Collaborative work of: Margaret O'Brien, Sophie Hou, Chase LeCroy, and Mark Schildhauer SophieHou, orcid.org/0000-0002-8087-1775 This ontology was generated from an ontology revision in WebProtege http://odo.nceas.ucsb.edu ontology in progress for DataONE MSTMip/LTER Carbon cycling use cases system definition_Contributor Margaret O'Brien, orcid.org/0000-0002-1693-8322, Shild O'Brien, pers comm. 2015-02-15 Margaret O'Brien, orcid.org/0000-0002-1693-8322 The "contributor" Annotation Property" is to record the name of the those contributing to the resource. If there is any potential ambiguity, an identifier should be added, including the system to which it belongs. "contributor" is an OWL "Annotation property" that names the person contributing the content, so s/he can be contacted, especially during development. definition_Source Schildhauer, orcid.org/0000-0003-0632-7576 "definitionSource" is the Annotation property that can be used to provide the reference source or Authority for the "definition" (of interest), as an ISBN,DOI, bibliographic citation, etc. to the source of the "definition" contained in an associated "definition" Annotation property that is attached (annotated) to the concept. Ideally a definition Source is structured in a well-known and accepted format, that provides an unambiguous pointer to a source reference, but often even some accurate indication of a reference source is better than nothing at all. Schildhauer, pers comm, 05Feb2015, orcid.org/0000-0003-0632-7576 description "description" is an OWL "Annotation property" that contains a a more verbose, less prescriptive natural language explication of the concept to which it is attached (or applied, or annotated) in contrast to a "definition" Annotation property. Use the "definition" Annotation property for scientific concepts when possible, as opposed to the "description" Annotation property Schildhauer, pers comm, 05Feb2014, orcid.org/0000-000300632-7576 Schildhauer, orcid.org/0000-0003-0632-7576 description_Source Schildhauer, pers comm, 05Feb2015, orcid.org/0000-0003-0632-7576 Schildhauer, orcid.org/0000-0003-0632-7576 "description_Source" is the Annotation property that can be used to provide the reference source or Authority, as an ISBN,DOI, bibliographic citation, etc. to the source of the "description" contained in an associated "description" Annotation property that is attached (annotated) to some concept. Ideally a descriptionSource is structured in a well-known and accepted format, that provides an unambiguous pointer to a source reference, but often even some accurate indication of a reference source is better than nothing at all. As description Annotation properties are often not as rigorous, and hence looser and more verbose than definition Annotation properties, these fields may be more readily used for informal pedagogical advice and direction rather than being proscriptive has_Exact_Synonym The DataONE carbon flux ontology uses synonyms for terms that may not be well defined. But we know that they are used, and refer to an owl class. I.e., a concept can have a synonym, but a concept should not be a synonym. ad hoc has_Related_Synonym Margaret O'Brien, 2015-03-18 mobb has_Exact_Synonym is an OWL annotation property that holds an alternate name or lexical variant of an owl class. We are not planning to use has_Broad_Synonym or has_Narrow_Synonym at this time. although other ontologies do. the concepts of "broad" and "narrow" imply relationships that could be better described with the class hierarchy. example_Of_Usage O'Brien, pers comm, 2015-02-19 "example_Of_Usage" is an OWL annotation property to record examples of how the concept or property should be used. "example_Of_Usage" is for providing examples. It should contain actual sample strings for the resource it applies to. longer, text descriptions of good practice for the resource belong in the "description" annotation. O'Brien, pers comm, 2015-02-19 Margaret O'Brien, orcid.org/0000-0002-1693-8322 has_Related_Synonym has_Related_Synonym is an owl annotation property to hold a term that is not an owl class, but is a primary term found in the literature but is not necessarily correct. The DataONE carbon flux ontology uses synonyms for terms that may not be well defined. But we know that they are used, and refer to an owl class. I.e., a concept can have a synonym, but a concept should not be a synonym. ad hoc! has_Exact_Synonym mobb Margaret O'Brien, 2015-03-18 rdfs:label Margaret O'Brien, orcid.org/0000-0002-1693-8322 Carbon_Flux_NASA, definition_Source, rdfs:label rdfs:label is a built in annotation property, and W3C does not give guidelines beyond the definition. In the DataONe Carbon Flux ontology, we use rdfs:label for a human-readable version of the resource's name, but adhere to a particular pattern. Our goal is that content of rdfs:label are not broken into individual terms arbitrarily. 1. Our practice is to separate individual words in the rdfs:label with underscores, but maintain capitalization consistent with the conventions of the resources type (e.g., camel case for properties, capitalized words for classes, capitalized abbreviations and acronyms). 2. include namespace in the label, if resource is imported.

