Swimming in the red tide at night was on of the most amazing experiences i will ever have. To see a phenomenon is on thing. . . To be in one (fully) is like a dream come true.

Coronado Dog Beach did not have red tide Aug. 11, 2005, but yesterday the 15th was very thick. Seems it was in Encinitas last week and it is moving south. There is no odor, but really gross looking in day, lovely at night. I am concerned about the v. cholorae. My sons have continued to surf and my dogs have been under the waves extensively. I have always heard that the red tide is not harmful, but now it seems that has changed. I would like a clear answer if possible. It is awesome at night and great fun to swim in – with grunion running next week it should be wonderfully interesting. Thanks! Also I always learned that green water was high in phytoplankton and brown or red for zooplankton. Am a wrong on that too????

I’ve seen this effect for years, but went out in the surf on my board for the 1st time last weekend. The effect 100 yards offshore is 10X more spectacular! My arms paddling was an incredible light show!

I was in Oceanside this past week, and it was the most amazing thing I have ever
seen! I was captivated for hours at a time at night, I just could seen to tear my eyes away from the beautiful display!

I saw the red tide glow last night at Corona Del Mar in Orange County. It
was so amazing. It was very romantic alone with my husband. Very
beautiful.

The red tide phenomenom is perplexing to those of us who are not marine biologists. I was always told they are not dangerous; and now v. cholerae is a possibility. Tthat sounds ominous; especially because my 12 year-old was boogie-boarding in a serious red tide today in Northern Baja(K 22). It is a beautiful site to behold at night. I just worry about keeping my kids out of the water while on vacation in Baja next week. Thanks for the great pictures. C

Scripps Instutie of Oceanography states that vibrio cholerae is present in San Diego red tide. Therefore, the tide is dangerous to human beings. Please be cautious

I asked for a link on this:

sure. here it is. thanks for asking. AEM stands for Applied and
Environmental Microbiology. Here is the quote that worries me.

“Under the conditions tested, free-living V. cholerae was able to reach
concentrations per milliliter that were up to 3 orders of magnitude higher
than the known minimum infectious dose (104 cell ml-1) and remained viable
under many conditions. If applicable to the complex conditions in marine
ecosystems, our results suggest an important role of the growth of
free-living V. cholerae in disease propagation and prevention during
phytoplankton blooms.”

I leave the EXIF data public on my photos; just click the More properties link under the Additional Information on the right side of each photo’s page.

It was a really challenging shoot, given the almost unpredictable, short-lived, moving subject in the dark: lots of playing with exposure and ISO, while also hoping to click the shutter at precisely the right time. ‘Twas fun, though — it was just amazing to be there.
