Sampling’s weather…

As Lisa wrote in the last post, since the experimental period started, the weather isn’t very nice… Actually it’s the 4th day of sampling and sun didn’t really shows up since…

  • Thursday (1st day) wasn’t too bad (the rain arrived after the samplings);
  • Friday the same type of weather but for the first 5am sampling of the experiment it was very cold;
  • Saturday rain for the 8.30am sampling and wind for the 10.30 sampling;
  • Today: rain started with the 5am sampling and still haven’t stopped. On top of this we have a nice swell entering the bay (very bad for mesocosms)… Not very easy to do our job in these conditions….

At 7am this morning when the light of the day arrived, what did we see on the montains behind Villefranche: snow!!

Also very impressive weather events was on Thursday around 4pm during 2-3 hours rain and thunder storm settle in the bay… This give very nice pictures and hopefully we didn’t have sampling at this time of the day:

Can you see the mesocosms?? A bit hard..

Can you see the mesocosms?? A bit hard.. (thursday afternoon storm).

It’s maybe time to explain how our days are made with. We have a 2 days cycle: Day 1 and Day 2.

On D1 & D2 there is the 8.30 am sampling for what we call ‘core parameters’: carbonate chemistry; pigments; nutrient; particulate organic carbon, phosphorus and nitrogen; … And the CTD (Conductivity Temperature Depth instrument) cast at 11am.

Than, on Day 1 there is, in addition of the normal sampling, the 10.30am for every two days parameters such as taxonomy and coccolithophores assemblages.
On D2, there is the 5am sampling for processes. In this we have all the nitrogen fixation realized by Plymouth Marine Laboratory (see Lisa post, Friday 22nd); microbial metabolism (OGS Italia); Viral Production (HCMR, Greece) and Primary Production (local team).

This is a little bit of organization (who is going when, prepare the boxes, put the right bottles into the boxes …) but in few days (if the weather get a little bit better) everything will run like clockwork!!
