by the joint gr^-vit^ expedition of the ■M"'.v-'^-l Observatory^ ^nd of f-^e 

 Cnrnogie Institution, bv present cooperation with the Scripps In- 

 stitution in f^e stTidy of the srufaco te-Tipor^.tnros of the Pncific, 

 r.nd by adoption of f^o roconrriend""tions , lust qnoted, th'-i-t-. the ocenn- 

 ogrnphic "ctivities of the Nnw be extended. In s'-^ort, •.■.'(5 'r^ n.s~ 

 sured th'-'t +"ho active interest in Ocennog;rrphy expressed " '" th-i Con- 

 feronco at the V.o.vr D.'p' rtment in 192^ h^s not deereased. 



But these favoring factors r ru partlv counterbalrnced by the 

 imnossibilit^' of the I'lav^^J-'s fin'^ncing any special occ^nograahic 

 cruises fi^o'^i present approprin tions • and by the improbability that 

 Congress will Incre-'ise the l.'^tter for this purpose. 



In short, it is only in the following fields thr-t active las- 

 istance c^n be exaected from the Navy at r^resent' 



(a) Routine observr. t lonc stich as can be taken on the regulrr 

 cruises either b'^- t'TO ship's personnel or by observers detailed 

 from some scienti.'^ic institution, without "ddlng materially to the 

 cost of operating the ship. Projects of this class include the 

 gravity m.easuroraents just mentioned, the colleoticn of surface tem- 

 peratures, meteorological data. a.nd echo sounding. A promising de- 

 velopment I'.'ould be the; installation of recording f-'-ermogra-'hs , es- 

 pecially on the transports running to the Philippines and Hnwaii 

 (pnge ). 



(b) Occasional topographic surveys of srecial araas of the 

 sea bottom. 



(c) p.^rticip" ting in general oce'~nofTi'-""phic progr'^m^s b^- t'le 

 Hydrogranhic Of'f'ice in a direction'",'^ or an advisory cap'^citv. Al- 

 though onl^" a susfjestion of this is 'lossible here, it offers in- 

 teresting possib] ities. 



(d) Assistance from. V-^o Naval Research Labor^torv in the dr.-v- 

 elonment of pcoustic r.nd other apparatus.

It is obvious tlmt thcj policT that the Congress of the United 

 ot'^tos decides to pursue with regard to t' e operatior, or disposnl 

 of t--.v American Mercantile Marine will determine what cooperation 

 is to be expected under this heading. 



But so long as i-he Shipping Board continues to oper :te vessels 

 on the principal tmdv rou.tes of the v/orld, it is in r position to 

 render peculiar rervices to Ocennographh. Fo refer h^^re to the con- 

 tinuoui.s record of the surface temperatures of the se-^ by recording 

 thermographs, coincident with record of the temperatu.re of +-he 

 overlying air, and of the atmospheric barometric pressure to other 

 records of tem.pera turo, and t^^e collection of samples of the sur- 

 face w-tor "s ou^" lined nbove (P-ffe ">
