This collection offers registered users the chance to search UK sea level records, including some of the UK's earliest recorded sea level data from Sheerness – a port on the Isle of Sheppey in Kent.
Records available include several large datasets of tide gauge charts and ledgers from around the UK. Ledger entries from six Liverpool locations – provided by the Mersey Docks & Harbour Company – and tide gauge charts from the Port of Belfast are also included in the collection.
