Description: Light attenuation is a critical parameter governing the ecological function of shallow estuaries. We quantified light attenuation and sediment resuspension in three seagrass meadows in Barnegat Bay, New Jersey, by sequentially deploying instrumentation measuring photosynthetically active radiation, chlorophyll-a (chl-a) fluorescence, dissolved organic matter fluorescence (fDOM; a proxy for colored DOM absorbance), turbidity, pressure, and water velocity at 10 min intervals over three week periods at each site. The data show the relative importance of physical and biogeochemical processes on light attenuation.
