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]

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]
