Please don't push these divers that hard. Their capacity to help is limited.

If the debris is at depth it isn't divers that need to be in the water. They can only go to a very shallow depth and even at their deepest ability they are only allowed to be at those depths for a short period of time. It takes time to descend and then return to the surface without getting decompression sickness. 

I do not think this is a good idea.

Navy divers (click here) have been searching for parts of the missing Malaysia Airlines plane in the area where a signal was picked up.

The Ocean Shield ship picked up the signal twice, once for more than two hours, said Angus Houston, the retired air chief marshal leading the search.

He called it the "most promising lead" so far.

The plane, carrying 239 people, was flying from Kuala Lumpur to Beijing on 8 March when it disappeared.

There is no immunity to decompression illness. This is from DAN, Divers Alert Network. DAN is highly valued as a resource and advocate. They offer insurance and all sorts of services to divers. DAN has been around a long time.

Who Gets DCI? (click here)

Decompression illness affects scuba divers, aviators, astronauts and compressed-air workers. It occurs in approximately 1,000 U.S. scuba divers each year. Moreover, DCI hits randomly. The main risk factor for DCI is a reduction in ambient pressure, but there are other risk factors that will increase the chance of DCI occurring. These known risk factors are deep / long dives, cold water, hard exercise at depth, and rapid ascents.

Rapid ascents are closely linked to the risk of AGE. Other factors thought to increase the risk of DCI but for which evidence is not conclusive are obesity, dehydration, hard exercise immediately after surfacing, and pulmonary disease. In addition, there seem to be individual risk factors that have not yet been identified. This is why some divers seem to get DCI more frequently than others although they are following the same dive profile.

Since DCI is a random event, almost any dive profile can result in DCI, no matter how safe it seems. The reason is that the risk factors, both known and unknown, can influence the probability of DCI in myriad ways. Because of this, evaluation of a diver for possible decompression illness must be made on a case-by-case basis by evaluating the diver's signs and symptoms and not just based on the dive profile....
