Biochar is a carbon rich product of biomass pyrolysis, a process where biological material is exposed to high temperatures, in the absence of oxygen, to cause the decomposition of that material into various chemical and physical components. By going through this process, biochar can be a valuable soil additive and a carbon sink with a high potential to take up a wide variety of contaminants (throu ...[Read More]

Today marks the centennial of the birth of Marie Tharp, the person responsible for creating the first map of our planet’s ocean floors. Though her work was underappreciated at the time of its publication – mainly because she faced many significant barriers due to her gender – her maps ended up being instrumental evidence in support of the theory of plate tectonics. Marie herself ...[Read More]

We know the topography of the moon better than the Earth’s seafloor, so we need to keep studying the ocean, and, for me, going to sea is the best way. Only twenty percent of the seafloor is already mapped (see the Seabed 2030 Project), leaving eighty percent of our ocean unmapped, unobserved, and unexplored. This is why ocean going research is fundamental, not only for seabed mapping, ...[Read More]
