Influence of Sedimentary and Seagrass Microbial Communities on Shallow-Water Benthic Optical Properties-Data Mining
Abstract
Lipid-based microbial biomass varied greater than 10-fold among sediment archetypes collected at LSI during field campaigns. Seagrass epiphyte loads, determined by measuring their lipid biomass, increased non-linearly with leaf age. The highest epiphyte loads, on eelgrass from Monterey Bay, absorbed 60% of incident light in peak chlorophyll absorption bands and reduced modeled photosynthesis by 49%. In the course of this research, we have found large, refractive, rhomboidal crystals in turtle grass from the Bahamas, Florida, and Texas. At all collection sites, crystals were present in leaves of all ages and in most, but not all, epidermal cells.
