The salty lagoon registers an average of 29.14ºC compared to 31.25 in the last week of July, when the peak was reached since there are records
The drop in temperature of the Mar Menor “favors an increase in the concentration of oxygen in the water in the medium term,” explained the spokesman for the Monitoring Committee of the salty lagoon, Emilio María Dolores. A parameter that the control body considers positive, since it reduces the risk of anoxia in the ecosystem, which is currently in a stable situation, according to the latest controls. “The oxygen levels give us a certain peace of mind,” said María Dolores after the meeting that the committee holds every two weeks with the president of the Autonomous Community, Fernando López Miras, to inform him of the evolution of the state of the lagoon.
Specifically, the decrease has been two degrees, from the 31.25 average temperature that the water reached during the last week of last July -the highest recorded since there are measurements- to 29.14 that the thermometers They have scored on average in recent days. Despite the fact that this downward trend is expected to continue, the Mar Menor Monitoring Committee shows caution and concern about the possibility that the high temperatures that have been registered in both the Mar Menor and the Mediterranean cause torrential rains that could seriously harm the ecosystem. as it is a “discharge basin”, as defined by the spokesman for this control body. “We are concerned about the effects that a DANA may have on the Mar Menor. You can’t fight against these natural issues, but you can fight against this continuous bleeding that is entering », he said referring to the discharges from the Albujón boulevard. “Water shouldn’t get in because it hasn’t rained for months,” lamented María Dolores.
“We are concerned about the effects that a DANA may have on the Mar Menor,” says Emilio María Dolores
16,562 tons of algae
Regarding the presence of algae, the spokesperson for the Mar Menor Monitoring Committee estimated that 16,562 tons were withdrawn this year, which is equivalent to 345 tons of nitrogen -which represents 37% of the total that has entered- and 11, 5 tons of phosphorus, which translates into the elimination of 180% of this mineral. An action that has prevented the proliferation of areas of mud and mud, as explained by María Dolores. “A very important figure that is having a very positive influence on the ecological state.”
The rest of the parameters that mark the evolution of the ecosystem remain stable. Values that are controlled through the two measurement buoys installed in the Mar Menor that give information every six hours on the state of the salty lagoon -and that will double in the coming weeks- and that show “good data for the time of year we are in”, according to the Committee’s spokesperson, who has been at the head of the Autonomous Community Fisheries Service for 25 years.
Regarding the current turbidity of the 135 square kilometers that the Mar Menor has, Emilio María Dolores assured that transparency has improved in general terms compared to the previous week due to the latest winds that have blown from Poniente, although he acknowledged that in Los Urrutias and in Los Nietos “the water is less clear.”
They investigate whether the discharge on the Galúa beach comes from the hotel
Technicians from the Ministry of the Environment appeared this Thursday morning at the Galúa de La Manga beach, in the municipality of Cartagena, to collect samples of a spill of water into the Mediterranean Sea denounced the day before yesterday by the Municipal Citizen Movement Group (MC ) in the City Hall of Cartagena, and thus be able to determine its origin and chemical composition. One of the lines of research that is being considered is that the liquid from a broken pipe located between some rocks could be water from the air conditioners of the hotel that bears the same name as the beach. However, and in the absence of the conclusions of the investigation, which will still take a few days, what the Ministry maintains is that it is not wastewater. If the hypothesis that it is a pipe coming from the hotel is confirmed, the establishment must channel the pipe correctly to the storm sewer network.
This newspaper contacted the Hotel Galúa this Thursday and asked to speak with a person in charge to find out his version, but he preferred not to make a statement.
Regarding another possible spill near the beach of Las Gaviotas de La Manga, in the municipality of San Javier, the Councilor for Public Services, María Dolores Ruiz, insisted that it was not wastewater, but an air bubble that came out of a tube that is only used in the event of a ground fire network collapse. The mayor assured that it is empty and was at the time of detection, that it is already anchored to the bottom and that no other pipe is broken and pouring dirty water into the sea.
