You are a researcher on the that has takien water samples in quadruplicate during the winter. Once you return to your lab, you start to process one water sample in each of your replicates for each station you stopped at to be sure your analytical methods are valid. You notice that the samples have a very high degree of variation in salinity and other strange things. The % chloride ion is at 40% of the dissolved solids and the pH of the sea water is fluctuating between 7.0 and 9.2. What explanations can you offer for this sort of phenomena? What are your supporting arguments and what should you do next?
