def: "An accumulation of water of varying size." [https://en.wikipedia.org/wiki/Body_of_water]
comment: The term body of water most often refers to large accumulations of water, such as oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. A body of water does not have to be still or contained; Rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water.

comment: A mountain is generally steeper than a hill, but there is no universally accepted standard definition for the height of a mountain or a hill although a mountain usually has an identifiable summit. The USGS had previously defined mountains as localised elevations of more than 300 meters; however, the organisation has accepted there are no technical definitions in the US. In ENVO, we primarily use the UNEP-WCMC classification to be compliant with SDG monitoring, but we can host other classifications on request: http://www.fao.org/sustainable-development-goals/indicators/1542/en/

The international definition proposed by the 2010 FAO Forestry Resource Assessment: "land spanning more than 0.5 ha with trees higher than 5 metres and canopy cover of more than 10 percent, or trees able to reach these thresholds in situ . It does not include land that is predominantly under agricultural or urban land use." - FAO.  2010. Global forest resources assessment 2010, Main report, FAO Forestry Paper 163. Rome.

They are typically composed of sand, although could be of any granular matter that the moving water has access to and is capable of shifting around (for example, soil, silt, gravel, cobble, shingle, or even boulders). The grain size of the material comprising a bar is related: to the size of the waves or the strength of the currents moving the material, but the availability of material to be worked by waves and currents is also important."

Where the direction of the shore turns inland (reenters) the longshore current spreads out or dissipates. No longer able to carry the full load, much of the sediment is dropped. This causes a bar to build out from the shore, eventually becoming a spit." [https://en.wikipedia.org/wiki/Spit_%28landform%29]

comment: The distinction between silt and clay varies by discipline. Geologists and soil scientists usually consider the separation to occur at a particle size of 2 μm (clays being finer than silts), sedimentologists often use 4–5 μm, and colloid chemists use 1 μm. Geotechnical engineers distinguish between silts and clays based on the plasticity properties of the soil, as measured by the soils' Atterberg limits. ISO 14688 grades clay particles as being smaller than 2 μm and silt particles as being larger. Mixtures of sand, silt and less than 40% clay are called loam. {xref="Properties"}

comment: An ice shelf may grow hundreds of miles out to sea.  Usually of great horizontal extent and with a level or gently undulating surface. Nourished by annual snow accumulation and also by the seaward extension of land glaciers. Limited areas may be aground. Ice shelves are much thicker than sea ice often filling embayments in the coastline of an ice sheet.. Currently, nearly all ice shelves are in Antarctica, where most of the ice discharged into the ocean flows via ice shelves. The mass balance of an ice shelf may have significant components of both gain and loss at the base. The seaward edge is termed an ice front.  The calving of an ice shelf forms tabular icebergs and ice islands. {xref="https://orcid.org/0000-0003-4808-4736"}

name: ribbon lake
def: "A lake that is long, narrow, and finger-shaped, usually found in a glacial trough. Its formation begins when a glacier moves over an area containing alternate bands of hard and soft bedrock. The sharp-edged boulders carried at the bottom of the glacier erode the softer rock more quickly by abrasion, thus creating a hollow called a rock basin. On either side of the rock basin, the more resistant rock is eroded less and these outcrops of harder rock are known as rock bars, which act as dams between which rainwater may accumulate after the retreat of the ice age, filling up the rock basin and creating a ribbon lake. A ribbon lake may also form behind a terminal or recessional moraine, both of which also act as dams, enabling water to accumulate behind them. A ribbon lake may also occur if a tributary glacier joins a main glacier. The increase in power can create a trough, which is filled with water from a river/meltwater to create a ribbon lake."

