How-to stop oil leak – from DeepWater Horizon Oil Spill visitor

May 29th, 2010 13 comments

Look over my design on how to crush the casing to stop the leak. See drawing attached. This will crush the casing to stop the flow of oil. The leak we are being showed is very small to the one at the end of the casing. They don’t wont us to see that one. It’s much larger. The C-Clamp smasher is very easy to build and install with ROV help. Please forward to who ever could help me get this in the Wright hand to see how important this matter really is. I work for a major wellhead company in Corpus Christi and this is the kind of problem’s I deal with. Coming up with the answer to fix major issues or customer are having with their well. This will work.

Please forward to anyone who could help get this going. Our water and beaches need to be saved. And soon


Gulf Oil Spill Starts to Worry New Jersey Beaches

The New Jersey Department of Environmental Protection said it is “improbable” that the BP oil spill will have any effect on the Jersey Shore, but it appears to be taking no chances.

“We are very optimistic the oil will not reach New Jersey and will not affect fishing nor the summer beach season,” said Commissioner Bob Martin in a statement.

Nevertheless, the state has mobilized the DEP, State Police, Emergency Management, Homeland Security and others to “put together a plan of action” if there is any impact.

For weeks now, scientists have worried that the Gulf’s Loop Current will pick up some of the oil slick and carry it though the Florida Strait and into the Gulf Stream that hugs the coast up to Cape Hatteras, and farther up the coast is still just 80 or 90 miles offshore from New Jersey and New York.

But even if that happens, “it would require a sequence of unlikely events” for the oil to actually come ashore, according to the DEP.

That could, however, include “water currents, depths, temperatures and salinity, plus weather conditions, including potential hurricanes and tropical storms,” said the DEP in its release.

The state is using the resources of both Rutgers University and the Stevens Institute of Technology to try to model the spill’s movement.

“We are running models every day. Trying to forecast what will happen,” according to Josh Kohut, assistant professor of Marine and Coastal Science for the New Jersey Agricultural Experiment Station at Rutgers.

If the worst were to occur, the DEP projects that the pollution would be in the form of “tar balls, hard-shelled, soft-centered objects.” At the earliest, it is projecting late summer for such an event, though again, the DEP calls that ‘unlikely.’

Glider status on the start of the memorial day weekend

May 29th, 2010 No comments

A crazy few days and the group has been busy.  What strikes me, is how this represents such a distributed group of diverse players. It harkens a new era of ocean research where distributed teams can work together and this represents a significant advance beyond the classical expeditionary mode of ocean research and exploration. Next week will offer a new suite of partners joining the fray.  As for the glider status today, we have 5 gliders in the Gulf. To the west we have two NAVO gliders (demarked by the two red triangles, thanks to Ken/Kevin and their NAVO teams!), and then iRobot Seaglider which is working in close conjunction with a ship doing spatial surveys.  Off the Florida coast USF launched the glider SAM and recovered BASS which had a leak.  Finally to the south we have the Rutgers IOOS glider.  Mote’s Waldo glider was recovered and should be redeployed in the next few days.

Starting with the NAVO Seagliders. They have been good progress over the Mississippi canyon.  The CDOM data shows enhanced values at depth with a almost a 10-fold increase with depth. Both gliders show this similar pattern.  Reflecting more the ignorance of this blogger, we need to establish what a reasonable baseline is for CDOM fluorescence in the Gulf so as to have confidence in ascertaining the anomalies when encountered.  If we use the Rutgers IOOS glider as a baseline the subsurface values are 25% higher however the highest values are much deeper then measured by the Rutgers system.

There was exciting information announced by Vernon that they believe the Seaglider has measured some CDOM anomalies that are likely associated with the oil.  The ship was nearby last night and hopefully discrete data will confirm the presence of the oil.  Given the efforts of being at sea we salute Vernon for keeping us in touch.  The Seaglider data is interesting and some of the environmental signals have definitely evolved over the last days. Temperature shows a strongly stratified systems with a major thermocline in the upper 50 meters water depth.  Salinity during the early days of the transect showed low salinity surface plumes associated with freshwater inputs.  The CDOM signals were high here and likely reflected enhanced concentration of riverine input as the CDOM declined dramatically when the salinity increased. Chlorophyll values were high throughout the surface waters in the areas where the salinity values were low, but since then the chlorophyll is found at depth and appears to be associated with the base of the thermocline. The CDOM signals in the recent days is very interesting, we see enahnced values associated with the high chlorophyll, my speculation is that this material is produced by the phytoplankton.  Oxygen values also peak with the enhanced chlorophyll. However their are enhanced values found below the chlorophyll maximum with a recent tongue associated with 200-400 meter depths.  The CDOM values are not associated with phytoplankton and are associated with the lowest oxygen values. There also recently is enhanced values found deep at around 1000m which is very distinct and bright.  We are anxious to some confirmation data from Vernon and ship efforts!

The two gliders to the south are making good progress. Both SAM and Ru21 are feeling the large eddy.  With strong(!) southernly currents.  The glider currents are confirmed by the HyCOM modeled currents.  We expect RU 21 to make small progress eastward as it is sling shoted around on the eddy.  The Horizon Marine drifter (green icon to the east) in the eye shows the slower currents internally in the eye of the eddy.

SAM shows a stratified system, with the thermocline found around 30-35 meter water depth.  Particle concentrations, as indicated by the the optical backscatter, is enhanced at the thermocline, similar the Seaglider to the north.  CDOM values show enhanced values at depth in good agreement with the RU21 glider to the south.

RU21 has passed through the interesting low salinity filament that stimulated much discussion over the last two days. The filament showed enhanced CDOM to the surface associated with the low salinity water.  Particle loads where not high in the filament. Generally particle concentrations have dropped as we have moved off the continental shelf.  Offshore waters west of the filament show a deepening thermocline ~80 meter with low particle and CDOM concentrations.


Big news from Vernon and iRobot team

The iRobot Seaglider has produced what I think is the very first glider profile ever that shows the deep CDOM signal.  You can see these data and those that follow at:

This is very exciting; this glider will help immensely to track and map this plume.   We are currently just a few miles from this location and are seeing the same signal and we’re also collecting samples to ascertain what is producing this signal.

Please let me know if you have any questions about this or contact Rosario with iRobot at
