at the ten consecutively numbered stations: indicated in Figure 1," ranging along the southern and eastern portions of the iagoon, both plankton and bottom material were sampled. At the first four a: a. stations sea water was pumped from astern of the "Aloto" by means of a high-speed, gasoline powered, fireffighting’ pump with 3 capacity of about 4O gallons per minute, while at the other six stations .7# Mes @ more reliable, submersibie, electric painp Sberating alongside the ship gave 180 gallons per minute. t .. es Pumping continued for 30 minutes ie ‘< i oS with the mouth of the net above water, a0. 0.that‘a11‘pumped water went through the net. Pumping, as here done, although norequantitative, was less | desirable than towing for two reasons. ��Smallersamples of plankton were obtained, and debris from the ship seeed unavoidable. Preservation of tne plankton was in ‘areohorexcept for the tows in Au,pist near Kabpelle Island. Here the bucket was removed from the r 2 net and tie end of the net tied closed. After towing, the net was washed down, drained, untied, and the plankton boraped directly into small plastic Lags in which it was later dried at‘Bote. without preservative. Tnis simplification avoided the almost inevitable leakage 3 at the ba;-onet- type fitting of the planktonbucket, and expedited the processing; it 1s recomended where radio-“assay is the primary objective. For laboratory processing of the March 1958 samples, the pre- — servative fluid was filtered from the plankton and tested for radioye activity (practically lacking) before discarding.
