Sixth Field Visit

I visited my research site for the last time on November 30 at 1:30pm. It was 40 degrees and beautifully sunny. There was some snow still on the ground from a few days ago. The length of the day was 9 hours, 16 minutes, and 15 seconds. When I was at my location, I saw and heard two ducks that were in the water still. Most of the plants are either dead or dying. There are very few leaves left on the trees. In my dissolved oxygen test, I learned that the water(6 degrees Celsius) is 32% saturated with oxygen.

Fifth Field Visit

I visited my field location for the fifth time on November 9. It was about 46 degrees and very overcast. The length of the day was 9 hours, 54 minutes, and 54 seconds. There were a few different kinds of birds chirping (see video at the end of this post). The stream was very flooded and the water was over the usual bank. Also, the ground around the whole area was much more saturated with water. I didn’t see any animals/bugs. Everything felt very cold and empty. My dissolved oxygen resulted in a 35% saturation of the water.

Fourth Field Visit

My fourth field visit was on October 27 at 11:00 am. At this time, it was 44 degrees. The length of the day was 10 hours, 28 minutes, and 56 seconds. It was crisp outside with on and off sun. There wasn’t any rain or snow, but it was breezy. I heard some birds chirping, saw the massive hive again, and noticed all of the leaves that have changed color. My dissolved oxygen test showed that the water was 43% saturated today. The saturation has increased from last time when it was only 40% saturated.

Third Visit

I went to my location for the third time on October 11 at 5pm. The length of the day was 11 hours, 14 minutes, and 30 seconds. The temperature was 74 degrees. It was beautifully sunny with a little breeze. The stream has become very flooded, and the water extends past the usual bank. I saw lots of leaves that have changed color. Also, I saw a squirrel and some birds. In my dissolved oxygen test, I found that the water had a 40% saturation of oxygen which was the same as the last time I tested it.

Second Visit

My second field visit was on September 27 around from 5:20pm until 6pm. The length of this day was 11 hours and 57 minutes. It was 74 degrees F at this point in the day, and it was quite windy. I noticed more plants this time than on my first visit. When I tested the water for dissolved oxygen, I noticed that the water is definitely getting colder as we head into fall and winter (last time the water was 19 degrees Celsius, and this time it was 15 degrees Celsius). I found that the dissolved oxygen levels were 4ppm and 40% saturated. Also, the swampy area that was very soft and filled with water the last time I was there was now more firm. I especially noticed the water this time as well. After doing the pond study, I looked at this water in a different way because I knew that there were tiny organisms in it that I couldn’t even see. On this visit, I didn’t see as many other organisms like toads, birds, or bugs. I did see and hear a flock of geese fly over. Also, I noticed how fresh it smelled at my location.

First Visit

IMG_0099

My location has lots of trees, some marshy areas, and a stream. My first visit was on September 8 at 6:50pm. It was 76 degrees with scattered clouds. The sun was out sporadically during my visit, and there was a slight breeze. The length of the day was twelve hours, forty seven minutes, and fifty five seconds. While I was at my location, I saw quite a few different elements of nature. There was a large yellow jacket hive(see photo below), various tracks, many different types of plants and trees, some flowers, a baby toad, and even a bunny. There were also many different sounds that I heard while I was in the woods such as birds chirping, water trickling, toads croaking, and leaves rustling. I really enjoyed this visit because it was a good time to just relax and enjoy God’s creation.

Sources Description

Source One: This site gives an overview of the importance of oxygen in water. It states that low dissolved oxygen levels can be harmful to aquatic life. Low oxygen in water can even kill fish and other organisms. This website also explains the effects of climate on water. The amount of dissolved oxygen that can be contained in water is dependent on the temperature of water. As the temperature decreases, the density of the water increases. This creates different layers of more dense and less dense water.

Source Two: The Department of Ecology’s site says that oxygen is crucial to the water functioning in it’s area. This site stresses the natural variation in amounts of dissolved oxygen in certain locations. It is normal for levels of dissolved oxygen to vary quite a bit even in the same body of water. This site also states that the summer is the hardest time for fish because the levels of oxygen in the water are lower.

This is a view of the very dense tree cover. You cannot even see the stream because the trees are so thick.
