Sonar Essay

Oceanography also called oceanology or marine science, is the branch of Earth science that studies the ocean. It covers a wide range of topics, including marine organisms and ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers blend to further knowledge of the world ocean and understanding of processes within it: biology, chemistry, geology, meteorology, and physics as well as geography.

On March 21st, our class went to the Monterey Bay Aquarium. The purpose of this trip was not only to explore Earth’s natural habitat’s, but it was also to gather information on our upcoming project and to gather information on how the community of St.Mary, affects the Monterey Bay Aquarium. The answer that we found out is one based off of what we eat. The Monterey Bay Aquarium released an app where it showed which type of seafood were lower in numbers than others. So, if plankton were very low in numbers, it is advised that we not fish for them or not eat as much of it. This shows based just off of what we eat, we can affect the numbers of in the ocean. Also, those plastic bags we buy at Target and Walmart, that we drop outside, drifts itself to the streams, which flow to rivers, which go to oceans, they are floating there, not doing much harm, until sea turtle comes by starts eating it, but gets tangled and choked in it, dies.

Astonishingly, Did you know that we have better maps of the moon than we do of the ocean? (#7) It’s true! Scientists are working to make drones to explore the deep sea. Ocean Exploration is a developing science that incorporates the use of marine biology and drone technology. Ocean Exploration technology will be an overall benefit to society because 1. exploring the ocean is easier than before and 2. ocean exploration can help with monitoring the deep sea.

Presented in an informal style of writing, “What Is Ocean Exploration and Why Is It Important?” inform its readers about the importance of researching and discovering the unknown ocean. It explains how much work is needed for the documentation of the ocean in varies areas, at the same time it addresses that scientist will be able to better understand the unknown oceans. For example, the time needed to obtain and study the result, as well as answer how the change in atmosphere will cause the ocean to react and affect life. The information obtain will also provide the baseline for scientist, researcher and government agencies to make important and dangerous decisions for the future. Sometime during research amazing things happen and new resources may be revealed. Besides informing about the ocean researching, the article also has a background idea as it is trying to encourage and get its readers interested into joining the field of ocean researching by emphasizing the role the ocean plays and how it will help ensure that ocean resources are well managed for future generations to enjoy.

In this episode of the BBC documentary series, “The Blue Planet: Open Ocean,” we were able to explore the abundance and complications of the open ocean, the pelagic zone. Over 60% of our planet is covered by the ocean, yet the deep sea is largely still unknown. We know more about the moon than what we know about the deep ocean. The temperature and the level of sunlight decrease as the depth increases. The ocean may appear uniform from the surface, but there is several layers to the ocean. The pelagic zone contains the most area of the open ocean. The zone includes everything except for the coastal waters and the sea floor. However, even within this area, there are variation since some part is lifeless with very little amount of organisms and

Sonar had been invented before World War I, but after 1942 the US Navy Department developed ‘console sonar’ which could plot accurate bearings using an echo ‘ping’. Training of sonar operators was also improved.

Ever since Sea World opened it’s gates in 1959 it has been mistreating aquatic sea life and endangering employees. In the next few months there should be a petition emailed to everyone who is subscribed to any wildlife protection groups encouraging everyone to voice their concern. As of today there are a large number of citizens of the United States and several other countries spreading the word of the awful conduct of Sea World and their mistreatment of endangered wildlife.

In order to determine how the oceans have changed over time and to identify what might have

The only way we can get a full picture of state of our oceans and an idea of how to better manage them is through scientific exploration and research. This scientific work costs money and at the time of the councils recommendations, funding was only half of what they believed to be a sufficient amount to fully study the oceans. Money is a maker or breaker in many aspects of research. Without funds the ability to produce needed data is extremely handicapped. With appropriate funding one of the ways the US Ocean council suggests

The mission is called CORAL and it “...combines aerial surveys using imaging spectrometer technology…with ‘in-water validation’ provided by CSIRO and the University of Queensland” (“NASA begins study of the Great Barrier Reef” 1). A:Dr. Tim Malthus, research leader of CSIRO’s coastal monitoring, modeling, and informatics group, believes that a larger understanding of the reef will help researchers gain a better understanding of how it can be protected (“NASA begins study of the Great Barrier Reef” 2). E: CORAL is unlike any research done ever before because it will study the health of corals in the Torres Strait along with surveying large sections of the reef (“NASA begins study of the Great Barrier Reef” 2). Dr Tim Malthus stated that the Torres Strait is a “complex high tide area that has been historically less studied “ and by researching it, scientists might gain more information about the causes of decline in that area. In order to gain this unstudied data, CORAL will describe coral reef condition and measure three key places of reef health where data is currently limited: composition, primary productivity,

The ocean's surface waters are separated from colder, deeper water by a thermocline. The upwelling of cold waters, along the equator in the eastern half of the pacific basin, can be blocked when sea level is high, resulting in warm events. When sea levels are low the thermocline tends to be shallow, allowing upwelling motions to bring cold water to the surface, resulting in cold conditions. How it's measured is by devices used to track decadal variability and climate patterns which includes thermometers, rain gauges, and stream gauges. Sea surfaces temperature is important in tracking ENSO and other ocean oscillations. This can be measured by the distance

The day to day activities of a Marine Biologist includes conducting species inventories, testing and monitoring sea creatures exposed to pollutants, collecting samples and data-using processes such as coring techniques, visual recording and sampling, analysing these samples in a lab and developing new research theories from them. Marine Biologist preserve specimens and samples of unknown species and diseases and mapping the distribution, ranges or movements of marine population, designing scientific experiments and collating findings, preparing detailed reports for agencies, commercial organisation, communicating the latest advances in marine science to help improve the ways in which we look after our oceans through academic publications, and evaluating the likely environmental impacts of a proposed project or development, including socio-economic,

The National Science Foundation is an independent federal agency created by congress “to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense…" Each year they are given a budget of millions of dollars to fund research in all fields of fundamental science and engineering, excluding medical sciences. One major project the National Science Foundation funds is called Ocean Observatories Initiative (OOI). The OOI is an integrated infrastructure project composed of science-driven platforms and sensor systems that measure physical, chemical, geological and biological properties and processes from the seafloor to the air-sea interface. The Ocean Observatories Initiative was created to better understanding of earth oceans and being able to solve problems such as climate change, ecosystem variability, ocean acidification, and carbon cycling.

The ocean plays a critical role in removing carbon from the atmosphere and providing oxygen. It regulates Earth's climate. The ocean is an increasingly important source of biomedical organisms with enormous potential for fighting disease. These are just a few examples of the importance of the ocean to life on land.

For many years humans have struggled to discover the deepest parts of the ocean and have also struggled with discovering space. We could not go really deep into the ocean, because humans can not withstand the pressure that the ocean produces. But now there is a robot that can reach the ocean floor called “The Benthic Rover”. With that new robot, scientist will be able to record how changes on the surface of the ocean will impact the marine animals below. “What is special about the rover is that we will be able to stay in the deep parts of the ocean for a really long time collecting seasonal changes data” (Engineer Alana Sherman). With Benthic Rover,
