Results

The transect A was, as expected, the most impacted with an average coverage around 23% while the transect B has a slightly higher coverage, a bit less than 30%. Both of them were pretty far from the reference one, which went up to almost 90%.
Some species of seaweeds (Sargassum sp., Peyssonnelia sp., Padina pavonica) used as bioindicator, confirmed my data with their relative coverage.

TRANSECT R
LOW IMPACT


TRANSECT B
MEDIUM IMPACT


TRANSECT A
HIGH IMPACT


My results suggest that the diving is having a significant impact on the macroalgae coverage of the shipwreck, especially in areas subject to high levels of use, and that the coverage and biological composition of the substrate can be successfully used as an important and significant indicator of health status of the assemblages.
