Web Science Made Silly: “Scientists Warn Gulf Of Mexico ‘Supervolcano’ About To Erupt”

Visitor geological storytelling by David Middleton

In my latest publish, How Local weather Change Buried a Desert 20,000 Ft Beneath the Gulf of Mexico Seafloor, we mentioned the rifting that enabled the opening of the Gulf of Mexico. In one of many feedback, TTY introduced up a latest paper on long-extinct volcanic exercise within the Japanese Gulf of Mexico, which jogged my memory of the “volcano” that was drilled again within the 1960’s close to New Orleans. After I Googled Gulf of Mexico volcanic rocks, I discovered extra science fiction than science.

I’ll begin with the science…

Cretaceous volcanoes within the Gulf of Mexico

Door Level is in Louisiana State waters, simply offshore St. Bernard Parish, in an space that was regarded as freed from Mesozoic volcanic exercise.

Determine 1. Door Level location map. (Braunstein & McMichael, 1976)

The Door Level “volcano” was found by Shell after they drilled into it in 1963.

Determine 2. Cross Part of Door Level Construction.
(Braunstein & McMichael, 1976)

The Door Level construction technically isn’t a volcano.

An exploratory properly, the Shell Oil Firm, State Lease 3956 No. 1, Offshore St. Bernard Parish, Louisiana, was accomplished in 1963 at a complete depth of 8538 toes. The final 1300 toes of gap was cored and drilled by means of volcanic materials of Late Cretaceous Age. The placement of this properly is proven on Determine 1.

Pre-drilling seismic knowledge had revealed the presence on this prospect of intrusive materials with a density barely increased than that of the encompassing sediments. Gravity knowledge outlined a weak most right here, and no salt was believed to be current.

The igneous materials consisted of angular fragments of altered porphyritic fundamental rock. In cores it proved to be evenly bedded and cemented by sparry calcite. Radioactivity age relationship fastened a minimal age of crystallization of this rock at 82 m.y.+eight, or center Late Cretaceous (Austin). Bulk density of the igneous rock ranged from 2.02 gm/cc close to the highest of its prevalence to 2.53 gm/cc close to the underside of the properly.
Three gasoline accumulations, with an mixture thickness of 38 toes, had been encountered within the Miocene part between 5092 and 6219 toes within the Shell properly. Gasoline-bearing sands weren’t current in two different wells drilled in a while the identical construction (Fig. 2).

Though proof of Late Cretaceous volcanic exercise is widespread in northern Louisiana, in addition to in Mississippi, and southeast of Louisiana within the Gulf of Mexico, the Door Level prospect lies inside an space that had been beforehand designated as being freed from volcanism.

Braunstein & McMichael, 1976

Though it’s clearly composed of reworked volcanic materials.

The Door Level construction penetrated by the Shell Oil S.L. 3956 properly no. 1, situated offshore in St. Bernard Parish Louisiana represents the singular noticed subsurface prevalence of igneous rock in your complete offshore area of the GoM that’s Cretaceous in age. Recognized within the literature as a volcano, sill or different major intrusive/extrusive characteristic, with an age of 82 ± eight Mya, the Door Level “Volcano,” has acquired little or no examine since its discovery within the 1970’s.

Preliminary examine of the core reveals that the unit consists of volcaniclastic rocks. Preliminary overview of the geophysical logs supplied by Shell Oil and Drilling Information present a drastic and obvious offset within the resistivity, with a maligned or absent deflection of the Spontaneous Potential curve. The sequence of volcanics lengthen vertically a minimal of 396m with no base recognized, and the singular cored interval taken of the ultimate eight.5m. Preliminary petrographic examination has revealed there to be each large un-bedded polymictic agglomerates in addition to bedded volcanic ash. The basalt cobble agglomerates sequentially alternate with the packages of finer grained volcanic ash. Grain measurement for the igneous cobbles inside the agglomerates vary in diametric extremes from a most of 5 cm to a minimal of 1 – 2 cm. Sedimentary constructions are absent within the coarser sequences, however are exhibited within the volcanic ash beds, within the type of cross bedding. The clast populations range in composition from fragments of sedimentary rock, to the igneous rocks of curiosity. Possessing a porphyritic texture and angular in look the clasts comprise seen clinopyroxene phenocrysts, in an aphanitic groundmass; CI > 90.

