Summary of Field Work: The proposed field component will include a 16 day cruise in 2013. We would prefer to use either Jason II or Alvin (following its current overhaul) with Sentry. We have planned for 2 dives at 5 different sites across the northern Gulf of Mexico. Effort will be distributed among sites depending on the success of each dive as well as weather and mechanical issues. At each site we will collect 10-15 Lophelia (a scleractinian coral) samples with water samples accompanying each sampling location within a site.

Small samples (10-12 polyps) from between 10 and 15 visually distinct L. pertusa colonies will be collected from each site into a series of separate collection chambers. The manipulator will grab a small segment of the colony and place it into a 9.5 cm diameter PVC tube (the standard larger diameter tube-core quiver) and seal the end of the tube with a weighted rubber stopper. Prior to launch, each of these chambers will be filled with a high-salt EDTA-based preservative (similar to RNALater), so that the corals will be preserved immediately upon collection. This collection technique was successfully employed during our cruise with Jason in 2009 and 2010 and Alvin in 2010 to collect numerous (up to 30 per species) discrete genetic samples with highly accurate positioning on the seafloor within a single dive. We will also collect L. pertusa samples into temperature-insulated bioboxes on the submersible for use in live animal experiments in the laboratory.

Water samples will be taken using a series of individually triggered 1.7 L Niskin bottles attached to a rack on the side of the submersible, and using a standard CTD-rosette. The custom Niskin rack consists of a hydraulically-actuated sliding bar on the top of the rack with a series of small PVC half-ovals that trigger each of the Niskin bottles individually as the hydraulic ram is extended. A similar Niskin rack (from Dr. Ian MacDonald) was used during our 2010 Jason cruise to collect bottom water samples and produced the data in Lunden et al (submitted). Two racks (10 bottles) will be placed on the submersible and one bottle fired each time we take a sample of L. pertusa. Additional water samples will be taken using the CTD rosette to characterize the carbonate chemistry of the water column. There is sufficient time built into the cruise schedule for at least one rosette cast per site. The rosette will be lowered to 5-10 m off the bottom and 2 bottles fired (in case one fails) at regular intervals between the maximum depth and the surface. There are 12 bottles in a standard rosette, providing water samples from 6 different depths at each location chosen (8 total CTD casts in the standard cruise plan).

We also have a well-established group of collaborators working in the Gulf of Mexico and beyond and will invite other research groups to participate in the cruise and plan on sharing samples and bottom time to the greatest degree possible. We would also be willing to consider sharing the cruise with another small science party if there is an additional proposal funded and the schedules accommodate it.

The general plan for each cruise is as follows:

1 port 12 hrs
2 VK826 29:09.5 88:01.2 490m 2 hrs 2

12 port
Summary of Facility Requirements: The preferred facility is the Atlantis with Jason or Alvin/Sentry. The ship must be able to accommodate an HOV or ROV, have dynamic positioning, a CTD winch and Niskin rosette, and preferably have a multibeam system. The submersible asset requires at least one 7-function manipulator, USBL and DVL navigation, a CTD, a 300 lb payload and 2 external hydraulic connections. We also prefer to have HD video and a high resolution still camera system.

Description of Repeating cruise requirements:
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
RV Atlantis is required if Alvin is used. If Jason is available, then any of the appropriate ships that are available for work in the Gulf of Mexico at that time would be acceptable. The minimum number of days to complete the required work would be 12. However, since there is only one cruise requested for this proposal, we have built in a 25% allowance for weather or mechanical issues. If the cruise is in the summer, the weather issues should be minimal, but in the Spring or Fall this is a conservative estimate.

or to list additional port stops
Gulfport MS results in the shortest transit to our starting and ending site. We have planned a round-trip cruise starting and ending at our eastern-most site, with a trip out to the western-most site (~400 nm away) in the middle. Alternate ports include Port Fourchon LA, or Galveston TX. If Galveston, a linear cruise plan could be developed.

Explanation of Science Party Requirements and Technician Requirements We would include a science party of 20 plus approximately 10 for the Alvin or Jason group (including SSSGs). If other submersible assets are provided, the number of operator provided technicians would be adjusted accordingly. The science party can also be smaller if there is insufficient bunk space on the vessel provided.

requirements that could affect choice
of ship in scheduling.

Dynamic positioning is required for ROV and HOV use. The fiber would normally be supplied by the ROV operator and is not necessary here if that is the case. Multibeam bathymetry is requested and would be used in case of down time due to weather or technical issues. The other equipment includes a standard CTD and Niskin rosette with hydrowire for water sampling.

Requirements and list description
and provider for "other" systems.
Use of Jason or Alvin is preferred. If Alvin is selected, we would strongly prefer to include the Sentry AUV with Alvin in order to maximize the use of the ship time. We have successfully used Sentry with Alvin in the Gulf of Mexico in Dec 2010 in order to survey surrounding unexplored areas at night during Alvin's surface interval. Other HOVs (if available) or ROVs would be acceptable if they meet the following criteria:
7-function manipulator (minimum of one, two preferred)
CTD
300 lbs payload
2 external hydraulic connections
USBL navigation
Doppler velocity log navigation (preferred but not required)
HD video preferred
high-quality still imagery
