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. Predictions are the results of models or projections of future currents, energy potential, effects, and risks; these data include predicted changes due to economic, regulatory, technological, and environmental changes."/><bt><term thcode="23" 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."/><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.
