Spring Warming Triggers Bleaching Alert on Costa Mar Reefs

Water temperatures at the northern monitoring stations have climbed to 29.8 degrees Celsius, nearly two degrees above the May average recorded over the past decade. The Costa Mar Reef Monitoring Network issued a yellow alert on Friday, signalling the onset of thermal stress across the region's three main reef systems. The alert does not yet restrict diving operations, but it has prompted the network's scientific director to recommend a voluntary reduction in daily dive quotas.

Tourism operators along the Puerto Azul coast have begun notifying guests of the conditions. The region's eco-tourism sector depends on reef health as its central draw, and spring warming has become a recurring concern as the rainy season approaches. Several dive cooperatives have already begun spacing their expeditions to reduce pressure on the most thermally stressed zones.

The network's latest readings come as federal policymakers in Meridian continue to debate the balance between conservation budgets and tourism promotion. Costa Mar's marine economy generates roughly eighteen percent of the region's gross product, a figure that has drawn scrutiny from both tourism-industry representatives and conservation advocates in the Federal Assembly.
