Salt Dome Formation

This video is an animation of how a salt dome forms, using East Flower Garden Bank as an example.

The video begins by showing layers of sediment on the sea floor. The white layer (third up from the bottom) represents salt deposits caused by evaporation of shallow seas thousands of years ago.

Over time these salt deposits, which are less dense than the layers above them, begin to push upward. This causes the overlying layers to buckle and bulge upward as well. As the dome begins to take shape, other structures appear on top. These represent the beginnings of coral reefs.

Pressures from sediment layers and the ocean above have also resulted in the formation of oil deposits beneath the sea floor. These deposits tend to seep between layers and are often found trapped above and around layers of salt. This is represented by a thick black line forming above the salt layer in the animation.

Evenutally cracks and fissures form in the layers above and below the salt as a result of all the movement. These cracks (vertical black lines) allow some of the liquified salt to seep up to the sea floor forming brine (salt) seeps.

At East Flower Garden Bank, this has resulted in the formation of a large depression that traps the very dense water caused by the brine seep. The resulting "lake" is about 10 inches deep and contains hypersaline (super salty) water at about 200 parts per thousand (ppt). Normal seawater is about 35 ppt. The animation flies up and over the dome and rotates around to show this depression and the channel that eventually allows the brine to mix with regular sea water.

The video then zooms back to the top of the dome and shows the growth of coral reefs in patches on its surface. It then zooms out from the reef, shows the brine seep again, and continues pulling back until a large, three dimentional cube is visible. This cube shows the sloped sea floor, the sea surface about two thirds of the way up, and air above that.

The video ends with a measurement bar showing the depth of each layer in the cube:

  • Water Surface 0m
  • Coral Growth -20m (60 ft)
  • Brine Seep -68m (215 ft)
  • Base of Slope -80m (240 ft)

Dolphins at Stetson Bank

During a research trip in May 2013, researchers were treated to a visit from a large pod of Atlantic Spotted Dolphins at Stetson Bank. R/V MANTA deckhand Julia O'Hern was able to capture this video footage while snorkeling.

2013 Long-Term Monitoring Cruise

Every year, sanctuary researchers collect long-term monitoring data on the reefs of Flower Garden Banks National Marine Sanctuary. This includes running photo transects, taking repetitive photo station images, and fish surveys, among other activities. And, of course, random observations of what is happening during these dives.

0:00-0:05 Title page - NOAA's Flower Garden Banks National Marine Sanctuary, East and West FGB Long Term Monitoring, 2013

0:05-0:11 A Chub (Kyphosus sp.) swimming up to the camera.

0:11-0:21 A scuba diver with a long t-frame camera setup taking a photo at a repetitive photo station on the reef.

0:21-0:31 A scuba diver laying a random transect line by unreeling a measuring tap across the reef in a specified direction.

0:31-0:38 Moving along a transect line as it lays across the reef.

0:38-0:47 A scuba diver with a short t-frame camera setup taking photos at a specific point along a reef transect, then picking up to move further down the line.

0:47-0:54 A scuba diver swimming in the midst of a school of Bar Jacks (Caranx ruber) over the reef.

0:54-1:03 A large invasive Lionfish (Pterois volitans) hovering just above the reef.

1:03-1:18 A scuba diver using a Hawaiian sling spear to capture a large invasive Lionfish (Pterois volitans) then stuff it into a PVC tube called a Zookeeper for safe keeping.

1:18-1:42 Side and overhead views of a Manta Ray (Manta birostris) swimming up in the water column with two remoras attached on top of it's head. Flecks of plankton in the water catch the light and for a brief moment, the dive ladder of R/V MANTA is visible above the manta ray.

1:42-1:59 Belly view of a Manta Ray (Manta birostris) swimming over and past the camera in open water with the sun reflecting off the waves at the surface.

1:59-2:10 Several Great Barracuda (Sphyraena barracuda) and a Horse-eye Jack (Caranx latus) in blue water with a large school of Chub (Kyphosus sp.) and Bar Jacks (Caranx ruber) in the background.

2:10-2:45 A group of three Mobula Rays (, each with at least one remora attached, gliding above the reef in formation. Camera pans behind this group and picks up a fourth Mobula Ray with remoras. Video continues to follow the group of four as the slowly swim away across the reef.

2:45-3:06 Belly view of a single Mobula Ray (Mobula sp.) with attached remoras. The ray slowly glides, then turns and shudders, sending ripples through its fins.

3:06-3:18 Following from slightly above and behind the same Mobula Ray (Mobula sp.) as it swims past a school of Great Barracuda (Sphyraena barracuda)and away from the camera.

3:18-3:48 Belly view of a Mobula Ray (Mobula sp.) swimming near the surface of the water where ladder lines are trailing behind R/V MANTA. The camera gets closer until it is following directly behind the Mobula Ray as it swims away.

Secret Reef Exhibit at Tennessee Aquarium

Secret Reef is a 618,000-gallon exhibit at the Tennessee Aquarium in Chattanooga, TN, that represents Flower Garden Banks National Marine Sanctuary. Aquarium staff worked closely with sanctuary staff during the development stages to ensure an accurate representation.

This video takes a look through just one of 33 viewing panels into the exhibit. A variety of tropical fishes, southern stingrays, and sandbar sharks swim by the window as the video progresses.

Stetson Bank Monitoring Sequence

Long-term monitoring has taken place at Stetson Bank since 1993. As part of this monitoring, photos are taken at specific locations on the reef, year after year. then compared to identify changes in species composition on the reef. Every attempt is made to get the same size reef section with the same camera orientation each year, but you will notice slight variations.

This video sequence shows a series of photos taken at Pin 28 at Stetson Bank from 1993 to 2008.

For more information about the challenges of long-term reef monitoring, please visit our Monitoring page.

An educational activity using photo sequences is also available. You can download the Reef Monitoring lesson from our For Teachers page.
