Cruise summary report
|Ship name||Sand Pebbler|
|Cruise period||1983-02-25 — 1983-03-02|
|Port of departure||Ilfracombe, United Kingdom|
|Port of return||Ilfracombe, United Kingdom|
|Objectives||The programme was designed to deploy such additional measuring and recording equipment as are necessary for the first fieldwork phase of the Wave Set-up project (S36). This involved
a) further cables from the existing hut in the dunes, down the dune face and thence under the beach surface to:
i) a pair of Druck pore water pressure transducers at approximately 180m seawards of the dune face and arranged approximately 85m N and S of the existing array.
Ii) 2 transducers (1 Digiquartz + 1 IOS/FM) mounted on low profile tripod rigs some 700m seawrads of the dune face (some 200m seawards of LWMST)
b) substitution of the existing 180m Druck transducer by a Digiquartz absolute transducer.
C) removal of the upper (30m and 80m) Druck transducers, the cables of which had been damaged, probably by people with metal detectors. (To be reaplced in due course)
d) installation of new logging equipment in the dune hut.
E) carry out routine topographic survey, and determine height and position of rigs, marker buoys and beach transducers using trisponder, EDM and Ni025 level.
