Oceanography

Earth doesn't have one continuous, constant atmospheric pressure, it varies both spatialy and temporally. Assuming you're talking about the atmospheric pressure at the Earth's surface, the "standard" atmospheric pressure is 1000 millibars (mb), however pressures can range anywhere from ~875 mb (in intense low pressure areas such as the center of tropical cyclones) to ~1080mb.

An incoming tide refers to the period when the water level is rising towards the shore due to gravitational forces from the moon. It is typically associated with higher water levels and can create strong currents in coastal areas.

Deep ocean currents are created by many elements. The first, is called the

Thermohaline circulation, Thermo meaning hot and cold water interacting and haline meaning the amount of salt water verses fresh water, that changes places when ice melts and refreezes in the ocean. This circulation of cold rich salt water and warm surface water starts at the equator, where the water is warmed by the tropical sun and pushed ever north ward by cold dense water that flows from the poles.

The second element that creates deep ocean currents is called the Coriolis effect, in physics this element is easiest explain by placing a rolling ball on a turning table. If the table where to remain stationary the ball when rolled would effectively roll straight and not deviate from its straight line. Where as with this effect if the ball where to be rolled while the table where in motion the ball would deviate from the straight line and roll off in the direction that the table is rolling in. As currents come from the poles they deviate from their straight path and fall along the continents. Thus creating deep ocean currents .

Marine mammals, such as dolphins and whales, can suffer from intentional human contact. Examples of this include disturbances from boat traffic, noise pollution, and feeding these animals, which can disrupt their natural behaviors and affect their well-being.

The solubility of oxygen in water decreases as water temperature increases, making it harder for aquatic animals to obtain enough oxygen to support their metabolism in deep, warmer waters where oxygen concentrations may be naturally lower. This can create oxygen-depleted zones that limit the distribution and survival of marine organisms.

The periodic rise and fall of ocean water is known as the tidal cycle. It is caused by gravitational forces exerted by the moon and the sun on the Earth's ocean water, resulting in bulges of water that move around the planet as the Earth rotates. Tides typically occur twice a day, causing high tide and low tide.

Waves erode the coast through hydraulic action (the force of the water itself), abrasion (rock fragments carried by the waves), and corrosion (dissolving rocks like limestone). Over time, these processes wear away the coastline, shaping it through the removal of sediments and rocks.

True. The up-down type of wave is called a "transverse wave". Light, for example, is this kind of wave. Sound, however, is a different kind of wave. It is the back-forth type, called "longitudinal", or "compression" waves.

Hydrogenous sediments form when minerals precipitate directly from seawater as a result of chemical reactions or biological processes. For example, manganese nodules and phosphorite deposits are examples of hydrogenous sediments that form in this way in the deep sea. These sediments accumulate slowly over time on the ocean floor.

Icebergs are less dense than water because they are made up of frozen freshwater, while water is denser with salt and other impurities. This lower density allows icebergs to float on the surface of the water. However, about 90% of the iceberg's mass is beneath the surface, giving them stability and making them prone to flipping.

In the homogeneous region of the ocean, there is a lack of layering due to thorough mixing of water masses. This occurs in areas where strong currents or turbulence disrupt the formation of distinct layers based on temperature and salinity.

The student was drawn to study oceanography because of their fascination with the mysteries of the deep sea, marine life, and environmental conservation efforts related to the oceans. They may also have a passion for exploring and understanding the complex systems that govern our oceans.

When salt water evaporates, the water molecules rise as vapor, leaving the salt molecules behind. This vapor then cools and condenses to form clouds, eventually leading to precipitation as rain. The rainwater is then collected as fresh water.

Geostrophic flow works in opposition to Ekman transport in a gyre. Geostrophic flow is the balance between the pressure gradient force and the Coriolis force, causing water to move at an angle to the wind direction. This balances the net transport of water caused by Ekman transport.

Yes, the Gulf Stream transports warm water from the tropics toward the North Atlantic, away from the equator. The Benguela Current located off the southwest coast of Africa transports some of this water back towards the equator, creating a cyclical flow pattern in the ocean.

The average depth of the Atlantic ocean is 10,955 feet. The deepest part of the ocean is about 28,232 feet deep in an area called the Milwaukee Deep.

There is no specific data on the number of people who die each year due to high tides. High tides can lead to drowning or flooding-related accidents, but the exact number of deaths would vary based on factors such as location, warning systems, and emergency preparedness measures in place.

Dolphins and supposedly apes and monkeys are the most intelligent mammals on our planet. And I guess I should put that we are mammals too. Which makes us another mammal that is the most intelligent (well, some of us). :0)

the spin of the earth forces the water centrifugal force) to the equator in a bulge.. although it raises sea heights it does not make it more dense ...water cannot be compressed and made more dense

Energy from waves can erode shorelines by wearing away the coast and causing cliffs to collapse. It can also shape the coastline by depositing sediments in certain areas, building up beaches or barrier islands. Additionally, wave energy can affect coastal ecosystems by altering habitats and influencing the distribution of marine life.

The surface zone is warmer than the thermocline because it is directly exposed to sunlight, which heats up the top layer of the water. In contrast, the thermocline is a transition layer where temperature decreases rapidly with depth, creating a barrier to heat transfer from the surface to deeper waters.

Thermocline circulation refers to the vertical movement of water in the ocean based on differences in temperature. Warmer, less dense water sits on top of cooler, denser water, creating a boundary called the thermocline. This circulation plays a critical role in distributing heat and nutrients throughout the ocean.

The Virgin Islands experience both high and low tides due to the influence of the moon's gravitational pull. Tides in the region are typically moderate, with variations in amplitude depending on the specific location within the Virgin Islands.
