SST's

[tunatamer4]

Box I hope you don't mind me posting this here, if there's a problem, please move it.

I put this on another site and couldn't get an opinion of any kind. I don't know, maybe it's just too much to think about.

Anyway, I, like just about everyone else have been relying on SST's to find the "fishy" water. Well being bored today I did a little digging on the suject and this is what I found.

Sea surface temperature (SST) is the water temperature close to the surface.

In practical terms, the exact meaning of surface varies according to the measurement method used. A satellite infrared radiometer indirectly measures the temperature of a very thin layer of about 10 micrometres thick (referred to as the skin) of the ocean which leads to the phrase skin temperature (because infrared radiation is emitted from this layer). A microwave instrument measures subskin temperature at about 1 mm. A thermometer attached to a moored or drifting buoy in the ocean would measure the temperature at a specific depth, (e.g. at 1 meter below the sea surface) — this temperature during the day is called temperature of the warm layer. The measurements routinely made from ships are often from the engine water intakes and may be at various depths in the upper 20 m of the ocean. In fact, this temperature is often called sea surface temperature, or foundation temperature. Note that the depth of measurement in this case will vary with the cargo aboard the vessel.


The way I read it is that the SST shots we are all so intent on getting are not all they are cracked up to be. Is the only true way to get a semi accurate temp from a thermometer since it is actually IN the water at a specified depth?

It's like according to this, theoretically, the temp at one foot COULD be, let's say 10 degrees cooler than the first 1mm.

So, the absolute best time to get a shot would be around 2 or 3am because the "skin" has had time to cool to the underlying water temp.
Am I correct? This is the first time I've actually dug into this and I'm kinda amazed.

Any thoughts?

i believe it was Capt Eddie from Venice who posted a week or so ago about catching a pile of wahoos in 56-59 degree dirty green water in the GOM. i believe he said the turd green water was only a layer just a few feet deep that lays on top of perfect 70 degree blue water. get your mess to fish a little deeper in the good water and, boom.....wahoos.

sure, we here in NC dont deal with the likes of the mighty mississippi river and it effects. but i found it interesting as hell. food for thought......

I THINK YOU ARE TRYING TO RE-DISCOVER THE WHEEL BRO JUST KIDDING


WHATEVER THE TEMP IS 10 FEET DOWN IS NONE OF MY BIZNESS....ALL I CAN DO IS TRY TO GET AN ACCURATE READING ON THE SURFACE....NO MORE NO LESS...AND I CAN TRULY UNDERSTAND WHY YOU HAD A LACK OF RESPONSE ON "THAT OTHER SITE" .....GEEZZZZ...

I GUESS WHAT I REALLY WANT TO SAY IS ....DUH HUH....THE GUT OF YOUR CONTENT IS A BIT CONFUSING TO A REDNECK LIKE ME

AND ....SINCE 1986 I THINK IT WAS...MAYBE 1987....I HAVE RELIED ON A MAN WHO HAS A DOCTERATE IN THIS FIELD....A CERTIFIED OCEANOGRAPHER....MITCH ROFFER.....

HE IS THE PIONEER....AS FAR AS I AM CONCERNED HE WAS AND IS THE MAN WHEN IT COMES TO INTERPRETING SEA SURFACE CONDITIONS...HIS NETWORK OF SOURCES IS EQUALLED BY NONE

I GUESS I AM A BELIEVER IN HIM....THE WINNING CHECKS I HAVE RECEIVED AS A MATE IS PROOF IN THE PUDDIN...

I'm not saying we shouldn't rely on them anymore, but the fact of the matter is that if a sat. shot only measures a couple of millimeters deep, how accurate is it overall?

For example, I was looking at an inshore spot the other day. At 6:30am the water temp on this ledge was 46 and change. I checked it later that day and the 3:30 shot was at 55+. the next shot showed it to be 47. There were no eddies visible on the loop to influence the temp.

Now I know that the river water was at 48 degrees because we spent the day on it crabbing, so the outgoing tide had nothing to do with the temp rising nine degrees.

Ah S%@*, I'm just gonna go pour me some Southern Comfort in my bottle of Mountain Dew and let my brain turn to mush.

Atta boy... come on back to us buddy. Its warm and cozey here in mush land.

Seriously though....your thoughts make a lot of sense and certainly worth some experimentation. It should not be too hard to compare on your days out with a simple drop therm.

If you are so motivated ... please do keep us posted on your results. I would love to know if you find warm water under cold or vice versa!

I use SST shots to show me breaks more than exact temps as they fluncuate daily, a break will get me more in the right area than just worrying about exact temps, I personnelly have been more concerned with Chlorphyll info. on the Left Coast as it seems alot more important out here as a few degrees of Temp if I see the right break with the right chlor. shot it usually puts me right on top of the fish constantly!!!PEACE

The water temp below the surface still affects the surface
temp. If the water temp 10 feet down is 60 in one area and
it abuts an area that the water temp is 70 at 10 feet down,
don't you think that would affect the surface temp in each area. Of course it would.

One thing that has not been mentioned here that is a very important puzzle piece is sea surface height, sea surface height depicts cold core cyclonic rings and warm core anticyclonic rings. Roffers and other professional fishing forecasters base their advice on the collective information available through sst, sea surface, chlorophyll, bathymetry as well as some other available data. Each one alone is useful, but the conglomeration of all of them together is much more powerful.

Not to jack your thread, you have asked a very interesting question.

I have been looking at a couple different services and was looking for advice for which one to go with? Some are free, some are moderatly priced and one looks really good but very expensive. What do I do? spend $99. on terrafin or 2,000.00 on roffers? wait, I dont have 2k to throw down...

Thanks for your HELP!

Roffers is expensive but it is the best, they also communicate with commercial fishermen affiliates if they are in the area. They will also give you several waypoints to go to, I dont know anyone else that does that. Im not familiar with the service you mentioned but most of the inexpensive ones supply you with the data and leave it up to you to decide where to go. You can also purchase roffers on a trip by trip basis, I believe you need to call them the morning before the morning you plan on fishing. Another advantage of roffers is that satellite data is often inconclusive because of cloud cover, roffers will look at surrounding areas and use mathematical equations to determine conditions in the waters you plan on fishing. If you have a couple 100 dollars to throw at the situation you may want to purchase the cheap service and periodically order a roffers to see if it makes a difference, I bet that it will.