These outcomes counsel the cobbles are sourced from a number of volcanic facilities, and have undergone a multistage cooling historical past. Coupled with the presence of the calcite cement, the cross bedding is indicative of a marine or fluvial depositional system. We’re in a position to reconstruct a regional story of episodic volcanism within the nascent Gulf of Mexico Rift throughout the late Cretaceous.

Door Level is almost certainly a salt or shale diapir (piercement construction) that carried volcanic materials up with it.

It’s not the one volcanic oddity within the Northern Gulf of Mexico.

Determine Three. Location maps for Door Level (left) and Alderdice Financial institution (proper, Rezak & Tieh, 1984). Click on for picture.

Alderdice Financial institution is a salt diapir, which seems to have transported a number of giant blocks of basalt to the seafloor.

A basalt outcrop was found on Alderdice Financial institution on the outer Louisiana continental shelf. The basalt reveals an age of 76.eight ± Three.Three × 106 years. Textural, mineralogical, and chemical traits point out that it’s an alkali basalt of shallow intrusive origin. It was in all probability dropped at the seafloor by salt tectonics and uncovered resulting from salt dissolution.

Backside Depth Vary: 165-240 toes (50-73 meters)

Alderice Financial institution is situated about 52.5 km (32.5 mi) southeast of Sonnier Banks, about 60 km (37 mi) west northwest of McGrail Financial institution, and 157 km (97 mi) east northeast of East Flower Backyard Financial institution. The financial institution is an oval mendacity in an east-west route, and covers an space of about 16 km2 (10 mi2).

Three spectacular basalt spires of Late Cretaceous origin (~77 million years outdated) are discovered at Alderdice Financial institution. These are the oldest recognized uncovered rocks on the continental shelf off of Texas and Louisiana, and distinctive geologic options for this area. The outcroppings crest at about 50 m (165 ft), with their bases at about 73 m (240 ft).

Analyses of latest gravity, magnetic and excessive decision seismic surveys have pretty clearly revealed the traditional rift system within the Japanese Gulf of Mexico (Lin et al., 2019).

An extinct, late Jurassic-to-earliest Cretaceous ridge-and-fracture zone geometry within the western Gulf of Mexico (GOM), and extinct seafloor ridge segments within the japanese Gulf of Mexico (EGOM), had been beforehand recognized utilizing the vertical gradient of satellite-derived free-air gravity knowledge. Round gravity anomaly lows, and magnetic anomaly highs, over the middle of spreading ridge segments are interpreted as giant volcanic facilities that erupted inside a late Jurassic-to-earliest Cretaceous,
slow-spreading heart. Detailed mapping of oceanic basement utilizing oil trade seismic knowledge signifies that the EGOM oceanic ridge system is characterised by 30-60-km-long spreading ridge segments, that embody 15-km-wide, 2-km-high axial volcanoes of their facilities, and nodal basins at their ends. Stratigraphic proof from seismic reflection knowledge tied to a
deepwater properly signifies that volcanism alongside the spreading ridge ended across the identical time (Berriasian), or barely after (Valanginian), the cessation of seafloor spreading within the EGOM. Flowlines of late Jurassic-to-earliest Cretaceous seafloor, based mostly on a pole of rotation from the geometry of GOM spreading ridges and fracture zones, present a great match with gravity and magnetic anomalies alongside the Florida and Yucatan conjugate margins of the EGOM. Mapping of age-dated, stratigraphic downlaps onto the oceanic crust is in line with an interpreted ridge soar firstly of seafloor spreading (Kimmeridgian) to the southwest, and in the identical southwestward route of a beforehand inferred mantle plume within the central
GOM. Our Three-D gravity structural inversion of the Moho requires 6.four km thick oceanic crust within the northwestern EGOM, and 5.5 km thick oceanic crust in southeastern EGOM. We interpret this along-ridge, thickness variation to mirror sooner spreading and thicker oceanic crust farther from the opening pole situated within the southeastern GOM.

