Rising Water Column One Mile Out from Lighthouse Point ,FL

I was out sailing today and saw a strange water disturbance that I have not seen before. It was located about one mile due east of Lighthouse Point, FL and looked like a rising water column about 75-100 feet across.
Please see the attached photos.
Does anyone know what this is? I have lived here for 29 years and don't ever remember ever seeing it before.

Some years ago there was a report of vertical water jets and holes appearing at random in the sea around a sailboat in this general area. It was speculated that this was due to a cold sea water layer over a much warmer sea water layer. When the cold water sank it would form a hole and when the warm water rose it would form a jet. It could be what you observed but to a lesser degree. Then again it could be just a tide/current generated up-swelling.

Methane? Probably too much TV ...Actually not really sure, but after thinking about it, we have those kind of swells up here in the PNW, usually in tidal rips...could also be something under the water where currents collide etc. I'll be waiting to see what other takes on it are.

It might be a resurgence fresh water from an underwater spring. There is one near St. Augustine, Fl that looks just like this, and is actually marked on charts.

A sub nose down? Heck I'm happy as long as it doesn't swallow me.

Serendipity strikes again! Just found this article at Science Daily. The last sentence may be germane to the question at hand.

Tides, Earth's rotation among sources of giant underwater waves

Common sight/experience around here (PNW). Shallow spot where curretns produce upswell. Did a 360 in one today in the tender.

I know exactly what this is, having owned and operated a commercial dive boat in this area for 10 years- this happens all the time but is only visible when the water is like glass, south east Florida has a North/ or south current "most of the time" sometimes as fast as 3 knots , sometimes this current changes direction and when it hits the reef ledge or wall-some as high as 25- 75 feet vertical the water is deflected and goes up- there are many of these all along south east Fl, Im willing to bet the depth of the water you found this in is between 90-170 feet, I use to drop divers off on these spots all the time and have dove them myself

Don't know your exact location, but note on EarthNC viewer there appears to be an outfall about a mile off Hillsboro Inlet, and another one a bit further south. Warm fresh water piped into relatively cold salt water would produce such an effect.

We saw the same thing off Mazatlan, Mexico, but it was "chunky".
