There is lots of jargon in the following post, but I will get around to explaining it all in the near future.

Elizabeth and I collected samples from 4 depths at stations E&B on the 4th and 6th (16 samples total). To collect the samples, we put the water into dark bottles and brought them to the lab for filtering. I’ll explain this a bit more in the future, but we filtered for HPLC and total Chlorophyll both days. On Monday, we also collected samples (DOC, DNA, Flow Cytometry) for Hugh Ducklow’s group at each of our sampling depths. We also spent a day and completed the standard curve for the lab fluorometer, so we will begin processing total chlorophyll samples this coming week. The technician here is just about finished getting the HPLC set up, so we expect to run our HPLC standards this week, and process samples the following week. We also made up a batch of Alcian Blue for TEP filtering for future surface samples (triplicate filtering needed, so only surface will be used for TEP). We used the radiometer on the 6th but not the 4th. The 4th, we just sampled based on the structure of the water column seen with the CTD cast. On the 6th, we also sampled based on CTD data, but we sent the radiometer down with the bottles so that we have the %irradiance at each collection depth. In particular, we ended up sampling at the 100%, 56%, 18%, and 6% irradiance levels. It is a bit time intensive because we only have one submersible radiometer, so we send down the radiometer and GoFlow together, pull them up and then do another cast with another bottle.
