	The glowing red ocean. Lose 30 kilos (of popups)

It seems that red tide has come to the waters off of southern California and now the water has a distinct red color to it. Red tide is cause by a sudden population boom of phtoplankton or algae, which turns the water a distinct red color. It is believed that the trigger for these events is when off shore currents bring an upwelling of nutrient rich water from deep in the ocean; with so much extra food in the water the phtoplanktons go crazy and reproduce so quickly that all of the water near the coast actually changes colors.

The really cool thing is that at night these phytoplankton are actually bioluminescent meaning they emit light at night time so people sitting on the beach at night can watch as glowing red waves crash on the shore.

I've heard about this but I've never seen it before. I couple of my friends called me today and we're planning on having a little bonfire at the beach tonight so we can watch the show. Have any of you seen this before?

Does red tide cause shellfish to become poisonous?

Nope. The beaches and red tide areas are usually off limits to harvesting during these time. Yet, I generally play it safe and avoid most uncanned shellfish during the fall...

we have red tide happen here on the Gulf Coast atleast once a year. If u have any respritory type problems dont go to the beach. A few summers back, I had an uncontrollable coughing spell due to Red Tide & had to stop fishing & go home......

If you dive, you can harvest shellfish below the first thermocline (typically 30-35 feet in SD waters), but that's pointless because the good stuff way deeper than the first thermocline (white abs, illegal for normal peasants but yummy and the pay is great), or else is intertidal.

The stuff you could harvest below the thermocline, when it's in season is primarily spiny lobsters, and they're in a food chain that goes back to plankton siphoners, so you do get an accumulation of biotoxins, as well as a contact hazard for some people from being in the water. Same thing with Sheepshead, which is a local game fish that feeds off of spinies - can't eat them either.

Sustained red tides severely **** up coastal ecosystems, and they can be a long time recovering.

Yeah, shellfish and crustaceans here are a joke, now that abs are no-take for anything other than scientific collection permits and all that's left is spiny lobster.

You don't want anything harvested off the California coast within the top two thermoclines anyway. Heavy metal toxicity from pollution is bad.

I was at the Marine Biology Laboratory in Wood's Hole Massachusetts one summer when a bioluminescent bloom came in to the shore. Swimming in it in the night was really cool, because the algae glow when the water is disturbed by waves or contact with your body. It was an almost psychedelic experience.

You can catch clams on most of the sandy beaches. Haven't abs been illegal to catch since the 1980's due to an infestation of an Asian bacteria which the local abs population had no immunity to?

If I remember correctly this parasite came from a ship carrying cargo from Asia and it has nearly wiped out the local abalone trade.

I'm supposed to go to Pacific Beach with my friends in two hours. I think I'm going to take a glass jar and some vinager with me because supposedly when you put the phytoplankton into a jar and then pore vinager into it they glow really bright. Of course that kills the plankton but the the bastards would do the same to me if they could, right?

It is kind of funny to be humbled by a single-celled eukaryote, but those single cells are complex though, some even have complex eyes, not bad for a unicellular critter. Thier shells are cool too (it seems like a lot of protists have cool-looking shells).

Golly, this brings me back. After swimming in the glowing water with our bodies illuminated in the strange blue light I walked the girl home and got laid for the first time in my life.

last week i went down to MOonlight beach in encinitas (near san diego..but you know that, oerdin" ..it was night and the water was glowing blue. ...in bursts as the tides broke. was that flourescent algae or plankton or something altogether different?