(GPP is sometimes confused with Gross Primary productivity, which is the rate at which photosynthesis or chemosynthesis occurs.) For most purposes (including this one) the two can be the same. It's most practical to measure production over a given time interval and area, and that amounts to an areal rate.

People using pprod data should know enough to evaluate basic diifferences between methods. eg, an ecologist ought to know that "allometrics" are an average for a species or population, not a community. or an oceanographer ought to know the difference between light-dark O2 and light-dark C14 inclubations. So if you want "community NPP", and you see the method used was allometric -- you'd know you had to understand the community composition to know if prod of one or a few groups is enough. if you wanted "community NPP",in ocean data, you would know that O2 light-dark was OK, but that C14 update might actually be GPP A regular and systematic way of accomplishing something, characteristic of a particular discipline or field of knowledge. Chase LeCroy, orcid.org/0000-0002-1338-9436 Field Method strawman definition from margaret: a Field_Method is a method for determining a component of primary production that involves observations or measurements of the real world. A field method may have steps which could be considered 'modeling' (such as development of an allometric model of tree growth based on height), but measurements "in the field" (eg, of trees) are always involved. compare to Modeled_Method. Modeled Method strawman definition from Margaret a Modeled_Method (is Simulated_Method better?) uses only data obtained from some source. It does not directly measure any real phenomenon. Peak Biomass Harvest Method The "Peak Standing Biomass Harvest" method is recommended for grasslands that meet the following criteria: 1) there is little carryover of living biomass from previous years due to distinct dormant season or fire during the dormant season or the previous year's biomass can be easily recognized and separated from the current year's biomass (living and dead) 2) the growing season is sufficiently short or plant material is of such low quality that decomposition of biomass produced can be ignored 3) consumption of plants by herbivores is minimal (i.e., large grazers are absent and small vertebrates and invertebrates can be ignored). Fahey and Knapp, 2007, p33 Peak_Biomass_Harvest_Method is an estimate of above ground NPP based on the above ground biomass harvested once, usually near the end of the growing season, at or just after the time of peak biomass Fahey and Knapp, 2007, p33 Eddy Covariance Method http-en.wikipedia.org/wiki/Eddy_covariance add these synonyms (near? exact?): also known as eddy correlation and eddy flux It is frequently used to estimate momentum, heat, water vapor, carbon dioxide and methane fluxes. The technique is mathematically complex, and requires significant care in setting up and processing data. To date, there is no uniform terminology or a single methodology for the Eddy Covariance technique. The technique has additionally proven applicable under water to the benthic zone for measuring oxygen fluxes between seafloor and overlying water.[6] In these environments, the technique is generally known as the eddy correlation technique, or just eddy correlation. For CO2.... tbd http-en.wikipedia.org/wiki/Eddy_covariance The eddy covariance method is an atmospheric measurement technique to measure and calculate vertical turbulent fluxes within atmospheric boundary layers, and analyzes high-frequency wind and scalar atmospheric data series, to yield exchange rates (fluxes) of trace gasses. Carbon14 Uptake Method O'Brien, pers comm 2015-02-15 Fahey and Knapp, 2007 A C14 uptake method is typically used in aquatic environments, for microscopic autotrophs (phytoplankton). C14 is a radioactive tracer added as bicarbonate, and its concentration determined in the plankton after removed by filtration. Measurement scales tend to be small (hours and liters) relative to the scales of other field methods. Photosynthetic and heterotrophic activity are tightly coupled in planktonic systems (Fahey and Knapp, 2007). If the incubation is short enough, the result will be GPP (gross), because presumably, no labeled c14 was recycled (or respired) by the cells. Sometimes researchers conduct "light-dark bottle", but the dark bottle tells you something different than in o2 light-dark. It gives you dark CO2 uptake, so subtract this from light CO2 uptake if you want autotrophic GPP. Oxygen Evolution LightDark Method The stoichiometry of phtotsynthesis is well known. So you can measure O2 evolution, and back calculate to CO2 use. usually, there is a "iight bottle" and "dark bottle". O2 evolution in the Light bottle is the net result, or sum, of all processes (GPP, Autotrophic resp, and probably some heterotrophic respiration too, because heterotrophs are hard to exclude). So Light bottle = NPP. Dark bottle is respiration, probably total, eg, autotrophs + heterotrophs. So light + dark = GPP (or about as close as you can get with a field measurement, and assume that heterotrophs aren't respiring much.) Allometric Method Begon, M., Harper, J.L., Townsend, C.R. Ecology: Individuals, Populations, and Communities. Third Edition. Blackwell Science. 1996. O'Brien, pers comm, 2014-10-15 an allometric method is usually accomplished with a combination of measurements that are tailored to the organism, e.g, size, growth rate, carbon content, plus some loss terms. SBC's dataset 21 has a good example of an allometric method for kelp.

