Long Term Trends And Seasonal Trends On Phosphorus At The Bosherston Lakes, South West, Wales

Through our research we aimed to determine if there were any differences in water quality of both the north and south forks of Strawberry Creek. As time progresses and the environment changes it is important to keep track of how certain species are being impacted by these features, and how they cope with change. We hypothesized that due to the lack of pollution, the south fork will promote a greater diversity of macroinvertebrates. This was due to the fact that there was less runoff and trash that could be introduced to the water in the south fork, than there was in the north fork. We gathered data by analyzing the different organisms living in both forks. We collected a total of fifty vials composed of five organisms from each fork, and inspected them under microscopic view. After gathering data and identifying the different kinds of organisms living in the different forks we assessed whether the organisms from the samples could live in high or low resolution water. We also took a t-test to assess the probability of these differences being due to relevant factors or by chance. Our major findings suggest that organisms in the south fork showed a higher demand to living in cleaner water indicating that our hypothesis was correct.

The Effects of Nitrogen and Phosphorus Enrichment on Water Samples from Encanto Lake and the Rio Salado River.

The aim is to identify and associate landforms, rock types and soils to the natural environment and its plants and animals and also to investigate the history of the local environment, comprising human impacts over the last 50 years. The impact of human alterations to the environment includes increased soil erosion and changes in river flows.

Exercise Lab 1. How much does temperature vary in large and small aquatic environments? Lab 2. What determines the water clarity of lakes, rivers and oceans? Lab 3. Where does the phosphorus go? Lab 4. How does human activity in watersheds affect the quality of lakes and rivers? Lab 5. Are the Great Lakes being influenced by the global greenhouse effect? Lab 6. How is the flow of the Red Cedar River influenced by the weather? Lab 7. What is the relationship between flow and turbidity in the Red Cedar River? Page 2 4 6 8 12 15 18

Phosphorus, “...the primary algae-feeding nutrient in Lake Erie, and contributed to the largest algae bloom in history last year” (McCarty, para. 3), is a key factor in how

While in many ways the two lakes share similar attributes, they can also be observed as their own entities. Each lake containing characteristics that make them preferred for some species types. In addition, the region shares some environmental concerns. Those concerns pertaining to invasive species as well as poor water quality. Both of which impact the physical characteristics, and natural life of the organisms that make up the many different habitats the region

How does the LSC potentially influence the phosphorus cycle of Cayuga Lake? Include in your explanation relevant details of the LSC system and the ecological properties of Cayuga Lake.: Based on some assumptions, the LSC contributes 2.4% of all of the phosphorous that is in the southern lake basin. The monthly max LSC contribution to phosphorous loading is around 6.4% during August. There is no measurable oxygen depletion in the lake and there is no measurable increases in algal growth. Consequently, implementation of LSC will not cause or contribute to growth of these nuisance organisms.

We also compare the River Leith to the Bradshaw model and see if the River Leith does follow the model of a typical river. This is done by measuring 20 sites in 3 river courses, the upper course, the middle course, and the lower course, we then compare these results to the Bradshaw Model and see if the River Leith has the typical properties of a river.

Water is an important resource and weather agent in our world, and the Great Lakes Region has an intimate relationship with water. The region was shaped by glaciers long ago and continues to be shaped by flowing surface water today. Groundwater is very pure in the area, which allows for plants, animals, and humans to thrive there. Migration into the area can be related to the groundwater found there. Human use of the water results in man-made structures, water flow alteration, and changes in water quality. Water is very influential in the Great Lakes Region.

The location chosen for study is The River Stinchar and its tributaries which are located in South Ayrshire and flow south west from the Galloway Forest Park and were chosen due to a previous visit to the area. The location can be seen in figure 1.

The Banks Group comprises of Hettangian to Sinemurian sediments up to 800 ft thick and forms the lower of the two reservoir sections within the Strathspey Field. The Nansen and Statfjord Formations are sub-divisions within the unit (Knox and Cordey, 1993). The Stratfjord Formation shows a significant increase in net to gross from the conformably underlying Cormorant Formation. The formation consists of medium to coarse grained, fluvial channel sandstones interbedded with mud prone overbank and palaeosol deposits. The Nansen Formation overlies the Statfjord Formation and is composed of clean, tabular sandstone deposited under shallow marine conditions (Maxwell et al., 2003).

The upper catchment of the south arm is surrounded by fragments of banksia heath lands, populated by dwarf White Banksia (Banksia integrifolia), with

Lake Gormire, the only natural lake of any real size amidst the moors, is a relic of the last Ice Age. The lake formed some 10,000 years ago when a glacial overflow channel became blocked by a landslide of mud and rubble. It covers an area of about 6 acres (10.6ha) and is about 27 feet (8m) deep at the centre. The lake has no visible feeder streams and therefore it must rely on under­water springs and rain to replenish its volume. Although the lake was once thought to have no outlet, there is a small recess on the eastern shore where the lake overflows and escapes through the rocks. According to one of Gormire’s many legends, a duck once penetrated this dark gully, emerging again to the light of day near Kirby­moorside, more than

The survey was carried out at Keg Lake on Curtin University grounds as shown in the map below:

Rivers, reservoirs, lochs and wetlands make a large contribution to the character of the Scottish landscape.
