[PT] Como já referimos em publicações anteriores, realizaram-se na semana passada as duas últimas saídas de campo: uma na praia do Carvalhal e outra na zona de S. Luís, ambas localizadas em áreas pertencentes ao Parque Natural do Sudoeste Alentejano e Costa Vicentina.
Relativamente à segunda saída de campo - praia do Carvalhal e Azenha do Mar - é importante salientar que esta zona, graças ao seu impecável estado de conservação, pertence ao Parque Natural do Sudoeste Alentejano e Costa Vicentina. É também uma zona de interface entre o mar e a terra, logo vai apresentar fauna e flora diferentes da 1ª saída, em que todo o ecossistema era típico de uma zona ribeirinha.
Na praia do Carvalhal, as cegonhas (Cicónia Cicónia) nidificam nas falésias, ou em rochas isoladas do mar, o que é um caso raro no Mundo.
Diz-se que há cerca de 65 milhões de anos atrás (época de extinção dos dinossauros) as enseadas eram o esconderijo de tesouros que alguns piratas escondiam. Como esta zona não era povoada, os piratas até tinham motivos para considerarem este um local ideal para esconderijo. Neste mesmo local, podemos observar estratos sedimentares horizontais inclinados.
A nível marinho, esta zona é rica em fauna do Norte de África, do Mediterrâneo e do Oceano Atlântico. Aqui existem baleias, tartarugas marinhas e cágados.
Na Azenha do Mar pudemos assistir à chegada de barcos de pesca, e por sua vez os resultados dessa mesma pescaria. Entre muitos outros, destacam-se as Fanecas, Raias, Espargos, Cavalas, Abróteas, Robalos, Safios, Peixe-Agulha...
A parte que está destacada na imagem ao lado é o resultado da brusca evaporação dos sais minerais, que formaram esta rocha calcária, situada bem no topo desta arriba. Em tempos, extraíam-se porções desta rocha para a produção de rodas de moinhos.
[ING] As mentioned in previous publications, were held last week the last two field trips: one in Carvalhal beach and another in the area of S. Louis, both located in areas belonging to the Natural Park of Southwest Alentejo and Costa Vicentina.
For the second field trip - Carvalhal beach and Azenha Sea - is important to note that this area, thanks to its flawless condition, belongs to the Natural Park of Southwest Alentejo and Costa Vicentina. It is also an area of interface between sea and land, will soon present fauna and flora of different 1st exit, where the entire ecosystem was typical of a waterfront.
In Carvalhal beach, storks (Ciconia ciconia) nest on cliffs, rocks or isolated from the sea, which is a rare case in the world.
It is said that there are about 65 million years ago (the time of extinction of the dinosaurs) inlets were the hideout of pirates hid some treasures. As this area was not populated until the pirates had reason to consider this an ideal place to hide. In this same area, we can see horizontal sedimentary strata inclined.
The sea level, this area is rich in fauna of North Africa, the Mediterranean and the Atlantic Ocean. Here there are whales, turtles and tortoises.
In Azenha Sea could watch the arrival of fishing boats, and in turn the results of that fishery. Among many others, there are the pout, Rays, Asparagus, Mackerel Forkbeards, Bass, challenges, Needle Fish ...
The part that is highlighted in the picture is the result of the sudden evaporation of minerals, which formed this limestone that sits on top of this cliff. At times, this portion is extracted for the production of rock wheels mills.

[ING]On the way back home / school, we could observe the human presence, through intensive agriculture. In many greenhouses we saw, to control the abiotic factors (humidity, temperature ...) artificially, which is not positive.
