Reverse Osmosis: Getting Drinkable Water from the Sea

Water, water, everywhere – but not a drop to drink. How do you get fresh water on a ship? You could bring it with you – but water is heavy, and you would be severely limited on how much you could use for any given purpose. Drinking, washing, showering, cooking – that’s a lot for...

The cruise track so far …

Back onshore, John has quickly plotted the voyage track to date and the stations where we’ve stopped for CTDs, cores or multicores (the blue squares on the map). As you can see, we are WAY out there halfway to Africa. If we were to steam straight home now it would take us about 8 days...

There is work to do even on windy days

We’ve been waiting for the wind to die down for almost 2 days… but that doesn’t mean we haven’t been busy. Although we can’t core we can do a lot of other things – like search with our sub-bottom profiler for more locations – which took us back by Ile Amsterdam – where the petrels...

The Galley Staff

We might be out here for science, but what keeps us out here are the ship’s crew. Without them, we would be a bunch of scientists (and one science writer) with a lot of luggage and a lot of good ideas. Some of the most obvious contributions are made a minimum of three times a...

Algae, Tweets, and Whales

Last night we were treated to a large red algae bloom just as the sun was setting. Long, thick tendrils of maroon phytoplankton reached out all around us, converging and diverging according to some current or other. We collected some samples – including some copapods, little water bugs, which had turned red. You are what...

Good weather…. It had to end sometime.

Good weather…. It had to end… We have had a fabulous couple of days of coring — 3 cores in one day and 4 in the other – All we did for 3 days was core and core again.  But the weather changed yesterday, a front came through and it began to blow – and...

Rough Seas

The past two days have been characterized by a significant change in weather. The sea state has gone from about 4 to maybe 6 or 7 – lots of white caps, larger swells, and a strong wind. We’re on the tail end of a front, which explains it – but explaining it doesn’t help us...
