Diving Fieldwork Summary

At the start of the first diving session, unfavourable weather conditions forced MV Flatholm to stay in Lowestoft, so that the diving equipment had to be mobilised in Lowestoft instead of Shoreham as planned. Five days fieldwork time were lost due to weather at the start of the session.

The remaining session was spent on site 5013, the so called ‘Bottle Wreck’. On the second session, the equipment was mobilised and demobilised in Shoreham. Two wrecks, site 5009, the ‘1906 Wreck’ and site 5004, the ‘Concha’ were surveyed.

Altogether 55 dives were conducted on three different sites in 19 days. Nine days were down days due to bad weather or technical defects. The total bottom time for the 55 dives is 2295 minutes or 38.25 hours. The table below provides further details on the sites that were dived:
