Parangtritis sand dune

Parangtritis sand dune or Parangkusumo sand dune is the accumulation of sand due to gusts of wind along the coast of Parangtritis in Bantul Regency, Yogyakarta Province, Indonesia. Sand dune has several types including barchan or crescent, longitudinal, transverse and parabolic.

Things that affect the creation of sand dune are the volcanic activity of Mount Merapi and Mount Merbabu, the Opak River and the Progo River which carry volcanic material, and wave power from the south coast of Java.

Dlium Parangtritis sand dune

The process of forming sand dunes in Parangtritis begins with the eruption of Mount Merapi and spits volcanic material in the form of hot clouds, dust, sand, hot lava, cold lava, and rocks that flow into the rivers of Opak, Bedog, Boyong, Gendol, and others.

The volcanic material flows towards the Opak River estuary and enters the sea. Large ocean waves carrying material are deposited along the coast. Volcanic material in the form of sand is then carried by the wind and piled up somewhere.

The requirement for the creation of sand dune is a gentle beach, sand material supply, sea waves that throw sand from sea to land, strong currents along the coast, and strict differences in the dry season and rainy season.



Sand dune is often seen along Parangtritis Beach to Depok Beach in miles. This is the geoheritage area as a place protected by the United Nations Educational Scientific Cultural Organization (UNESCO). Residents around it use it for tourism including photo spots and sandboarding that only exist in Southeast Asia.

The Parangtritis sand dune once carved history by the cempaka tropical cyclone. The cyclone had a bad impact, but it also brought goodness to the visitors of Parangtritis Village where they found an oasis in the middle of the desert. This oasis phenomenon occurs in an area called "dune slack" or valley of sand dune.



Sand dune is only owned by Mexico and Indonesia, but the sand dune in Parangtritis has a barchan type that is only in Indonesia. Every day coastal communities move small sandbanks that block houses, road access, and agricultural land.

The tourists feel the sensation of skating from the top of the hill using a board for sandboarding. Some surfboard rental services offer prices varying depending on the duration of time. IDR 70,000 is enough to rent a board for unlimited sandboarding, including a guide who teaches how to glide over sandbar.

A deep-sea isopod Bathyopsurus nybelini adapted to feed submerged Sargassum algae

NEWS - Incredible footage shows a marine species, Bathyopsurus nybelini , feeding on something that sinks from the ocean’s surface. Researchers using the submersible Alvin found the isopod swimming 3.7 miles down using its paddle-like legs to catch an unexpected food source: Sargassum. Researchers from Woods Hole Oceanographic Institution (WHOI), the University of Montana, SUNY Geneseo, Willamette University and the University of Rhode Island found the algae sinking, while the isopod waited and adapted specifically to find and feed on the sinking nutrient source. The Sargassum lives on the surface for photosynthesis. The discovery of a deep-sea animal that relies on food that sinks from the waters miles above underscores the close relationship between the surface and the deep. “It’s fascinating to see this beautiful animal actively interacting with sargassum, so deep in the ocean. This isopod is extremely rare; only a handful of specimens were collected during the groundbreaking Swedis...
