Time-lapse of Processing Mud Samples

Time-lapse of the whole process. The entire process took about 20 minutes.

Sharing Finds

Coring Rig

With the sun rising over the horizon, the coring rig sits ready for deployment.

Deployed Coring Rig

The piston coring rig deployed over the stern, and just prior to sampling.

Preparing Wood Fragment Samples

Sediment from the core catcher contained wood fragments, which were rinsed and catalogued.

Shell Deposit

A shell deposit was observed in the core when sectioned into smaller pieces.

Map of Incised Trinity/San Jacinto/Sabine Channel

Geological mapping shows the broad extents of the former, incised, Sabine and Trinity/San Jacinto River Valleys (after Simms et al., 2008).

Split Cores

A split core, recovered in 2010, shows the transition from modern marine sediment (top right), through the Pleistocene clay (lower left).

Shipwreck

A shipwreck in 80 feet of water in the northwestern Gulf of Mexico was imaged using side-scan sonar (left); photographs taken by divers of the same wreck were obscured by lack of light and sediment in the water column (right).

Velocity Cast

A velocity cast shows the actual speed of sound throughout the entire water column, as changes in salinity, temperature, and density alternately increase and decrease velocity.

Sub-bottom Profile
