| Benchmarks | |
| Tide gauge benchmarks | BM2: SS disc, no markings, at base of radio tower, 72.5ft west of BM1. |
| Auxiliary benchmarks | BM3: SS disc, 'BM3' in concrete, 12ft west of tide staff along quay, 2 inches below surface elevation, concrete block 12x12 inches, 2ft from edge of quay. Likely to be covered by loose sand and rocks. BM1: SS disk marked 'BM 1 1977' in concrete 3ft N of tide well set in base of tide station; in cement supporting Handar antenna. Destroyed Sept 1989. Concrete slab broken later repaired - level has changed. |
