Distributions are records of currents, physical properties, or biogeochemical water properties, often based on shipboard surveys or coastal monitoring programs, and maps of currents or water property climatology, which indicate the expected locations of features under present conditions or apply a classification structure like that of CMECS. Assessments are data that provide information about the ecological or economic values, impacts, drivers, connections, or functions of water column features in their present distributions. Predictions are the results of models projecting future changes to currents or other persistent oceanographic features (for example, clines, stratification, connectivity, linkages, and zones of separation) due to climate change, ice-cap melt, and changing freshwater inputs; models predicting the ecological or economic impacts of these changes; and scenario-testing models comparing ecological or economic outcomes of different management actions."/><bt><term thcode="23" code="20" name="Physical/Chemical Features" parent="7" scope="Geological, chemical, or hydrodynamic features that are ecologically important or influence patterns of human uses of the ocean. Examples include seamounts, persistent upwelling zones, areas of low dissolved oxygen, and areas of reduced pH. Distributions are recorded observations of parameters and features, often as a function of time as well as place, also including maps and three-dimensional predictions of distributions based on combinations of observations and theory. Distributions of physical and chemical features (for example, physical habitat, substrate, or bathymetry) are often used as data to support habitat-biota models. Assessments provide information about the value, impact, drivers, connections, or functions of a feature in its present distributions, or they evaluate the effects of physical/chemical features on ecology or suitability for use. Assessments can include climate change models that project environmental effects of climate change and acidification. Larger assessments that combine physical/chemical features with other Resources and Uses categories can appropriately be included here and also in the other related Resources or Uses categories. Predictions are the results of models or projections of future distributions, values, or impacts, which include anticipated changes produced by natural and human processes, and they are also the results of scenario-testing models for comparing outcomes of different management actions."/><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.
