Photosynthetic Response of Zostera marina (Eelgrass) to Insitu Manipulations of Light

Dennison WC, Mauzerall D, and Alberte RS ·

Photosynthetic responses of the temperate seagrass, Zostera marina L., were examined by manipulations of photon flux density in an eelgrass bed in Great Harbor, Woods Hole, MA during August 1981. Sun reflectors and light shading screens were placed at shallow (1.3 m) and deep (5.5 m) stations in the eelgrass bed to increase (+35% to +40%) and decrease (-55%) ambient photon flux densities.
