Sediment traps collect particles that fall to the sea floor, providing valuable information about the ocean and marine life. There are three types of traps: floating, moored, and surface. Samples can be compromised if the trap location is incorrect or zooplankton consume them. Sediment traps stay submerged for nearly a year and are made of titanium.
A sediment trap is a type of large container that has been used by scientists since the late 1970s to collect samples of small and large particles that fall to the sea floor. The trap acts as a kind of filter for the water, collecting and storing various particles and elements for later analysis by researchers. Sediment traps provide a wealth of valuable information about the ocean and the marine life that inhabits it.
There are three types of sediment traps that scientists use: floating traps, moored traps, and surface traps. A floating trap that moves freely through ocean water at different depths and is designed to catch sediment drifting in the ocean current. Information about the sediments found in the floating traps allows researchers to investigate which nutrients and elements create good fishing grounds as certain particles are pushed through the current.
A moored sediment trap is tied to weights on or near the ocean floor and collects sediment which gives scientists a greater understanding of how and in what quantities different elements and nutrients reach near-bottom plant and fish life. Surface traps provide information on how nutrients and elements travel from the ocean surface to greater depths and allow for a comparison of surface sediment and floor sediment.
While in the water, a sediment trap must remain upright to function properly. Sediment samples can and indeed can be compromised if the trap location is not correct for an extended period of time. Samples can also be compromised in cases where zooplankton, small living organisms found in ocean water, permeate the sediment trap filter and consume samples, although this is more common in traps placed closer to the bottom of the ocean. Ocean.
The length of time that sediment traps stay submerged varies, but most of the time they stay in one place for nearly a year. Sediment traps are equipped with retrieval beacons and often have other technologies housed within or on the trap itself to provide additional information about changes in water conditions or the angle of inclination of the trap. The sediment traps are constructed of titanium, which allows for long-term use and immediate redistribution after sample collection.
