Complete I5 trackline

R/V Roger Revelle Complete, final trackline of CLIVAR line I5 across the Indian Ocean. What a ride!

CLIVAR I5 Final Science Report

In port in Fremantle, Australia

Yesterday afternoon we completed our 195th CTD/rosette station, with SIO Research Technician David Langner helping Jim cut the CTD cable afterwards - no more stations!

Captain Tom Desjardins brought R/V Roger Revelle to the dock at Fremantle, Australia, at 0845 local time this morning, bringing to a close this reoccupation of WOCE Section "I05" for the CLIVAR/CO2 Repeat Hydrography Program, after 55 UNOLS days at sea, rather than the allotted 57. No one complained about the early arrival.

We completed every planned station (and a "bonus" station or two) without a single aborted cast or any blocks of missed data for any program parameter. We cannot recall such a trouble-free cruise previously during our careers.

To generate this unparalleled degree of success has meant long hours and repetitive station work from beginning to end. The officers and crew of the Revelle proved that they are more than equal to the task. It has truly been a pleasure to work with them on their home and workplace at sea. We have been welcome, well supported, comfortable, and very well fed.

The measurement teams have worked hard indeed. The dedication, commitment, doggedness, expertise, professionalism, pride, and good humor that everyone on board has brought to their work has made this cruise the success that it is.

However, it has also in many ways been as easy and pleasant a cruise as any, mostly because everyone - Ship's Officers, Crew, and Science Party alike - has worked so well as a team over the past two months. The result this endeavor is a truly world-class oceanographic data set that will be analyzed for decades to come. Our warmest thanks to each and all aboard! What a great group!

We are very grateful to NSF and NOAA, and our program managers there, for the support, advice, and encouragement that continues to make this program a success.

We choose to close with a little ditty (to be sung to the tune of "I'm a Little Teapot"). "The I05 2009 Sampling Song" composed in the early morning hours late in the cruise.

I'm a Niskin bottle,
Tall and thin.
I'm made of plastic,
Not of tin.

When I reach the surface,
Haul me in.
Strap me down,
Tap the water within.
