An umbrella for m-triton

In the drizzle, we deployed the first m-triton mooring of the cruise. The m-triton is an observation buoy that reports both surface atmosphere and ocean conditions. Having a line length that is greater than the sea depth, the m-triton mooring can adapt to the rapid currents in the Indian Ocean.

On the R/V Mirai, the engineers and crew handle m-triton with special care: never drag the line, walk out with the rope to pace the pay-out speed while others monitor gauges, shelter the water sensors from the equatorial heat, and use an umbrella to cover connectors when they are being joined to shield them from the frequent rain.
