Iceberg: greed driven industrialists and more

Admiral Sandecker, in spite of his boiler plate exterior, was at heart a humanitarian, and he rarely disguised his disgust and hatred for greed-driven indutrialists

(Wikipedia's search function redirects industrialist to business magnate!) A business magnate is an entrepreneur who has achieved wealth and prominence from a particular industry (or industries). Other, similar terms are czar, mogul, tycoon, baron, or oligarch.

The word magnate itself derives from the Latin word magnates (plural of magnas), meaning "great person" or "great nobleman."
The word tycoon is derived from the Japanese word taikun, which means "great lord," and it was used as a title for the shogun. The word entered the English language in 1857 with the return of Commodore Perry to the United States. U.S. President Abraham Lincoln was humorously referred to as the Tycoon by his aides John Nicolay and John Hay. The term spread to the business community, where it has been used ever since.
The word mogul refers to the Mughal Empire (mughal being Persian or Arabic for "Mongol") of the Indian subcontinent that existed between 1526 and 1857: the early Mughal emperors claimed a heritage dating back to Mongol ruler Genghis Khan. The modern meaning of the word is supposedly derived from the storied riches of the Mughal emperors, who for example produced the Taj Mahal.
As the term industrialist (from Latin industria, "diligence, industriousness") was more widely used in the context of "old world" physical industries such as steel, oil, newspapers,shipping and rail transport, it has largely been superseded by the other, more modern terms that encompass a wider range of virtual business and commercial activity.

  "So they trike a bonanza on the sea floor."

"Bonanza" is a term used by miners in regard to a large vein or deposit of ore, and commonly refers to The Comstock Lode. (It's also the name of a popular Western TV show starring Lorne Greene and Michale Landon.)

Origin:
1835–45, Americanism ;  < Spanish:  literally, smooth sea (hence, good luck, rich vein of ore), nasalized variant of Medieval Latin bonacia,  equivalent to Latin bon ( us ) good + ( mal ) acia  calm sea < Greek malakía  softness ( malak ( ós ) soft + -ia -ia)

"Dr. Matajic was studying currents below a depth of ten thousand feet, trying to prove a pet theory of his that a deep layer of warm water had the capacity to melt the Pole if only one percent of it could be diverted upward."

 There is no deep layer of warm water.

Deep Ocean Water (DOW) is the name for cold, salty water found deep below the surface of Earth's oceans. Ocean water differs in temperature and salinity, with warm, relatively non-salty water found at the surface, and very cold salty water found deeper below the surface layer. Deep ocean water makes up about 90% of the volume of the oceans. Deep ocean water has a very low temperature, typically from 0 °C (32 °F) to 3 °C (37 °F), and a salinity of about 3.5% (35 psu).^[1]
In specialized locations such as the Natural Energy Laboratory of Hawaii NELHA ocean water is pumped to the surface from approximately 3000 feet deep for applications in research, commercial and pre-commercial activities. DOW is typically used to describe ocean water at sub-thermal depths sufficient to provide a measurable difference in water temperature.
When deep ocean water is brought to the surface, it can be used for a variety of things. Its most useful property is its temperature. At the surface of the Earth, most water and air is well above 3 °C. The difference in temperature is indicative of a difference in energy. Where there is an energy gradient, skillful application of science and engineering can harness that energy for productive use by humans. Assuming the source of deep ocean water is environmentally friendly and replenished by natural mechanisms, it forms a more innovative basis for cleaner energy than current fossil-fuel-derived energy.
The simplest use of cold water is simply for air conditioning: using the cold water itself to cool air saves the energy that would be used by the compressors for traditional refrigeration. Another use could be to replace expensive desalination plants. When cold water passes through a pipe surrounded by humid air, condensation results. The condensate is pure water, suitable for humans to drink or for crop irrigation. Finally, via a technology called Ocean thermal energy conversion, the temperature difference can be turned into electricity.
