The most frequently used method to investigate sediment and rock layers of the sea floor is through the use of seismic surveys. These surveys involve sending sound waves into the seabed and recording the reflected waves to create images of the sub-seafloor geology. This method helps scientists understand the structure and composition of sediment and rock layers beneath the ocean floor.
Wave base is typically measured as the depth at which wave action is felt on the seafloor. This is commonly determined by the distance between the wave crest and the seafloor. One method is to analyze sediment samples to identify the depth at which there is a transition from well-sorted to poorly-sorted sediments, indicating the influence of wave energy.
Radiometric dating using isotopes of elements such as potassium and argon is commonly used to determine the age of seafloor samples recovered by the deep-sea drilling project. This method calculates the age by measuring the ratio of parent to daughter isotopes in the samples.

The scientific method... Assuming they still call it that.
The best method for removing red wine sediment from a bottle before serving is to carefully decant the wine into another container, leaving the sediment behind in the original bottle.
