So what did we accomplish?
From the CTD-Divers attached to mooring cable 1 (see Part 3) we obtained data for temperature, pressure, and salinity at five different points above the ocean floor. We found that the pressure plots were strongly influenced by the tides. We applied a filter to the data to remove the tidal signal (Figure 1) so that we could see how much of the pressure variation was due to other phenomena. Examination of the temperature plots (Figure 2) showed us the predicted seasonal and diurnal variations at all depths but also provided insight into some phenomena while raising questions about others. The conductivity plots (Figure 3), which provide salinity data, were a bit disappointing. Biofouling of the sensors prevented them from providing much information past the first month of deployment.
For me, the really interesting part is knowing that this data will be assimilated along with data from other sources, and used by other Deep-C researchers. Dr. Nico Wienders and Dr. Allan Clark are already talking about how this data will be used and reported at the upcoming Deep-C All-Hands Meeting this fall. It’s a fine feeling for me to leave knowing I was a part of the overall effort.
