(一)取样:取样时按 Samecto 和 Jaroszinski 所描述的方法(J·Eish.RES.BD.Canada,25,2240,1969),使用一个 Neuston 网来进行。这种网很轻便,容易操作。除了汹涌的大海外,在其他任何情况下都由船保持一定距离的拖曳,网的拖曳速度应以能使缓慢地掠扫一浬为宜。对于航行中的船只,应尽可能地每天都做取样工作。在固定观测点,取样可以以月为周期进行。取样昼夜都能进行。白天取样时,和样品同时捕获的有机微生物要减少。
(I) Sampling: Sampling was performed using the method described by Samecto and Jaroszinski (J. Eish. RES. BD. Canada, 25, 2240, 1969) using a Neuston mesh. The net is light and easy to operate. In addition to the turbulent sea, towed at a distance from the ship in any other situation, the web should be towed at a speed that will allow for a sweeping sweep. For ships in the loop, sampling should be done daily as much as possible. At fixed observation points, sampling can be performed on a monthly basis. Sampling can be carried out day and night. During daytime sampling, the amount of organic microorganisms captured simultaneously with the sample is reduced.