Lin et al., 2019

The EGOM volcanics pre-date Door Level and Alderdice Financial institution by about 50 million years

It’s quite stunning that these volcanic oddities haven’t acquired extra analysis consideration… Possibly if there was oil in basalt, they’d have… 😉 Nevertheless, they’ve acquired some latest consideration from some “alternate media retailers.”

One thing Extremely Unusual Is Going On In The Gulf Of Mexico As Temperatures Hit 130+ Levels Repeatedly In One Location – Is Lengthy Dormant Volcano Awakening Or Simply A Weird Anomaly?

Again on January 11th, we reported on ANP that a number of days earlier than an enormous, 7.6 earthquake struck within the Caribbean Sea, inflicting a tsunami warning to be issued to a number of Caribbean islands, ocean water had instantly and mysteriously ‘disappeared’ in areas greater than 2,000 miles aside, each north and south of the epicenter of that quake.

As videographer MrMBB333 advised us in a video that we used inside that story, “water is attempting to inform us one thing”.

Properly if water instantly and mysteriously disappearing within the Gulf of Mexico and the Pacific Ocean then was attempting to inform us one thing, then actually temperature spikes of over 130 levels within the Gulf of Mexico should be attempting to inform us one thing, too!

As we see from MrMBB333 within the 1st video beneath, one thing extremely unusual is occurring within the Gulf of Mexico with air temperatures recorded at over 130 levels over and over the previous week, with temperatures fluctuating between ‘regular’ temperatures within the 75 to 80 levels vary earlier than instantly taking pictures as much as at the very least 133 levels as we see in movies and the 2nd picture beneath.

[…]

Again on March 19th of 2013, Nesara Information revealed a narrative titled “A Buried Historical Volcano In Southeast Louisiana” wherein they advised us about proof of Late Cretaceous period volcanic exercise being widespread in Louisiana in addition to in Mississippi and southeast of Louisiana within the Gulf of Mexico.

Known as ‘Door Level’, the proof of volcanic exercise was discovered inside an space which had beforehand been designated as being freed from volcanism as seen within the subsequent picture beneath. Curiously, that ’igneous free’ space contains the place we at the moment are witnessing these excessive temperature spikes within the Gulf of Mexico as seen within the photos above and the movies beneath.
Would possibly an historical and long-dormant volcano be beneath the water of the Gulf of Mexico, instantly coming again to life, its venting inflicting these temperature spikes we’re witnessing? Far more on that principle beneath with proof that certainly we may be about to witness one thing un-thought of ought to a long-dormant volcano within the Gulf of Mexico be awakening.

The article options this picture… Does it look acquainted?

When you click on Learn the Complete Article, it takes you straight into The Twilight Zone…

Whereas the ‘Ring of Fireplace’ has been heating up with volcanoes throughout the planet now erupting and large earthquakes indicating a good larger one is unquestionably forward as we hear within the third video beneath from Infowars, it’s not misplaced on these paying consideration that the Gulf of Mexico borders the ‘Ring of Fireplace’ as we see within the subsequent picture beneath.

The largest Gulf on this planet, is it only a coincidence that the Gulf of Mexico is formed virtually just like the mouth of a huge volcano, with one facet ‘blown out’ that simply occurs to align with the Caribbean islands? We discover the speculation of the origins of the Caribbean to be very fascinating, particularly understanding that the Caribbean is a ‘giant igneous province’, volcano created. 

