Brexit Within this remit, the MCA has overall may be upon us, but we are as open as ever to responsibility for the UK’s hydrographic collaborative opportunities going forward as we obligations under the Safety of Life at Sea have ever been, within the UK and with Convention (SOLAS) but works in close European partners. From the MCA’s partnership with the UK Hydrographic Office perspective, this greater collaboration results in (UKHO) to ensure that these obligations are more information getting on to nautical charts. met. It is very gratifying therefore, to see the The MCA manages a multi-million pound continued growth of attendance at CHAS and budget to systematically survey the waters the continued willingness of organisations to around the UK. This programme is known as co-operate and collaborate to minimise the the “Civil Hydrography Programme” (CHP). duplication of survey effort between Under the CHP, commercial contracts are let to organisations, wherever possible, and to realise ensure accurate hydrographic information is the benefits that brings. gathered for updating the nation’s nautical charts and publications.

Civil Hydrography Annual Seminar 2019 How the MCA gathers hydrographic data Hydrographic survey is the process of gathering a wide variety of data for the purpose of describing the seafloor. To ensure that data is collected to the highest possible quality for navigational charting, the MCA specify the following requirements. Standards Quality Assurance All surveys are conducted to the IHO Order 1a Data Quality Control survey standard, as defined by the • In addition to QC procedures employed by International Hydrographic Organisation (IHO) CHP survey contractors, technical publication ‘Standards for Hydrographic personnel from both the MCA and UKHO Surveys, Special Publication S44, Edition 5’, routinely visit contractors’ vessels with the exception of single-beam throughout survey operations to verify data echosounder (SBES) check lines under the quality.

Civil Hydrography Annual Seminar 2019 Propose a Survey Should you know or be aware of any areas of UK seabed that require update to the nautical charts and publications that cover them, please let us know. The MCA assess CHP survey areas using a contemporary risk-based methodology, but we are keen to receive any information that can aid us in our responsibilities to the mariner and the safety of life at sea. E-mail your suggestions for hydrographic survey to: hydrography@mcga.gov.uk. Typical indications of an area requiring re-survey are: • Old underlying survey data (check using the "Source Data Diagram" on the latest chart); • A change in traffic patterns (e.g. increases in cruise ship visits); • An accident occurring due to inaccurate or incomplete survey data; or • Changes to the seabed due to sandwave movement / channel migration.

Civil Hydrography Annual Seminar 2019 Survey Safety Much of the hydrographic work completed by the CHP is undertaken by contractors who are required to gather seabed data using their own personnel, and vessels owned or chartered by themselves.

Repeat inspections are undertaken annually for the duration of MCA contracts. Hydrographic Notes Reports of any newly discovered dangers to surface or sub-surface navigation are passed immediately by the CHP contractors to the MCA and UKHO using the H102 Hydrographic Note form. The nature of the CHP means that H-Notes are regularly sent in. This information is then immediately passed on to the mariner. During survey operations in 2018/19, over 160 H Notes were submitted. Wreck Investigations All wrecks found in a CHP survey are investigated with additional lines and detailed bathymetry and water column data. Sitting proud of the seabed, wrecks and other man-made obstructions often form the critical depth in each area of seabed. It is therefore crucial we have confidence that the shoalest point on these obstructions are found so the mariner can navigate safely. 11
Civil Hydrography Annual Seminar 2019 Sharing Data with the MCA If you are considering performing a hydrographic survey and are willing to share your data with us, we can pass it on to the UK Hydrographic Office to help them compile new or updated nautical charts and so help improve safety for mariners. Your survey does not need to be carried out to full charting standards to be of use. Even without a full search for dangers, a modern survey can improve on our knowledge of the seabed. There will be no legal liability on you for the way that we use your data. The MCA are always happy to give help and advice on hydrographic data gathering requirements in order to increase the usefulness of hydrographic survey data. Ideally bathymetry data would be rendered and delivered in digital form, with: • Data in one of the following: CARIS HDCS A report of the survey that describes how the directory (i.e. “HIPS”), Generic Sensor data was gathered and processed would be of Format, Fledermaus PFM or ASCII xyz use, especially if it includes: • Spurious data cleaned from the final, • A list of the equipment and software delivered, dataset with rejected used; soundings included, but flagged as • How positioning equipment was set up, deleted calibrated and used; • Details of the method used for data- • How the echo-sounder transducer was cleaning set up and levelled, together with all • Digital data as full density (i.e. prior to sensor offsets; any gridding or binning being applied), • Details of the horizontal datum to which though if gridded datasets have been the positions are referred (or the grid, if created then please include these too appropriate); • The soundings reduced using observed • How tides were measured, how the tide tides (not predicted tides from Tide pole or tide gauge was levelled and how Tables) depths were reduced to chart datum. • Depths referenced to Chart Datum for the area.
