SEVENSEAS Marine Conservation & Travel Magazine

No. 135 · August 2026

Welcome to the August issue of SEVENSEAS Marine Conservation & Travel Magazine. This month we travel to Panama, a country that protects more than half its ocean on paper, counts 183,774 hectares of mangrove while estimating half the original cover is already gone, and has a UNESCO project in Darien working out why the trees died before it plants new ones. Fiji and Panama become the first governments to sign a pledge for the ocean’s twilight zone, the layer between 200 and 1,000 metres that feeds the fisheries above it and moves carbon into the deep. Dr Bill McGraw records colour changes in Porites corals at Seca Islands that he has not seen in fifteen years. Schmidt Ocean Institute finds two rare hybrid hydrothermal vent fields in the Atlantic’s Doldrums Fracture Zone, and the first footage of a barreleye in its own habitat. New research warns that great whites burn nearly four times the energy of cold-blooded fish to hold their thermal edge, and a warming ocean is turning that advantage into a liability. A Scientific Reports study finds fisheries harvesting Chinook before the salmon mature, shrinking both the fish and the runs that follow. Chris Bertish calls off his world-first solo Pacific crossing on the eve of departure, and sends the mission ahead without him. And much more, in one issue.

Feature Destination

Panama

Four stories from the isthmus: what the ministry counts, what the reefs are showing, what two governments have promised, and what a traveller should actually know.

Panama: A Conservation Traveller’s Guide to Whales, Reefs and Cloud Forest

Panama protects more than half of its ocean on paper. On the water the story is more complicated. Humpbacks, Coiba’s reefs, Guna Yala and the cloud forest, for travellers who would rather know than be sold to.

Panama Counts Its Mangroves, and What It Has Lost

The environment ministry puts national mangrove cover at roughly 183,774 hectares and says half the original extent has gone in fifty years. The figures are ministry claims, and the headline number has not held still.

Fiji and Panama Launch Global Challenge to Protect the Ocean’s Twilight Zone

Two governments are the first to join the Mesopelagic Zone Conservation Challenge, a voluntary pledge covering the water column between 200 and 1,000 meters. The layer feeds the fisheries above it, and almost nobody has agreed to manage it.

Increasing Intensity and Duration of Coral Bleaching Events in the Eastern Pacific Ocean, Panama

Dr Bill McGraw documents colour changes in Porites corals at Seca Islands, Gulf of Chiriqui, that he has not seen in fifteen years, and argues the current El Nino may prove the most destructive bleaching event yet recorded.

Deep Ocean Discovery: Two Rare Hydrothermal Vent Fields Found in Atlantic’s Doldrums Fracture Zone

A month-long Schmidt Ocean Institute expedition to the mid-Atlantic’s Doldrums Fracture Zone found two rare hybrid hydrothermal vent fields and captured the first footage of a barreleye fish in its natural habitat.

Built to Run Hot: The Overheating Squeeze on Great White Sharks

Warm-bodied predators burn nearly four times the energy of cold-blooded fish to hold their thermal edge. New research warns that a warming ocean is turning that advantage into a liability.

Harvesting immature Chinook is shrinking salmon and reducing future returns

A new Scientific Reports study finds ocean fisheries routinely harvest Chinook before they mature, shrinking the fish and future runs, and that fishing closer to the rivers could rebuild bigger salmon and feed Southern Resident orcas.

Chris Bertish Cancels TransCat Expedition: When Courage Means Saying No

After three years of preparation, ocean pioneer Chris Bertish called off his world-first solo Pacific crossing on the eve of departure. The mission behind it, a circular-economy classroom and tree-planting in Northern Kenya, is going ahead regardless.

Faster Ocean Models and a Major Carbon Correction Emerge From Five Years of Climate Research

Five years of Schmidt Sciences VESRI research have reshaped climate modeling, from an ocean emulator that runs hundreds of times faster to a finding that fire adds roughly 60 percent more carbon to the atmosphere than earlier estimates reflected.

Where the Trail Meets the Tide

A young travel platform is drawing notice for building its roster around outfitters that say they leave land and wildlife better than they found them. For readers who follow marine ecotourism, the logic is closer than it looks.
