2 Literature review 2.1 Mercury in the Arctic marine environments: As there are practically no point sources of industrial Hg close to the Arctic environment, the main source of Hg is from long range atmospheric transport (from lower latitude) particularly from Asia, Europe and North American emissions and other geologic sources (Braune et al., 1991). Despite significant Hg coming to the Arctic through long range atmospheric transport, the riverine (i.e., terrestrial runoff) and costal erosion or

or swim in the ocean. Marine biology encompasses the ones that make the seven seas their home. It is the study and appreciation of marine life and their environments. From the sandy beaches to the ocean depths, from the tropical reefs to the polar ice caps, much of the life on earth thrives in the ocean, which affects us on land, too. It is understandable why we, as scientists, explorers, and curious kids would want to know more about what lives in the open sea. But marine biology is not just simply

Introduction: The conditions of the marine environment place special demands on the design and use of a camera (ERT Task Sheet, 2015). An average above surface camera cannot simply be made waterproof using a camera housing in order to operate effectively underwater. There are special demands created by various aspects of the marine environment for example, the lens must be designed specifically to recorrect the distortion created by refraction and strobes must be placed away from the camera to avoid

warehouse in soil and water of radioactive pollutants from the atmosphere fallen occurs. In animals and plants that draw their nourishment from the soil and water bodies such focus, transmitting them to their predators dangerous proportions. In the marine environment it is clearly seen this phenomenon. Algae often come to have a radioactivity specifies thousand times higher than the surrounding water, and plankton concentration factor that can become of 5000. aquatic animals that feed on such organisms can

The main impact that the earth is having on the marine environment is climate change. Increasing the oceans temperature by 0.7 degrees Celsius. What is the Impact of Coral Bleaching? Coral bleaching is one of the visual effect of climate change. Caused by the stress put on the coral because of the temperature of the water becoming warmer. This major effect of climate change could lead to the death of the Coral. This has been especially noticed on the Great Barrier Reef. Only recently the earth

demands for living marine organisms, tension between nations for resources, and the increasing push for seabed mineral extraction, UNCLOS was created (United Nations 2013). The primary purpose of UNCLOS is to support the efficient use of marine resources, the conservation of living resources, and the protection/preservation of the marine environment (Wang 2004). One of the main benefits of UNCLOS is that it increases the ability for coastal nations to be able to create their own marine protected areas

pressure on the marine environment and its resources due to seeking out a livelihood, it is also documented that a considerable percentage of the economy comes from the activities, occupations, and livelihood that really either directly or indirectly on marine resources and several other factors that are present there(Small, Gornitz & Cohen 2000). As a result of this, issues arise from conflicting uses of marine resources either through man’s interaction with the marine environment causing pollution

“Why should the leaders of chemical businesses be held responsible for polluting the marine environment with a few grams of effluent, which is sublethal to marine species, while celebrity chefs are turning out endangered fish at several dozen tables a night without enduring a syllable of criticism” (Charles Clover, 2004). Clover’s stance on overfishing may seem over dramatic, but Clover’s statement is correct in pointing out that the real danger to the ocean’s wildlife is overfishing. Overfishing

Marcus Sarvis Mrs.Ashley Rutherford English IV 12 October 2017 The Impacts of Marine Pollution in Society Throughout history humans have always neglected the ocean and polluted the ocean. Pollution has been around even since the Roman times. Marine pollution today has gotten worse due to the fact that society is ignoring the issue and still making over 220 million tons of plastic that are produced each year. There are now close to 500 dead zones covering the ocean globally That is equivalent to
