Hi terrikhnc,

I am not sure what the timezone is called, but we are two hours later than
Eastern Standard Time.

Here are two pictures of data generated by the CTD. One represents
optical data, showing PAR and transmissivity. PAR is photosynthetically
active radiation, or light that can be used by plants and phytoplankton
for photosynthesis. Transmissivity is a way to show how clear the water
is. You'll also see temperature on this graph. In this case you see a
warmer layer of water near the surface that is well mixed. The PAR
penetrates past this layer, so we deduce that the phytoplankton in this
layer are not light limited.






The other graph plots salinity, temperature and density with depth. We
can use this type of graph to look for indications of upwelling and for
characteristics of different water masses, such as melt run-off or
Antarctic Bottom Water.




here's a picture of the
seafloor that was taken from a camera strapped to the CTD. In it, you can
see an anemone and a soft coral (the round thing with no tentacles) called
Amthomastus. The two laser dots are about 15cm apart for scale.

And for all of you out there worried that the Lachat nutrient analyzer has
eaten Kim alive, we are all proud to say it is she who has conquered it.
