Have you ever thought about how ocean acidification affects organisms that live in the ocean‚ or even what ocean acidification is? First off‚ ocean acidification is a term used to describe significant changes to the chemistry of the ocean. This happens when carbon dioxide is absorbed by the ocean and reacts with seawater to produce acid. Ocean acidification affects many organisms’ homes and shelters. It also destroys many reef ecosystems. Ocean acidification is a bad thing. It’s bad because it

MSC 160 Oceanography Chapter 2 Review Plate Tectonics Study Guide 1. What is the theory of continental drift? 2. Who proposed the theory? When? 3. What scientific data was used to support the theory of continental drift? Identify and explain at least four pieces of evidence. 4. What were the problems with the original theory of continental drift? 5. How does the presence of ocean ridges and trenches support the theory that the continents move?

(Ch. 12‚ Section “How Are Marine Organisms Classified?”) Plankton Plankton is a organism that float. Why is a copepod‚ which can swim and propel itself through the water‚ classified as plankton? (Ch. 12‚ Section “Plankton”) Because of its small size‚ it cannot swim very far or fast so its location

The Neritic zone is also called coastal waters‚ the coastal ocean‚ and the sublittoral zone. It is the part of the ocean extending from the low tide mark to the edge of the continental shelf. It is considered a shallow depth‚ extending to about 200 meters. The Neritic zone has decently well oxygenated water‚ low water pressure‚ and fairly stable temperature and salinity levels. This is the location of most of the sea life in the ocean. Salinity is the level of salt in the water. The Neritic zone

the concept of low nutrients‚ low salinity and high water clarity. The Leeuwin Current originates from tropical regions‚ making it relatively warm in addition to the distinctive lack of large-scale upwelling (http://www.per.marine.csiro.au/public/oceanography/regional/currents.html). Upwelling is the process by which subsurface waters flow upward and replace the water moving away (Skinner‚ et al‚ 1999). This process and other factors that cause the Leeuwin Current and its distinctive attributes will

Oceanic circulations ●Ocean currents carry low latitude warm water to higher latitudes where the heat can be released to the atmosphere (through surface evaporation and sensible heat flux). ●In this way the latitudinal oceanic heat transport with its atmospheric counterpart (atmospheric Hadley Cell‚ Ferrell Cell and Polar Cell) to balance the Earth’s local heat budget. Loading... Oceanic circulations ●Buoyancy fluxes between air and water alter the density of the sea water - those are latent

EXAM 3 STUDY GUIDE 1. What is ocean gyre? • Any large system of rotating ocean currents‚ particularly those involved with large wind movements. 2. What drives surface ocean currents (how do they form)? • Wind is what drives ocean currents • As wind blows across water‚ they generate force on the water in the same direction that the wind is blowing. (only ~100 m of water is affected) 3. What is the other name for deep water circulation? • Thermohaline circulation 4. What is upwelling and

Chapter 16 Notes Lesson 1: Composition and Structure of Earth’s Oceans Water covers 70 percent of Earth’s surface. The five main bodies of water are: The Pacific Ocean is the largest and deepest ocean. It is larger than all of Earth’s combined land area. The Atlantic Ocean is half the size of the Pacific. It occupies about 20 percent of Earth’s surface. The Indian Ocean is between Africa‚ India‚ and the Indonesian Islands. It is the third largest ocean. The Southern Ocean surrounds
