Lab Report On Algal Biomass

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.

In lake sas man has built a dam, but to the elevation of the sampling site the team believes that the dame does not effect the soil. The soil sampling site appears to be in a natural state. No human impact effected the sampling site, the samples collected are relatively accurate to the natural soil state.

The U.S. Environmental Protection Agency (EPA) Region 6 office is the lead agency for this Site and has conducted remedial activities at the site since the 1990’s. The Louisiana Department of Environmental Quality (LDEQ) is the support

How have urbanization processes impacted the geomorphology of the D’Olive Creek Watershed? This project will explore the known environmental impacts of the urbanization process and compare this to the impacts of urbanization in the D’Olive Creek Watershed, with specific emphasis on the temporal geomorphology of the area. The D’Olive Creek Watershed is located in Baldwin County, Alabama and is part of Mobile Bay, which is classified as one of the largest and most ecologically significant estuaries in the United States – it is also a member of the National Estuary Program (Stout et al. 1998, p. xv). There are many anthropogenic factors associated with urban development that could detrimentally impact the local environment: impervious surfaces,

The loss of Louisiana coastal land is one of the most major factors in our environment today. Louisiana has already loss 1,880 square miles of land in the past eight decades. This problem is effecting the state funding to help solve the problem before the state lose more coastal land. Human disturbance has had a massive impact on the balance of wetland growth and decline. (Wilson, 2013). In order to stop this situation the state needs to have a stronger structural protection for the coast line. (Wilson, 2013).

The location of the two different sites selected to be assessed are provided in the map below (figure 1). Site 1 is located at the marina with a major mangrove ecosystem and a surrounding recreational land area that may affect the overall quality of the site. Site 2 is located beside the Gateway Motorway, the Brisbane Entertainment Centre, a nearby airport and a waste disposal yard. Both sites were assessed at high tide which leads to a large range of possibilities in data accuracy. Site 1 is managed all year round whilst site 2 is currently

Soil erosion is proven to be the dominant sediment source within catchments, comprising up to 63% of the sediment flowing into rivers (McKergow, Prosser, Hughes, & Brodie, 2005, pp.200). It is estimated that by the end of the 20th century, agricultural purposes had caused the clearing of more than 50% of the natural vegetation in Queensland (Bowen & Bowen, 2002, pp. 407). In 1999, 90% of all land cleared in Australia was located within Queensland, an estimated 400,000 hectares (Bowen & Bowen, 2002, pp. 407). Cropping, particularly sugarcane, and beef grazing are the main sources of soil erosion, as well as cotton and minor urban development (Brodie et al., 2007). Use of nitrogen fertilization (De’ath & Fabricius, 2010) has also caused a flux of nutrients to make their way to the Great Barrier Reef, causing eutrophication in some areas (Brodie, Wolanski, Lewis, & Bainbridge, 2012, pp. 267). Degradation of land assigned for Pastoral purposes has been the main contemporary source of sediments, owing the impact they have to the sheer amount of cleared land that is designated to beef grazing (Neil, Orpin, Ridd, & Yu, 2002, pp. 733). Unlike agricultural practices which use highly fertilized soils, the exported nutrients from cattle grazing land are from natural, unfertilized soil that results from erosion inland (Brodie et al.,

Within each zone, alterations in physical features of the landscape can blur zonation patterns (Graham & Wilcox, 2000; Stephenson & Stephenson, 1949; 1937; Lipkin, 1971; McQuaid & Branch, 1984). Additionally, between each zone there is a “fringe” zone where species from each zone can persist in small numbers before reaching their range limit (the “supralittoral fringe” and the “infralittoral fringe”) (Stephenson & Stephenson, 1949). Boulders, crevices, and tide pools all create microhabitats within the zones (Graham & Wilcox, 2000; Stephenson & Stephenson, 1949; Lartigue, 2003; Bolton & Anderson, 1990; Underwood, 2000). The presence of these features can alter the effects of abiotic factors such as light availability, salinity, and wave

Secondarily, the EPA compared the sediment data and water samples to ecological risk based screening levels. In this study, the EPA did find some levels to exceed ecological screening levels in both the sediment data and water samples. The action that the

The D’Olive Creek and Fly Creek Watersheds are both connected to Mobile Bay and integral parts of the environmental health of the bay (Figure 1). The network of habitats found in Mobile Bay supports the greatest diversity of species out of all states east of the Mississippi River (Swann and Herder, 2014). Regarding discharge, Mobile Bay is the fourth largest estuary in the U.S. at 1800 m3/s (Ellis et al, 2011). Over the past few decades, Mobile Bay has experienced much environmental stress related to anthropogenic activities (Ellis et al, 2011). This environmental stress has affected many important, natural systems in the area: wetlands, streams, submerged aquatic vegetation (SAV), longleaf pine forests, and maritime forests (Swann and Herder,

As humanity continues to prosper agriculturally, industrially, and in population, companies, as well as local communities, have obsessively used the Ocean to toss their waste without consequences. The formation of dead zones has been intensified by the increase runoff of fertilizers and the burning of fossil fuels. Enhanced primary production causes algae to bloom at a constant rate creating a layer near the surface. This layer acts as a roof to vegetation below resulting in a lack of oxygen which organisms use to live. According to Robert Diaz and Rutger Rosenberg, “Dead zones have now been reported from more than 400 systems, affecting a total area of more than 245,000 square kilometers, and are probably a key stressor on marine ecosystems.” Specifically, the Chesapeake Bay has been polluted to the point where areas have now been uninhabitable to marine life. Although waste disposal is a difficult issue to solve, polluting bodies of water endangers the marine life, environment, and health of organisms.

"All conflict in literature is, in its simplest form, a struggle between good and evil". This quote by anonymous individual could be explained as; all themes and struggles in literature can be lead down to their most basic forms as conflict of good versus evil. Usually in conflicts, there are two sides that fight over one particular aspect. One side is considered good, which are fighting for their morals, while the other side is considered bad and are fighting for the wrong reasons. (Online 5)

The Effects of Human Activity on Coastal Landforms Human activities add another layer of complexity to the natural processes of coastal lands and materials. These activities may have direct or indirect effects on our changing coastlines. They may effect sources of new sediment to the coast and the movement of sediment within the coastal environment. Sediment starvation caused by river and coastal management is one effect of human activities on the coast. For some coastal regions, such as the Pacific coast, a large part of their sediment is supplied by rivers.

Hemingway and the Struggle of Masculinity in WarMen in A Farewell to Arms and For Whom The Bell TollsThe name of Ernest Hemingway has long been associated with the idea of a strong, stubborn man who is very socially inept. In both A Farewell to Arms and For Whom the Bell Tolls, we are introduced to an extremely cold, unfeeling character and we see how they evolve from one type of man into another. Frederic Henry and Robert Jordan are both Americans serving overseas in some conflict, Henry being in World War I and Jordan in the Spanish Civil War between the fascists and communists, and they originally see these conflicts as a way for them to prove their manhood. They soon realize that war is not meant for all people and that it should not

Coastal erosion is known as the natural removal of land and sand caused by changing wave conditions, coastal erosion is also caused by storm events which creates a massive amount of destruction to the beach and can put building and infrastructure in potential danger (SES, 2016). Some of the factors that affect coastal erosion include: strength of waves, weather as well as human activity can all negatively impact the amount of erosion (A. Jackson, 2016). Beaches are an important part of the world’s ecosystem for they provide homes for many species of animals such as: birds, crabs, invertebrates, turtle eggs, etc. Beaches also provide services such as sediment storage and transport, wave dissipation and associated buffering against extreme weather
