Isn’t the replacement of sea water with fresh water a possible indicator of tectonic plate movement. Why are these idiots in India flcking to a beach with this indicator, and drinking dirty polluted water? Did India not learn from the tsunami that wiped out all hose people last time?
What’s your theory on tectonic plates? Why would this change saltwater to freshwater?
As for learning from the tsunami, you might find that the poorer people are, the more likely they are to be duped by so called “miracles”. I’m not sure if there’s research on this but I would hazard a guess that this would never happen in Los Angeles. Religion has its purpose and one of them is to give hope to the poor. I just hope nobody got sick.
Doesn’t fresh water replacing salt water sometimes indicate fresh water being pushed up by tectonic plates moving? The same thing that can initiate a tsunami. The government was supposed to have taught people the signs to look for that can indicate a tsunami may be coming. The campaign to educate the population doesn’t seem to have taken hold. The government doesn’t even list this as a possible reason, which is a problem, if this is a possibility. Please note that the article has this as a last line.
Last year, Mumbai residents flocked to a local beach after reports diamonds were washing ashore. Police said it was fragments of glass.
How many beaches have ever been the site of diamonds washing on shore to be gathered by the beachcombers. Shoes from cargo containers has happened, diamonds no.
Can this be a sign to leave the beach? I’m looking for verification, that I’m not dreaming this one up.
I don’t know where your getting religion inserted into my question, I didn’t mention it until the previous line in response to you. The people going there are a mix of different people for different reasons. I’m not going to side track the question into where your trying to take it.
I’d say he probably got the idea from this quote in the article you cited.
bolding mine
“Many saw it as a blessing from Makhdoom Ali Mahimi, a 13th Century Sufi saint.”
I’m not gonna get into a religious argument either but you gotta admit, the article put it out there first.
Here’s a better article:
It attributes the “sweet” water to an influx of fresh water from a local creek and a lake overflowing.
Pushed up from where? There’s no fresh water under the salt water of the ocean.
How is the appearance of freshwater an indication of an upcoming tsunami? What is the physics behind it? Water does push up (or down) during a tsunami but it is ocean water not freshwater. Were people is this area actually told that this is a warning sign?
It’s the shore area. Can’t a change in the plates raise the land under a fresh water resevoir enough to have it perculate into the sea? There are fresh water pockets released under the oceans sometimes, which has been blamed for some ships sinking in the less dense fresh water.
I’m asking why the India government doesn’t consider this as one possiblity, if this could be a indicator as I believe it is. I want to know if they ever told the people this could indicate plates shifting, and why they ignore it if it is.
Please don’t tell me that tectonic plate shifts don’t cause tsunamis.
- If the movement of tectonic plates can displace salt water with fresh water.
- A cause of tsunamis can be the movement of tectonic plates.
- Does the up welling of fresh water on a shore merit watching out for a tsunami in the near future?
I’m not saying fresh water is going to transform into a tsunami. I believe it shows that a tsunami should be a worry if you go to the sea and the water is fresh. The fresh water would disapate if it wasn’t still coming in.
I can see that the fresh water floods could cause this. I stil wan confermation that this is or isn’t possibly a early sign a tsunami could occur in the near future.
I think if this happened, it would be recorded on seismographs.
I think (according to what I’ve read) this is not that unusual a phenomenon. It is located in a specific area. Located near a source of fresh water which authorities feel confident is the source of the fresh water influx. There have been heavy rains and a nearby lake has flooded over into the region. The local fishermen noticed the fresh water yesterday.
That’s NOT to say that an approaching tsunami couldn’t have similar results. But it would probably be on a larger scale. And would probably have made landfall before now or at least registered on seismographs somewhere.
There are definitely pockets of fresh water to be found in bodies of salt water. Both deep and shallow. IIRC there are fresh water pockets in the Atlantic that Columbus noted in his journal as having found in his quest. I know that the Amazon can push fresh water into the Atlantic as much as 200 miles when it’s swollen.
That’s not really unusual IMHO.
Could ground water seep from fissures into the local area? Of course it could, but like I said Occums Razor (and local authorities) suggest the incident is simply a matter of too much rain.
jimbeam: Cite for pockets of fresh (or at least potable) water within bodies of salt water, other than that found by river mouths?
I’ve heard of this happening when large pockets of gas are released, the bubbles can make the ship lose enough bouyancy to sink, but ships will still float on fresh water.
The problem is when they are loaded to the maximum capacity, and then they go lower in the water when the fresh water pocket occurs. They have to ballast the ships differently , when ocean vessels enter the Great Lakes system.
Can someone actually find a reliable cite for these “freshwater pockets”, please? I’ve found no evidence for them in my googling searches, save for only minor intrusions of freshwater here and there by landmasses via streams and aquafiers.
Besides the obvious river sources of fresh water.
Fresh water aquifers from the coast can extend for miles in to the sea, where fresh water is released and rises to the surface faster than it can mix with the salt water because of the different densities and temperatures.
Another source of fresh water is found at hot water vents. Most of which are too deep for fresh water to ever make it to the surface but in shallow areas the water will be fresh but probably not potable.
Fresh water currents can be found at the poles. Fresh cold water doesn’t mix with salt water and forms a river kinda like the gulf stream. As it warms it approaches the surface in streams but because it is constantly moving and is so remote I doubt you’d run across it on a weekend sailing.
Icebergs are another source of fresh water pockets that are occasionally found in the oceans, for obvious reasons.
As are frequent pockets of fresh water found immediately after storms. Salt and fresh water doesn’t mix as readily as you might think, especially when there’s a temp. difference involved.
BTW the Columbus reference was in relation to his “discovery” of the Amazon IIRC. (But he was over 200miles yet from the coast)
I’ll try to find you a decent site asap. This is just junk I remember from college and I doubt I have the texts. So hang in there, maybe I can find something for ya.
Sorry QAD I wouldn’t have brought it up if I thought it was that controversial. Man, I’ve been jackin around the salt for years and I thought this was common knowledge.
Problem is it’s not predictable except for the river and aquifer locations. A friend of mine said he hit a pocket coming back from Bermuda a couple of years ago. Fresh enough to drink…out in the middle of nowhere.
My old man was a sailor for years and he’s told me about it many times. I guess he was out to sea for a dozen years at least. He served in ww2 at sea and later worked a merchant ship for several years. anyway…he’s gone now. I’ll see what I can find.

Okay Qad so far what I’ve managed to discover is that global warming has the scientific community doing a lot of research on the subject but they’re not saying much publicly.
It’s called a “Surface Salinity Anomaly” and is caused by an influx of fresh water by various sources. The fresh water forms a layer or a current that doesn’t mix with the salt water. It occurs predominantly near polar water but is not confined to these areas. Continental regions have extremely cold water and fresh water has a tendency to build layers, pockets and currents at various depths from top to bottom. The salinity of these layers is on a scale that varies from practically drinkable to extra salty (heh).
As you know (I’m sure) the amount of fresh water in the oceans is basically what determines the avg. temp. of the oceans which in turn determines the weather pattern of the planet (is that circular or what?)
Anyway, try a search on “Surface Salinity Anomaly” and go from there. I’m not really satisfied yet with the articles I’ve found. They’re mostly pdf files and way too technical.
This is not a new phenomenon of course we’re just now starting to recognize that we have a real problem, accding to some reports.
If I find one I like I’ll let ya know.
IIRC the main one dad talked about was off the coast of Ireland many years ago.
and BTW Harmonious sorry about the hijack
that was supposed to be continental shelf regions have extremely cold water where fresh water accumulates…
