Service Description: <DIV STYLE="text-align:Left;font-size:12pt">Gravel makes up seafloor sediments with larger grain sizes than those considered to be sand (>2 mm to 4 mm). Gravel types and percentages can indicate geologic histories as well as types of communities likely to be present. Gravel can vary in carbonate content and form a more stable substrate allowing organisms to attach and grow into diverse ecological communities including several types of biogenic habitats such as some kelp forests and algal meadows, as well as rhodolith beds, bryozoan and sponge gardens, especially in areas of rhodolith and shell-derived gravel, and even sea pens in areas of finer gravel. The percent gravel layers for the region were developed from >30,000 raw sediment sample data and compiled (Jenkins et al. 1997), then imported into ArcGIS and interpolated using Inverse Distance Weighting (Bostock et al., 2019).
