Summary of Field Work: |
This research project is a large-scale population survey incorporating multiple sampling methods to independently (separate from the SEDAR process) estimate the abundance of age-2+ red snapper (Lutjanus campechanus) in the northern (U.S.) Gulf of Mexico. Surveys are being conducted on the continental shelf across 3 habitat types (artificial reefs, natural hardbottom, and uncharacterized bottom), 3 depth zones (10-40 m, 40-100m, and 100-160m), and 5 regions (west FL, north FL, MS/AL, LA, and TX). A suite of methods are being performed to optimize results: habitat classification, direct visual counts, acoustic surveys and mark-recapture tagging studies. This abundance estimate will be used for comparison and integration into the NOAA red snapper stock assessment. |
|
Summary of Facility Requirements: |
For research cruises aboard the R/V Pelican, no biological sampling or processing will be required during this cruise as only visual and acoustic data will be collected. No diving will be required.
1) We will require only daytime operation. We will supply our own CTD, EK80 acoustic echosounder/towfish and VideoRay Mission Defender ROV.
2) We will need to stay in position while our ROV is deployed with a weighted tether.
3) We'll also need the ability to tow our acoustic towfish in a specific transect pattern, which is relatively small given the size of the Pelican.
4) Our EK80 must be run off the deck because we don't have enough cord to run it through the cabin.
5) A computer will need to be set up within a few feet of the acoustic towfish deployment.
6) There is potential that we may couple cruises with Jay Rooker's lab so they can collect visual data using their towed camera. If that is the case, then his requirements for operation will also need to be met (to be determined). |
|
Summary of other requirements and comments: |
1) We will need a sea state of 3-4 ft. or less to complete our video surveys successfully, as anything greater than that would not be amendable to ROV operation. Therefore, we would like to request a weather clause before scheduling a contract.
2) To minimize poor visibility during this cruise, we are requesting a preferred time frame between early June and August 2019, but May 2019 could potentially work for us as well. Our crew is available during the week of July 4th. |

Optimum Start Date:
|
6/1/2019 |
Dates to Avoid: |
1) Since this cruise will be ROV work, we'll need to select dates that optimize underwater visibility. Therefore, dates before June 1st, 2019 may be less likely to provide the conditions we need.
2) Our project end date is 8/31/19, therefore we won't be permitted to accept any cruise dates after that date. |

North TX shelf |
| Description of Op Area: |
This research cruise will hit predetermined random stratified sampling locations (to be selected) on the northern Texas shelf (list of coordinates available upon request, there are 30 total but we won't be able to hit all of them). Our field sites will include 5 locations in the Flower Garden Banks National Marine Sanctuary (east and west bank as well as Stetson). Direct-count surveys using remotely-operated vehicle (ROV), bioacoustics and a towed camera will take place at natural hard-bottom and artificial reef sites at depths up to 160 m. |

Explanation of Science Party Requirements and Technician Requirements |
For our acoustic echosounder transects, we ill need to tow a specific "flower pattern" with our towfish, with the ship running ~4 knots if possible. See additional requirements under "Summary of facility requirements" and "Summary of other requirements and comments." |

For ROV work, dynamic positioning would be preferred. However if this is not possible, then if the captains can manually hold station, that will work for us. |
