The Grayson Navy are the space forces for the planet Grayson, a space nation in the Honor Harrington universe created by the science fiction author David Weber.

In the internal history of the Honorverse, Grayson was settled by emigrants from Earth motivated by their religion, which called for a withdrawal from the technocratic society of Earth, a society the future inhabitants of Grayson believed to be subversive of true human potential and spirituality. The planet picked for the settlememnt was one very rich in heavy metals; local life had adapted, but human settlers suffered a very high death rate as well as a high rate of non-lethal, but debilitating poisonings from the high environmentyal levels of lead, mercury and antimony. The settlers' biology has partially adapted since, but to this day, agriculture on Grayson remains a chancy undertaking, and food Graysonites eat with safety can still poison an outsider.

Until Grayson joined the Manticoran Alliance, the Grayson Navy was hopelessly obsolete, and most of it was destroyed during a brief war with it's neighbor Masada, just before it officially joined the Manticoran Alliance (Two Manticoran destroyers were also lost during the incident, with two cruisers badly damaged.)

After joining the Alliance, Grayson received massive technological boosts from Manticore, and quickly rebuilt it's navy with the new technology. Grayson ships are different from Manticoran, Havenite, and Andermani ships in that they mount fewer weapons, but the weapons themselves are much larger. They also use hydrogen based fission reactors to power their ships that are far safer and more efficient than anybody on Manticore ever thought possible. Later Manticoran and Grayson ship designs were designed in concert and are largely similar in design and function.

The Grayson Navy has no Marines. All shipboard troops are from the Grayson Army. Grayson Steadholders (roughly equivilant to Manticoran Dukes) are required to keep at least three of their armsmen (personal bodyguards) with them, even while on duty.

The Grayson Navy consists of it's main navy, with it's regular chain of command, and the Protector's Own Squadron, which answers directly to the Protector, ruler of Grayson, currently commanded by Admiral Steadholder Honor Harrington, the Protector's Champion, with Admiral Alfredo Yu as her second-in-command. The Protector's Own is an oddity in itself, since a large portion of it's personel are expatriates and former prisoners of the People's Republic of Haven, which the Manticoran Alliance is currently at war with.

DEEP SEA PHYSICAL OCEANOGRAPHY is the study of flow dynamics, geology and geophysics, and thermo and hydrodynamics of the deep sea, where "deep sea"=below 50 ft.

The flow of the ocean in deep sea is dramatically slowed than that of the surf zone and suface flow.This is due to the salt content being larger than that on the surface. Also, the average temperature drops about 20 or so degrees. The temperature can be found with the formula:

                              T = a * 3.14/D

  In this, T is the temperature, a=30.77, and D is depth. The formula uses Celcius, so you have to use the conversion formula:

                     9/5C + 32 = F

Where C is Celcius.

So, in the Marianas Trench, T=32 degrees F, which is about as cold as it gets. But, as we have seen with the ALVIN submersible, we have found that the deep sea isn't just a cold abyss. There are hydrovents, and some reach up to 100 degrees C. So, according to the formula above, the temperature of the area around the hydrovent is:

                     C = T + T′

Where in this, we find that C is the degrees in Celcius, T is the temperature given above, and T' is the temperature of the vent (all of which are in Celcius, of course).

Now, with temperature there is going to be entropy. When ALVIN discovered the hydrovents, the sea life and entropy were evident. Well, with the formula for entropy in the deep sea (any where, for that matter in the ocean) is:

                      S = TA/dt

Where S is entropy, T is temperature (which also could be C in the equation presented above)and A is area of the rock formation, and dt is the differential of time under consideration.

How this formula is measured is the total number that entropy (sea life, disorder, so forth and on) on over the area A.

Flow patterns and dynamics follow basic hydrodynamical laws, but because it's more dense, the flow is measured as a whole, not coordinate by coordinate. This is measured by tensors, and this is a fairly new field.

The Church House, South Tawton, is a building in Devon, UK . It is a small and robust late 15th - early 16th century building constructed of granite with a thatched roof. It lies just inside the northern edge of the Dartmoor National Park, at the heart of the village of South Tawton, and is a Grade II Listed historic building, in a Conservation Area, with the church of Saint Andrew rising dramatically behind it. The proximity of the building to this Grade 1 church, in the centre of the village, is a significant attraction for visitors to the area.

Church House is an outstanding example of a special type of medieval community building. The community of the Parish of South Tawton has used Church House for over 500 years and remarkably it is still owned by the Incumbent and Church Wardens, as Trustees on behalf of the Parish and is run by the Church House Management Committee. Local documentary evidence (which begins in 1524) has produced data about the history of farming, land management and the evolution of the distinct group of community buildings called "Church Houses" during the Reformation; a period of major importance in national history.

A special feature is the roof structure, which preserves cruck trusses and rare smoke-blackened thatch. Currently the building is used for Junior Church, Scout meetings, social events in connection with church occasions (e.g. baptisms and funerals, harvest suppers), painting classes, art exhibitions, committee meetings, and similar activities.