def: "A sea surface layer which is 1) not covered by ice and 2) laterally surrounded by either pack ice or land and pack ice." [https://orcid.org/0000-0003-4808-4736]
comment: A polynya is a Russian term for any non-linear shaped area of open water within the ice pack. Polynyas may contain brash ice and/or be covered with new ice, nilas or young ice; submariners refer to these as skylights.\n\nSometimes the polynya is limited on one side by the coast and is called a shore polynya or by fast ice and is called a flaw polynya. If it recurs in the same position every year, e.g. off the mouths of big rivers, it is called a recurring polynya. A temporary small clearing in pack ice which consists of small floes and brash in continuous local movement is called an unstable polynya; an opening which is flanked by large floes and therefore appears to be relatively stable is called a stable polynya.\n\nPolynyas range in size from relatively small to enormous. The largest polynya observed in the Antarctic was the Weddell Polynya of 1975-77, covering an area of 2x105km2.\n\nThe two main categories of polynya are sensible heat and latent heat, depending on the mechanism responsible for maintaining their presence. Latent heat polynyas are maintained by persistent katabatic winds that drain off the continent. Newly formed ice is advected away by the wind, leaving the surface ice-free and open to more ice formation. In this manner latent heat polynyas can be major sources of new ice production. Coastal polynyas are primarily of this type. Sensible heat polynyas are maintained by upwelling warm water that supplies a sufficiently large oceanic heat flux to the base of the ice to reduce its thickness, or melt it completely. These polynyas are not responsible for large quantities of new ice production. A polynya may also form by a combination of the sensible and latent heat processes.\n\n\nFrom the remote sensing/sea ice standpoint a polynya is a hole in the ice that ordinarily wouldn't be there - except that either the wind is creating it by pushing the ice away or there is something under the ice that is warmer than its surroundings and melting the ice that would otherwise be there. {xref="https://orcid.org/0000-0003-4808-4736"}

name: palsa
def: "A frost heave which is formed as the result of a perennial ice lens forming under soil, pushing a roughly oval portion land surface upwards." [https://en.wikipedia.org/wiki/Palsa]
comment: Palsas typically occur in areas with discontinuous permafrost, frequently peat bogs. A palsa consists, similarly to a pingo, of an ice core and overlying soil materials, in case of a palsa usually boggy soil. Palsas are characteristically found in areas with discontinuous permafrost and in such areas bay be the only reliable surface evidence of permafrost. A palsa needs large quantities of water for the formation of its ice core (i.e. ice lens), which is why they frequently emerge from and are bound by boggy soils, which can store enormous quantities of water in their pores. Palsas develop particularly in moorlands and are therefore also named palsamoors.

comment: From https://en.wikipedia.org/wiki/ [A mineral] is different from a rock, which can be an aggregate of minerals or non-minerals and does not have a specific chemical composition. The exact definition of a mineral is under debate, especially with respect to the requirement a valid species be abiogenic, and to a lesser extent with regards to it having an ordered atomic structure.

def: "An environmental material which is primarily composed of minerals, varying proportions of sand, silt, and clay, organic material such as humus, interstitial gases, liquids, and a broad range of resident micro- and macroorganisms." [https://en.wikipedia.org/wiki/Soil]
comment: 'In engineering terms, soil is referred to as regolith, or loose rock material that lies above the 'solid geology'. Soil is commonly referred to as "earth" or "dirt"; technically, the term "dirt" should be restricted to displaced soil.' https://en.wikipedia.org/wiki/Soil\n\n" The upper limit of soil is the boundary between soil and air, shallow water, live plants, or plant materials that have not begun to decompose. Areas are not considered to have soil if the surface is permanently covered by water too deep (typically more than 2.5 meters) for the growth of rooted plants.\n\nThe lower boundary that separates soil from the nonsoil underneath is most difficult to define. Soil consists of horizons near the Earth's surface that, in contrast to the underlying parent material, have been altered by the interactions of climate, relief, and living organisms over time. Commonly, soil grades at its lower boundary to hard rock or to earthy materials virtually devoid of animals, roots, or other marks of biological activity. For purposes of classification, the lower boundary of soil is arbitrarily set at 200 cm."

comment: ENVO bodily fluid classes differ from UBERON's treatment of bodily fluids. UBERON refers to the substance itself ("S"). We assert that UBERON's classes are the primary compositional component of the terms in ENVO ("S material"). Use of the ENVO terms is typically recommended when you wish to indicate that there may be other materials intermixed with S.
comment: This is distinct from classes such as http://purl.obolibrary.org/obo/UBERON_0001988 in that it refers to the environmental material composed primarily of feces rather than 'just' feces.

