一九三三年六月在加拿大Vancouver举行第五次太平洋科学会议(Fifer Pacific Science Congress)。关於海洋学组,各国分会皆早经成立,惟我国始终未着手组织。上届大会决定以国立中央研究院总干事为海洋学组中国分会主席。当前故总干事丁文江先生就任以後,即於一九三五年三月拟具名单组织中国分会同时并发起海洋渔业调查,推动植物研究所研究员伍献文博士为调资团团长。炯承丁先生之厚意,亦被邀参加。当时由丁先生商借第三舰队定海军舰作为调查之用。

According to the oceanic investigations, we have performed in the expedition from June to October, 1935, we see that the salinity at surface in Gulf of Pechihli is the lowest at the mouth of Yellow River, where the mean value of five months from June to October is below 26.5‰. Northeastward from here till Strait of Tengchow (Strait of Pechihli) the salinity increases from 25.5 to 30.7‰, there-fore the gradient is rather steep (ChartⅠ.), At the mouth of Lwon-ho the salinity is also lower than that of middle part of the gulf, but the influence is naturally not so prominent as that of Yellow River.
