This will need to be mounted on basket with on/off control from inside sub. We used this same set-up with great success on last leg Small Niskins, rack or sponson mount (Cavanaugh) Up to 6 elevator deployments w/acoustic release (reinforced for 250# in-air weight) Program-Provided See details below for: Science Tools: Sipper (GO model 1014 rosette, RoseSoft v1.3 windows program & manual to ship on 10/30 dbf) "Mosquito" thermocouple Chimney sampler Cary bio-box RNAlater "Fries" to deploy/recover (Cavanaugh) "Shank" sampler Shipboard Transponder nav - may be needed for 13N Equipment/Nav: SEANET Other Requirements: Isotope van Night work anticipated (CTD) Hazardous material will be aboard All waste will be removed in San Diego at termination of leg. This include hazardous waste and radioactive waste. Notes: SIPPER: The SIPPER unit is a microwater sampler that requires a 50 v DC power source and RS232 communication. In-water weight of 21lbs/air 41lbs. 50v power out of sphere from a Vicor DC-DCpower supply (26v input). RS232 comunication is used for control of the unit and input of data. The sipper has been deployed on 7 past cruises very successfully and is well known by the Alvin group. Attached to the SIPPER is a separate thermocouple unit that requires RS232 communication and 12 volt power. This unit was designed and built by Lane Abrams at WHOI and needs to be logged in the Alvin data system and displayed on the video data overlay. Previously the serial port replaced the Alvin ICL serial port since the data and display functions do not require any changes using this port. The SIPPER unit has the ability to take 12 independent water samples. This unit is positioned at the rear of the basket but in view of the pilot. The water samples are taken with continuous temperature measurements through 2 tubes that terminate in a "T" handled wand unit. The thermocouple unit interfaces with the wand and is cabled back to a small communication bottle positioned to the rear of the basket. We anticipate that this unit will go down on all dives. An addition to the SIPPER will be a small water pump (Sea-Bird) that will require 15 volts output from the sub (in water wt. = < 3 lbs). This is one of two seabird pumps we will have on the sub (see RNA sampling below). We have built a small converter that will be wired inside the sub to take 26v and step it down to 15v. This converter also will be equipped with an independent switch that will be used to turn the unit on and off. An amp meter in this control box serves to inform the user if the unit is operational and pumping. "Mosquito" thermocouple (in water wt. = < 1 lbs): We intend on doing long term deployment of the mosquito probe. This unit has been used by the Alvin group in the past (Nature paper). The unit consists of a DSPL HOBO with only a 8" probe. Our intention is to make it neutrally buoyant with syntactic foam and fly it free line into an hot Alvinella tube. We intend on 3-24 hour deployments. Chimney Sampling (in water wt. = anticipate 10 lbs each): We have designed several sampler devices that we will be using on this cruise to take discrete sulfide samples. The samplers are currently being built at Arizona State University for deployment in Oct. One unit will have the ability to sample and contain small chimneys. The other will be positioned on a orifice so that the emerging fluid is channeled through several small chambers that will house various minerals. Both units will be deployed and recovered (placed into large biobox) by the submersible. Other equipment: The Cary bio-box's have been built to contain and isolate the chimney samples/Alvinella from the surrounding water. A small unit (12"X12"X12") will be deployed on most dives. The larger unit (12"12"X36") be used exclusively when larger samples are to be collected. RNAlater worm fixation rig (in water wt. = anticipate < 2 lbs): This unit is designed to retain Alvinella and small Riftia for RNA analysis. The system (3 x 8" dia sample vessels) are contained within a rectangular milkcrate. An additional 8'X18" cylinder containing the fixation fluid will be place below the sphere at the base of the basket. The fixation fluid will be pumped, using an Alvin pelagic pump ) into each of the individual sample vessels on demand. Each sample vessel will be held isolated from the others by a simple "T" handle valve assembly. Once a sample is placed into the sample vessel a plunger will be inserted into the vessel to seal the chamber. Once sealed preservation fluid will be pumped in the chamber until full. On the bottom animals are collected using the slurp pump. The pump for the fixation fluid will be controlled by an additional switched wired into the SIPPER control panel. SeaNet: We will have a educational/outreach effort going on during the cruise. This NSF funded project (inc. one Alvin dive!) will bean up-scaled version of our Extreme 2003 effort we had in Nov 2003. Here we intend to include over 520 schools US and internationally. The success of Extreme 2003 can be attributed to many but at the top of that list was the Alvin group and the crew of the Atlantis. We will need access to FTP capabilities on Seanet similar to those in place for Dive and Discover that will allow daily transmission of Mpegs, and text to our home FTP site. We request the SSSG be current with these technologies and able to assist us in making this happen. We will also need the Mac to be G4s. Elevator Use (in water wt. = anticipate < 5 lbs, water sample out of water wt. < 250lbs): We are intending on deploying the elevator up to 6 times for equipment deployment/recovery and water sampling. For the water sampling we are intending of collecting 50 liters of water on a regular basis. We are currently designing a water collection pump assembly that will be mounted to the elevator. We will deploy the elevator and locate and position near vent on the bottom. Our intention is to have a pump hose that will be pulled from a housing to the desired position on a chimney. The pump will turned on via a magnetic switch. Bags will be filled with the vent water until full. The switch will be turned off by placing the magnet back on the switch. The hose will be secured and the unit sent to the surface. This unit was used last year on Extreme 2003 by Dr. Eric Wommack. It is essential that we be able to locate the elevator quickly on the sea floor. Every effort shouyd be made to make sure that all sensor equipment on the sub is avaliable and working to allow us to minimize the use of bottom time to find the elevator.