comment: ENVO bodily fluid classes differ from UBERON's treatment of bodily fluids. UBERON refers to the substance itself ("S"). We assert that UBERON's classes are the primary compositional component of the terms in ENVO ("S material"). Use of the ENVO terms is typically recommended when you wish to indicate that there may be other materials intermixed with S.

comment: In the United States, NOAA sea ice operations does not include superstructure icing as being sea ice. In sea ice operations however, sea ice is any form of ice found at sea which has originated from the freezing of sea water. It presents the main kind of floating ice encountered at sea. Except where it forms ridges, sea ice is up to a few metres thick, in which respect it differs from shelf ice.  Sea ice may be discontinuous pieces (ice floes) moved on the ocean surface by wind and currents (pack ice), or a motionless sheet attached to the coast (land-fast ice). In brief, it forms first as lolly ice (frazil crystals), thickens into sludge, and coagulates into sheet ice, pancake ice, or into floes of various shapes and sizes. Thereafter, sea ice may develop into pack ice and/or become a form of pressure ice.  Sea ice less than one year old is called first-year ice. Perennial ice is sea ice that survives at least one summer. It may be subdivided into second-year ice and multi-year ice, where multiyear ice has survived at least two summers. {comment="https://orcid.org/0000-0003-4808-4736"}

Geotechnical engineers distinguish between silts and clays based on the plasticity properties of the soil, as measured by the soils' Atterberg limits. ISO 14688 grades clay particles as being smaller than 2 μm and silt particles as being larger. Mixtures of sand, silt and less than 40% clay are called loam.

The term fuel oil is also used in a stricter sense to refer only to the heaviest commercial fuel that can be obtained from crude oil, i.e., heavier than gasoline and naphtha. {xref="https://en.wikipedia.org/wiki/Fuel_oil"}

The building or farm area where milk is harvested from the cow is often called a "milking parlor" or "parlor." The farm area where milk is stored in bulk tanks is known as the farm's "milk house." Milk is then hauled (usually by truck) to a "dairy plant," also referred to as a "dairy", where raw milk is further processed and prepared for commercial sale of dairy products. In New Zealand, farm areas for milk harvesting are also called "milking parlours", and are historically known as "milking sheds."' https://en.wikipedia.org/wiki/Dairy

Liming often improves plant growth and increases the activity of soil bacteria, but oversupply may result in harm to plant life.\nLiming can also improve aggregate stability on clay soils. For this purpose structure lime, products containing calcium oxide (CaO) or hydroxide (Ca(OH)2) in mixes with calcium carbonate (CaCO3), are often used. Structure liming can reduce losses of clay and nutrients from soil aggregates. {xref="Liming:(soil)"}

comment: Red soil typically derives from crystalline rock in warm, temperate, moist climates under deciduous or mixed forest. It has thin organic and organic-mineral layers, a black brown leached layer resting on an illuvium red layer. The majority of red soils have a loamy texture. Their chemical composition varies across regions, but often includes non-soluble material 90.47%, iron 3.61%, aluminium 2.92%, organic matter 1.01%, magnesium 0.70%, lime 0.56%, carbon dioxide 0.30%, potash 0.24%, soda 0.12%, phosphorus 0.09% and nitrogen 0.08%. \n\nOn the uplands, they are thin, poor and gravelly, sandy, or stony and porous, light-colored soils on which food crops like bajra can be grown. In contrast, on the lower plains and valleys they are rich, deep, dark colored fertile loam on which, under irrigation, can produce excellent crops like cotton, wheat, pulses, tobacco, jowar, linseed, millet, potatoes and fruits. {xref="Red:soil"}

comment: Everything under this parent must be a mass noun (i.e. not countable). All subclasses are to be understood as being composed primarily of the named entity, rather than restricted to that entity. For example, "ENVO:water" is to be understood as "environmental material composed primarly of some CHEBI:water".
comment: Instances of this class are portions of environmental materials, such as seawater in bucket, a water parcel in the photic zone of a lake, or the concrete that composes a building part. Instances of these portions may have fiat or non-fiat boundaries. For example, a water parcel has not physical boundaries, while the seawater in a bucket is bounded by the internal surfaces of the bucket.

