Tidal bundle Tidal bundle A tidal bundle is a sedimentary structure that forms in tidal areas as a result of spring and neap tides. A tidal bundle sequence can be seen as a variation in bed thickness with a periodicity of 14 days (diurnal) or 28 days (semidiurnal). During the neap tide, when the tidal current strength is weakest, smaller quantities of finer grains are deposited. As the tidal variation grows larger, towards the spring tide, larger quantities of coarser material will be deposited which results in an increasing bed thickness. Bed thickness will be greatest at the spring tide and then
Protocol relating to the status of refugees (1967) Protocol relating to the status of refugees (1967) The protocol relating to the status of refugees of 1967 broadens the definition of the Convention Relating to the Status of Refugees of 1951. The main point of the protocol was to "grant all refugees the same status irrespective of the effective date of the 1st of January 1951."
