Oceans

Oceans
Food, work, fun, adventure, sport and life – not many things can give us all those things in one. Every day the oceans give us the air we need to breathe; the weather to grow crops; water to support the smallest to the largest animals on earth and 80% of all species; vast ice flows to help regulate our climate; millions of jobs and a life-time of pleasure. Send us your favourite ocean image and it could be featured here! You and I are alive right now because of the oceans. They are home to the largest animal our planet has ever known – the now-endangered blue whale - but there are still huge areas of ocean that humans have never seen. Earth's longest mountain range is not on land but under the sea - the Mid-Oceanic ridge system, which winds around the globe from the Arctic Ocean to the Atlantic. More people have stood on the moon than dived the deepest ocean trench and less than 5% of all the oceans have been explored. We can do it. The oceans support billions of us.

Main Page - Coastal Wiki Oceanography Driven by forces such as wind, tides, and gravity, currents keep our oceans in constant motion. Currents move large amounts of water great distances. Countless currents have been named, but the seven major ones are the West Wind Drift (or the Antarctic Circumpolar Current), East Wind Drift, the North and South Equatorial currents, the Peru Current, the Kuroshio Current and the Gulf Stream. These currents flow in large rotating loops called gyres. In the Northern Hemisphere, gyres spin in a clockwise direction, and in the Southern Hemisphere, gyres spin in a counterclockwise direction. Large surface currents are mainly driven by winds that blow year round. Two of the largest currents are the Antarctic Circumpolar Current and the Kuroshio Current. The Gulf Stream is a current with a strong influence on the East Coast of the United States.

Recycle This - Creative ideas for reusing and recycling random stuff Overfishing 101: How Ocean Fish Populations are Managed in the U.S. – National Geographic News Watch In the second post of a special series to mark the 35th anniversary of the U.S. Magnuson-Stevens Fishery Conservation and Management Act, a law that is helping to rebuild America’s depleted ocean fish populations and ensure their long-term sustainability, Lee Crockett looks at some of the basics of why all Americans should care about how our fish are managed. By Lee Crockett Fish are an essential component of life in the world’s oceans, with the state of their populations serving as a bellwether of the health of ocean life overall. Unfortunately, many species around the world are in trouble. Pollution, habitat destruction and overfishing (removing fish from the ocean faster than they can reproduce) have impoverished our oceans. All too often the discussion around the issue of overfishing has been limited to a small group of stakeholders such as fishermen, conservationists and scientists.

10 Ways to Help Save the Ocean Meghan MacGillivray, Sarah Bedolfe, and Sarah Wilson | October 08 2012 The ocean is massive, and a lot of the problems facing it are too. It can feel overwhelming to look at these issues. Here are a few things that you and I can do, on an individual level, to help make change. Eat Sustainable Seafood: Overfishing is a global problem, and many common fishing and farming methods result in major habitat damage or large amounts of bycatch – other species are caught unintentionally and are often thrown back dead. Use a seafood guide when ordering or purchasing to help make sustainable (and delicious!) Dolphin safe label The concept of dolphin-safe tuna labeling originates in the United States.[1] The labels have become increasingly controversial since their introduction, particularly among sustainability groups in the U.S. Various dolphin-safe labels are used to denote compliance with various laws or policies designed to minimize dolphin fatalities during fishing for tuna destined for canning. Some labels impose stricter requirements than others. According to the U.S. Background[edit] Dolphins are a common by-catch in tuna fisheries, especially in the Eastern Tropical Pacific Ocean, as they commonly swim with schools of yellowfin tuna. Dolphins do not associate with Skipjack tuna and this species is most likely to be truly "dolphin safe".[2] However, the species of tuna is not always mentioned on the can. Criticism[edit] Definition[edit] In a 2008 report, Greenpeace notes dolphin-safe labels may make consumers believe the relevant tuna is environmentally friendly. Pricing[edit] Non-dolphin bycatch[edit]

Oceanography Sometimes currents occur along the coast and only affect small areas. One current found along the coast is the Longshore Current. This current is caused when waves strike the beach at an angle. The front part of the wave hits the shallow water first and slows down. The rest of the wave bends as it comes onto the shore creating a current that parallels the beach. Rip currents are a potentially dangerous effect of Longshore currents. One type of vertical current is called a coastal upwelling. Downwelling is another coastal happening.

McDonald's ocean rescue: Sea change or greenwash? 6 October 2011Last updated at 08:19 By Kate Forbes BBC News Experts seem to think the little blue label can have a big impact Think of your most ethical friends. The ones who order organic or fairtrade. Would they be seen in McDonald's? Europe, and the UK in particular, is increasingly seen as a place where being greener is good business sense. Campaigns by various organisations and celebrity chefs have raised awareness of sustainable food, and the latest company to sit up and take notice is the fast-food giant McDonald's. From this month, all of McDonald's Filet-O-Fish sandwiches sold in Europe will now bear a label from the Marine Stewardship Council (MSC), a British environmental watchdog, certifying that the fish used was caught in a sustainable way. In plain English? And each one will carry a label on the box to tell us so - much like fairtrade-certified coffee, or beef from cattle raised on land that does not threaten the rainforest.
