. Discovery reports. Discovery (Ship); Scientific expeditions; Ocean; Antarctica; Falkland Islands. 40 DISCOVERY REPORTS allows the computation of the dynamic heights of the sea surface and other isobaric surfaces at shallow stations relatively to those at deep stations. Prior to the construction of the vertical section of specific volume anomaly, the curves of the distribution of temperature, salinity and density with depth were drawn. In a few cases the values of temperature and salinity were smoothed when this was necessary, and this was done in such a manner that the interpolated values of temperature and salinity were in good agreement with the density and specific volume anomaly curves. The dynamic depths of the various isobaric surfaces are calculated in the usual manner, adding to the known values of the specific volume those which have been artificially obtained in the manner described above. Fig. 51 illustrates the method for obtaining the extra values of specific volume anomaly. From the dynamic calculations one station could be selected at which the level of the surface of the sea was lowest, i.e. the most dense water occurred at this station. By taking the dynamic depths above the datum level it was then possible to obtain relative 7. Fig. 51.

Occasionally a datum station was chosen which was not that of the most dense water. When the height of the sea surface above the datum isostere at a station was lower than that of the datum station, this was expressed as a minus difference of level in dynamic centimetres. The two principal lines of stations in the Bransfield Strait were from King George Island and from Livingston Island to Trinity Peninsula. By use of the Helland-Hansen and Nansen method the relative height of the sea surface at stations a