Biome-BGC is an ecosystem process model that estimates storage and flux of carbon, nitrogen and water. Biome-BGC is a computer program that estimates fluxes and storage of energy, water, carbon, and nitrogen for the vegetation and soil components of terrestrial ecosystems. We call it a process model because its algorithms represent physical and biological processes that control fluxes of energy and mass. The model uses a daily time-step. This means that each flux is estimated for a one-day period. Between days, the program updates its memory of the mass stored in different components of the vegetation, litter, and soil. Weather is the most important control on vegetation processes. Flux estimates in Biome-BGC depend strongly on daily weather conditions. Model behavior over time depends on the history of these weather conditions, the climate.

Chung-Yi Hou, orcid.org/0000-0002-8087-1775 http-www.cccma.ec.gc.ca/ctem/ The Canadian Terrestrial Ecosystem Model (CTEM) is designed to serve as the terrestrial carbon cycle component in the coupled Canadian Centre for Climate Modelling and Analysis (CCCma) atmosphere-ocean general circulation model (GCM). CTEM is a dynamic vegetation model that is able to grow vegetation from bare ground and provides time-varying vegetation structural attributes (e.g., leaf area index (LAI), vegetation height, rooting depth and distribution, and canopy mass) to the land surface scheme it is coupled with. Other than simulating vegetation biomass and its structural attributes CTEM also simulates amount of carbon in its dead pools (litter and soil organic matter), and thus is able to provide net fluxes of CO2 between the land and the atmosphere. This documentation provides a brief description of CTEM 1.0/1.1 and the manner in which CTEM is coupled to Canadian Land Surface Scheme (CLASS, version 2.7) [Verseghy et al. 1993; Verseghy, 1991]. Coupled CLASS 2.7/CTEM 1.0 are implemented in CCCma's coupled carbon climate model.

ISAM_Mstmip_Version1_Modeled_Method Chung-Yi Hou, orcid.org/0000-0002-8087-1775 Integrated Assessment Modeling (IAM) is a new important research methodology for examining the complex interactions among physical, and human systems. Rather than actually using many of the multi-dimensional and complicated expert models, IAM build on the knowledge achieved by each individual scientific discipline. The uses of such tools need to explicitly recognize and address the existence of considerable uncertainty and scientific debate surrounding climate issues. Our existing Integrated Science Assessment Model (ISAM) for assessment of climate change (Jain et al., 1994) consists of coupled modules for representation of the carbon cycle, effects of greenhouse gas emissions and aerosols on atmospheric composition, effects on global temperatures using an energy balance model, and processes affecting sea level change. This model has been used to estimate the relation between the time-dependent rate of greenhouse gas emissions and quantitative features of climate global temperature, the rate of temperature change, and sea level that are thought to be indicators of human impact on climate and ecosystems (Wigley et al., 1998). This model has also been applied to studies of Global Warming Potential (GWP, Wuebbles, et al., 1995), and the Economic-Damage Index (EDI, Hammitt et al., 1996) concepts. http-climate.atmos.uiuc.edu/isam2/descript.html http-nacp.ornl.gov/mstmipdata/ Contacts: Atul Jain (jain1@illinois.edu) LPJ-wsl_Mstmip_Version1_Modeled_Method http-digitalcommons.unl.edu/cgi/viewcontent.cgi?article=1132&context=nasapub http-nacp.ornl.gov/mstmipdata/ Contacts: Benjamin Poulter (benjamin.poulter@lsce.ipsl.fr) Citations: 1.

