Oceanography Response

I examine how rising or falling tide can affect the water level of Corte Madera Salt Marsh in this report. The data is from Wednesday (June 19th) and Thursday (June 20th). My hypothesis is that tide and water level have positive relationship. From the result, I learn that the water level and tide have positive relationship. However, when tide changes its direction, the water level is likely to stay or little change.

For many years now, scientists have believed that our climate is changing. This climate change has caused water currents up north, near Antarctica to shift leading to warm waters taking the place of the usual cold arctic waters. Warm water melts the glaciers and causes the top of the glaciers to float off into the sea, allowing the warm water to melt even more glaciers. The extra glacier melting into our sea has caused the sea levels to raise and the

The off-shore marine environment changes intensively with the change in the ocean depth. There are three distinctive zones that can be classified along the depth which is the Epipelagic which extends from the sea surface to a depth of 200 meters, the mesopelagic which extends from a depth of 200 meters to a depth of a 1000 meters and then the Deep sea which extends from a depth of a 1000 meters to the sea floor (Castro & Huber, 2010). The Deep sea can then be divided into a further three zones (Figure 01) Bathypelagic which extends from a depth of a 1000 meters to 4000 meters, Abyssopelagic which extends from a depth of 4000 meters to 6000 meters and then the Hadopelagic which extends which extends from a depth of 6000 meters to the sea floor (Castro & Huber, 2010).

I chose an article in the CLIMATE MONITORING section. "To Study Earth’s Climate, Look to the Ocean" by Christopher Sarro on October 3, 2017

Critically evaluate the extent to which global warming may impact the functioning of the deep ocean thermohaline circulation.

When surface ocean currents and deep ocean currents bound together as one, thermohaline circulation patterns are formed. These primary currents in Earth's oceans (Pacific, Indian, Atlantic, southern oceans) are bonded together. Thermohaline circulation, as it turns out, plays a major role in Earth's climate and can drastically change it. Providing heat to the north and south polar regions, it also significantly influences the rate at which ice forms near the south and north poles. In this experiment, a change in temperature is brought upon a model of thermohaline circulation patterns to test the effects global warming will have on these ocean currents. Although

The abnormalities of the vast open ocean were first recorded in 1950 by Edward Jones in Miami’s daily newspaper. However, the mystery

I would have to agree with the writers of this article in so many ways. The writer says that the ocean has absorbed tons of carbon dioxide from the earth’s atmosphere causing ocean acidification. The declining of plankton is causing marine

Despite having some of the hottest weather we have ever had on Earth, one place in particular is having the coldest weather on Earth. Scientist are calling it the Atlantic Blob. The Atlantic Blob is a large area in the North Atlantic which is some locations is record cold. Over the past few years there has been a cooling of the Atlantic and a warming of the Pacific. There is also a Pacific blob which is a spot which gets really warm and has an above average season for hurricanes and typhoons. The Atlantic Blob is found by Greenland which is basically a big sheet of ice. 99% of Earth’s freshwater is found in Greenland and Antarctica and scientists believe this melting ice is causing this dip in temperatures. The ice melting in Greenland is affecting

The article that I read was titled Why the ocean has absorbed more carbon over the past decade, by the University of California - Santa Barbara, written on February 8, 2017. The article first began by stating that less carbon dioxide is entering Earth’s atmosphere - it is being absorbed into the oceans - the reason why is not known, but “a slowdown of the ocean's overturning circulation” (sciencedaily.com) is likely to be the cause. The article supports the claim by stating that the discoveries are in the reputable Nature journal. Next, the article quoted UC Santa Barbara geographer Timothy DeVries stating that the circulation slowdown is thought to be a result of human activity from heating and freshening the ocean’s surface which causes melted

In November of 1978, NASA used satellites to track climate change. Then in 2013, Claire Parkinson did a study about the change in the quantity of ice. She finds in her studies that the ice has gone away dramatically at a steady rate. The fresh water inside these capes are melting and in turn the ocean levels are rising. Sea ice has be disappearing in all parts of the Artic. Even though ice has been returning in the Antarctic it will not be enough to make up for all of the ice dissipating. Annually the heat from the greenhouse effect has made the ice caps lose an average of 13,500 square miles since 1979. All of that water is being put back into the ocean therefore the tides are becoming bigger and

In 1875, the ocean trenches was discovered by the HMS Challenger. They used sounding equipment during the global circumnavigation. Ocean trenches are these deep depressions that are the deepest parts of the ocean. These may be the deepest parts of the ocean but they only represent 1 percent or maybe even less of the entire area. The steep walls and the massive submarine slopes make up something called the hadal zone, which is a filled with a diverse number of species. Some of these species today are still new or unknown to science. The ocean trenches are formed due to subductions, which is a geophysical development where two or more of the Earth’s tectonic plates join and the older and denser the plates are, they are then pushed under the lighter plate and deep into the mantle. This will cause the ocean floor to bend and form a steep depression.

The recent decrease in the heating percentage of the Northern Hemisphere could be a consequence of internal variability of the Atlantic Multidecadal Oscillation -- a natural phenomenon associated with ocean surface temperatures, according to Penn State investigators.
