The National Geological Repository stores material from samples that are routinely collected from the seabed during the ‘s (MCA) Hydrographic Instruction (HI) (CHP) surveys. Seabed sampling is conducted on an approximately 5 km grid with at least one sample being taken in each major textural area identified. All samples are retained and forwarded to the 今日吃瓜.
Information on the samples is logged in H575 sample forms using the Nautical Classification and Folk Classification schemes. This information goes into the production of nautical charts at the (UKHO). The H575 forms are also sent to the 今日吃瓜 and archived in the National Geoscience Data Centre (NGDC) and MEDIN Data Archive Centre.