Carbohydrates contain only carbon, hydrogen and oxygen atoms; prior to any oxidation or reduction, most have the empirical formula Cm(H2O)n. Compounds obtained from carbohydrates by substitution, etc., are known as carbohydrate derivatives and may contain other elements. Cyclitols are generally not regarded as carbohydrates.

If there is any potential ambiguity, an identifier should be added, including the system to which it belongs. "contributor" is an OWL "Annotation property" that names the person contributing the content, so s/he can be contacted, especially during development. definition_Source Schildhauer, orcid.org/0000-0003-0632-7576 "definitionSource" is the Annotation property that can be used to provide the reference source or Authority for the "definition" (of interest), as an ISBN,DOI, bibliographic citation, etc. to the source of the "definition" contained in an associated "definition" Annotation property that is attached (annotated) to the concept. Ideally a definition Source is structured in a well-known and accepted format, that provides an unambiguous pointer to a source reference, but often even some accurate indication of a reference source is better than nothing at all. Schildhauer, pers comm, 05Feb2015, orcid.org/0000-0003-0632-7576 description "description" is an OWL "Annotation property" that contains a a more verbose, less prescriptive natural language explication of the concept to which it is attached (or applied, or annotated) in contrast to a "definition" Annotation property.

Ideally a descriptionSource is structured in a well-known and accepted format, that provides an unambiguous pointer to a source reference, but often even some accurate indication of a reference source is better than nothing at all. As description Annotation properties are often not as rigorous, and hence looser and more verbose than definition Annotation properties, these fields may be more readily used for informal pedagogical advice and direction rather than being proscriptive has_Exact_Synonym The DataONE carbon flux ontology uses synonyms for terms that may not be well defined. But we know that they are used, and refer to an owl class. I.e., a concept can have a synonym, but a concept should not be a synonym. ad hoc has_Related_Synonym Margaret O'Brien, 2015-03-18 mobb has_Exact_Synonym is an OWL annotation property that holds an alternate name or lexical variant of an owl class. We are not planning to use has_Broad_Synonym or has_Narrow_Synonym at this time. although other ontologies do. the concepts of "broad" and "narrow" imply relationships that could be better described with the class hierarchy. example_Of_Usage O'Brien, pers comm, 2015-02-19 "example_Of_Usage" is an OWL annotation property to record examples of how the concept or property should be used. "example_Of_Usage" is for providing examples. It should contain actual sample strings for the resource it applies to. longer, text descriptions of good practice for the resource belong in the "description" annotation. O'Brien, pers comm, 2015-02-19 Margaret O'Brien, orcid.org/0000-0002-1693-8322 has_Related_Synonym has_Related_Synonym is an owl annotation property to hold a term that is not an owl class, but is a primary term found in the literature but is not necessarily correct. The DataONE carbon flux ontology uses synonyms for terms that may not be well defined. But we know that they are used, and refer to an owl class.

In the DataONe Carbon Flux ontology, we use rdfs:label for a human-readable version of the resource's name, but adhere to a particular pattern. Our goal is that content of rdfs:label are not broken into individual terms arbitrarily. 1. Our practice is to separate individual words in the rdfs:label with underscores, but maintain capitalization consistent with the conventions of the resources type (e.g., camel case for properties, capitalized words for classes, capitalized abbreviations and acronyms). 2. include namespace in the label, if resource is imported. See example_Of_Usage, presentation_Label O'Brien, 2015-02-19 rdfs:label is an instance of rdf:Property that may be used to provide a human-readable version of a resource's name
