KAUST Red Sea Expedition - Spring 2010

While the economic and environmental importance of the Red Sea has long been recognized, our knowledge of its hydrography, microbial diversity and physicochemical properties remains inadequate. In March 2010, KAUST, together with its Global Collaborative Partners, launched its second major marine research expedition, KAUST Red Sea Expedition Spring 2010. Following up on the discoveries of KAUST Expedition Fall 2008, the expedition aims at investigating fundamental aspects of the oceanography and deep-sea environment of the Red Sea. The cruise has been subdivided into three “legs”, each following specific research goals.

R/W Aegaeo

The final day of sampling and we encounter problems with the weather and the equipment. We got in a few casts before the weather got so bad the Captain once again halted casts. But we did notice that the lanyards, as a result of the constant exposure to heat in the brines, began to warp. So any that looked iffy were replaced with brand new ones.

After 4 hours waiting it was deemed that we could try once more. The wave action, however, had reduced some of the slack in the wire causing 18 of the 24 bottles to misfire. So once back onboard we set everything up once more for a final cast and slowly lowered the package into the water.

Although it was taxing, we ended the sampling on a fully successful cast that hit the mark and all bottles fired properly. On such a positive note we set course for KAUST Harbor to arrive about midday on the 14th.

Interesting Fact: Onboard the vessel we not only had English, Arabic and Greek being spoken at all times but we also had the occasional conversations in German, Portuguese, Spanish and Cantonese.

Things are going well. The scientists from each organization have specified precisely what temperature and salinity ranges they desire samples from and as a result of the data obtained via the HRCTD and Star Oddi tags we have been succeeding with each cast. ... read more
