Endangered Species International Discarded fishing gear Discarded fishing gear such as monofilament fishing lines, sinker and hooks can entangle corals and abrade polyp tissue leading to coral lesions and mortality. In popular cast fishing spots in Oahu, Hawaii, scientists recorded fishing lines on 65% of 129 cauliflower coral (Pocillopora meandrina) colonies surveyed with increasing percentages of entirely or partially dead colonies being found in areas of with high percentages of colonies with fishing lines. A strong relationship was also found between the percentages of surface area with fishing lines and the percentage of dead surface area. Nutrients The health and diversity of coral reefs are threatened by excess nutrients carried into the ocean from the terrestrial and coastal zone. Increased levels of dissolved inorganic nitrogen (DIN as nitrate or ammonium) promote the rapid growth of species of algae such as crustose coralline algae and the macrophyta Lobophora variegate.

Marine Conservation Organizations MarineBio is deeply committed to marine conservation and founded on the concept that, by sharing the wonders of the ocean and marine life, people will be inspired to protect it. We hope you will consider becoming a MarineBio Conservation Society member to help us bring the ocean and the conservation message to as many people as possible. There are many other organizations working on marine conservation and other environmental issues such as biodiversity and global warming. We list them here both as a public service and to spread the word. Please Contact us if you have any comments, changes, or suggestions. » Invitation to fellow marine conservation groups For an objective annotated list of the organizations listed below and others, visit Mother Jones magazine's guide to environmental organizations The oceans are downstream of everything.

Picture that teaches you how to save the ocean Marine biology Only 29 percent of the world surface is land. The rest is ocean, home to the marine lifeforms. The oceans average nearly four kilometres in depth and are fringed with coastlines that run for 360,000 kilometres.[1][2] A large proportion of all life on Earth exists in the ocean. Exactly how large the proportion is unknown, since many ocean species are still to be discovered. Marine life is a vast resource, providing food, medicine, and raw materials, in addition to helping to support recreation and tourism all over the world. Many species are economically important to humans, including food fish (both finfish and shellfish). History[edit] The observations made in the first studies of marine biology fueled the age of discovery and exploration that followed. The creation of marine labs was important because marine scientists had places to conduct research and process their specimens from expeditions.
