Location:off Fiesta and Long Keys
Chief Scientist Bob has located the inner edge of the eddy which are small scale circular currents that penetrate 100-200 m in these waters. These eddies are important components of retaining the larvae in the Florida Keys and where we are focusing our sampling in these final cruise days. The current data shows a reversal of water flow here where we are sampling. We ran out of filter paper so have filtered our last chlorophyll samples this morning, however, we still deploy the CTD at alternate stations to collect the physical oceanographic data. We are continuing the MOCNESS plankton sampling but the preserving alcohol supply has run low. So we are using the remaining alcohol judiciously.
Capt. Sean pointed out some of the interesting first vessels of the day. An enormous cruise ship went by doing ~19 knots then a "Row-Row", a container ship, that quickly empties the cargo containers as they roll off, passed by in the distance traveling at 16.5 knots. The R/V Walton Smith goes ~10 knots when the bottom is clean and it's running well.
This afternoon, I returned some of Bob's publications that were really helpful to read and gave him an ARMADA hat as thanks for a fabulous research experience. Zoe has the picture to prove it.
