Callista trip

callista blog

 

Monday saw students go to Southampton where they participated in oceanographic activites.

They measured seawater temperature, salt content with expensive probes and then light penetration using Sechi discs.

A trawl net brought up shore crabs, spider crabs, sea sqirts, only a couple of slipper limpets as well as seaweeds and sponges.

Next we sniffed the mud brought up in a grab from 2 different sites – dont go wading off Fawley refinery; its ozzing with oil.  The clean stuff was full of oxygen and animals.

The plankton trawl was displayed using the boats lab microscopes and screens. 

We saw copepods http://academics.smcvt.edu/dfacey/AquaticBiology/Freshwater%20Pages/Copepods.html

and diatoms http://chsweb.lr.k12.nj.us/mstanley/outlines/protista/protists.htm which the fish feed on.

The University staff were great and let some of the students drive theboat.

Great day out.

    What was the seawater temperature? It’s supposed to be at its warmest at the moment, I believe so it would be interesting to see what is was! 🙂
