  1. How are fouling organisms affected by tidal action? GROUP 21 Owen Bescherer, Hannah Taylor, Sam Most, Teresa Willander, Kylie Michaels

  2. What are fouling organisms? • Various organisms that live on wetted surfaces like barnacles, algae or seaweeds. • Live by affixing themselves to a surface that is regularly or permanently submerged. • Feed off the plankton and scraps that float by. • If left unchecked fouling organisms can cause problems by eroding and jeopardizing the integrity of structures. ]\

  3. Site 1a

  4. Site 1a: fouling organisms h Population Density (organisms/opening) Higher-up organisms seem healthier, all below are dried up.

  5. Site 1b: Opposite Side

  6. Site 1b: fouling organisms Population Density (organisms/opening) Organisms on bottom of pylon seem dead.

  7. Site 2a

  8. Site 2a: fouling organisms Population Density (organisms/opening) At the bottom of this pylon, green seaweed was found among the fouling organisms. Also, the organisms appeared noticeably larger than those at the previous pylon.

  9. Site 2b: Opposite Side

  10. Site 2b: fouling organisms Population Density (organisms/opening) Similarly to site 2a, it’s opposite side had larger and healthier-looking organisms, accompanied by seaweed.

  11. Graphs

  12. Conclusions • In general, there were more organisms found at the top of the pylons. • Dissolved oxygen and salinity remained relatively constant throughout the different sites, as did temperature. • The third site we examined, pylon 2a, had more organisms on the lower part of the pylon. This was different from the rest of our data, with no visible correlation between the factors we tested. • Our data was inconclusive on the relation between salinity, DO, temp. and amount of fouling organisms.
