Door Point: A Buried Volcano In Southeast Louisiana – A Paper Written in 1976

An exploratory well, the Shell Oil Company, State Lease 3956 No. 1, Offshore St. Bernard Parish, Louisiana, was completed in 1963 at a total depth of 8538 feet. The last 1300 feet of hole was cored and drilled through volcanic material of Late Cretaceous Age. The location of this well is shown on Figure 1.
Pre-drilling seismic data had revealed the presence on this prospect of intrusive material with a density slightly higher than that of the surrounding sediments. Gravity data defined a weak maximum here, and no salt was believed to be present.
The igneous material consisted of angular fragments of altered porphyritic basic rock. In cores it proved to be evenly bedded and cemented by sparry calcite. Radioactivity age dating fixed a minimum age of crystallization of this rock at 82 m.y. + 8, or middle Late Cretaceous (Austin). Bulk density of the igneous rock ranged from 2.02 gm/cc near the top of its occurrence to 2.53 gm/cc near the bottom of the well.

Three gas accumulations, with an aggregate thickness of 38 feet, were encountered in the Miocene section between 5092 and 6219 feet in the Shell well. Gas-bearing sands were not present in two other wells drilled later on the same structure (Fig. 2).


Although evidence of Late Cretaceous volcanic activity is widespread in northern Louisiana, as well as in Mississippi, and southeast of Louisiana in the Gulf of Mexico, the Door Point prospect lies within an area that had been previously designated as being free of volcanism.

Massive fish kill in Myrtle Beach in South Carolina and Galveston Bay in Texas


Wonder how much BP paid in advertising dollars to keep the media silent and the people brainwashed into forgetting the disaster that hit those shores little more than two years ago.

On August 17, 2012, all along the Myrtle Beach coast, beach-goers were finding mixed species of dead fish floating in the surf or washing up on shore – sting rays, pompanos, whitings, flounders… The fish did not have any obvious signs of trauma.

Phil Maier, director of Coastal Reserves and Outreach for DNR office in Charleston, said there were groups of dead fish found between 28th and 68th Avenues North Friday. He said that water conditions are right for Friday’s fish kill to be caused by hypoxia, or low dissolved oxygen in the ocean. There have been light southwest winds, warm water and spring tides. Maier said it is very likely it was the dissolved oxygen levels that killed the fish, but DNR, the Department of Health and Environmental Controls and scientist at Coastal Carolina University continue to take samples and investigate the cause. Another possible reason is the red tide.

The occurrence of red tides in some locations appear to be entirely natural (algal blooms are a seasonal occurrence resulting from coastal upwelling, a natural result of the movement of certain ocean currents) while in others they appear to be a result of increased nutrient loading from human activities. Other factors such as iron-rich dust influx from large desert areas such as the Saharan desert are thought to play a major role in causing red tides.

Red tide is also potentially harmful to human health. Humans can become seriously ill from eating oysters and other shellfish contaminated with red tide toxin. Red tide algal bloom can potentially cause eye and respiratory irritation (coughing, sneezing, tearing, and itching) to beachgoers, boaters and coastal residents. People with severe or persistent respiratory conditions (such as chronic lung disease or asthma) may experience stronger adverse reactions.

Red tide killed more than million fish in Galveston Bay, Texas

Wildlife officials estimate more than a million fish have been killed in Southeast Texas by the algae bloom known as red tide. The Texas Parks and Wildlife Department offered the estimate after a flyover on August 16 in the Galveston area.Tens of thousands of dead fish began washing up on beaches last weekend. Water samples collected Monday confirmed the red tide at various sites in Galveston Bay. Parts of Galveston Bay have been closed to shellfish harvesting because of the algae bloom, which can cause respiratory problems.

The human health effects associated with eating brevetoxin-tainted shellfish are well documented. However, scientists know little about how other types of environmental exposures to brevetoxin—such as breathing the air near red tides or swimming in red tides—may affect humans.

In large concentrations, the algal bloom becomes visible as a brown or red discoloration floating on the surface waters. No visible blooms have been reported though biologists did observe one area of discolored water in Keller Bay near the Alcoa plant and around Aransas Bay.

Red tides in the Gulf of Mexico are mainly a result of high concentrations of Karenia brevis, a microscopic marine algae that occurs naturally but normally in lower concentrations. In high concentrations, its toxin paralyzes the central nervous system of fish so they cannot breathe. Dense concentrations appear as discolored water, often reddish in color. It is a natural phenomenon, but the exact cause or combination of factors that result in a red tide outbreak are unknown.

15 dead sharks wash ashore in Manatee County

If you run into a dead shark on the beach, MOTE asks that you contact them at (941) 388-4441.

MANATEE COUNTY —

A mystery is brewing on Manatee County’s beautiful beaches — researchers are trying to figure out why sharks are washing ashore dead.

Recently more than a dozen dead sharks were found on the north ends of Longboat Key and Anna Maria Island.

“There were no real indicators of what went wrong with them,” Dr. Nick Whitney, Staff Scientist for the Center for Shark Research at MOTE Marine Laboratory said. “There are no obvious signs of damage from fishing or net damage or anything like that.”

The species of sharks found were bonnetheads, blacknose and sharpnose.

Whitney said he’s ruled out the possibility that the sharks died as a result of last year’s oil spill.

“Oil spill is pretty unlikely because these animals tend to be coastal,” said Whitney. “They move up and down coast, but they wouldn’t tend to go off shore and in deep water where oil is.”

For now, Whitney says what happened to these sharks remains a mystery.

Researchers have sent samples from the sharks to a different lab to try and see if red tide killed them.

However, they say this is highly unlikely since they have not detected any red tide in the area.

MOTE researchers say finding a dead shark now and then is not rare, but it is uncommon to find a group of them dead within a few days.
