Rollin’ in the Deep

This morning I was handed a small vial of water from the deepest reaches of the Tasman Sea (4800 meters deep, to be exact). So...

The Climes They Are a Changin’

Having collected another set of data from our familiar C2 site, we are now steaming to a location a bit south of the A1 mooring. Once there...

Two Ships Passing in the… TTIDE

Well, not just passing, but collaborating in a very unique way. By the time Falkor started steaming out of Hobart, the RV Revelle had been at sea for a...

Working in an Unpredictable Sea

Yesterday found me standing on the aft deck of Falkor, gripping a rope to hold the swinging CTD rosette steady as we lowered it over the side...

Calibration Celebration

Good scientific data is wonderful, but data is not very useful if it isn’t accurate. The tricky bit about using the ADCP on this cruise...

CTD’s Away!

Our first day of sailing consisted of voyage preparation. This included tying everything down and expecting the worst sea conditions. Pete and I managed to...

Catching the Wave!

A very big part of this project depends on a piece of equipment called the ADCP (acoustic Doppler current profiler). This is one of the...
