Can a body of water become anoxic water?

Not completely, but enough to kill any plants or animals that live in it.

Can a methane bubble sink a ship or a plane?

A methane bubble itself is unlikely to sink a ship or a plane directly. In water, large methane bubbles can rise quickly and potentially disrupt the buoyancy of a vessel, but they wouldn't have enough mass to cause sinking. In the air, methane is lighter than air and would dissipate quickly, posing little threat to aircraft. However, if a significant release of methane were to ignite or cause an explosion, that could pose serious risks to both ships and planes.

What change led to the growth and expansion of modern oceanography in the 20th century?

The growth and expansion of modern oceanography in the 20th century was significantly driven by advancements in technology, such as the development of research vessels, sonar mapping, and submersible vehicles. These innovations allowed scientists to explore and study the ocean's depths more effectively and accurately than ever before. Additionally, the increasing recognition of the ocean's role in global climate systems and the need for sustainable resource management spurred funding and interest in oceanographic research. As a result, interdisciplinary collaborations emerged, integrating oceanography with fields like meteorology, biology, and geology.

Where is Christmas ridge underwater 120 miles off of Tampa fl?

Christmas Ridge is an underwater geological feature located in the Gulf of Mexico, approximately 120 miles off the coast of Tampa, Florida. It is part of the larger continental shelf and serves as a habitat for various marine life. The ridge is characterized by its distinct topography, which includes elevated areas and valleys, making it an interesting site for fishing and exploration.

What is the ocean current that flows past Perth?

The ocean current that flows past Perth is primarily the Leeuwin Current. This warm, southward-flowing current originates from the tropical waters of the Indian Ocean and moves along the western coast of Australia. It influences the local climate and marine ecosystem, bringing warmer water and nutrients that support diverse marine life.

How do you make the Temple of the Ocean King quake?

To make the Temple of the Ocean King quake in "The Legend of Zelda: Phantom Hourglass," you need to use the Phantom Hourglass itself. By activating the hourglass, you can manipulate time and the temple's environment. Additionally, you may need to defeat specific enemies and solve puzzles to progress, ultimately leading to the quaking effect as part of the game's mechanics.

What is volcanic activity of the ocean floor can cause giant tidal waves called?

Volcanic activity on the ocean floor can cause giant tidal waves known as tsunamis. These waves are typically triggered by underwater volcanic eruptions or the collapse of volcanic islands, which displace large volumes of water. When the energy from the eruption or collapse is released, it generates powerful waves that can travel across oceans at high speeds, leading to significant coastal impact upon reaching land.

Why many harbors port in Atlantic Ocean?

Many harbors are located along the Atlantic Ocean due to its historical significance as a major trade route, facilitating commerce between Europe, North America, and beyond. The ocean's vastness provides deep waters suitable for large vessels, making it ideal for shipping and fishing industries. Additionally, the Atlantic's geographic features, such as sheltered bays and natural inlets, enhance the safety and accessibility of these ports. This combination of economic and logistical advantages has led to the establishment of numerous bustling harbors along its shores.

What locations contains the most water in Earths hydrosphere aside from the oceans?

Aside from the oceans, the largest reservoirs of water in Earth's hydrosphere are found in glaciers and ice caps, primarily in Antarctica and Greenland. Additionally, significant amounts of freshwater are stored in underground aquifers, which are critical for drinking water and irrigation. Lakes, rivers, and wetlands also contribute to the hydrosphere, with the largest freshwater lakes being the Great Lakes in North America and Lake Baikal in Russia.

Which rivers on your map empty into a the Atlantic Ocean?

To determine which rivers empty into the Atlantic Ocean, one would typically look for major rivers such as the Amazon, the Mississippi, the Congo, and the Saint Lawrence. These rivers flow into the Atlantic, contributing to its vast watershed. Additional smaller rivers along the eastern coast of North America and parts of Western Europe also discharge into the Atlantic. Specific rivers can vary based on the regional map being referenced.

When did Amelia Earhart get an award for flying across the Atlantic Ocean?

That was in 1928 when she flew as the first woman passenger to cross the Atlantic.

What is a force that pushes currents westward across the tropical latitudes latitdues of all thr ee major oceans called?

The force that pushes currents westward across the tropical latitudes of all three major oceans is called the Coriolis force. This force is a result of the Earth's rotation and causes moving objects, such as ocean currents, to veer to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

Why did Allah make ocean water salty?

Galatians 1:8 But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let them be under God’s curse!

Marine Biology: The Ocean is The Office Here?

Marine biology is a branch of the broad field of oceanography - as well as biology - and is the study of marine (oceanic) organisms that includes plants and animals. A marine biologist is a professional who studies one or more (sometimes even dozens) of aquatic species native to various oceans, estuaries, and bays. Usually, marine biologists specialize in specific niches in marine biology such as marine wildlife preservation, microbiology (zooplankton, amoeba, etc.), ichthyology (fish), fishery, marine mammalogy, invertebrate zoology and many more specializations.

Job Description

Despite common belief among younger people, most marine biologists does not typically work with or study only big mammals such as whales and dolphins; however, a marine zoologist may choose to concentrate on mammals. Other marine biologists usually study different groups of animals according to their scientific classification. A few examples of what real-life marine biologists do include:

&Analyzes populations and helps preserve protected and/or endangered marine species

&Studies microorganisms - such as plankton, phytoplankton, and amoeba - and interprets their importance to the marine ecosystem

&Work at various aquariums as educators and/or scientists

&Work at various research institutions and locations both in the lab and in the field - especially those affiliated with the biology departments of many universities

Students who want to pursue a career in marine biology should realize that most job titles, while directly related to marine biology, are not specifically labeled marine biologist. Zoologists, mammalogists, biological oceanographers, and marine conservationists are, hence, more representative of terms for real-life marine biologists.

Education and Salary for Marine Biologists

Most marine biologists obtain a bachelor's degree in biology, zoology, oceanography, fishery, or biological oceanography. Consequently, most of them go further to acquire a master's degree or PhD in one or more of the formerly mentioned subjects (plus others) - depending on the university or accredited learning institution.

Candidates for this field should have a fond passion for the ocean and preserving life within it - especially because many of the jobs within the broad field of marine biology do not pay that well in relation to the amount of education that's needed. For example, a newly-hired marine biologists researcher or professor/educator can expect to earn around $40,000 to $45,000. Those with highly advanced degrees, a PhD or doctorate to be specific, can look forward to salaries of up to about $80,000 per year.

While those figures are not very competitive with other comparable jobs' salaries with similar levels of education, there are many perks. Many MB's get to travel the world and to exotic places to conduct research. Many, if not most, marine biologists are licensed scuba divers. Furthermore, marine biologists love their work much more than people in other careers because they know that they are making a significant contribution to the planet.

Does the density of water change as a function of dissolved salt?

Yes, the density of water increases as salt is dissolved in it. This is because the salt adds mass to the water without significantly changing its volume. The increase in density allows objects to float more easily in saltwater compared to freshwater.
