什么潜水协会都是一样的，你可以 cross over 去 PADI 就是一个很好的证明。

为什么失望呢？
你的教练教得不好吗？

其实如阿鲨讲的，并不关潜水协会的事的。。全部潜水学会都是一样的。。。只是名字不一样而已。。。不然就是教练偷懒。。。

请问你想做什么呢？什么都看不到的？

我想他要放照片. 但是他直接从自己的电脑LINK上来, 所以失败了.

我的equalize 问题怎样？我用按鼻子。。。左右手都试了。。。
咬摇下巴。。。都试了。。。。
问题就是慢equalize 。。。

你试过吞口水，摇头等动作吗？不然就升高一点从新做过 equalization。再不行的话，你就要见一见耳鼻喉医生了。

2。潜水时可以/需要搽防晒油吗？？因为我姐姐很怕晒黑。。 ...

其实最好的话就不要涂防晒油，防晒油破坏海里的生物，尤其是珊瑚。

Swimmers' Sunscreen Killing Off Coral

Ker Than for National Geographic News

January 29, 2008

The sunscreen that you dutifully slather on before a swim on the beach may be protecting your body—but a new study finds that the chemicals are also killing coral reefs worldwide. Four commonly found sunscreen ingredients can awaken dormant viruses in the symbiotic algae called zooxanthellae that live inside reef-building coral species. The chemicals cause the viruses to replicate until their algae hosts explode, spilling viruses into the surrounding seawater, where they can infect neighboring coral communities. Zooxanthellae provide coral with food energy through photosynthesis and contribute to the organisms' vibrant color. Without them, the coral "bleaches"—turns white—and dies. "The algae that live in the coral tissue and feed these animals explode or are just released by the tissue, thus leaving naked the skeleton of the coral," said study leader Roberto Danovaro of the Polytechnic University of Marche in Italy. The researchers estimate that 4,000 to 6,000 metric tons of sunscreen wash off swimmers annually in oceans worldwide, and that up to 10 percent of coral reefs are threatened by sunscreen-induced bleaching. The study appeared online in the journal Environmental Health Perspectives. Activated Viruses Danovaro and his team studied the effects of sunscreen exposure on coral samples from reefs in the Pacific, Atlantic, and Indian Oceans. Even low levels of sunscreen, at or below the typical amount used by swimmers, could activate the algae viruses and completely bleach coral in just four days, the results showed. Seawater surrounding coral exposed to sunscreen contained up to 15 times more viruses than unexposed samples. Several brands of popular sunscreens were tested and all had four ingredients in common: paraben, cinnamate, benzophenone, and a camphor derivative. Dangerous Dose Robert van Woesik, a coral expert at the Florida Institute of Technology, was not involved in the research. He questions whether conditions in the study accurately reflect those found in nature. For example, the coral samples were exposed to sunscreen while in plastic bags to avoid contaminating the reefs. But van Woesik worries this prevented dilution of the chemicals through natural water circulation. "Under normal situations on a coral reef, corals would not be subjected to these high concentrations because of rapid dilution," van Woesik said. But according to study author Danovaro, the effect is not dose dependent—so coral's exposure to a very small dose of sunscreen is just as dangerous as a high exposure. "It is more like on-off," he said. "Once the viral epidemic is started, it is not a problem of toxicity." Alarming Trend Rebecca Vega Thurber, a marine virus and coral researcher at San Diego State University in California, said the new results are further evidence of an alarming trend. "Other [human-induced] factors such as coastal pollution, overfishing, and sedimentation all contribute to coral reef habitat degradation, and this work continues in that vein," said Vega Thurber, who was also not involved in the research. (Related news: "Coral Reefs Vanishing Faster Than Rain Forests" [August 7, 2007].) "But before we ban sunscreens, we must first determine if local ambient concentrations of sunscreens are positively correlated with coral bleaching events." Danovaro says banning sunscreen won't be necessary, and points out two simple things swimmers can do to reduce their impact on coral: Use sunscreens with physical filters, which reflect instead of absorb ultraviolet radiation; and use eco-friendly chemical sunscreens. (Read about other ways you can protect the oceans.) Australian researchers are also working to develop a sunscreen based on a natural ultraviolet-blocking compound found in coral. http://news.nationalgeographic.com/news/pf/82923650.html

你不要等到耳朵疼才吹气。。。感到有一点压力的时候就赶快吹。。
压力越大越难吹哦。。。
当你要吹气得时候，按着鼻子用力吹。。。
还有下去的时候不要太快，让自己的耳朵慢慢适应。。。。

不然就浮上去，再慢慢下去。。。
你有跟你的导师讲吗？

机车女孩

我的学长现在也是在tioman做着着个研究。。
看防晒油对珊胡焦的破坏。。。
不过还不知道结果是怎样。。。

寡佬

支持你的说法！
怕晒的话，可穿件长袖衣或rush guard
但如果是美女又穿bikini的话！
那就算了！

搽不搽防晒油我是不介意。。
因为前3年一直参与步操训练。。
已经被晒到好像碳酱。。
再怎样晒也晒不伤我。。
更不可能再变黑了。。
只是我姐姐，被我们全家称为爱美婆。。
他一决定要去学潜水。。
就在找哪个防晒油牌子好。。
还要买sunplay那个SPF130的。。
不过我也很怀疑。。
SPF可以到130酱高吗？？
上次跟朋友去tioman浮潜，我其他朋友全部共用那个SPF130的，结果全部晒伤了，脱皮。。
只有我一个相安无事。。
我在劝姐姐不要买那个SPF130的时候，跟他讲了这个例子。。
结果他还讲，脱皮就是没有黑到啦。。
晕死。。
竟然不在意晒伤的痛，只在意有没有变黑。。
很难叫他不用防晒油哦~~

如何把post 照片,为什么不能的？

如果是这样的话 ，搽少点 或 薄点 。。。

期待你学长的研究报考， 毕竟很难在网上找到有相关的资料

买RASH GUARD是更好的选择。
