Water Sampling using the old method

Once a month we need to be sure that every tool is still in good order.It was interesting to see the different results and if the new method is more accurate, we got exactly the same number for the water temperature: 11.2 Celsius. When we went to get the water in the bucket we heard a splash and first thought that it was a sea otter because it was very quick but just following was the most adorable creature: a small harbor seal.It might be 50 cm at the most. That one has not been born long ago! Happenings never stop on Race Rocks!
