Early signs of recovery seen in the Mar Menor’s waters

A study about the current state of the Mar Menor accredits an improvement to the quality of the water in Europe’s largest salt water lagoon. The greatest tourist attraction of the region, along with the Calblanque National Park where you can find La Manga Club, is starting to show clear signs of improvement.

La Manga Club 22nd March 2017 – The alarm bells regarding the bad state of the Mar Menor rang last summer on all of the national bulletins, although always reassuring that you do not run a risk from swimming in it. An alarm that was made since the attempts to improve the state of the lagoon intensified. Today, the data that was supplied by Murcia’s council of Water, Agriculture and Environment was encouraging and showed signs of improvement for the Mar Menor. The government has moved these actions and measurements that are being implemented for the recovery of the Mar Menor to the European Commission, who have valued it in such a positive way.

The natural surroundings, in which you can find La Manga Club, is one of the most protected of the coast and efforts are not ceased in conserving the health of the two seas which encircle the resort.

The state of the salt water lagoon has been monitored for the past 29 weeks and the results obtained are highly encouraging. The oxygen, evaluated from last August until the beginning of this March, indicates that the parameter is increasing. Although with slight fluctuations, this surge remains. The improvement of oxygen levels is very important as it facilities the survival and development of wildlife and plant species.

The same occurred with the turbidity, which fluctuates slightly but tends to stay on the low end. The average data, as of 7th March, are the lowest that have been recorded. This monitoring has also analysed the chlorophyll levels against threshold values which too have been the lowest values recorded. For its part, the turbidity has decreased, which is indicated by less sediment in the water column and is accompanied by less phytoplankton as accredited to the reduction of chlorophyll.

Both improvements, along with the increase of transparency, favours the entrance of light and photosynthesis for the plants on the seabed, facilitating the recovery and general marine life. In turn, the proliferation of these plants, which forms an extensive seabed and filters the water, will increase the chances of reaching an optimum level of quality. Of the 10 measurement stations, the majority show visibility of more than 2 metres.

The data to do with the temperature is not bad on its own, but the high temperatures in winter are a risk factor, as it favours the increase in phytoplankton and consequently the eutrophication of the water.

With salinity going through something similar, low in December and staying more or less constant up until the beginning of March. It is not good that it decreases a lot as the Mar Menor is an oligotrophic ecosystem and contains species that are specially adapted to a high salinity. In any case, relatively normal levels are found.

From the Mar Menor Channel, there is the Information Service and Citizenship Awareness of the Mar Menor, under the authority of the council of Water, Agriculture and Environment who are optimistic, as the Mar Menor is demonstrating that it is an ecosystem that is alive and has the capacity to recover, but they are also wary because it is all down to us to conserve the health of the largest salt water lagoon in Europe.

Nature and sport

Thanks to its natural surroundings, La Manga Club has become a unique spot in Spain for training in resistance sport disciplines such as: triathlons and mountain biking. The temperate climate allows you to swim in open waters nearly all year round. There are many routes to practice these sports including through the Calblanque Natural Park, mount Cenizas, Portman or Sierra Minera, which all make up La Manga Club.
