What is A structure-preserving numerical approach for simulating algae blooms in marine water bodies of western Patagonia about?

Patagonian fjords' area is one of the largest estuarine regions in the world. Every one of its water bodies displays a unique hydrodynamic behavior with enormous effects on the biogeochemical characteristics of the ecosystems. In this context, algal blooms are ecological phenomena of major relevance. Numerical simulation has proved to be a promising tool to understand their impacts. It has not been used for studying algal blooms in this zone. This article focuses on proposing a novel numerical model for simulating brief algal blooms occurring in water bodies of western Patagonia. The proposed model presents a trade-off between complexity and applicability since field-data sparsity in the zone discourages using more sophisticated approaches. The model is based on a two-layer description of the water column. The first layer represents the euphotic zone where an embedded biogeochemical model of NPZD-type is used to model a mass-conserving trophic web. High intensity wind drives the water column mixing, introducing an upward flux of nutrients that boosts high rates of primary production. A time-dependent Gaussian pulse is used to describe this process. Mass losses due to detritus sinki
