When one imagines the ocean, one might think of the vastness and mysterious it offers. This is why it is one of the most difficult environments for a geologist to study and gather samples from. A scientist who studies the different natural processes that on both beaches and ocean floors are referred to as marine geologists. A marine geologist may collect samples of sediment and rock determining their ages and compositions. Traditional ways of gathering samples isn’t a luxury against the vastness and pressure present with the ocean, this is why special tools and techniques are needed to help collect samples and begin to understand the hidden features the sea has to offer.
Samples of material allow marine biologists to better understand the layers of the rock and the process of creating them. Getting a core sample and studying it is one way to gain this information. To get the sample is the tricky part though. In some cases, a weighted pipe or tubing can be lowered to the oceans bottom where samples are collected. A “gravity corer” might offer a simpler method, for it drills into the oceans floor offering a solid core sample. Benthic Landers can detect chemical compositions of the water and gather other samples and are later analyzed to see what kind of processes take place in that given area. A tool called a gravimeter can determine the density of rocks and their contents by detecting magnetic forces within them. A magnetometer could also aid in information further understanding the composition of a rock by determining its magnetic fields.
With the tools stated above, a marine geologist might hope to gain information on the age and compositions of core samples. Analyzing this information may be done in a laboratory where information would be recorded appropriately. Taking these core samples and recording data is important because it helps better understand volcanic activity, plate tectonics, floor spreading, and weatherization. Concentration could be set on the understanding of the composition of the samples as well. Movement, prevalence’s and changes over type are tracked in these ways. The work marine geologists do ultimately gives us a better understanding of the ocean.