def: "A layer of some material entity which is adjacent to one or more of its external boundaries and directly interacts with its immediate surroundings." [URL:http\://www.merriam-webster.com/dictionary/surface]
comment: This class is distinct from a geometric surface, which is two-dimensional. The idea of "uppermost" may be problematic. Further, the definition of layer (the superclass of surface in rev 133) references surface. This may be another issue. Perhaps this can be made into an inferred class using 'bounding layer of' some material entity, note that 'bounding layer' implies containment, which may not be valid here.

def: "MERGED DEFINITION:\nTARGET DEFINITION: An oceanographic feature that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface, replacing the warmer, usually nutrient-deplete surface water.\n--------------------\nSOURCE DEFINITION: A marine upwelling is a net flow of marine water to the surface of the water column from deeper regions. This is often a result of surface water displacement off continental coasts by wind action. Localised upwellings may also occur along divergent fronts around eddies and along some of the major oceanographic features. Deeper waters often have higher nutrient content; consequently blooms of primary producers, such as planktonic algae, are generally observed around upwelling zones."

def: "Particulate environmental material which is primarily composed of silt particles." [https://en.wikipedia.org/wiki/Silt]
comment: This definition is intentionally ambiguous to support the multiple thresholds set by different authorities. Some authorities consider this soil material that contains 80% or more silt and less than 12% clay. In the Udden-Wentworth scale (due to Krumbein), silt particles range between 0.0039 to 0.0625 mm, larger than clay but smaller than sand particles. ISO 14688 grades silts between 0.002 mm and 0.063 mm. In actuality, silt is chemically distinct from clay, and unlike clay, grains of silt are approximately the same size in all dimensions; furthermore, their size ranges overlap. Clays are formed from thin plate-shaped particles held together by electrostatic forces, so present a cohesion. According to the U.S. Department of Agriculture Soil Texture Classification system, the sand-silt distinction is made at the 0.05 mm particle size. The USDA system has been adopted by the Food and Agriculture Organization (FAO). In the Unified Soil Classification System (USCS) and the AASHTO Soil Classification system, the sand-silt distinction is made at the 0.075 mm particle size (i.e., material passing the #200 sieve). Silts and clays are distinguished mechanically by their plasticity. {xref="https://en.wikipedia.org/wiki/Silt", xref="https://sis.agr.gc.ca/cansis/glossary/t/index.html"}

Approximately 71% of the Earth's surface is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas. More than half of this area is over 3,000 metres (9,800 ft) deep. Average oceanic salinity is around 35 parts per thousand (ppt) (3.5%), and nearly all seawater has a salinity in the range of 30 to 38 ppt.

Marine mesoscale eddies are between about 10 and 500 km in diameter, and persist for periods of days to months. They may be formed when an ocean current develops an instability.

At low elevations, this typically results in eight months of the year having average temperatures greater than or equal to 10 degrees Celsius with the coldest monthly temperature averaging between 2 and 13 degrees Celsius." []
comment: As with most other climatic zones and conditions, multiple classification schemes have somehat different definitions and criteria. To quote from https://en.wikipedia.org/wiki/ "Several methods have been used to define the subtropical climate. In the Trewartha climate classification, a subtropical region should have at least eight months with a mean temperature of 10 °C (50.0 °F) or above. German climatologists Carl Troll and Karlheinz Paffen defined Warm temperate zones as plain and hilly lands having an average temperature of the coldest month between 2 °C (35.6 °F) and 13 °C (55.4 °F) in the Northern Hemisphere and between 6 °C (42.8 °F) and 13 °C (55.4 °F) in the Southern Hemisphere, excluding oceanic and continental climates. According to the Troll-Paffen climate classification, there generally exists one large subtropical zone named the warm-temperate subtropical zone,[4] which is subdivided into seven smaller areas.[5]\n\nAccording to the E. Neef climate classification, the subtropical zone is divided into two parts: Rainy winters of the west sides and Eastern subtropical climate.[6] According to the Wilhelm Lauer & Peter Frankenberg climate classification, the subtropical zone is divided into three parts: high-continental, continental, and maritime.[7] According to the Siegmund/Frankenberg climate classification, subtropical is one of six climate zones in the world.[8]"

