Science objectives
there are three groups coming out on this cruise. for the Sylvan group, the objectives are to study the transition in mineralogy and microbiology as active hydrothermal sulfides transition to inactive. we will do this through a combination of collecting exposure experiments set out in March 2019, currently sitting judst outside the axial valley on bare basement ~75 m from Bio9 or down near Q vent as well as collecting already inactive sulfides for comparison to the exposure experiments. we will also collect seafloor basalts for microbiology analysis. for the Mullineaux group, she will be collecting larval experiments previously deployed as part of an ongoing experiment by her lab and potentially collecting other animals as well. for the Fornari group, they will be using Sentry at night to map the region down to 9.45N.Science Activities
12 Alvin dives are planned. we will be collecting inactive vent sulfides, seafloor exposure chambers for both Mullineaux and Sylvan - different experiments but for both picking up previously deployed experiments), collevcting seafloor basalts (on a few dives, this is a secondary objective), potentially collecting Major samples of hot fluids and possibly diffuse fluids when swapping out temperature loggers (Fornari), and using Sentry in the evenings.Pre-cruise planning meeting: Teleconference
visit if necessary but schedule may not permit. Meg Tivey is co-PI on my grant and can help locally as needed. Fornari can't help himself and will help, and Mullineaux is also local and can help as neededMedia personnel on board: Video, Writer
i hope to bring an outreach specialist, Rebecca Fowler (http://www.rebeccafowler.org/) but funds need to be secured to confirm

Critical CTD Sensors: CTD use not likely on this cruise, but checking off here so that it is available if needed
CTD-Related Equipment
Lowered Acoustic Doppler Current Profiler (LADCP)Sample Storage
Climate Controlled Walk-inFreezer -70°C 25 cu. ft.
Refrigerator 8.6 cu. ft.
Scientific Walk-in Freezer
Scientific Walk-in Refrigerator
Freezer -70°C 3.2 cu. ft. ea.
Storage Notes: will need refrigerated walk-in, -70C freezer (as much space as possible), -20C freezer, and a standing refrigerator in the main lab. potentially the walk-in can serve as a refrigerator, but would be best to have walk-in refigerator AND a standard, kitchen-sized unit in the lab
Navigation
Will you be using Long Base Line (LBL) navigation? no
Will you be using Ultra-short baseline (USBL) navigation for other than Alvin operations? no
Navigation Notes: not sure what to write here, we need whatever is necessary for getting to the sites and using Alvin
Winch Notes: we will be using Sentry and deploying elevators, so the winches necessary for those deployments will be needed
Wire Notes: an ADCP from Andfreas Thurnherr will be deployed at the beginning of the dive series and i believe recovered at the end, not sure what wire use needs are for that but we will need to determine. this has been done previously with this system, so all needed info should be available
