Experiment Aim and Procedure

Aim: To find a correlation between the number and size of barnacles in two distinct areas and, the salinity of ocean around the barnacles at the different tides in order to discover barnacle thriving conditions.

Procedure:

Find two similar areas along coast in terms of rock surfaces. One near the Spiritual center and one near the maintenance docks.
On a sunny day, preferably after a spell of no rain. Our group of four will split into two groups so that we can take measurements at the locations simultaneously.

Upon arrival at area, the procedure consists of the same steps:
  1. Arrive ten minutes before predicted low tide and use Low Tide Finder to find lowest water level possible
  2. Use tide tables to find the distance above low tide to high tide
  3. Use measuring tape and rope to mark off area, from the surface of the water at low tide to the surface of the water at high tide
  4. Measure all barnacles in respective area using transect grids with a width of approximately 20cm
  5. At lowest tide take a sample of water to measure salinity content later
  6. At highest tide take a sample to measure salinity content later
  7. At lowest tide take a measure of temperature
  8. At highest tide take a measure of temperature
  9. In the lab combine/compile data and use salinity meter to find salinity content of water samples (four in total)

Apparatuses

These are the Apparatuses we invented and are using.
Low Tide Finder: Thrown into water before low tide, anchor keeps it from moving, sliding component moved down with the surface of the water or tide until it goes down no farther.
Anchor: Used to stop any current from moving the low tide finder.
Sliding Component: Slides up and down rope to find the lowest possible tide.
Ropes: Used to mark areas under observation.
Water Containers: Used to take water sample from one of the two areas.
Water Containers: Used to take water sample from one of the two areas.
Measuring Tapes: Used to measure dimensions of area under observation and the distance between low and high tide.
Temperature Probe: Used to measure temperature.
