Danger of anoxia in the Mar Menor

Mar Menor (Murcia)

The Lagoon Ecology working group, which met in the presence of the Regional Minister for Water, Agriculture, Livestock, Fisheries and the Environment, has determined, according to its members, that “we are once again facing a critical situation in view of the weather forecasts of calm in the coming days, and in general throughout the week, so we are facing a new episode of anoxia which, as the data shown above show, is already in an advanced process”, indicated Antonio Luengo. “This episode would be similar to those experienced recently as it is located in the southern basin, with a tendency to accumulate organic matter and masses of anoxic water at the bottom of the southern arch, as was observed in the episode last August,” Luengo said. The councillor explained that, given the forecast “of a possible worsening of the problem in the very short term, which could be hours, days or weeks, and given the similarities with the last episode of anoxia, it is necessary to take urgent measures to prevent, or at least mitigate, the loss of stocks and biodiversity that could compromise the recovery of the system”. “This action, controlled in time and reversible, on the flow of exchange in this channel, seems to be one of the few urgent measures to be taken today to alleviate the devastating effects that a new episode of anoxia would have on a system already greatly altered by the last episode of just over a month ago”.

The letter demands from the General Directorate of the Ministry “the necessary actions to alleviate the damage that this new episode of anoxia could cause on an ecosystem that is in a fragile situation, whether the urgent actions that have been proposed by the Autonomous Community or those recommended by the Spanish Institute of Oceanography for urgent application, requesting that it informs of the urgent measures that will be implemented as soon as possible”.
