Summary
Transects were established and first monitored Lagoon-wide in the summer of 1994. All transects are monitored at least twice a year, summer and winter, corresponding roughly to times of maximum and minimum seagrass abundance, respectively. A subset of transects were selected to represent each segment of the Lagoon and are monitored on a monthly basis. The intent of this methodology is to sample (1) repeatedly at the same location along the same line, (2) quantitatively, (3) nondestructively, and (4) rapidly. For routine monitoring of transects, a standardized, non-destructive, quantitative technique has been adopted. Each transect consists of a marked line, roughly perpendicular to shore, extending from shore out to the deep edge of the seagrass bed. The transect line is marked with a series of PVC poles driven into the sediment at a maximum of 100m intervals (some transects have additional poles to mark shorter distances).
Parameters
% cover (0-100%), macro algae, species cover, epiphyte loading (1-5 scale), shoot counts, and canopy height (cm), water depth (cm)water clarity (color and turbidity, Photosynthetically Active Radiation (PAR))
