  1. CW: Blue Ocean Event Inevitable

    What else are we not talking about at government treaty gatherings until it's too late to avoid? For those of us who have a profound love for #coralreefs, this is a very sad moment during the anthropocene.

  2. Scientists Find Pristine Ecosystems on High-Seas Seamounts
    schmidtocean.org/scientists-fi

    "scientists observed 160 species on the Salas y Gómez Ridge that had not yet been known in the region and suspect that at least 50 of them are new to science. These are #squid, #fish, #corals, #mollusks, #SeaStars, glass #sponges, #SeaUrchins, crabs, and squat #lobsters, amongst others. They set a record for sighting the deepest-known #photosynthesis-dependent animal in the world: #Leptoseris, a wrinkle #coral."

  3. Coral mass spawning—one of nature’s great mysteries—is closer to being understood 🪸. Researchers tracked Acropora tenuis for a year, identifying 230 genes and inferring 4 biological processes that may prepare corals to spawn in sync. #coralspawning

  4. @andrekaiser @vincentritter A light version of the #ScribblesBlogDark immediately reminded me of the #CoralBlue (Light) version. Very similar colour palette. Even the dark version of CoralBlue looks similar.

  5. Scuba Diving between Cozumel and Playa de Carmen

    https://youtu.be/xqqas-nMK6k

    When planning a trip to the Yucatan, the decision of scuba diving Cozumel vs Playa del Carmen is the first hurdle. Each destination offers a completely different underwater profile. Cozumel is the undisputed king of drift diving and vibrant coral walls, while Playa del Carmen serves as the gateway to the hauntingly beautiful Cenotes and high-adrenaline seasonal encounters with Bull Sharks.

    The Impact of ‘Nortes’ on Your Dive Schedule

    December is prime diving season, but it comes with a catch: the Nortes. These strong northern winds can shut down the island of Cozumel for days. If the Mexican authorities issue a port closure (Puerto Cerrado), no dive boats are allowed to leave the harbor. This is where staying on the mainland in Playa del Carmen becomes a massive tactical advantage.

    Diver Intel: Always have a “Plan B.” During my stay, the ports were indeed restricted due to weather. Because I was based in Playa, I was able to pivot instantly to the freshwater systems. My previous dives at Cenotes Dos Ojos and El Pit highlighted why these are world-class alternatives—weather-proof, crystal clear, and visually stunning.

    Bull Shark Season: The Playa del Carmen Draw

    Between November and March, the sandy plateaus off Playa del Carmen become a hub for female Bull Sharks (Carcharhinus leucas). These sharks are attracted to the area’s nutrient-rich waters before they head to estuaries to give birth. Diving with these apex predators at 80–90 feet is a masterclass in buoyancy and calm air consumption. For tips on how I handle my camera during these high-energy dives, take a look at my guide on capturing large marine life.

    Choosing an Operator: Phantom Divers vs. Blue Life

    The experience you have with the Bull Sharks depends heavily on the dive shop’s philosophy regarding interaction. I used two different operators to see the contrast first-hand.

    Operator Methodology Cinematography Value Phantom Divers Attractant/Feeding High. The sharks are very close and active, allowing for incredible wide-angle and macro-detail shots. Blue Life Divers Natural Encounter Authentic. You observe the sharks from a distance as they cruise the sand. Ideal for those who prefer zero-impact diving.

    Cozumel’s Reef Health: A Brief Comparison

    Despite the convenience of the mainland, Cozumel’s reefs like Palancar and Columbia are in a league of their own. The verticality and sheer size of the sponges are superior to most sites on the Playa side. If you are looking for the “classic” Caribbean reef experience, Cozumel is worth the ferry ride. However, for a middle ground, the reefs of Puerto Morelos also offer fantastic coral density with much less boat traffic.

    Ultimately, the “best” side depends on your risk tolerance for weather and your desire for shark encounters. For me, the flexibility of Playa del Carmen wins in the winter months.