Whereas we are able to’t see any underwater volcanoes within the Gulf of Mexico, what if your complete Gulf of Mexico was the ‘mouth’ of the traditional volcano and the ‘supply’ of the Caribbean islands after they had been created between 69 million and 139 million years in the past? Whereas Wikipedia says the islands are regarded as linked to the Galapogos Hotspot, which is sort of distant, is the reality nearer to dwelling? 

Whereas we’re unable to see them, underwater volcanoes are nothing new and as the LA Instances reported again in 2014, scientists had just lately created a high-resolution map of the ocean ground revealing hundreds of underwater mountains and extinct underwater volcanoes that had by no means been recognized earlier than then. And whereas their map was twice as correct as any map of the ocean ground earlier than it, they shortly admit that it may solely resolve options at the very least a mile excessive or larger.

Enter this Could of 2017 story from Nationwide Geographic which makes use of a brand new ocean ground map created by a authorities company most have by no means heard of referred to as the “Bureau of Ocean Vitality Administration” but as we see within the this new imaging supplies beneath, we nonetheless know little or no concerning the ground of the Gulf of Mexico with the picture on the correct the best high quality decision that we now have, in contrast with the picture on the left exhibiting what we’d recognized earlier than.

The key authorities company’s map is outwardly imagined to be proof of a volcano.

Anybody acknowledge this? The excessive decision bathymetry mapping was lined right here: U. S. BOEM Releases Highest-Decision Bathymetry Map of the Gulf of Mexico… Evah! Watts Up With That? Could 30, 2017. The precise picture is from an Eos article and it’s the seafloor expression of a salt dome rimmed by a salt withdrawal basin.

Determine 7. “Horseshoe Basin within the western Gulf of Mexico, as in contrast utilizing (left) the historic NOAA bathymetry map and (proper) BOEM’s new map. The basin incorporates a salt dome at its heart and is flanked by salt sheets. Motion of the salt is clear from the community of faults and rifts expressed on the seafloor across the basin, in addition to from the sediment particles flows seen falling down the slopes of the basin and onto its ground. Credit score: BOEM” (Eos)

The excessive decision bathymetry map was derived from 3d seismic surveys, which comparatively clearly picture the salt domes, sills, massifs and different halokinetic options that kind many of the hydrocarbon traps within the Gulf of Mexico and the rugose geomorphology of the seafloor on the continental slope. Calling this proof of a volcano is the equal of crater hunters circling up roundish options on satellite tv for pc photos and declaring them to be affect options… with out ever trying on the geology.

Scientists Warn Gulf Of Mexico ‘Supervolcano’ About To Erupt
March 15, 2018 Sean Adl-Tabatabai

Scientists have warned that extraordinarily excessive temperature readings emanating from the Gulf of Mexico within the final week may be a precursor to a deep underwater supervolcano eruption.
Scientists engaged on the RFS Viktor Leonov CCB175 recorded water off the South American nation of Ecuador disappearing on January 5. Three days later, on January eight, waters started disappearing off the North American Florida shoreline – which was adopted 24 hours later by an enormous 7.6 magnitude earthquake within the Caribbean Sea adjoining to the Gulf of Mexico.

With the common sea floor temperature of the Gulf of Mexico by no means falling beneath 23 levels Celsius (73 levels Fahrenheit) over the winter for the primary time on document final 12 months, and whose “Useless Zone” has grown to its largest measurement in recorded historical past, scientists aboard the analysis vessel say that no proof suggests these occasions are resulting from local weather change.

In contrast to their Western counterparts, these Russian scientists, when confronted by such mysteries, look backward in time to our Earth’s most historical tales and myths to see if parallels may be drawn to what’s taking place now—and that led an examination of the Maya peoples who in historical instances inhabited this whole area—even stretching into the American States of Florida and Georgia.

