The carbonate percentage indicates biological material produced both in the water column by plankton and on the seafloor by a variety of benthic species that make carbonate-containing shells or other body parts. Shell debris can also influence water characteristics such as dissolved carbonate minerals, alkalinity, oxidation of solid phase sulfides, and carbonic acid production and larger grains may form the basis for several types of key biogenic habitats such as rhodolith beds, bryozoan and sponge gardens. The percent carbonate 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).
