Plankton Math

Try your hand at figuring out how many of a certain species of plankton we found in cubic meters of water from our tow the other night!  Use the attached directions and formulas to compute the numbers we observed.  I will mail the first person to correctly respond with all three plankton values a cup we shrank down during the 2,000 meter Multi-core!

Our supplied values:

Length of tow (pre-calculated) from boat: 57.906 meters

Diameter of plankton net: 30.5 cm

Sample bottle size: 250mL

 Number of drops analyzed: 50

Number of Copepods observed: 50

Number of Echinoderm larvae observed: 19
