[Coral-List] Reminder: Coral Spawning on the Web

Greetings, Coral-Listers,

    This is just a reminder of the message below, that we will be 
broadcasting live video images over the Web of a possible coral spawning 
event.  The camera will come on every ten minutes and remain on for ten 
minutes, from 7:02pm EST (00:02 GMT) to 5:32am EST (10:32 GMT, last 
lighting) tonight through Wednesday night.  One estimate of the expected 
time of spawning is around 10:30pm EST (03:30 GMT) tomorrow (Tuesday) 
night, but it could happen tonight  (Monday) or Wednesday night at any 
time...or not at all with this particular colony.

    You may be interested in a little description we have put together 
on coral reproduction, located at URL,


    Again, if the camera does capture a spawning event, we will try to 
put a better resolution digital video clip of the event on our Web Page 
for downloading.  As usual, the camera is also on all during the 
daylight hours, and is occasionally moved around for purposes of our 
Coral Literature, Education and Outreach (CLEO) program.

Greetings, Coral-Listers,
    As you can see from Dr. Alina Szmant's message below ("Alina Says"),  dated
February 21, 2003, spawning is anticipated for several species throughout
Florida and the Caribbean during selected days in August.  As  you may recall,
part of our Coral Reef Watch program at NOAA is the installation of
Web-accessible Coral Cameras at selected stations where viewing specific events
that can be witnessed are of value and interest to researchers and the lay
public, and where funding resources permit.  Thus, we would like to announce
that our colleague Dave Ward of the Caribbean Marine Research Center and
NOAA/AOML has positioned the St. Croix, USVI Coral Camera to point at a large
colony of /Montastraea faveolata/ in about 40' of water.  The camera has a
light on it that comes on for 10 minutes every thirty minutes beginning at
7:02pm (EST) and ending at 5:32am (last lighting).  Hopefully, we will be able
to witness the coral colony spawning some time between Aug 18-20, some time
between 9pm and 2am, with a high probability of Aug 19 as the likely date.
Hopefully, the coral will cooperate (it may be that that particular
colony does not spawn).  The URL for the Web Coral Camera is,


and click on "Live Web Cams" in the left-side list of links, then on
"UnderwaterCam."  You must have Windows Media installed on your computer to
access the images.  You can also open up the data stream directly in Windows
Media (and thus increase the size of the viewing window) using this URL:  


The camera is broadcasting at night all this week, and of course also during
all daylight hours.

    This effort is also part of our Coral Literature, Education and Outreach
(CLEO) program (http://www.coral.noaa.gov/cleo, currently under development),
under which we will also soon be providing educational modules concerning
coral bleaching and spawning.  Please note that we will also be recording a 
higher quality video stream (as opposed to that over the Internet) of the 
event which  will be downloadable (if they spawn) via the CLEO Web link at 
some time after the spawning.

Dear Carl (and others):

I feel like I should start an "Alina says... " column, and make it an 
annual feature.   I am glad to hear that I was accurate last year!

For summer of 2003:  Alina says...

Full moon of Aug is on Aug 12 at 4:48 am.

Acropora spp will spawn  sometime between Aug 15 and 17 at ca. 10:00 to 
10:30 am at  Florida latitudes and ca. 30-60 min earlier further south  
(ca. 2 hr after sunset)

Montastraea spp and Diploria strigosa will spawn Aug 18 to 20 at ca. 11 
pm or so in Florida and ca. 30 to 60 min earlier further south. (ca. 3 
hr after sunset)

In exchange for sticking my neck out once again,  I hope those of you 
lucky enough to be out there and observe spawning will email me back and 
let me know if your observations were on other dates.  We refine our 
estimates each year by gathering more observations.

Cheers, and don't step on the corals in the frenzy!

Alina Szmant

P.S.  I am not liable for any errors in my estimates, or any 
consequences of your spending your good time and money to be out there 
those nights.  However, if it works out, you owe me a beer for having 
saved all the time and money trying to figure it out for yourself.
