Discovering Ancient Climates in Ocean & Ice | Rob Dunbar | Summary What Dunbar discussed in this lecture was sea level rise, ocean warming and ocean acidification. He also explained the environmental conditions revealed by marine sediments and the negative effects that carbon dioxide has on the ocean. It was easier for me to understand how sediment works and how he went upon researching it. When he talked about carbon dioxide and the negative effects it has on the ocean I was shocked. I did

more funding or any funding at all? We live in a time of every organization within the government, to include the military, are dealing with budget cuts. The NOAA’s website states “from the surface of the sun to the depths of the ocean floor” (Sullivan, 2014). The oceans cover 70% of the earth’s surface. The magnitude of the area of responsibility of the NOAA is astounding. The people of the United States utilize studies and services of the NOAA on a daily basis and many Americans don’t even know

affect our ecosystem both in the ecological way as well as chemical? Beck’s research is important because if oyster reefs go extinct the metal toxins in the ocean will rise due to the fact that there will be no oysters to filter the water. Sophie Buisson, life scientist, addresses the questioning of whether higher amounts of toxins in the ocean and warmer water temperatures were the main factors of increased oyster mortality over the past decade. In the 2008 study "Level of Contamination and Impact

of this: * Biomagnification describes situations where toxins (such as heavy metals) may pass through trophic levels, becoming exponentially more concentrated in the process. * Carbon dioxide emissions cause ocean acidification, the ongoing decrease in the pH of the Earth's oceans as CO2becomes dissolved. * The emission of greenhouse gases leads to global warming which affects ecosystems in many ways. * Invasive species can out compete native species and reduce biodiversity. Invasive plants

revolution, that number has risen to over 400 parts per million. Secondly, despite what skeptics may say, the ocean levels are rising. Since 1993, the oceans have risen an average of 3.19 millimeters per year. This is primarily due to thermal expansion and melting surface ice. And my third evidence, extreme weather is becoming worse as the temperatures of the oceans rise. Although a warmer ocean does make

Ocean Exploration Our oceans are a very mysterious world that still remarkably unexplored. However, there is life and astounding variety of creatures that will blow your mind. You can explore the ocean until a certain point, but you can’t explore the deep ocean on your own. Scientists now have a variety of sophisticated technologies to explore this vast frontier. What they’re finding will amaze you. According to source #1 Oceans: Earth’s Final Frontier, there is a lot going on in the deep water

“Climate change and global warming talk about to an increase of usual global temperature. Natural disasters and human actions are believe to be the main reasons for the happening of average global temperatures increase. This is happen because of increase in ‘greenhouse’ gases such as Carbon Dioxide. A warming planet therefore leads to a revolution in climate which can affect weather in different behaviours.” Climate change mostly happens by the natural cycle of earth however as of now human exercises

How does littering affect marine wildlife? Littering has become a much bigger problem in the world than it used to be. It has begun to even affect the wildlife around us all, especially marine wildlife. The litter has been getting into the water from many different ways, it can be flushed down the toilet, left on the road and washed into drains and waterways when it rains, and the most common way would be dropped directly into the water by boaters. Plastics have the most affects on the marine wildlife

Finding Nemo??? I remember the time that I found him. He was still in the egg and my wife was no where to be found. Earlier in the day we swam down to the plethora of kids we were going to have and were deciding on what to name them. Coral my wife wanted at least one of the kids name to be Nemo. I preferred to keep it simple and wanted to name half of the kids Marlin Jr. and the other half Coral Jr. after both of our names. I really didn’t care at the time and in the back of my mind I liked
