Kimura's last time in the field

My first graduate student, completed his masters and left the lab in March. He works for a big construction / environmental assessment company now, and is in Tokyo. Anyways, we went out for one of the last surveys of the season in Omura Bay. I don't really remember but I think the water was about 8 degrees C. It not that bad, as long as the sun is shining and the wind is not blowing.

Here you can see our surface buoy with the anemometer and the PAR sensor. Both of which are from Onset. Kimura is using a Castaway CTD from YSI to take salinity and temperature measurements. We like the Castaway, because of its ease of use and the fact that it will take write some GPS information to the data recording. Not to mention the fact that we can see the results immediately in the field. The only problem is that periodically it is difficult to "wake up" the instrument. Sometimes it fails to turn on. But after a few minutes fiddling with it, then it will turn on. I haven't bothered to ask anyone about it yet.

We also have a PhD student with us, she is just to the left of the ladder. She is from Thai and is part of an affiliated lab. She just so happens to use the same field site as us, so we bring her along so that she can do her work. She usually uses a wader and just collects water samples and measures the length of Sargassum thumbergii, even though we got her snorkeling gear. I haven't seen her stick her head underwater since the summer.

This is what Sargassum thumbergii looks like during January. It is still a bit small and is not mature yet. I'd say that this group is about 40 cm or so. They will end up as long as 80 cm by May. It is called ウミトラノオ in Japanese, which roughly translates to "sea tiger's tail".
