When we visit a beach we usually come across several meters of sand that seems to have been placed there by the wind and that has no purpose in nature but something I learned as a scientist is that the planet has a reason for "everything", and here enter the dunes! did you ever hear that word? normally these accumulations of sand that we usually play with when we go to the beach have hundreds or even thousands of years there... Visiting this museum helped me learn a little more about these accumulations of sand and I will teach you a little about their function in ecosystems !👨💻🌏🧭
Cuando visitamos alguna playa normalmente nos topamos con varios metros de arena que parece que fue colocada alli por el viento y que no tiene ningun proposito en la naturaleza pero algo que aprendi como cientifico es que el planeta tiene una razon para "todo", y aqui entran las dunas! alguna vez llegastes a escuchar esa palabra? normalmente estas acumulaciones de arena con las que usualmente jugamos cuando vamos a la playa tienen cientos o inclusives miles de años alli... Visitar este museo me ayudo aprender un poco mas sobre estas acumulaciones de arena y te enseñare un poco su funcion en los ecosistemas!🧭🧠🚩👀🙇♂️
What are the Dunes?🚩🧠/ Que son las Dunas¿?🌏
As I mentioned before, the dunes are more than small accumulations of sand; on the contrary, they are very peculiar coastal ecosystems, which are home to a large amount of fauna and flora, for example, these ones here are from the Gaia area in the north of the country and it is famous Because it is home to 2 endemic species of plants and reptiles, the dunes are naturally formed by coastal winds pushed from the sea, which is why they are also called "sandes". Their composition is similar to that of coastal sand, they are composed of several layers of sediments, the dunes are interesting to analyze the behavior of the wind, for example if the wind is unidirectional then the dune will have a "C" shape
Como antes lo mencionaba las dunas son mas que pequeñas acumulaciones de arena son por el contrario ecosistemas muy peculiares costeros, que albergan una gran cantidad de fauna y flora, por ejemplo estos de aqui son de la zona de Gaia al norte del Pais y es famosa porque alberga 2 especies endemicas de plantas y reptiles, las dunas se forman naturalmente por los vientos litorales empujados del mar, por lo que tambien son llamadas: "medanos". Su composicion es similiar al de la arena costera, son compuestas por varias capas de sedimentos, las dunas son interesantes para analizar el comportamiento del viento pues por ejemplo si el viento es unidireccional entonces la duna tendra forma de "C"

Characteristics of the dunes🚩🧠/ Caracteristicas de las dunas🌏
The first plant that I come across while walking on the dunes is Otanthus maritimus and I find it quite interesting because it is exclusive to the Atlantic coasts, so it decorates and attracts many insects during its "blooming" season. Who would say that we can see many bees? and wasps in the dunes? nobody would believe this because literally the dunes are small deserts, but with this text you already know that there is much more life than you thought in the dunes! the two main components of a dune is either "calcareous sand or sediment", and where does the calcareous origin come from? Well, of course, the wind is capable of transporting these sediments hundreds or thousands of kilometers! a dune can measure from a few centimeters to hundreds of meters, it can be a few or thousands of years old! Can you imagine the negative impact of the government cleaning the dune beaches to establish premises or open spaces for tourist bathing spots???🧭🙇♂️🧠
La primera planta con la que me topo mientras camino sobre las dunas es Otanthus maritimus y me parece bastante interesante porque es exclusiva de las costas atlanticas por lo que decoran y atraen muchos insectos en su epoca de "floracion" quien diria que podemos ver muchas abejas y avispas en las dunas? nadie creeria esto porque literalmente las dunas son pequeños desiertos, pero con este texto ya sabes que hay mucha mas vida de lo que pensabas en las dunas! los dos principales componentes de una duna es o "arena o sedimento calcareo", y de donde sale el origen calcareo? pues claro del viento que es capaz de transportar estos sedimentos a cientos o miles de kilometros! una duna puede medir desde pocos centimetros hasta cientos de metros, puede tener pocos o miles de años! imaginas el impacto negativo del gobierno limpiando las playas de dunas para establecer locales o abrir espacios para puntos de baños turisticos???🌏🌅🤷♂️

