This publication contains a report of the gravity at sea expeditions of the Netherlands Geodetic Commission in the years 1934 to 1939. It gives an account of the expeditions, the observations, the computation of the results and of their mean errors; the last table lists the gravity reduced to sea-level found at the 388 stations that have been occupied during these trips, thirty of which have been observed on land by means of a Holweck-Lejay apparatus. A following publication, Vol IV, will contain the isostatic reduction according to different methods of the gravity results of these and former expeditions at sea: it will include maps giving the location of the stations dealt with in this report and it will investigate different possibilities of interpreting the results.
The first chapter of this report gives a historical summary of the expeditions, the second deals with the expedition of Hr. Ms. K 18 from Holland to Java via Buenos Ayres, Cape Town and Fremantle in W. Australia, the third chapter with the expedition of Hr.Ms. 0 16 from Holland to Washington and back to Lisbon, the fourth chapter with the expedition of Hr. Ms. 0 12 from Curao to Holland, the expedition of Hr. Ms. 0 13 to the end of the Channel and the observations made on board of Hr. Ms. 0 19 in the North Sea, and the fifth and last chapter with a description of the tables I and II at the end of the report. Table I contains data and figures regarding the observations, the computations and their mean errors. Table I1 gives the positions of the stations, the sea-depths, the gravity results, their mean errors and the lengths of the waves encountered during submerging.