As documented by Carleton Faculty researcher Lyndon DeSalvo in his 2008 analysis paper titled “Bleeding Earth: Volcanoes because the Prototypical Mountains in Mayan Cosmological Previous”, the Mayapeoples tales and legends of their previous communicate of your complete Gulf of Mexico as being the place the place mountains come from—and, additionally disappear into—and whose solely modern-times clarification of is somebody describing the actions of a volcanic caldera—that may be a giant cauldron-like despair that types following the evacuation of a magma chamber/reservoir in a supervolcano eruption.

Disregarding the Maya peoples historical legends, tales and myths that the Gulf of Mexico may, certainly, be an enormous volcanic caldera, Western scientists have lengthy sought to find as to how got here to it got here to be formed like one—with the most recent try being made in 2002 when American geologist Michael Stanton revealed a speculative essay suggesting an affect origin (comet/asteroid) for the Gulf of Mexico—however that every one international geologists shortly rejected for its not having any credibility.

Coming nearer to the Maya peoples historical tales, nonetheless, was famous American geologist Dr. David Prior—who, whereas doing analysis at Louisiana State College (LSU), grew to become the primary scientist to doc volcanic eruptions had been, certainly, occurring within the Gulf of Mexico—and the invention of which he wrote about in his 1989 scientific analysis paper titled “Proof for Sediment Eruption on Deep Sea Flooring, Gulf of Mexico”.

Constructing on Dr. Prior’s scientific proof of volcanic eruptions occurring within the Gulf of Mexico, in 2003, “asphalt volcanos”—which had been by no means heard of earlier than—had been discovered forming in these waters, too—and that led to large effort, throughout the globe, to re-map all of the world’s oceans to discovery simply what number of underwater volcanoes there are—and when accomplished, in 2014, revealed hundreds of underwater mountains and extinct volcanoes that had been beforehand unknown.

This previous Could (2017), the primary in historical past detailed seafloor map of the Gulf of Mexico was lastly launched by the People—and whose beautiful findings revealed its deepwater seafloor was dominated by canyons, ridges, and faults—a few of whose fault strains unfold to the traditional Jackson, Mississippi, volcano—and with many believing that additional discoveries will quickly hyperlink your complete Southeastern United States to the scary Trans-Mexican Volcanic Belt.

At this level, my mind started to leak out of my left ear. If anybody wants me to clarify why nothing within the passage above is proof of volcanic exercise within the Gulf of Mexico, I might be blissful to take action within the feedback part… Trace: sediment expulsion, mud volcanoes and asphalt volcanoes aren’t associated to volcanism, magma or every other igneous course of… at the very least not within the Gulf of Mexico.

From abiotic oil, to The Weekly World Information, to Earth crustal displacement, to supervolcanoes within the Gulf of Mexico… Why is it that they virtually at all times cite “Russian scientists”?

In contrast to their Western counterparts, these Russian scientists, when confronted by such mysteries…

Within the case of The Weekly World Information, it was often, “based on Russian scientists, as reported by Swedish scientists (Fill within the clean: an oil rig drilled into Hell, a WWII bomber was situated in a crater on the Moon, Batboy is advising Invoice Clinton on the 1996 election).

Why did I take the time to debunk this nonsense?

As a result of it was each 1) enjoyable and a couple of) straightforward… Other than the minor mind hemorrhage.

There additionally appears to be a bent amongst some AGW skeptics to gravitate towards various “science” in areas apart from local weather. This needs to be achieved with care. And typically, even when achieved with care, it might probably result in malicious assaults by the Warmunists. Rejecting the so-called scientific consensus on AGW doesn’t logically require skeptics to reject all scientific consensuses. Whereas science isn’t a consensus constructing course of, most scientific consensuses are the results of hypotheses being examined and confirmed, resulting in scientific theories which show predictive talent… The idea of the formation of the Gulf of Mexico predicted that proof of Late Jurassic to Early Cretaceous rifting and volcanic exercise could be discovered the place it was subsequently discovered.