Dune functions🚩🧠/ Funciones de las dunas🌏
We begin with the function that for me is the most important and that is to be a natural barrier to the ocean, that is, it prevents the waves from reaching beyond the coast and what negative effect does this have? actually a lot because off the coast we only have a biodiversity that can only carry out its biological functions with fresh water, the dunes are like large sediment reserves, in turn they function as a beautiful landscape that is quite pleasant for our eyes, as So? Isn't a beach with dunes and plants more beautiful than a deserted beach???👨💻🌅
Comenzamos con la funcion que para mi es la mas importante y es de ser una barrera natural del oceano osea evita que el oleaje llegue mas alla de la costa y esto que efecto negativo tiene? en realidad mucho pues fuera del litoral solo tenemos una biodiversidad que solo consigue llevar a cabo sus funciones biologicas con agua dulce, las dunas son como grandes reservas de sedimentos, a su vez funcionan como un hermoso paisaje que para nuestra vista es bastante agradable, como asi? acaso no es mas bonita una playa con medanos y plantas que una playa desertica???👀🧠🙇♂️
Here in the museum there is a small-scale model that forms dunes quickly, remember when I told you there are no dunes without plants? Actually the dunes and other natural objects are what allow the dunes to form since they form natural barriers and at that point the sediments accumulate, in the areas where there are no plants the sand only accumulates in layers but not in mounds! Another interesting fact that for a very "desert" area there is a wide variety of endemic plant species. I counted more than six species, one invasive!👨💻🤷♂️🌏
Aqui en el museo se exhibe una maqueta a pequeña escala que forma dunas rapidamente, recuerdas cuando te decia sin plantas no hay dunas? en realidad las dunas y otros objetos naturales son los que permite que se formen las dunas ya que forman barreras naturales y en ese punto se acumulan los sedimentos, en las areas donde no hay plantas la arena solo se acumula en capas pero no en monticulos! otro dato interesante que para ser un area muy "desertica" hay una gran variedad de especies de plantas endemicas yo conte mas de seis especies una invasora!🙇♂️🌏🧠
Protecting the dunes🚩🧠/ Protegiendo las dunas🌏
An effective way to stop sand erosion and dune destruction is to place wooden palisades along the dunes to replace the function of plants, which is to cut the wind and deposit sediment, if without these palisades the wind It would pass directly and instead the sediments would reach hundreds of meters from the coast, to maximize the deposit of sediments, the palisades are placed against the wind, that is, the concave area.👨💻🌏
Una forma efectiva para cortar la erosion de la arena y la destruccion de las dunas es colocar empalizadas de madera a lo largo de las dunas para reemplazar la funcion de las plantas, que es cortar el viento y depositar sedimento, si sin estas empalizadas el viento pasaria directo y en cambio los sedimentos llegarian a cientos de metros de la costa, para maximizar el deposito de sedimentos se colocan las empalizadas en contra del viento osea el area concava.🧠🙇♂️
A nice experience🚩🧠/ Una bonita experiencia🌏
Without a doubt, museums like these help us to reflect and understand the dynamics of these ecosystems that suffer a lot from their destruction due to anthropogenic factors because they are in places where thousands of people spend a year to use the beaches for leisure purposes, however the construction of elevated bridges helps to preserve them since people do not go through them! I really liked that the municipal chamber blocked the access so that no vehicle can also cause a negative impact on the dunes!👨💻🙇♂️
Sin duda museos como estos nos ayudan a reflexionar y comprender como es la dinamica de estos ecosistemas que sufren mucho su destruccion debido a factores antropicos debido que estan en locales donde pasan miles de personas al año para usar las playas como fines de lazer, sin embargo la construccion de puentes elevados ayudan a preservarlos ya que las personas no pasan por ellos! me gusto mucho que la camara municipal bloqueo los accesos para que ningun vehiculo pueda tambien causar un impacto negativo en las dunas!🌏🌅

Excelente trabajo. Nunca se me habría pasado por la cabeza que existiera un museo de dunas, me parece una buena manera de aprender su función y nos enseña a cuidar de ellas como elemento natural. Lo he disfrutado mucho. 🤗
