Callista 2010

Leah was a bit surprised to find we were going afloat on a boat!  She survived.

This is us being shown what lives on the bottom of Southampton Water and has been dredged up with a trawl net.

Fish – plaice and wrasse; spider, green, hermit & velvet crabs; green seaweed that is used to make toothpaste; sponges & sea squirts that made us wet, for starters.

We got to handle them.  We also measured the water temperature, salinity and the depth the light goes into the water with a thermometer probe and a sechi disc.  They dug up really rank mud from the oil refinery side, and animal rich mud from the wooded side of the Water.  Finally we used a big sieve to get the plankton, we saw these on screens linked to microscopes in the on board lab … all in 3 hours.
