Sampling the rosette

CTD rosettes are used to collect water samples from predetermined depths of the ocean. From Jim Swift: "the science

team is busy collecting water samples from their

chosen levels. There are up to 21 individual

water samples drawn from each 30-liter bottle,

some of which are up to 20 liters in volume, so

it can be necessary at times to close 3 of the

bottles at one level. Other times as few as 6-8

water samples are drawn from a bottle ... it's

all a matter of which science team needs water

from which level at which station."
