PEOPLE OF COLOR IN THE GEOSCIENCES
In light of the recent death of George Floyd and the following #BlackLivesMatter protests, I feel it is appropriate and necessary to highlight geoscientists of color.
I do not fully understand the struggles that are faced by people of color in this country, but I’m listening. Your pain is real. Your protests are valid.

The biostratigraphy of the offshore Niger delta during the Late Quaternary: Complexities and progress of dating techniques
Microfossils like the foraminifera and nannofossils can be used to assign relative age of sedimentary layers, which can be used to study how the Niger Delta formed.

Nature of the seismic lithosphere‐asthenosphere boundary within normal oceanic mantle from high‐resolution receiver functions
Through study of vibrations passing through the Earth, it is possible to get an image of the structures of the Earth’s interior – a little bit like how and ultrasound allows us to see inside a person’s body. In this study, the authors looked closely at the transition between the Earth’s lithosphere (the outermost layer of the Earth) and the asthenosphere below it and at how the two layers transition from one to another.

Role of soil erosion in biogeochemical cycling of essential elements: Carbon, nitrogen, and phosphorus
Soil erosion affects the cycling of essential elements in the Earth, including carbon dioxide. Erosion therefore has an important effect on the Earth’s climate.
