First Paragraph
In October 1967, Jean Filloux obtained a tidal pressure record on the deep sea floor off California (see Fig. 1 for locations), using a Bourdon-tube pressure sensor and a time-release device for recovery (Filloux, 1969). In summer 1968, Frank Snodgrass dropped capsules Josie, Kathy and Flicki with Vibrotron pressure gauges; the capsules were acoustically recalled after a month (we believe this was the first time this technique was used), These four records, together with a Lamont station 100 miles offshore to the north and cable-connected to shore (Nowroozi et al. 1966) provided the information required for constructing a rough co-tidal chart (Munk et al., 1969).
