What is Shark Diving?
Shark diving, or cage diving, allows divers, researchers and film crews to view the extraordinary world of Great White Sharks in comfort and safety. Specially designed shark viewing cages provide adequate protection for the sharks from sport divers, while allowing divers total freedom of movement and panoramic views. Our shark diving crews are industry professionals who care about your safety and enjoyment. Equally important, they care about making our dives safe for the sharks.
Is Shark Diving Dangerous?
To date, our most serious injury has been a sunburn. White sharks have many myths surrounding them. One is that they are killing machines attacking anything in sight. We have found that even at the height of a feeding event with multiple animals around a carcass, white sharks prove to be shy, slow moving animals. Our divers are amazed to learn first hand that these animals are almost gentle. That said, divers should always maintain a healthy respect for these awesome predators, in and out of the water!

HOW MUCH DAMAGE HAS HUMAN FISHING DONE TO THE OCEAN?
HOW MUCH DAMAGE HAS HUMAN FISHING DONE TO THE OCEAN?
We thought we could fish forever, because the sea was a limitless protein mine. But dawning now is a realization that we were wrong about that. But how naive were we? And what price will be paid? Ocean life is dying back in unexpected ways: although there are fewer fish and other sea animals, more of them are starving, while waves of 'sickness' spread as primitive microbes gain the upper hand. Symptoms include spreading 'dead zones,' harmful algae blooms and a diminished presence of sea animal life in general. Is fishing implicated in all of this?
Atlantic Canada reveals what is probably the clearest evidence anywhere of the ecosystem-effects of persistent human fishing. The early 1990's crash of the once great Canadian cod stock is held up as a global cautionary tale against fisheries mismanagement, against greedy human 'overfishing.' But less well known is that the story is not that simple, that, at the level of scientific detail, so much has gone severely and unexpectedly wrong in Atlantic Canada...that the most basic assumptions underlying the 'science of overfishing/sustainable fishing' must now be questioned.
Zooplankton were unexpectedly and inexplicably lost along with Canadian fish stocks. If, as seems likely, this is part of the ecosystem impact of fishing, then this finding has global significance.
Evidence: a Transformed Ecosystem
As the size and abundance of commercially targeted fish species has plunged in recent decades, populations of smaller, unexploited organisms, the 'foundation' species of the marine ecosystem, have also experienced major downshifts. Oceanic zooplankton is in decline, and NASA/NOAA has recently reported an apparent global declining trend in marine phytoplankton production. Evidence suggesting lowered marine nutrient cycling can also be seen along clean oceanic shorelines.
Example: A clean, rocky intertidal zone in Atlantic Canada was heavily dominated by barnacles (filter feeding animals) in summer, 1948, reflecting relatively high marine productivity at that time. (Photo from Stephenson and Stephenson 1954 J. Ecol. 42:14-70 ) Move mouse over photo to see this site in summer, 2002. Now dominated by rockweed with relatively sparse barnacle cover, with individual barnacles very small, this shift away from dominance by filter feeders, and towards dominance by seaweeds, offers classic evidence of a decline in "nitrogen loading" rates. (Carpenter and Capone, Nitrogen in the Marine Environment (Acad. Press, NY, 1983)) This pattern of shifting dominance from filter feeders to seaweed is also widely evident today in the tropics where mass coral bleaching and infectious coral epidemics signal the failing health of those once dominant filter feeders.

