Sampling with wind conditions at least 15 kt has become very usual for the MedSea mesocosm team and we are now able to work such very difficult conditions. It is amazing and the participants are amazing on their cubi. We have put diving weights in the samples boxes to avoid any flying boxes to the water! Yes, we have been experiencing high winds since several days now and yes, we are ok but most surprisingly, the mesocosms are still in very good shape and no damage were found by our diving team (Amélie and Sylvain) who go to the mesocosms everyday to change the sediment traps. As they go under water from the Stareso station using funny ‘underwater scooter’, they could go to the site, even yesterday. They said it was very nice and calm at 15 m depth! Indeed yesterday, the wind was so strong that we were not able to go out with the boat as the security was concerned. We have been deciding on the sampling strategy by following very carefully the forecast: for those who are used to sail in the Med Sea, they know as the wind can change rapidly, and as it can increase its speed even more rapidly. We have a ‘Special Forecast Warning’ since 4 days now and it seems difficult in the present condition to predict what will really happen in term of wind …. Apparently, the worse has to come as they predict a huge wind event for tomorrow (figure from http://www.lamma.rete.toscana.it/meteo/modelli/vento-e-mare)… Huh, no doubt that tomorrow will be a quiet day in the labs, except for the incubated samples that hopefully we will be able to withdraw quickly with the rubber boat early tomorrow morning!
Apart from being quite annoying for our daily sampling routine, this event is going to be very interesting in term of results as a specific forcing on the structure of the surface mixed layer, on the air-sea exchanges and on the functioning of the ecosystem.
