1.Fajardo lagoon usually glows when organisms in the water are disturbed
2.For the past nine days the water in the lagoon has remained dark
3.Biologists don't know why it's stopped glowing and are investigating
A glowing lagoon off Puerto Rico's northeastern coast has gone almost completely dark and biologists have no idea why.
The Fajardo Grand Lagoon in Las Cabezas de San Juan usually glows when bioluminescent organisms that live in the water are disturbed, yet they have not been visible for at least nine days.
Nearby construction work is thought to have caused disruption to the area, but biologists also believe a recent spate of bad weather could have caused the glowing lagoon to dull.
Another theory is the chopping down of mangrove trees in the area, to let larger boats into the lagoon and its surrounding water, could also have played a part.
'We have been compiling data,' Carmen Guerrero, secretary of the Department of Natural Resources said. 'There are a lot of factors that could be at play.'
The bioluminescent lagoon is often referred to as a bay and is a popular tourist attraction.
As a preventive measure, the government has temporarily suspended construction at the project for two weeks until scientists can figure out what is causing the problem.
Alberto Lazaro, president of the state Water and Sewer Authority, said he will evaluate scientists' findings before deciding how to proceed in several weeks.
Recent rains and a storm that are generating heavy waves is another possibility for affecting the lagoon's bioluminescence, continued Guerrero.
The Conservation Trust of Puerto Rico, which manages the lagoon and surrounding areas, collects water samples three times a week to record data including temperature, salinity and precipitation.
Scientists will analyse this data to help solve the mystery of the darkening lagoon.
It is not the first time the lagoon has gone dark. It went nearly dark for a couple of months in 2003 but the glow was restored before scientists could establish the exact cause.
I was just showing this to my Fiance as a place to possibly visit. I think they have recently stopped allowing people to get into the water because they wear bug repellants (poison) which kills the organisms. This is also known as Mosquito Bay.
This so reminds me of the movie Cocoon...

I'm wondering - it's also called Mosquito Bay? - are there a lot of mosquitoes there?

I agree - my whole post is ignorance - I'm asking questions.
I've never heard of this place.
Any info on the questions I ask would be appreciated.