From "The Garden Island" Newspaper 2004
From "The Garden Island" Newspaper 2004.
With over a million people living in Hawaii and hundredsof thousands of tourists visiting yearly; Hawaiian huis, environmental groups, community members, and scientists alike are realizing that our marine resources are in trouble.
We need to know what our reefs look like and how abundant they are in different places around the island. Baseline surveys of our Marine Resources are imperative. What this means is that locals and scientists must examine the near shore marine coral reef as well as measure ocean health in offshore areas around each island. Baseline surveys are important to discover the health and abundance of animals on the reef, noting areas of importance and abundance, like where juvenile fish may shelter, turtle or monk seal areas, heavy coral spawning sites, other notable features as well as shoreline activity. Mapping the near shore with GPS (global positioning system), GIS (geographic information systems), as well as video and digital photo documentation can show the community what the reefs look like, provide an archive of the reef health if something was to harm it, and then let the community decide what is best for our reefs.
The state appointed stewards of Hawaii, the DLNR (Department of Land and Natural Resources) and DAR (Division of Aquatic Resources) have a severely limited budget, and their funding is constantly being cut. These men and women, local and introduced, are doing the best they can with what they have, and are working hard tohelp Hawaii protect our ocean and land.
Many local groups here on Kauai like Waipa, Limahuli Valley, Hanalei Watershed Hui, Malama Maha’ulepu, Nawiliwili Watershed Council, Save Our Seas, and Reef Check have seen that their own fish catch sizes decreasing, and less abundance of marine animals. They have already taken action and currently are monitoring and surveying local reefs, while training community members, and high school students in these techniques that support Ahupua’a, MPA (Marine Protected Area) and resource conservation projects. Currently, there are NO Marine Protected Areas on Kauai! All of the other islands have them, but we must ask ourselves why we have none here.
Marine Protected Areas have many different designations, some are Hawaiian Sustenance Fishing grounds where native Hawaiians may fish, some are Fish Replenishment and Management Areas, where fish are left by fisherman and collectors to recover and “seed” other areas as ocean currents take the young of these animals and spread them around the islands. Some MPA’s, like the tourist hot spot Hanauma Bay on Oahu, are Marine Life Conservation Districts and are completely protected areas only open to certain activities and even restrictions about fish feeding, litter, and suntan lotion apply. These areas are created by the community, for the community, and it is up to us to get together and make these Marine Protected Areas places that we all can agree on.
Efforts must be made to further educate fishermen on the successful programs already in place like the Ulua (jack trevally), Oio (bone fish), Opakapaka (pink snapper), and Ahi (yellow fin tuna) tagging programs. These programs show that many fish species move around and leave MPA reserves. Fisherman must also work with the communityto make rules and help enforce rules because our own government can not. Bottom fishing and “gill net task forces” must take action and find ways to create restrictions on themselves so that they may care for fish populations, our resources.
Mike Sakamoto, author and TV personality has proposed “a Fishing Task Force to look into a Marine License, smaller bag limits, slot limits, closed seasons on ulua and other species, an ulua enhancement program (stocking of ulua) and other enhancement programs…” as well as “Spear Fishing Task Forces” so that we the fishermen come up with size and bag limits, tournament restrictions, and night diving regulations. All of these ideas are a great way to increase and monitor populations, and the community certainly will be able to come up with more.
The management of Hawaii’s marine resources must evolve. Hawaii’s marine resources must be protected byus working together, with help from the state and federal agencies, to make sure that areas of high diversity are preserved and that future generations may have plentiful resources, we must create a bounty that will ensure the legacy of those that live on these islands

How polluted is Ocean Water?
How polluted is Ocean Water?
What kind of stuff is in it and why are some areas worse than others? Why are some areas dark colored black water and some are clear blue?
ANSWER?
Best Answer - Chosen by Asker
One of the most polluted sections of ocean in the world today is known as the Gulf Of Mexico "Dead Zone". Thanks to runoff from the Mississippi River, there is an extremely unhealthy cake of sediment and pollution in the ocean that covers an area of 22,126 square kilometres.
The majority of the pollutants that make up this particular Dead Zone are agricultural-based pollutants, eg. artificial fertilizer and animal waste. Thanks to meterological elements such as rain, the pollution makes its way into the tributaries that lead to the Mississippi, forming a big disgusting clump of waste just offshore in the Gulf.
This causes depleted oxygen levels in the water, which in turn leads to reproductive problems and ultimately death in marine wildlife.There are currently reports of over 140 dead zones throughout the world - but as pessimistic as this sounds, the good news is that the world's previous largest dead zone in the Black Sea (over 70,000 square kilometres!!) actually cleared itself up over the course of 10 years due to a decrease in industrial waste.I'm no ecologist so don't quote me on this - but I wouldn't think that dead zones are responsible for the darnkess of the sea water, I would have thought that had to do more with the ocean's depth and any reefs or other such natural geological occurance (ie. clear blue coloured water closer to the shore and darker black out in the deep, or in a reef-heavy area). Although I'm sure dead zones are distinguishable by satellite, I wouldn't think that *every* off-coloured part of the ocean is a polluted part.
