More than 90% of the key nutrients degrading the Mar Menor come from recirculated underground flows

A recent study reveals that over 90% of the Mar Menor's key nutrients degrading the ecosystem come from recirculated underground flows, not traditional sources like streams or groundwater. This discovery highlights a previously overlooked pathway of contamination and its impact on eutrophication episodes.
