{"thcode":23,"term":{"code":14,"name":"Geothermal Resources","parent":8,"scope":"Includes temperature differences related to the Earth's internal heat, commonly observed as springs or vents discharging hot water or steam, or through geothermal wells positioned to extract heat. Distributions are direct observations of the temperature and flow volume of springs, vents, or deep-lying heat sources, as well as geologic and hydraulic models that estimate the location, temperature, and flow rate of hot water. Assessments evaluate geothermal energy potential, risks, and effects on other resources and uses. Predictions are the results of models or projections of future energy potential, risks, and effects; these data include predicted changes due to economic, regulatory, technological, and environmental changes."},"uf":[],"bt":[{"code":8,"name":"Energy Resources","parent":7,"scope":"Natural features that provide a capacity to do work through combustion, movement, radiation, or heat; these resources include oil, natural gas, coal, wind, sun, currents, tides, and natural heat gradients. Distributions are recorded observations, maps, or models of specified resources at known locations, in some cases as a function of season or other temporal scales. Assessments are evaluations of the economic or ecological value associated with the resources or of the difficulty, environmental effects, or sustainability of energy extraction and production. Some assessments can appropriately be included in the Energy Resources category and also in related Living Resources or Uses categories. Predictions are the results of models or projections of future distributions, values, or impacts of energy resources; these data include forecasts of changes due to natural and human processes, such as resource losses or gains under different rates of resource extraction, effects of climate change, and so on."},{"code":7,"name":"Nonliving Resources","parent":6,"scope":"Data are about chemical, physical, or geological features that are of use or importance to humans or ecologies."},{"code":6,"name":"Data Content Subjects","parent":1,"scope":"Environmental characteristics and processes as well as human activities that use, rely on, or impact those features."},{"code":1,"name":"Data Categories for Marine Planning","parent":null,"scope":"Categories indicating the breadth of information types required for ocean planning from a national, multidisciplinary perspective.
