How can \u003cb\u003eoceanography\u003c\/b\u003e help us? Or how it can influence our lives? \u003c\/p\u003e\u003cp\u003eOceanography, a combination of physical and biological sciences, may seem like an obscure or tedious subject, but it is fascinating and vitally important to know. It examines the plant and animal life in the oceans' depths as well as the conditions that exist there that are so extreme. For example, oceanographers study currents to predict weather patterns for us on land. Currents at the ocean floor seem to have an effect on weather patterns on land too.\u003c\/p\u003e\u003cp\u003eOceanographers are also studying how the oceans affect weather and climate. The more they understand about the oceans, the better we will be able to predict changes in climate that could impact us here on land. \u003c\/p\u003e\u003cp\u003eA record of sea level and temperatures of North American coastlines goes back thousands of years. At that point in time, the oceans were much more extensive, as you can see in this picture. \u003c\/p\u003e\u003cp\u003eIn the last few decades, oceanographers have been able to unlock some clues about how the world's oceans have changed over time by examining fossils.\u003c\/p\u003e\u003cp\u003eThis book covers\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOceanography\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eMarine Geography\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003eTides\u003c\/li\u003e\n\u003cli\u003eCurrents\u003c\/li\u003e\n\u003cli\u003eOcean Current and Climate\u003c\/li\u003e\n\u003cli\u003eWater Properties in the Ocean\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMarine Life\u003c\/b\u003e And The Environment\u003c\/li\u003e\n\u003cli\u003eEffects of Exploitation and Pollution on Ocean Ecosystems\u003c\/li\u003e\n\u003cli\u003eOceanography and Humanity\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAnd much more.\u003c\/p\u003e\u003cp\u003eMany sea creatures left traces of their existence in rock layers and layers of sediment that became part of Earth's crust. These rocks formed over millions of years, so there is a record from thousands of years ago to today.\u003c\/p\u003e\u003cp\u003eBecause of the geological clues found in fossils, oceanographers now know that the ocean's temperature has changed and continuously changed as time goes by. \u003c\/p\u003e\u003cp\u003eThe oceans take up a lot of heat from the sun. Water also holds more heat than air because it is much denser. Surprisingly, a slight change in temperature can cause considerable changes in water density because it is so sensitive to temperature changes.\u003c\/p\u003e\u003cp\u003eOceanography is essential for our health. Oceanic pollutants, for example, can be hazardous to many marine organisms and humans. \u003c\/p\u003e\u003cp\u003eThese pollutants can include mercury and pesticides that wash off of ships into the ocean and stay there for long periods of time before bacteria break them down into more minor compounds. These tiny compounds eventually make their way to the ocean floor, where they are taken up by phytoplankton in the ocean's water column.\u003c\/p\u003e\u003cp\u003eAnother pollutant found in the oceans is plastic. Plastic bags, packaging, synthetic fishing lines, and other items are polluting the ocean's water. Many studies underway determine how much of these pollutants are being taken up by sea life, and sooner or later, it will end up on our dinner plates.\u003c\/p\u003e\u003cp\u003eSea level change has been a critical focus for oceanographers because of its impact on human society. In addition to contributing to climate change, sea-level change is directly associated with flooding of coastal areas and erosion along river banks and mountain ranges.\u003c\/p\u003e\u003cp\u003eLearning about oceanography can help us understand the natural world around us because it combines chemistry, physics, biology, and marine science. Because of this, it is a great way to learn more about the world we live in.\u003c\/p\u003e\u003cbr\u003e","brand":"Independently Published","offers":[{"title":"Default Title","offer_id":51777342275858,"sku":"9798546514112","price":12.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/4771\/8930\/files\/img_2bb6a6dc-2816-4e7c-82ee-226e070877e9.jpg?v=1765361496","url":"https:\/\/surprise-castle.myshopify.com\/products\/oceanography-textbook-essentials-of-marine-science-9798546514112","provider":"Surprise Castle","version":"1.0","type":"link"}
