with less noise.”
  • William Shakespeare
    “My bounty is as boundless as the sea, my love as deep. The more I give thee, the more I have, For both are infinite”

What secret does it keep
While tides a-roaring leap
Ten thousand years?"

The deep and rolling sea
Is ever grandly singing, Lord,
To my bowed soul, of Thee.

That calls beneath the sea;
And all the deep grows pale with sleep
And vague expectancy.

Could yesterday be seen—
Only a tint like the sea-shell,
Deep in a prison of green.

While under me the troubled sea
Lies forty spasms deep."

The spectral camp was seen,
And, with a sorrowful, deep sound,
The river flowed between.

In science:

They rely on a good angular resolution, which above 10 TeV is essentially determined by the scattering length of light in the medium, yielding a median error angle on the neutrino direction of about 0.5◦ for IceCube and 0.4◦ for ANTARES (note that one can expect 0.1◦ resolution for a km3 deep-sea detector).
High-Energy Neutrino Astronomy: Status and prospects for cosmic-ray physics
The non-valence spin-flavour structure of the proton extracted from semi-inclusive measurements of polarized deep inelastic scattering may depend strongly on the transverse momentum (and angular) acceptance of the detected final-state hadrons which are used to determine the individual polarized sea distributions.
The Spin Structure of the Proton
When we relax the transverse momentum cut-off, increasing the acceptance of the experiment, the measured strange sea polarization changes sign and becomes negative (the result implied by fully inclusive deep inelastic measurements).
The Spin Structure of the Proton
Valuable information on the performance of cables and connectors under the harsh deep-sea conditions were gathered.
