I came across this article on the BBC recently and it struck me as an excellent idea and one in which sailors could make a contribution with very little effort. It's a simple device to measure plankton for Plymouth University and this is part of what they say:
The marine phytoplankton account for approximately 50% of all
photosynthesis on Earth and, through the plankton food web that they
support, they both underpin the marine food chain and play a central
role in the global carbon cycle strongly influencing the Earth’s
climate.
Living at the surface of the sea the phytoplankton are particularly
sensitive to changes in sea surface temperature. A recent study of
global phytoplankton abundance over the last century concluded that
global phytoplankton concentrations have declined due to rising sea
surface temperatures as a consequence of current climate change....

this second link has an additional link to downloading a mobile app to report the data you find. Apart from a phone they ask you to make a white 30cm disc, called a Secchi, take a reading between 10 and 2pm and a few other small points - well you can read about it in detail on the second site. Seems a great idea to harness those already out there on the oceans to provide valuable data. Most yotties I know seem to have mobile phones so no reason not to get involved....

Here we go again...
It's 5.30pm, high water was about an hour ago and yet the water continues to rise...we're in the middle of, yet another, winter storm and the NW wind blowing around 35knots with, apparently, possible gusts of 45 knots from the NW. The worst direction in Scott's Creek and a chop has built up which will probably increase as the tides tries to ebb.
Bee has just leapt off the boat in her wellies to collect a parcel our friend Cary has been expecting. The UPS driver was alarmed to see the wild haired woman trying to run through the water that has already risen above the jetty... and couldn't work out why anyone would be coming from that direction in this weather....
As luck would have it we have both the Carrie B and a local ferry in alongside us. Unfortunately the jetty they're on is really only long enough for one vessel so the Carrie B has about a third of its length against the jetty whilst the rest remain in limbo. Lets hope both the jetty and their lines hold or this place is going to look like a skittle alley.
I think it'll be a long night.
But it has been quiet and restful, well perhaps not for this fish. At the moment the top of this piling is struggling to stay above water as it continues to rise.
