DAy 23 - 4th July 2012
Sea Dragon is now 24N 17” 164W 44” and slowly reaching towards Maui. This last stretch is taking time, beating against the wind and motor-sailing if the wind drops. Our course takes us close to Necker Island, a small rocky outcrop which supports hundreds of frigate birds.
We are looking to arrive five to six days later than schedule (perhaps on the 7th..) and have ceased trawling for plastic after the trawl was found to be acting as a sea anchor and slowing the boat by up to 20%! It is unfortunate to stop sampling, though expedition members have flights to catch and family to meet. I think I may be the only one content to keep sailing, each sunrise is beautiful, the North Pacific rollers forming the perfect foreground for the painted skies.
This expedition has planted the seed for Two Hands Project to sample for plastic at sea offshore around Australia, if you’d be interested in joining such an expedition drop us a line, particularly if you own a seaworthy yacht! ;-)
Last entry I asked for any questions about the expedition, and some great ones have come in, mostly concerning radioactivity from Fukushima.
-Is any of the debris radioactive? We have a Geiger counter on board and have been taking readings from the tsunami debris we’ve recovered, all have been within normal limits (I even took normal readings off my sneakers which I wore while volunteering within the exclusion zone around the reactor …I was kind of disappointed they weren’t a little bit hot;) So far we have not recovered anything our instruments have shown to be above normal radioactivity levels.
-Is the seawater in the North Pacific radioactive? Last year Woods Hole found unusual spikes in the levels of Cesium in the waters off Japan, the 5 Gyres/Algalita Tsunami Debris Expedition has been collecting water samples as a follow up study, we will have to wait on the results from the lab to see whether levels are still elevated.
-How much tsunami debris is out there? This is really hard to quantify, so I won’t even try. It is a substantial amount though. As for the ratio of tsunami debris to plastic pollution in the North Pacific I would be surprised if more than 2% of what is out here is tsunami related. ( Which means there is an enormous amount of plastic out here!
-What do you miss most while at sea? Fresh fruit and vegetables, good cheese and rye bread. Beer.. That about sums it up. I hope I can find a good beer in Maui.. Next voyage I’d like to do with all the Two Hands Project team on board :)
-Are there really plastic toothbrushes in the middle of the ocean? Yes! We’ve recovered two and spotted more. ( not mine! I have a Bamboo Toothbrush :-) We’ve also recovered a hair-comb and cotton bud (Q-tip)
Just heard our fuel is down to 550 litres, less than a third of our capacity, so we’ll cut back on the motor sailing for a few days and make way wholly under sail. To me that’s great news, as long as we get to Maui by the 7th, it’s so much nicer sailing rather than motoring.
