The extent of the global human footprint [1] limits our understanding of what is natural in the marine environment. Remote, near-pristine areas provide some baseline expectations for biomass [2, 3] and suggest that predators dominate, producing an inverted biomass pyramid. The southern pass of Fakarava atoll-a biosphere reserve in French Polynesia-hosts an average of 600 reef sharks, two to thr...

The addition of biochar to agricultural soils has been shown to improve crop productivity and sequester carbon in soils over a millennial timeline. However, little formal research has assessed the logistics or economics of transitioning to a biochar economy. This paper examines the problem of biochar application to soil. Specifically, we look at two methods of application-broadcast-and-disk and...

Populations of native fish and aquatic ecosystems have been negatively affected by the contamination of ground and surface waters as a result of various activities. Due to the ferrous chloride (FeCl2), which is used as the reducing agent for the organic synthesis reactions in the contamination of water column and sediment, iron salts may be very toxic for some aquatic organism. In order to mini...
