Reef stress signals shift as warming waters persist

The Costa Mar Reef Monitoring Network reported this week that mangrove stress signals have shifted into a new pattern, with the Punta Negra station recording sustained temperatures 1.2 degrees above the seasonal average and the Bahía Profunda monitoring post detecting nutrient-level changes consistent with inland runoff. The readings, taken across five coastal stations between Puerto Azul and the southern reserve, suggest that the region's shallow-water ecosystems are responding to conditions that extend beyond the usual thermal fluctuations of the dry season.

The shift comes as the Federal Hydro Authority manages reservoir levels during peak demand, a period when Costa Mar's hundred-percent hydroelectric grid typically draws down storage to supply electricity to the broader federation. The relationship between inland water management and coastal water chemistry has long been a point of study for the network, but the current readings appear to show a tighter coupling than previous years.

The network's director, Dr. Elena Morales, told the bureau that the patterns are not yet alarming but warrant closer attention. The findings will be presented to the Marine Ministry in Puerto Azul next week and are expected to inform federal discussions about seasonal water-release protocols.
