Remediation: The mudboils in Tully Valley are caused by artesian pressure. To reduce mudboil sediment discharges from the mudboil depression area to Onondaga Creek, remedial measures were implemented. This includes installing depressurizing wells along Onondaga Creek and around the mudboil depression area to decrease the artesian pressure. Since the majority of mudboils in Tully Valley are located near the Onondaga Creek mudboil passageway and mudboil tributary diversion channel, the…

Eutrophication is a natural occurrence over the past centuries as bodies of water age and contains sediment (Carpenter 1981). However, due to human activities, the rate of eutrophication has increased and now plays a big role in fish kills. This happens when inordinate amount of fertilizers flow down the rivers and streams and into the sea, which in turn encourages algae and most, if not all, aquatic plants to overgrow. Fishes will then suffocate due to lack of oxygen and sunlight excessively…

Uniformitarianism also date the Earth around 4.6 billion years old from the way sediments and layers of soil sediments have been layered. From the use of radioactive dating and the decay of daughter isotopes. Uniformitarianism rejects the scripture of God by the belief in the Big Bang Theory. Catastrophism is events quickly and violently change the face of the Earth. Noah flood changed the face of the Earth burring sediments and fossils. Volcano eruption and violent…

precious marine ecosystems, has been deteriorating due to poor water quality (Kroon et al., 2016). One of the main reasons for this substantial decline in water quality over recent decades is agricultural runoff of nitrogen, pesticides/ herbicides and sediment (Figure 1). In fact, the water quality is most affected in the inshore areas in the southern and central regions near the most intensive agriculture. The impacts are biophysical in their effects on the marine animal and plants of the Reef.…

what we now know as Southern Louisiana. The Mississippi River creates land by depositing sediment into the Gulf of Mexico and whenever it floods, sediment would be left behind which builds up land over time. However, although it takes a very long time to create the land of Louisiana, it can take as little as 45 minutes to lose land. One of the things that destroys land are levees. The levees limit the sediment deposition in the Gulf of Mexico which means not as much land can grow and and land…

of, Greywacke. Figure 1: The Rock Cycle According to figure 1, greywacke is formed deep under the sea. The sediments, known as sand, are then mixed…

It was apparent that upland and upstream industries were a contributor of pollution affecting the area. With the waterway and sediment severely contaminated it was clear that a major cleanup needed to be organized. In 1983, Commencement Bay and the Thea Foss Waterway was declared a “Superfund” site by the Environmental Protection Agency (EPA) under the newly passed Comprehensive…

The redear sunfish primarily feed on mollusks, found near the sediment, and has “shell crackers” or grinding teeth in back of the pharynx that are used to crush snails (Tomelleri and Eberle 1990). In Florida, they are also known to feed on scuds, prawns, and mayfly, dragon fly and midge larvae. When redear sunfish find snails on the bottom, they are known to take a vertical position and dive into the sediment head first (Wilber 1969). Largemouth bass are higher up in the food chain…

bones had been properly examined, but the sediments where they were found had only been given a little bit of attention. The geological similarities of the sediment where the Aitape Skull found and the sediment in 1998 tsunami has led the team to conclude that the population in the area has been hit by inundations over past thousand of years. Oldest Tsunami Victim In The World Researchers analyzed the geochemical composition and grain size of the sediment to futher understand the tsunami…

Conclusively, our research cruise information turns out to fall in general terms. However, there is factors that effect the results. One factor that influences the data results is El Nino. What is El Nino? El Nino is "A southward-flowing, nutrient-poor current of flowing, nutrient-poor current of warm water off the coast of western South America, caused by a breakdown of trade-wind circulation."(Oceanography: An Invitation). Specifically, El Nino influences seawater temperature, density, and…
