    "descript": "This data release contains information on computed tomography (CT) images of a vibracore that was collected by the U.S. Geological Survey in 2019. A site next to the San Lorenzo River in Henry Cowell Redwoods State Park, California, was cored to understand the history of recent vertical incision and floodplain abandonment. The core was split into 3 segments after collection. Each segment was scanned using a Geotek Rotating X-ray CT (RXCT) System and CT reconstruction was performed using Geotek reconstruction software. Geotek CT_Quickview software was used to select a representative down-core orthogonal slice from each core segment and the Geotek AddRuler software was used to display core-lengths in each image. The downcore orthogonal slice CT images of each core segment are included as three separate TIFF files. Each TIFF file is accompanied by a software-proprietary XML file  that contains the x-ray scanning configuration and settings in addition to dimensional data of the TIFF images.",

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."

Distributions are detailed topographic and bathymetric maps, geolocated photographs, or sea-floor descriptions; Distributions includes maps that interpret observations to categorize areas on the basis of geoform types such as those in CMECS. Assessment types include evaluations of ecological or human use value and can include models that project environmental or economic effects of erosion, climate change, dredging, and other stressors. Predictions are the results of models or projections of future distributions, values, or ecological impacts of physical habitats, including predicted changes due to natural and human forces; they are also from scenario-based models of resource losses, gains, or impacts on ecological or economic values under different management strategies (for example, mining, removal, relocation, or the building of structures)."
