That's another good question.
We're trying to be as comprehensive as possible, because we recognize some species occur in the spring, some occur in the summer, and some occur perhaps in late fall.
What we're doing with our research sampling is we're going to each of those 16 ports that I mentioned twice per year: once in late spring and once in midsummer. Again, it's getting kind of complicated, but when we have the DNA sequence of all these organisms, we use a technique called PCR, which creates many copies of each one of them. Then we can put them through the sequencer that I mentioned, determining the order of the basis in that sausage chain. From that, you can reconstruct for each one of between 1.5 and 1.7 million DNA sequences, and you can go back and cross-reference each one of them against an online database to determine what species you have.
