Vuelvo en espa/nol. Comentaba en el articulo anterior de la intencion del 'Top Kill' para controlar el derrame de BP en el Golfo de Mexico. Entonces en la discusion del tema de por que New Orleans no se muda ya de ese punto tan malo fue que me recorde del tema de hoy.El tema de hoy tiene que ver con hipoxia, o poco oxigeno disponible...y es critico en el area de Louisiana y Mexico. Y debe amarrar bastante bien a lo que esta pasando cortesia de la plataforma de BP.

Primero los muros de contencion y diques que fallan
Seguimos con Katrina

Pero se quedo fuera uno que es preocupante a nivel mundial:
La gran marea roja
Grey Snappers, like all other Gulf species, prefer water with abundant oxygen and food.
The Dead Zone provides neither.

Prohíben consumo de mariscos por marea roja en noreste de México
Las autoridades sanitarias del estado de Tamaulipas, en el noreste de México, prohibieron el día 18 a los turistas de la playa Bagdad consumir mariscos ante la posible presencia de marea roja en las costas del Golfo de México. El jefe de la Tercera Jurisdicción de la Secretaría de Salud, Víctor García Fuentes, informó este domingo en un comunicado que se realizan estudios de laboratorio para verificar si la muerte de cientos de peces en esa zona fue provocada por ese fenómeno natural. "Todo parece indicar que es marea roja. Nada grave, ya que es de menor intensidad que en otras ocasiones, pero hay que tomar las debidas precauciones" para evitar posibles enfermedades, señaló. Garcí Fuentes dijo que las autoridades del estado mantienen comunicación con los vacacionistas que asisten a esa playa para que eviten, a toda costa, consumir mariscos crudos, como ostras, mejillones y almejas, hasta que se confirme que haya pasado la marea roja. El funcionario exhortó también a los pescadores de esa región a no ofrecer productos del mar a los turistas. Incluso comentó que algunos pescadores han manifestado malestares ligeros como dolores en la garganta, lagrimeos y fluidos en fosas nasales debido a esa fenómeno natural. Para ello, señaló, se han girado instrucciones de que se atienda en el Hospital General regional a toda persona que sienta molestias físicas mayores ante una posible intoxicación por el consumo de estos productos.

La Marea Roja Ocurre Cuando Hay Muchos Nutrientes (la descarga del Missisipi), altas temperaturas (Golfo de Mexico son aguas calidas) y una poblacion de bacterias. Una explosion en poblacion causa grandes cantidades de algas. Al bajar el oxigeno disuelto del agua por el agua caliente entonces condiciones anoxicas y todo muere. Literalmente, el mar muerto...por hipoxia.
In a marine system with two distinct water layers, over-production by algae may cause hypoxia, disrupting bottom communities and causing mobile organisms to leave the area. Modified from National Center for Appropriate Technology, www.ncat.org/nutrients/hypoxia/hypoxia1.htmVarios articulos aqui:

Red Tide
What is a Florida red tide?
A red tide is a higher-than-normal concentration of a microscopic alga (plant-like organisms). In Florida, the species that causes most red tides is Karenia brevis. This organism produces a toxin that can affect the central nervous system of fish. At high concentrations (called a bloom), the organisms may discolor the water. However, red tides are not always red. They can appear greenish, brownish, and even purple in color. The water can even remain its normal color during a bloom.

Is red tide a new phenomenon?
No, it is not a new phenomenon. Red tides have been documented along Florida's gulf coast since the 1840s and probably occurred much earlier. Fish kills around Tampa Bay were mentioned in the logs of Spanish explorers.

Can red tides be predicted?
Currently, red tides can’t be predicted, but researchers are investigating the possibility. The effects of a red tide (e.g., dead fish and respiratory irritation in people) depend on the location and concentration of the red tide microorganism at a given time. The effects also depend on wind speed and direction. It is important to realize that many people still enjoy the beaches during red tides. Respiratory irritation and dead fish are not always present.

Do red tides occur anywhere else?
Yes, red tide organisms occur elsewhere. Although the organism that causes Florida's red tide is found almost exclusively in the Gulf of Mexico, blooms have been found off the east coast of Florida, and a bloom was detected off the coast of North Carolina in 1987. Scientists believe the Florida Current and Gulf Stream Current carried K. brevis out of the Gulf of Mexico, around South Florida, and up to the Carolina coast. Other types of microorganisms cause different kinds of red tides (now called harmful algal blooms) in other parts of the world as well.

How is red tide related to respiratory irritation?
People experience respiratory irritation (coughing, sneezing, and tearing) when the red tide organism (K. brevis) is present along a coast and winds blow its toxic aerosol onshore.

CAUTION: People with severe or chronic respiratory conditions (such as emphysema or asthma) are advised to avoid red tide areas. Generally, symptoms are temporary. Once exposure is discontinued, symptoms usually disappear within hours.
http://www.science-house.org/nesdis/algae/background.htmlEse tema es preocupante a nivel global puesto que ya otras areas tienen situaciones similares, lo que afecta la pesca MUNDIAL. Asi que este derrame simplemente acelera las acciones que hay que tomar con la zona. Esa remediacion es otra historia, quedemonos por ahora con el Plug.
Hercolobus nos va a comer...

Apocalipsis 16, 3-4
Y el segundo ángel derramó su copa sobre el mar, y se convirtió en sangre como de un muerto; y toda alma viviente fué muerta en el mar.
Y el tercer ángel derramó su copa sobre los ríos, y sobre las fuentes de las aguas, y se convirtieron en sangre.
Los dejo con Red Rain de Peter Gabriel.
Peter Gabriel - Red Rain
red rain is coming down
red rain
red rain is pouring down
pouring down all over me
I am standing up at the water's edge in my dream
I cannot make a single sound as you scream
it can't be that cold, the ground is still warm to touch
this place is so quiet, sensing that storm
red rain is coming down
red rain
red rain is pouring down
pouring down all over me
well I've seen them buried in a sheltered place in this town
they tell you that this rain can sting, and look down
there is no blood around see no sign of pain
hay ay ay no pain
seeing no red at all, see no rain
red rain is coming down
red rain
red rain is pouring down
pouring down all over me
red rain-
putting the pressure on much harder now
to return again and again
just let the red rain splash you
let the rain fall on your skin
I come to you defences down
with the trust of a child
red rain is coming down
red rain
red rain is pouring down
pouring down all over me
and I can't watch any more
no more denial
it's so hard to lay down in all of this
red rain is coming down
red rain is pouring down
red rain is coming down all over me
I see it
red rain is coming down
red rain is pouring down
red rain is coming down all over me
I'm bathing in it
red rain coming down
red rain is coming down
red rain is coming down all over me
I'm begging you
red rain coming down
red rain coming down
red rain coming down
red rain coming down
over me in the red red sea
over me
over me
red rain
red rain is coming down
red rain
red rain is pouring down
pouring down all over me
I am standing up at the water's edge in my dream
I cannot make a single sound as you scream

Este articulo esta cabron en cuanto a toda la cancha cubierta. Requiere tiempo y digestion. Mucho que masticar.
Estamos jodidos irremediablemente.
Siempre es un grato placer pasar por aqui. Esto de entender poco a poco la totalidad real del entorno, biodiversidad no ES COCONUT SKIN.
Suerte y exito..Agradecido como lector disidente y contrario por compartir esto.
