Physical oceanography during John P. Tully cruise IOS-96-01

c=beamc-adjc, 1-m pathlength SeaTech transmissometer at 660 nm data are reproducible to better than 0.001 in deep water. Clear water value for c is 0.364.采用1米光程的SeaTech透射仪测得的660纳米波长下的校正后光束衰减值（beamc-adjc）对应的光束衰减系数c，在深水中的测量重现性优于0.001；该参数在清水条件下的基准值为0.364。
