Among the least characterized geobiological systems on Earth that can be accessed by scientific ocean drilling are deeply buried hydrocarbon reservoirs in sedimentary formations along continental margins. In particular, the microbiological and abiotic processes associated with a deeply buried coalbed in the ocean remain poorly understood and pose the following questions: (1) what role does subsurface microbial life play in the formation of hydrocarbon reservoirs? (2) Do deeply buried hydrocarbon reservoirs act as geobiological reactors that sustain microbial life by releasing nutrients and energy sources? (3) Do the conversion and transport of hydrocarbons and other reduced compounds influence biomass, diversity, activity, and functionality of deep subseafloor microbial populations? (4) What are the fluxes of both thermogenically and biologically produced organic compounds and how important are these for the carbon budgets in the shallower subsurface and the ocean? To address these important scientific questions, Integrated Ocean Drilling Program (IODP) Expedition 337 will drill and study the deep coalbed biosphere off the Shimokita Peninsula in the northwestern Pacific using the D/V Chikyu. This expedition aims to extend the maximum penetration of scientific ocean drilling to over 2200 meters below seafloor (mbsf) and will explore the microbial ecosystem associated with a deeply buried coalbed (i.e., a habitat that had never been accessed by previous scientific ocean drilling). The riser drilling and operational strategy will involve spot coring in representative intervals throughout the hole, continuous mud gas logging (gas composition and stable isotope), continuous geochemical and sedimentological analysis of cuttings retrieved during riser drilling, wireline logging from 647 to 2200 mbsf including sampling of pristine formation fluids, and pressure core sampling in methane hydrate–bearing strata in an adjacent hole under the in situ pressure condition. The cored intervals in the deep hole will be subject to intense sampling for shipboard and shore-based investigations. In addition, we will address scientific problems related to CO2 sequestration in offshore coalbed formations through ex situ experiments using the recovered core materials. The latter experiments will investigate how supercritical CO2 interacts with minerals, organic matter, and life in the deep subsurface and examine how CO2 storage may affect biogeochemical carbon cycling. Ultimately, Expedition 337 will greatly advance our knowledge of the coalbed subseafloor hydrocarbon system and the deep biosphere, including its CO2 sequestration potential.

The Answer is Helium-3
This is a work in progress.
A self-initiated project for my university studies, this motion graphics piece is designed as a pitch to the United Nations for mining rights, by the client Space X - a private aerospace corporation who has expressed interest in harvesting helium-3 on the Moon.
Helium-3 is a very stable yet extremely rare isotope of helium - so rare in fact that less than a few kilograms of the gas exist anywhere on the planet. The reason for this is the Earth's atmosphere and magnetic field - helium-3 produced in our Sun and carried throughout the Solar System via the solar winds is either deflected by the Earth's magnetic field, or absorbed into the upper atmosphere.
The stability of helium-3 makes it a prime candidate fuel for nuclear fusion - the same process used in the Sun, where two atoms are fused together under immense pressures and temperatures to release a phenomenal amount of energy - which, if harnessed, can provide for our electrical needs.
When used as fuel in a nuclear fusion reaction, helium-3 can potentially release more than 10x the amount of energy of any other resource in history. What's more, the reaction is what's called a 'perfect cycle', meaning no harmful waste or hazardous by-products whatsoever are produced.
While the Earth is devoid of helium-3, millions of tonnes of the gas are believed to be present on the Moon. Its lack of both an atmosphere and a magnetic field has allowed helium-3 to build up in the lunar soil for billions of years. This effectively means the Moon could hold the answer to our energy crisis - an enormous supply of the most powerful fuel resource ever discovered; a resource with the potential to satisfy our energy needs for hundreds, if not thousands, of years into the future - with zero emissions or waste.

Non-Local Quantum Coherence In Photosynthesis
Animal Olympians Inspire Engineers - June 2012
Excerpt: Photosystem II, the only known biological system that can harness visible light for the photooxidation of water, produces most of the oxygen in Earth’s atmosphere through a five-step catalytic cycle (S0-to-S4 oxidation states). Light-harvesting proteins in the complex capture solar photons that energize the manganese-calcium cluster and drive a series of oxidations and proton transfers that in the final S4 state forms the bond between oxygen atoms that yields molecular oxygen.

Scientists unlock some key secrets of photosynthesis - July 2, 2012
Excerpt: "The photosynthetic system of plants is nature's most elaborate nanoscale biological machine," said Lakshmi. "It converts light energy at unrivaled efficiency of more than 95 percent compared to 10 to 15 percent in the current man-made solar technologies.,, "Photosystem II is the engine of life," Lakshmi said. "It performs one of the most energetically demanding reactions known to mankind, splitting water, with remarkable ease and efficiency.",,, "Water is a very stable molecule and it takes four photons of light to split water," she said. "This is a challenge for chemists and physicists around the world (to imitate) as the four-photon reaction has very stringent requirements."

Researchers find more evidence of quantum processes at work in photosynthesis - December 2011
Excerpt: This result means the team was able to demonstrate in a clear way, that coherence really is involved in the way that energy is transported during photosynthesis, which means that as far as photosynthesis is concerned, micro-biologists are likely going to have to go back and take a new fresh look at what is really going on in a process that was up till now, thought to be rather well understood.

Notes:
The oldest sedimentary rocks on earth, known to science, originated underwater (and thus in relatively cool environs) 3.86 billion years ago. Those sediments, which are exposed at Isua in southwestern Greenland, also contain the earliest chemical evidence (fingerprint) of ‘photosynthetic’ life [Nov. 7, 1996, Nature]. This evidence had been fought by materialists since it is totally contrary to their evolutionary theory. Yet, Danish scientists were able to bring forth another line of geological evidence to substantiate the primary line of geological evidence for photo-synthetic life in the earth’s earliest sedimentary rocks.

http://adsabs.harvard.edu/abs/2004E&PSL.217..237R;
Moreover, evidence for ‘sulfate reducing’ bacteria has been discovered alongside the evidence for extremely ancient photosynthetic bacteria:
When Did Life First Appear on Earth? – Fazale Rana – December 2010
Excerpt: The primary evidence for 3.8 billion-year-old life consists of carbonaceous deposits, such as graphite, found in rock formations in western Greenland. These deposits display an enrichment of the carbon-12 isotope. Other chemical signatures from these formations that have been interpreted as biological remnants include uranium/thorium fractionation and banded iron formations. Recently, a team from Australia argued that the dolomite in these formations also reflects biological activity, specifically that of sulfate-reducing bacteria.
http://www.reasons.org/when-did-life-first-appear-earth
Moreover, as Fazale Rana indicated in the preceding paper, we have evidence of sulfate reducing bacteria as well as photosynthetic bacteria in the most ancient sedimentary rocks. This is a ‘surprising’ empirical finding for the first life in the oldest sedimentary rocks on earth for sulfate reducing and photosynthetic bacteria are 'interdependent',,, On the third page of this following site there is a illustration that shows some of the interdependent, ‘life-enabling’, biogeochemical complexity of different types of bacterial life on Earth.,,,
