Tidal bundle decreases as the tidal variation grows smaller, towards the neap tide again and the thinnest beds. The presence of tidal bundles depends on the presence of spring and neap tides, which can only occur in three-body gravitational systems (the Earth, the Sun and the Moon). Therefore, the earliest time from which tidal bundles can be identified gives a conclusive lower bound on the age of the Moon. 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
Threats to sea turtles Fisheries often use large-scale nets and hook systems that are indiscriminate and catch whatever comes along, be it sea turtle, dolphin, or even shark. What is known as “bycatch” is a large contributor to sea turtle deaths, as seen in Baja California. Longline, trawl, and gillnet fishing are three types of fishing with the most sea turtle accidents. Deaths occur often because of drowning, where the sea turtle was ensnared and could not come up for air. Another dangerous aspect of fishing that is common is when sea turtles inadvertently swallow sharp hooks, which can get stuck within the soft
