This was an exciting result for the scientist Dabiri because it meant that if this was truly done on a larger scale every day in the ocean, these tiny shrimp could be another factor in regulating the temperature and nutrient cycling of the oceans. This idea would also
Currents are the ocean’s constant flow of water that is pushed on by either the wind or from tides that are caused by the moon’s gravitational field. Currents can occur along coasts, and sometimes only affect small areas. A longshore current is caused when waves strike the beach at an angle. The front part of the wave hits the shallow water first and slow down. Rip currents are a dangerous effect of longshore currents.
Ambereen Alvi Geo 102 Extra Credit Ocean Currents Ocean Currents: How They are Made and Work What is an Ocean Current? And what does it have to do with you? Ocean curents are the continuos, direct movement of ocean water generated by forces upon the ocean. This can depend on things we can experience directly like wind, temperature, and water density, and also those things a little less obvious like the rotation and mass of our earth. Together these things work to create ocean currents that help in the overall vitality on our earth dynamic surface.
How Are Water Quality Standards Determined? No name EVS 1001-51 June 25, 2012 Professor Thomas Rich How Are Water Quality Standards Determined? The earth is made up of mostly water even though we may not notice or see it, but water plays a very important part of life even though we may not think of it. Just our day to day activity everybody needs water at least seventy five percent of the day whether it’s to drink, cook, or wash its needed. Often times people use the water people never stop to think or wonder where are we receiving the water or the quality of the water that are used in the food we eat.
Fish needed to find out in his experiment, how to measure the forces dolphins produced during swimming. With the collaboration of Timothy Wei, who studies Olympic swimmers and Terrie Williams, a marine biologist; worked together on a new method to obtain the data they needed without harming the dolphins. They created an experiment with a bubble curtain and laser; and finally they can measure the force. The results proved that dolphin’s tails or fluke, can produce the enough force to swim fast when they swim in circle. Their tails are so flexible and can maintain the speed.
The voyage that Thomson did it had birthed oceanography. All this data that Thomson collected was served as a basis for the study of Marine Biology for many years. A British explorer, Edward Forbes, said that marine life doesn’t exist below 550 m or 1,800 feet in sea. The HMS Challenger was well built and stocked with a lot of supplies. It had laboratories on the ship and microscopes, chemistry supplies, trawls, and dredges etc.
(Does not aim to stop the coastal erosion completely) Examples of soft engineering: 1) Beach replenishment 2) Beach drainage HARD ENGINEERING Sea walls A seawall is a form of coastal defence constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation and leisure activities from the action of tides and waves. As a seawall is a static feature it will conflict with the dynamic nature of the coast and impede the exchange of sediment between land and sea. Advantages * Protects the base of cliffs against erosion. * Can prevent coastal flooding in some areas.
They are a source of food and medicine, and they protect the coast from wave erosion. Profile of coral reef with typical reef "zones" Corals are marine animals related to jellyfish and anemones. Both colonial and solitary corals catch plankton (microscopic plants and animals) and other suspended food particles with arm-like tentacles, which feed a centrally located mouth. Most hard corals also host symbiotic algae, a long-standing and successful partnership. These algae provide them with an additional food source through photosynthesis.
They are coral mining, climate, diseases, tourism, blast fishing, farm runoff, sewage, oil and industrial pollution. Vacationers feel privileged to be able to deep sea dive and get a firsthand look at the incredible biodiversity that the reefs provide. They are unaware of the fact that just by touching the fragile coral, as shown in the photograph; they are damaging its delicate tissue. The coral reefs provide homes for many varieties of plant and animals. Many different kinds of fish live in the reefs as their haven for feeding, reproduction, and safety from predators.
Fish are very sensitive to chlorine and other impurities in tap water. Allowing the tap water to sit out for a few days will rid it of any impurities and you will then be able to fill up your aquarium. The items discussed are very easy to acquire and even afford, but can make the difference in life and death for your fish.