comment: A similar term exists in linguistics and mathematics. An ecocline, or biological cline, is a related concept; however, may be better placed as a child of a class like "ecotone". Further, some definitions of "layer" require a layer's constiuent materials to have consistent properties, thus "cline" would not qualify as a subclass.

def: "Ice which is formed from water." [https://en.wikipedia.org/wiki/Ice]
comment: Water ice can appear transparent or opaque bluish-white color, depending on the presence of impurities or air inclusions. The addition of other materials such as soil may further alter its appearance.\n\nWhen speaking about ice on Earth, usually water ice is meant - the solid, crystalline form of water found in the atmosphere as snow crystals, hail, ice pellets, etc., and on the earth's surface in forms such as hoarfrost, rime, glaze, sea ice, glacier ice, ground ice, frazil, anchor ice, etc.\n\nThis form of water is, strictly speaking, called ice Ih, the Roman numeral I distinguishing it from more than a dozen other phases and the letter h distinguishing it from the metastable cubic phase ice Ic. Ice Ih is the only one of the several known phases of water ice that is stable at commonly occurring temperatures and pressures. (Some of the other forms have very unusual properties, ice VII, for example, being stable only at pressures above 22 400 kg/cm^2, but then existing at temperatures up to about 100C.)\n\nIt has an open structure with a specific gravity of 0.9166 which is slightly less than water; because the water molecules bond to their neighbors covalently only in four directions; it therefore floats on higher density water, where broken molecular bonds permit closer packing. All commonly occurring forms of ice are crystalline, although large single crystals are relatively rare except in glaciers. The ice crystal lattice possesses hexagonal symmetry that manifests itself in the gross forms of such single crystals as are sometimes found in snow. At an air pressure of one atmosphere, ice melts at 0 C by definition of the Celsius temperature scale. (Strictly speaking the equilibrium point among water, ice, and vapor occurs at +0.01C, the triple point.) On the other hand, ice does not invariably form in liquid water cooled below this temperature; it has a tendency to supercool, more so in the absence of ice nuclei.\n\nIn permafrost regions, ice may occupy voids in soils and rocks and may develop in a variety of forms. Ice may be colourless to pale blue or greenish-blue. It may appear white due to included gas bubbles; in exposures, ground ice may also appear black.\n\nIn nature ice is formed either by: (a) the freezing of water, (b) the condensation of atmospheric water vapour direct into ice crystals, (c) the compaction of snow with or without the motion of a glacier, or (d) the impregnation of porous snow masses with water which subsequently freeze.

comment: ENVO contains this top-level class, but all instances will be in GAZ. The definition is preliminary and will be aligned to BFO.\nhttps://en.wikipedia.org/wiki/  Ecozones correspond to the floristic kingdoms of botany or zoogeographic regions of zoology. Ecozones are characterized by the evolutionary history of the organisms they contain. They are distinct from biomes, also known as major habitat types, which are divisions of the Earth's surface based on life form, or the adaptation of plants and animals to climatic, soil, and other conditions. Biomes are characterized by similar climax vegetation. Each ecozone may include a number of different biomes. A tropical moist broadleaf forest in Central America, for example, may be similar to one in New Guinea in its vegetation type and structure, climate, soils, etc., but these forests are inhabited by plants and animals with very different evolutionary histories.

