Science Objectives | |
Sievert/Taylor/Rich: Knowledge of the in situ metabolism of microorganisms carrying out CO2-fixation at deep-sea hydrothermal vents is very limited. Particularly lacking are studies measuring rates of autotrophic carbon fixation in situ, which is a measurement ultimately needed to constrain production in these ecosystems. Although recent data suggests that nitrate reduction either to N2 (denitrification) or to NH4+ (dissimilatory reduction of nitrate to ammonium, DNRA) might be responsible for a significant fraction of chemoautotrophic production, NO3--reduction rates have never been measured in situ at hydrothermal vents. We hypothesize that chemoautrophic growth is strongly coupled to nitrate respiration in vent microbial communities. As part of this cruise, we are going to deploy and test a newly developed robotic micro-laboratory, the Vent-Time Series Submersible Incubation Device (Vent-TSSID) for measuring rates of relevant metabolic processes at hydrothermal vents at both in situ pressures and temperatures. Scott and Girguis: The relative importance of the two carbon fixation pathways (CBB, rTCA) in Riftia is impossible to infer from the existing data. Bulk stable carbon isotopic compositions, and the presence and activities of enzymes allied to rTCA and CBB in Riftia symbionts, do not definitively answer whether one or both pathways are operational in a single individual, and the contribution of each pathway to net carbon fixation. The objective of this study is to clarify whether the activity of these pathways in Riftia are regulated by environmental conditions (e.g., the relative abundance of redox substrates), internal heterogeneity, or whether both pathways operate simultaneously. | |
Science Activities | |
Sievert/Taylor/Rich: Our component of the cruise has 12 dives with DSV Alvin, to allow time for deployment and collection of experiments and for sampling of discrete vents along the axis of the 9°46’N to 9°53’N segment of the East Pacific Rise (EPR). We will focus our activities at Crab Spa, a diffuse flow vent site near Tica, and deploy experiments and sampling equipment, including the Vent-TSSID and a large volume pump (LVP). During the course of the cruise we will perform several deployments of the Vent-TSSID, as well as collect biomass from fluids and biofilms (deployment/recover experimental microbial colonizers) by utilizing a the LVP. Both the Vent-TSSID and the LVP will be deployed as an elevator. It is planned to deploy the instruments and bring them close to the deployment site the night before a dive, and then to position the instruments at the site with Alvin the next day. Alvin will be releasing the instrument either on the same dive or any subsequent dive, after which the instrument will be picked up at the surface. Furthermore, we will carry out additional opportunistic sampling of other diffuse-flow vents. Fluid samples for chemical analyses will be collected at each deployment site using isobaric gas-tight samplers, which will also be used to sample fluids from the focus site for the shipboard incubations. Finally, we will deploy/recover experimental microbial colonizers to collect microbial biofilms, as well as collect Riftia for subsequent ‘omic analyses. We will also perform several water casts at night, using the CTD/Niskin rosette on board Atlantis. Scott and Girguis: To address our objectives, it is critical for us to get freshly collected Riftia tubeworms that have been placed in a thermally insulated biobox and sent to the surface as soon after collection as possible (elevators would be fine as long as they were retrieved as soon as they surfaced). Collected tubeworms would be incubated in high-pressure aquaria in the Girguis lab's pressure van for respirometry experiments. After they reach steady-state, they will be subsampled for tissues, enzyme assays, and symbiont preparations (we will need some bench space in one of the ship's labs). Symbiont metabolism will be interrogated via 14C-labelling experiments (we will need to use a radioisotope van and have submitted our radioactive materials use request to WHOI). | |

| Please give a brief description of the equipment, its intended purpose, the cruise # it was last used on if any and its deployment method.
Sievert/Taylor/Rich: We are going to use a a number of instruments, msot of which have been used with Alvin: 1. We will be using Jeff Seewald's isobaric samplers, which have been used frequently with Alvin 2. We will be using chemical in situ sensors developed by Nadine LeBris, these are self-contained units that have been frequently used with Alvin (last time on AT15-38) 3. A McLane in situ large volume pump is going to be deployed as an elevator. Alvin will need to move the pump to the deployment site and also release it after filtration is finished (6-8 hours) 4. Vent-TSSID: This is a newly devleoped isntrument that has not yet been used with Alvin. The pressure senstive components will be pressure tested according to Alvin specificications. Fred Thwaites who is engeering the isntruemnt has been in touch with Alvin group. Girguis/Scott: We may possibly be gringing in situ blenders to preserve tubeworms on the seafloor. They are not pressurized. | |||||||
