Science objectives

The University of Minnesota research group has the following objectives:
1. Hydrothermal vent fluid sampling at Axial caldera and MEF. The vent sampling will involve direct acquisitoin of samples using Alvin, but also deployment of time series sampling by remote operation.
2. Chemical sensor deployments will take place in association with vent fluid sampling

The primary goal of the Crone, Mittelstaedt, Fornari group is to deploy and test two new camera systems designed to acquire video imagery of hydrothermal venting.  Fornari also plans to bring out his MISO time lapse camera to take photos of Alvin working on the bottom as time is available and in a not-to-interfere basis with the science programs.  This would be deployed on an elevator similar to what was done in the Gulf of Mexico on the SVC.

The primary goal of the Kinsey, Crone, Mittelstaedt group is to use the AUV sentry to measure the volume and heat flux of hydrothermal fluid passing through a rectangular volume centered around the Ashes and MEF hydrothermal sites.

The Tivey/Farr second leg will be focused on CORK optical communications.  We currently have underwater optical modems installed at two seafloor CORK sites: at 857D in Middle Valley and 1025C on Endeavor Ridge flank.  The objectives of the Tivey/Farr cruise program are to download CORK data using the optical modems, recover the CORK optical modems, and test a new generation of optical modem (3G) using Alvin, Sentry and lowered CTD platforms.

Science Activities

To fulfill UM objectives, we will deploy sensor and samplers at sites of high temperature venting, but also at sites of diffuse flow venting. Vent sites are located at ASHES at Axial caldera, but we will also investgiate sites at MEF (Main Endeavour Field), and possilbe MOTHRA vents near MEF on Endeavour segment, JDF. Vent fluid samples will be processed on board ship
Chemical sensor calibartion efforts will also take place shipboard, before and after seafloor deployment. The UM group will be heavily involved with chemical work while onboard.

The Crone, Mittelstaedt, and Fornari group will use Alvin to perform site surveys, test and deploy two stand-alone camera systems, take temperature measurements at diffuse and focused hydrothermal vents, deploy temperature sensors, and perform minor mapping surveys using Alvin if time permits. We would also like to have Alvin be capable of acquiring near-bottom multibeam data using the RESON multibeam in order to test and prove that system and to establish the data quality and processing so that Alvin can offer this capability to future users - this is a secondary but important objective.

To accomplish our goals, the Kinsey, Crone, and Mittelstaedt group will conduct AUV Sentry dives during night operations between Alvin dives.  These Sentry dives will include mapping, photo surveys, and flying a series of repeated surveys around and within a rectangular box located over each vent field.

The Tivey/Farr CORK optical communications leg (Jul 27-Aug 6) will undertake the following operations at the two seafloor CORK sites (857D and 1025C).
At 1025C:
* download data using shipbased CTD lowered optical modem
* test Sentry optical modem using CTD lowered optical modem.
* Alvin Dive to recover old CORK optical modem, download CORK data
At 857D:
* download data using shipbased CTD lowered optical modem
* Alvin dive to deploy new 3G optical modem, recover old CORK optical modem, download CORK data.
* Sentry dive to test new 3G optical modem
* Alvin dive to recover new 3G optical modem and then a geophysical and geological exploration of 857D to 858G Dead Dog hydrothermal field.
* Sentry dive geophysical survey of 857D to 858G Dead Dog hydrothermal field

We will be attaching a set (~5) of SensorBots to the CTD wire for testing of optical communications between the sensors during one of the LADCP deployments. These sensors should not interfere with any operations of the CTD system but will need to be attached as the cage descends.
