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."/><bt><term thcode="23" 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."/><term thcode="23" 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."/><term thcode="23" code="1" name="Data Categories for Marine Planning" scope="Categories indicating the breadth of information types required for ocean planning from a national, multidisciplinary perspective.

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."/><term thcode="23" code="10" name="Natural Gas Resources" parent="8" scope="Stocks of naturally formed hydrocarbon gases, which are usually associated with petroleum fields or gas hydrate formations. Distributions are geologic maps, models, and other observations that indicate locations and volumes of underground stocks. Assessments evaluate locations, methods, and profitability of gas extraction and transportation; environmental impacts; and (or) other interactions with other uses. Predictions are the results of models or projections of future gas reserves based on projected extraction, or they are predicted changes in profitability and risk due to economic, regulatory, technological, and environmental changes."/><term thcode="23" code="13" name="Ocean Currents" parent="8" scope="Relatively constant directional flows of large water masses, which can be driven by a variety of dynamic forces. Distributions are observations of current speed and flow volume, as a function of location, time, and depth, and they include maps of ocean current climatology generated from oceanographic and weather observations, analysis of other driving forces, hydrodynamic theory, and numerical models. Assessments evaluate technology, locations, and profitability for using ocean currents to generate energy; they also evaluate effects of currents on biological resources and on other uses such as transportation or the extraction of resources.
