  1. Lençóis Maranhenses National Park

    At first glance, the dune field of Lençóis Maranhenses National Park in northeastern Brazil looks like a desert. But this area’s rainfall tops 50 inches a year, exceeding Seattle’s typical amount. The result is white, crystalline sand dunes with colorful lagoons nestled between them.

    During the wet season, the combination of bedrock and clay beneath the dunes keeps the water from draining completely. It’s during the long dry months that the lagoons slowly seep and evaporate away, leaving the dune field mostly dry. (Image credit: M. Garrison; via NASA Earth Observatory)

  5. A vast stretch of sand meets the North Sea under a moody sky, creating an atmosphere of calm and solitude perfect for a seaside escape. Rolling sand dunes line the coast, adding to the natural beauty and providing shelter for wildlife along this tranquil part of the shoreline. The empty beach feels untouched, with only a few visitors enjoying the sweeping coastal views and the peaceful rhythm of the tide. Ideal for long walks and quiet reflection, it embodies the essence of #EmptyBeach #CoastalViews #MoodySky #SandDunes #SeasideEscape.

  9. In the Tidal Zone

    A lone shark cruises a sandy shoreline in the Maldives in this image from photographer Tim Burgess. Its path parallels the footsteps left by humans on the beach. Between the beach’s sand and the ocean’s deeper water, there’s a narrow stripe of sand ripples. Constantly formed and reformed by the crashing waves, these ripples act like miniature dunes. Any time a flat particle bed endures a passing flow above a critical speed, it will form ripples like these. (Image credit: T. Burgess/OPOTY; via Colossal)

  13. I am working on expanding my Eyesing visual tool with a sand dune formation algorithm. The existing infrastructure requires that I do it with shaders in Processing, which is quite a fun pickle considering the transport of sand grains across the lattice... In any case, it's not there yet, but the faulty outputs are already quite interesting.

  21. Engineer says 50 years of erosion research ignored by government and courts

    He might not be a household name, but Angus Gordon played a key role in preserving NSW beaches.…

  23. 💁🏻‍♀️ TIL: 🏖️📉 #California has lost roughly 60% of its coastal sand dunes since the 1850s, a loss of about 442 km².

    Researchers used historical #maps, aerial #photos, and #lidar #data tracked by #machinelearning to measure the decline. Most losses came from development, #erosion, and invasive grasses, but some dunes expanded by 15 km² .

  31. On the extensive sand dunes of the North Gare, south of Seaton Carew and near where the River Tees meets the North Sea.
    If you like big landscapes with big skies, this is a place worth visiting, especially at low tide.
    This area is part of the Teesmouth National Nature Reserve and it is Co Durham's most southerly stretch of coast.
    The impressive dunes hereabouts owe their existence to marram grass, sometimes called 'beachgrass'.
    Without this plant's important stabilising influence, the huge banks of sand would be at the mercy of the wind and waves.
    The root systems bind loose sand together, trapping windblown sand and creating sheltered habitats for other plants and wildlife.
