Wecoma at Dusk
The April cruise was a great success! The weather was perfect, and we stayed ahead of schedule for nearly the entire trip.
The cruise plan involved four transects consisting of over 40 casts, about 20 of which involved water sampling.
The whole team worked in three shifts, 8 hours off and 4 hours on, to operate the CTD and process the collected water samples.

The first day required retrieval of an OrCOOS buoy and deployment of a mooring. Several team members then disembarked, and the rest of us prepared for our work shifts. Soon after, we discovered a stowaway octopus!

The team is thrilled about the number and quality of the samples obtained. For example, as expected, we observed obvious differences in the coloration of the Sterivex filters between surface and bottom water samples as well as differences between sites.

We also managed to experiment with the a new data processing and telemetry pipeline. The network connectivity was surprisingly strong even at times over 20 miles offshore. The data collected from the Wecoma (ADCP, Flow-through CTD, and CTD casts) were parsed and processed in real time using a new CMOP Ocean Appliance, a hardware and software platform providing the same capabilities as the CMOP servers, but scaled down to a single desktop machine. When the network was in range, new and changed data were automatically pushed back to the servers.
