On 11th June 2014 we were driven by a fisher boat to the Island of Spiekeroog where we went for a walk later. 

On the boat we were fished craps and other types of fishes and we analyzed the size and the numbers. We wrote the results on a paper with the help of the information paper and the guide. We also drove next to an island where we saw seals in the sand. We looked at the seals with binoculars.

 

 

When we arrived to the island we started to walk and to took water probes from different water-springs ( Sea, „Löschteich“, lake „Kurpark“  ). We were guided by the biologist Carsten.

 

He showed us the island and told us something about the village and the inhabitants. For Example, he said that the at first the village was in another part of the island but in consequence of the water and storms, the village had to move to another place. He explained to us that the dyke on which we were walking protect the village from the water because it is higher than the village.

 

 

Our group worked together to get results of the amount of salt, temperature, oxygen, pH-value and electric conductivity in the water. We had 2 machines to measure these results. One for the salt and the other one for the rest.

After we had taken the probes from the water, we took a walk across the village „Spiekeroog“ to the laboratory, where we analyzed the probes in groups. 

 

 

We compared our results with the machine results. The biologist told us, we would have to be more precise in order to get exact results. Nevertheless we could see that there was more salt in the ocean than in the “Löschteich” or “Kurpark”. In the Ocean was the most contamination.

After that we had some free time and then we went back in the harbor. It was a good experience and we have learned that we must be very careful with the water because it can change its qualities because of our behaviour.