comment: The exact level of the tree line varies with local climate, but typically the tree line is found where mean monthly soil temperatures never exceed 10.0 degrees C and the mean annual soil temperatures are around 6.7 degrees C. In the tropics, this region is typified by montane rain forest (above 3,000 ft) while at higher latitudes coniferous forests often dominate. {xref="https://en.wikipedia.org/wiki/Altitudinal_zonation"}

comment: This variant of the desert climate is somewhat rare outside of Asia. A cold desert climate is typically found in temperate zones, almost always in the rain shadow of high mountains which restrict precipitation from the westerly winds, or in the case of Central Asia, from the monsoon. The Gobi desert in Mongolia is a classic example of a region with a cold desert climate. Though hot in summer, it shares the very cold winters of the rest of Central Asia. The Kyzyl Kum and Taklamakan deserts of Central Asia and the drier portions of the Great Basin Desert of the western United States are other major examples of BWk climates. The Ladakh region, lying in the Great Himalayas in India also has a cold desert climate.

This class is intended to capture littoral zones that are associated with marine, freshwater, and any other aquatic environments. Note that there is no single definition of the extent of the "littoral zone", associated with any water body. Here, we use definitions that will be more familiar to marine biologists rather than military organisations, although the latter can be added on request. This class will likely be superceded by a CMECs compliant class.

def: "A wet meadow is a type of wetland with soils that are saturated with water for part or all of the growing season." [https://en.wikipedia.org/wiki/Wet_meadow]
comment: Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. Wet prairies and wet savannas are hydrologically similar. Wet meadows may occur because of restricted drainage or the receipt of large amounts of water from rain or melted snow. They may also occur in riparian zones and around the shores of large lakes. Unlike a marsh or swamp, a wet meadow does not have standing water present except for brief to moderate periods during the growing season. Instead, the ground in a wet meadow fluctuates between brief periods of inundation and longer periods of saturation. Wet meadows often have large numbers of wetland plant species, which frequently survive as buried seeds during dry periods, and then regenerate after flooding. Wet meadows therefore do not usually support aquatic life such as fish. They typically have a high diversity of plant species, and may attract large numbers of birds, small mammals and insects including butterflies. {xref="https://en.wikipedia.org/wiki/Wet_meadow"}

def: "A piece of furniture is a movable object intended to support various human activities such as seating (e.g., chairs, stools and sofas) and sleeping (e.g., beds)." [https://en.wikipedia.org/wiki/Furniture]
comment: The assumption is that furniture is manufactured, which is arguable. Further, according to Black's Law Dictionary (http://thelawdictionary.org/furniture/) many classes can be subclasses of 'piece of furntiure': "This term includes that which furnishes, or with which anything is furnished or supplied; whatever must be supplied to a house, a room, or the like, to make it habitable, convenient, or agreeable; goods, vessels, utensils, and other appendages necessary or convenient for housekeeping; whatever is added to the interior of a house or apartment, for use or convenience. Bell v. Holding, 27 Ind. 173.The term “furniture” embraces everything about the house that has been usually enjoyed there, including plate, linen, china, and pictures. 1 Endicott v. Endicott, 41N. J. Eq. 96, 3 Atl. 157.The word “furniture” made use of in the disposition of the law. or in the conventions or acts of persons, comprehends only such furniture as is intended for use and ornament of apartments, but not libraries which happen to be there, nor plate. Civ.Code La. art. 477." However, this would eventually be absurd and limit other groupings. Perhaps some sort of 'furnishing' BFO:function would be a better way to handle this.

Some definitions do not make a distinction in size, as bulk freighters 1,000 feet (300 m) long on the Great Lakes are called oreboats. For reasons of naval tradition, submarines are usually referred to as 'boats' rather than 'ships', regardless of their size and shape." - https://en.wikipedia.org/wiki/Boat

comment: Material parts of astronomical bodies generally have boundaries formed by discontinuities in qualities, composition, or other physical characterisitcs. These boundaries are sometimes sharp, and sometimes diffuse, with different classification systems and communities declaring varying thresholds (e.g. for where a shoreline, forest, or other entity begins and ends). However, some boundaries are declared by fiat - that is, by arbitrary human convention or decree - particularly by regulatory or other authorities and communities of practice. The classes in this hierarchy attempt to offer generalisable definitions that allow multiple classfiication systems to map to and interoperate through. If desired, we can create classes that declare thresholds used by a given authority or community under the more generic ones, annotated with source information.
