Trip Summary
During this period, there were 5 construction trips made to spot rubble deployments by Mississippi Power Company (MPCo) to the Round Island Reef and Horn Island Middle Ground (FH-10) Sites. MPCo contracted Vice Construction to perform the deployments. The amount of rubble deployed is estimated at 1500-2000 cubic yards.
In addition to the rubble deployment trips 2 trips were made on October 26 & 27 to assist the Gulf Coast Research Laboratory (GCRL) in releasing 1200 young red snapper into the FH-1 Site. Pictures and more details can be found at the RSCA web site at http://rsca.org

991022 FH-10 Rubble - Horn Island Middle Ground (ID=230F10)
This rubble was deposited within a 200 foot radius at the following coordinates. During this deployment, the Tug Boat made a maneuvering error that caused the barge to bump into the marker piling breaking it off. The light and mounting hardware was retrieved for re-deployment at a later date. The surrounding depth was 14.5 feet with a minimum depth of 9 feet recorded. DGPS Info: Tracking 11 Satellites, a hoop of 1.2, and a calculated position accuracy of within 10 feet. The predicted tide level was about 1.3 feet at the time of deployment. Predicted tide range for the day was 1.1 to 1.4 feet with High Tide occurring at 947 AM.
