The unit for salinity is commonly g.l-1, but to be right, how we must write :
ie: 35 °/°° or 0.0035kg.kg-1 or 35 g.l-1 or 35 ?
Thank you for your help

I've investigated commercially available wave height measurement
instruments and found they are way too expensive for the yacht club.
Consequently I've built an ultrasonic wave height instrument which seems ...

Several months ago, whilst on holiday my wife and I visited a beach in Wales
and found an interesting 'creature' which we could not identify.

I had an argument with my geography teacher on the topic of how
such large amounts of salt (we had been reading a text, in which
one calculation said, that if the waters of all oceans evaporated,
a 70 metres thick layer of salt would cover the ground) could have

Is there anyway to predict or monitor where one could find new volcanic
islands surfacing?
Thanks,
