Discussion on:

Dredging the past to create a better shipping future

In the late 1980s the Army Corps of Engineers' through its Vicksburg Waterways Experiment Station sponsored an economic demonstration project of the beneficial uses of dredge material containment areas. One project was located along the Brownsville, Tx. Navigation District ship channel. The project examined the economic potential of using the dredge material containment ponds (DMCP) for aquaculture during the 6 years those already constructed ponds lay idle during the avg. channel dredge cycle. We grew marine shrimp in two large DMCPs totaling about 240 acres. The project lasted three+ years and the results were published and presented in the Proceedings of the National Workshop on Containment Area Aquaculture in South Padre Island, Texas 11-15 November 1991. I managed the shrimp production project, helped produce two videos on the project, and contributed to a number of publications detailing the economic, legal and technical aspects of the project results. For more information you can contact the Waterways Experiment Station in Vicksburg, MS. and or Durwood M. Dugger, BCI, Inc. www.biocepts.com.

Dredging material from Norfolk VA harbor prior to the Civil War was used to top off fields played out by years of tobacco growing and backfill coastal swamps for use as additional fields.

I was there in 2008 and they were pumping dredging material onto one such coastal swamp to protect a new resort on Virginia Beach.

One such backfilled swamp field filled in during the 1860s was developed as housing in later decades. The area has settled over 14 inches since the houses were built, but that has not stopped the global warming nut jobs from blaming global warming for the floods that have increasingly hit the area. As this story portrays the problem.

The calmer people in the city like to blame global warming and recognize the sinking ground as a contributing factor.

The realists know it is just the sinking ground.

A similar situation is happening with Plum Island MA. The island mostly did not exist until the rock jetties were installed at the Merrimack River in the mid 1800s to stabilize the mouth of the river. Prior to the jetties being built the mouth of the river would move up to a mile some years based on how bad the winter storms eroded the coastal river plain.

Much of the original island was created by the dredging of the first fixed mouth of the river. When the island was nearly wiped off the face of the earth by a series of storm in the late 1890s into the early 20th century it was a manmade retaining wall and more dredging that rebuilt the island to slightly larger than its present size.

Dredging during WW II to open the Parker River channel to the sea for fishing trawlers briefly shrunk the island.

In recent decades storms have again been eating at the island, but in the past 10 years global warming is magically to blame. Not mother nature moving the river again or fools building on the shifting sand.

You should really loathe and hate yourself if you truely hate idiots aka John McGrew...

So is anyone who believes in global warming a "global warming nut job"? I would say that anyone who is too lame to see the painfully obvious is a nut job. The painfully obvious is that global warming is real and a direct result of man made pollution.

We (the global warming nut jobs) don't blame rivers moving and erroding on global warming. We blame rising sea levels and increasingly unstable weather (increased flooding, drought, hurricanes, and tornadoes) on global warming.

Dredging is fine and doing stupid things with the dredged material is fine too (like back filling a swamp and building houses on it).

We realize that precipitation and tidal movements of the oceans erode land. Only an self-loating idiot hater would think we blame any of that on global warming.

I'm curious John... Are you paid to troll here? Being a denier, why on earth would you come to Smart Planet?

I tried asking HI that back when we first met here a few years ago and go no answer. I think he's immune to the irony of his name.

But they do blame global warming in both these cases and many others.

Even in the face of proof that other reasons are behind the problems.

In my book that qualifies as a nut job.

It is also funny that some of you think I would bother with 2 accounts on this site.

Just because it may be a common practice among you and your friends, do not impose your guilt on others.

But thanks for the laugh.

Everyone here is entitled to their opinion. Whether you like it or not. Personal attacks for those opinions are not welcomed.

Now that we have all gotten our current personal pet itches out for one and all to enjoy, pick at and attempt to cure, here is a point that wasn't really touched upon. Unions, admittedly the recent strike by the Longshoremen on the West Coast was fairly short term as these things go, it does show one of the things that can drive these vessels to the East Coast to unload their cargo rather than take the short trip to the West Coast and drop it all off.

The company I work for here in Nevada had to wait nearly three weeks for a container load to be delivered to our warehouse that will make my job a right royal pain for the next couple of weeks as we have to pick up substitutes that were taken to locations, replace them with the correct products and then return the substitutes to stock. Having to pay for spinning our wheels doing this sort of thing is an expense that my company shouldn't have to deal with in a difficult economy. This sort of thing will make all those millions that the East Coast had invested in future projects have a reason for being but not at the expense of the small company.

With the expansion of the Panama Canal to handle larger ships there are many ports on the Gulf Coast and East Coast planning to handle the larger ships.

Those port workers might lose some jobs if a third of their cargo goes to other ports closer to the final destinations.

did ms. kaplan really write this piece? Or, like so many "newspapers" and "news shoows" was this a marketing piece of some kind, pre-written and released?

This took months.

In the food industry for instance, meat suppliers and butchers need to be able to freeze and store large quantities of meat.
