    "descript": "This portion of the data release contains information on vibracores that were collected by the U.S. Geological Survey in Pololu Valley, Island of Hawai'i in 2014. Five sites were cored in order to describe wetland stratigraphy and to identify potential tsunami deposits. These vibracores contain mud, peat, fluvial sands, and marine volcanic sands, reflecting deposition in a variety of coastal environments. Two (2) pdf files (VC1.pdf, VC2.pdf) describe vibracores that were split, imaged by a line-scanner camera, scanned to generate computed tomagraphic (CT) images, and visually described. A detailed description of the upper 150 cm of VC1 using the Troels-Smith sediment classification scheme (Troels-Smith, 1955; Nelson, 2015) is included in VC1.pdf. Another pdf file (Pololu_cores_legend.pdf) contains a core-log legend. Cores VC3, VC4, and VC5 were collected using shorter sections (less than 200 cm) of extra pipe in order to capture the sand layer from the 1946 Aleutian tsunami that inundated the valley (Chague-Goff et al., 2012) and have not been photographed or CT-scanned. A comma-delimited text file (Pololu_sand_thickness.csv) includes tabulated information on the depth and thickness of sand beds P1, P2, and P3. In addition, a shapefile (pololu_vibracores_2014_locations.shp) provides sample locations of vibracores.",

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."

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)."

Assessments include evaluations of present ecological or economic values of substrate distributions, drivers of substrate change, and functions of substrates. Predictions are the results of models or projections of future substrate distributions, values, or ecological impacts, including predicted substrate changes due to natural and human forces including erosion, accretion, sea-level change, extraction, trawling, or other factors; and they are the results of scenario-based models of substrate changes on ecological or economic values under different management strategies or other human alterations."
